INTRODUCTION 1.1 BACKGROUND In October 2004, the U.S. Environmental Protection Agency (EPA) Office of Pollution Prevention and Toxics (OPPT), the 3M Company (3M) and its subsidiary, Dyneon, LLC (Dyneon) (hereinafter referred to as 3M) entered into a Memorandum of Understanding (MOU) to develop an environmental assessment program for perfluorooctanoic acid (PFOA) at 3M's Decatur, Alabama facility (the Site). The goal of the PFOA Site-Related Environmental Assessment Program was to characterize sources and the presence of PFOA in various environmental media, on and off-site, associated with the operations at the Site. Concurrently, and separate from the MOU activity, 3M voluntarily carried out a concurrent sampling program for three other perfluorinated substances. These compounds are: Perfluorooctane sulfonate (PFOS) Perfluorohexane sulfonate (PFHS) Perfluorobutane sulfonate (PFBS) A work plan was developed for sampling environmental media for PFOA at the 3M Decatur, Alabama plant. Perfluorinated sulfonate (hereinafter referred to as sulfonate) samples were collected in the manner specified in the PFOA work plan. From October 2004 to April 2008, field activities were conducted in accordance with the work plan. Over 1,000 environmental samples were collected for sulfonates analysis from the following environmental media: On-Site Groundwater. Soil. Vegetation. Small mammals (serum and liver). Surface water. Sediment. Sanitary wastewater from the 3M Decatur plant. 3M wastewater treatment plant effluent.

Surface water (Tennessee River and Bakers Creek). Sediment (Tennessee River and Bakers Creek). Porewater (Tennessee River sediment). Fish (whole body and fillet from Tennessee River and Bakers Creek). Clams (Tennessee River and Bakers Creek). Public drinking water treatment plants at six locations along the Tennessee River. City of Decatur Utilities (hereinafter referred to as Decatur Utilities) wastewater treatment plant influent, effluent and sludge. Morgan County Landfill leachate. The data and information generated were collected using scientific practices, protocols and procedures that have been designed to ensure data of high quality, objectivity, utility and integrity. The data were used to assess the presence of sulfonates in environmental media in and around the Site. This Perfluorinated Sulfonates Data Report is a robust summary of all the data and information generated. 1.2 DESCRIPTION OF HISTORIC AND PRESENT PRODUCTION OF SULFONATE PRODUCTS The manufacturing of PFOS-related substances began in the early 1960s at the 3M Decatur, Alabama site. Production of these substances continued until 2001 following the voluntary phase-out announcement by 3M in May 2000. Production of PFOS-related products and PFHS-related products occurred over this timeline with the former products representing the bulk of the production. Following the production phase-out, 3M began production of PFBS-related substances after obtaining approval from EPA pursuant to the Premanufacturing Notice (PMN) requirements under the Toxic Substances Control Act (TSCA). Since production of these three types of perfluorochemicals either occurred historically (PFOS-related and PFHS-related) or is occurring currently (PFBS-related), the ultimate degradation end products of these substances were the focus and the specific compounds J:\3M -D E C A T \P F O S \F IN A L \T E X T \S U L F O N A T E _ D E C A T U R _ F N L _ S E C 1 T O 3 .D O C 9 /1 6 /2 0 0 8 1-2 analyzed as part of this assessment program. Thus, the three compounds analyzed were perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHS) and perfluorobutane sulfonate (PFBS). 1.3 REPORT ORGANIZATION This PerfluorinatedSulfonates Data Report is organized into the following sections: Section 1 - Introduction.

ENVIRONMENTAL SETTING 2.1 SITE LOCATION AND BACKGROUND INFORMATION As shown in Figure 2-1, the 3M Decatur, Alabama facility is approximately 2 miles northwest of the City of Decatur along the south bank of the Tennessee River and at the intersection of State Highway 72 with Finley Island Road and State Docks Road. The Decatur area has a significant industrial base. Many industries are located on the banks of the Tennessee River near the 3M Decatur facility and are visible from the river. Along the southern bank of the river immediately to the east of the 3M facility are the Cargill, Inc., State Docks Road industrial park, and Solutia properties, and immediately west of the 3M facility is the BP Chemical (BP) property. Figure 2-2 depicts the locations of site features that are mentioned in the following sections. 3M began operations at the Decatur, Alabama facility in 1961 with the construction of the chemical manufacturing plant (Chemical Plant). In 1962, the facility was expanded to include a film manufacturing plant (Film Plant). As shown in Figure 2-2, the Dyneon facility is located on 3M's manufacturing site. Process wastewater from 3M plant operations has always been treated in an on-site wastewater treatment plant (WWTP). The treated water is discharged from an outfall to Bakers Creek under a National Pollutant Discharge Elimination System (NPDES) permit. After a short distance, Bakers Creek flows into the Tennessee River. Sanitary wastewater is separate from the process wastewater and is conveyed off-site to the Decatur Utilities Dry Creek WWTP for treatment prior to discharge to the Tennessee River. From 1978 to 1998, 3M incorporated sludge from the on-site WWTP by means of subsurface injection in an on-site area designated as the sludge incorporation area. This activity was conducted under an NPDES permit. The sludge was generated at the on-site WWTP from treatment of manufacturing facility wastewater. The former sludge incorporation area comprises approximately 575 acres on the southern portion of the J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-1 9 /1 6 /2 0 0 8 facility property. Further discussion on the former sludge incorporation area is provided in Section 2.5. 2.2 TOPOGRAPHY AND DRAINAGE An understanding of site topography and drainage is integral to the identification and characterization of potential surface transport pathways. The shape and slope of the land surface directs the overland flow of water and suspended particles during a precipitation event. Additionally, surface features may provide information on subsurface conditions. For example, subsurface flow of groundwater in a bedrock fracture erodes the bedrock and creates a depression. When soil forms over the rock surface, the depression is maintained and can be seen at the ground surface. Thus, the following description of the Decatur site topography and drainage is provided to facilitate an understanding of potential surface migration pathways for sulfonates and serve as background for the characterization activities. The 3M Decatur facility is located in the Highland Rim section of the Interior Low Plateau's physiographic province. This province is characterized by gently rolling hills, broad low drainage divides, and gentle stream gradients. Topographic elevations of the site range from approximately 550 feet above mean sea level (ft msl) near the Tennessee River to 635 ft msl in the west-central portion of the site. Surface water discharges from the property by means of several manmade ditches. Surface water and storm runoff from non-process areas in the northern half of the site is directed to several outlets that drain to the Tennessee River. Surface runoff in the plant production areas is collected in storm drains or ditches and conveyed to the on-site WWTP for treatment prior to discharge through the site's NPDES-permitted outfall. The facility currently has 11 stormwater outfalls that are included in the NPDES permit. As shown in Figure 2-2, storm runoff from the central and southern portions of the property drains to the east, south, and west, and ultimately discharges to the Tennessee River or Bakers Creek. Immediately west of the 3M property is a drainage system, J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-2 9 /1 6 /2 0 0 8 hereinafter referred to as the Bakers Creek drainage system, which discharges to Bakers Creek. As shown in Figure 2-2, it consists of an off-site marsh (OSM), off-site swamp, and a drainageway, which extends from the swamp across the southwest corner of the 3M property and under Highway 20 to a ditch along the road that discharges to Bakers Creek. Prior to 2006, an off-site marsh well was pumped to create and maintain open water within the marsh at the Wetlands Edge Nature Center. The marsh would overflow into the swamp, which drains into the ditch that flows onto the 3M property between former sludge incorporation area Fields 10 and 14. Marsh and swamp overflow water and stormwater flow would be conveyed by this drainage system to Bakers Creek by means of the ditch along Highway 20. This ditch, in turn, discharges to the main tributary of Bakers Creek near the intersection of Highway 20 with State Docks Road. When the pumping of the off-site marsh well stopped, the area became an emergent marsh with only periodic inundation in response to precipitation events and stormwater run-on. The Tennessee River is impounded downstream of the plant by the Wheeler Dam and this forms the Wheeler Reservoir. The dam and water levels are managed by the Tennessee Valley Authority (TVA). The Tennessee River flows to the west and has a summer pool elevation of 556 ft msl and a 100-year flood zone elevation of 568 ft msl. During winter months, the pool level is lowered approximately 5 to 10 feet to help manage the increased rainfall during this period. Although eastern portions of the site lie within the 100-year flood zone, the industrialized portions of the site are entirely above the 100-year flood zone. 2.3 GEOLOGY An understanding of site geology is integral to identifying potential transport pathways in the subsurface and associated characterization activities. Certain geologic characteristics such as depth of soil to bedrock, makeup of the soil present, porosity of the soil, type of bedrock, the amount of fractures in the bedrock, etc., are considered in the selection of sampling locations for characterization of environmental media. Each subsurface feature has some influence on the movement of sulfonates from the source to environmental J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-3 9 /1 6 /2 0 0 8 media. The primary geologic features, from the ground surface to bedrock, at the 3M Decatur facility consist of the following: Residuum - The residuum is a low permeability soil material consisting of silty sand and clayey sand with varying percentages of gravel, underlain by sandy silt to clayey silt with weathered limestone fragments. The upper portions of the residuum consist of sediments that have been deposited over time by the Tennessee River drainage system. The base or lower portion of the residuum is soil consisting of completely weathered limestone bedrock (saprolite), i.e., limestone that has been completely broken down into soil components through natural physical and chemical processes. The residuum at the 3M Decatur facility ranges in thickness from 10 to 50 feet. Epikarst - The contact between the residuum and underlying bedrock is transitional. The zone of transition is known as the epikarst. It extends from the saprolite (i.e., completely weathered bedrock) to competent, intact bedrock. In this zone there is interlayering of soil and limestone fragments of varying sizes. The epikarst thickness at the 3M Decatur facility is highly variable and ranges from a few feet to greater than 50 feet. Bedrock - The bedrock underlying the 3M Decatur facility is the Tuscumbia limestone unit. Fractures within this unit occur primarily along bedding planes, and typically do not exceed 10 millimeters (mm) in thickness. The occurrence of fractures decreases with depth. A detailed discussion of these geologic features is provided in the following subsections. 2.3.1 Regional Geology The geology of Morgan County typically consists of unconsolidated soil underlain by a stratigraphic sequence of consolidated limestone, chert and shale. 2.3.2 Site Geology Geology at the 3M Decatur facility includes an unconsolidated residuum overlying a stratigraphic sequence of competent carbonate and shale units. The major geologic units are described in the following sections, and a generalized stratigraphic column is depicted in Figure 2-3. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-4 9 /1 6 /2 0 0 8 2.3.2.1 Residuum and Epikarst Unconsolidated soil at the 3M Decatur facility consists of an upper sequence of alluvial sediments followed by saprolite associated with the underlying bedrock. Collectively, this sequence of soil is referred to as the residuum. The upper alluvial sediments consist of red to brown sandy silt to sandy clay with varying amounts of rounded to subrounded chert gravel. Textural features observed in split-spoon samples and within outcrops along Wheeler Reservoir indicate that the soil was deposited by the Tennessee River drainage system. The soil typically underlies the topographic highs at the facility and ranges in thickness from 10 to 50 feet. Underlying the alluvial sediments is a yellowish-brown to reddish-brown silty clay to clayey silt. Sand lenses of fine- to medium-grained, well-sorted rounded quartz are observed locally. Angular, weathered (soft stone) to competent white chert up to several inches in diameter is common and typically increases in percentage with depth. In samples collected at the interface with the underlying competent bedrock, the chert may be observed comprising up to 60 percent of the soil by volume. In early investigations at the site, this horizon was referred to as a rubble zone. The epikarst is that portion of carbonate bedrock that exhibits transitional weathering from completely weathered rock (saprolite soil) to competent limestone bedrock. Boring data at the site indicate that the thickness of the epikarst is highly variable and ranges from a few feet to greater than 50 feet. The epikarst has been shown to represent a significant water transfer hydrologic zone for the site. 2.3.2.2 Bedrock Stratigraphy Bedrock underlying the 3M facility has been interpreted based on core samples collected from the site and current published information. The following sections present a brief summary of the bedrock stratigraphy at the site from youngest to oldest. Tuscumbia Limestone - Drill cores indicate the uppermost bedrock at the 3M facility as Tuscumbia Limestone. The Tuscumbia Limestone consists of Mississippian-age gray to light-gray bioclastic limestone and gray micrite (fine-grained carbonate mudstone) with J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 2-5 9 /1 6 /2 0 0 8 occurrences of chert nodules (Butts, 1926; Thomas, 1972; Kugler, 1994). This bedrock unit at the 3M Decatur site is approximately 90 feet thick and consists of oolitic bioclastic limestone, bioclastic limestone and micrite that appear to be stratigraphically correlative throughout the site. Fort Payne Chert - Drill cores indicate a sequence of dense, dark gray cherty limestone approximately 130 feet thick, at an elevation of approximately 300 feet msl to 440 feet msl. Butts (1926) describes the Fort Payne Chert as massive dark gray chert to brownishgray siliceous micrite (limestone). The contact between the Tuscumbia Limestone and the Fort Payne Chert units at the 3M facility has been established at approximately 440 feet msl. This horizon represents the top of a lithologic zone approximately 10 feet thick consisting of brown, fine-grained asphaltic dolostone (micrite) with abundant light gray chert nodules. The unit was identified in multiple boreholes at the facility and within a quarry approximately 2 miles west of the site, indicating that it represents a mappable unit for the area. The chert within the zone is highly fractured and angular and contains voids lined with quartz, dolomite and fluorite. Many of the voids are also filled or partially filled with a black to brown viscous fluid identified through laboratory analysis as low-grade asphaltic crude. The material was also observed filling micro-fractures within the matrix of the rock. Maury Shale - Rock interpreted as the Maury Shale was observed at the Decatur facility. The rock consists of dark green to greenish gray fossiliferous shale with abundant glauconite and occasional dark gray to black phosphate nodules. The Maury Shale represents the basal Mississippian-age unit for the Black Warrior Basin in Alabama. The unit lies unconformably above the Chattanooga Shale and is described as greenish-gray glauconitic shale with phosphate nodules. The unit is generally 2 to 3 feet thick and may be locally absent (Kugler, 1994). The lower contact with the Chattanooga Shale is sharp with abundant sulfides. The upper contact with the Fort Payne Chert is less pronounced (transitional) and identified primarily by a loss of chert. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-6 9 /1 6 /2 0 0 8 Chattanooga Shale - The lowermost unit encountered during drilling operations at the 3M facility is the Chattanooga Shale. This unit was encountered in bedrock cores from locations 212D and 217D at an elevation of approximately 300 feet below mean sea level. This Upper Devonian-age unit is generally described as black fissile, pyritic shale with graded siltstone beds containing current ripples, horizontal laminae, and feeding burrows (Kugler, 1994; Butts, 1926). Amber brown kerogen (a solid, bituminous mineral oil substance in oil shales that yields oil when subjected to destructive distillation) is common, as well as fossils of algal origin. Siltstone bedding laminae are common and may be locally pyritic. Bedding was the primary structural fabric observed. Fractures that could be interpreted as water-bearing were not observed within this unit. Interbeds of cemented algal matter (oncolites) were also observed. 2.3.3 Structural Interpretations Compilation of available bedrock and well construction data for the facility indicate that zones of increased bedrock fracture frequency occur within specific elevation ranges in the bedrock. The occurrence of fracturing may be controlled, in part, by the textural variations of the rock. Fractures observed within the Tuscumbia Limestone appear to be dominated by bedding-controlled fractures, although oblique fractures are common. Though largely filled during secondary recrystallization of the rock, open fractures were observed with clay and oxide residues to suggest water movement. Below the Tuscumbia Limestone, the frequency of fracturing decreases significantly. Bedding-Controlled Fractures - The most prominent fracturing observed within the Tuscumbia Limestone is bedding-controlled. The fractures are observed most often along black, stylolitic bedding laminae that are common within the bioclastic portions of the rock. Some of the fractures contain clay, metal oxide residues and secondary crystallization to suggest water movement. The thickness of the fractures ranges from less than 0.5 mm to approximately 10 mm. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-7 9 /1 6 /2 0 0 8 Within the epikarst, fractures are more developed and appear to control preferential dissolution of the bedrock. Open voids have been encountered within the epikarst (monitor wells 130L, 511S and 215D) up to 6 feet in diameter capable of significant yields of groundwater. Oblique Fractures - High-angle oblique fractures have been observed in core samples of the Tuscumbia Limestone. The fractures generally occur as a series of small parallel fracture sets approximately 3 to 5 inches apart within a zone of approximately 2 vertical feet. In most instances, the fractures are filled with calcite or silica. However, some are observed with open voids that would allow vertical groundwater migration. The fractures are often truncated by bedding fractures within a few feet, suggesting that individual oblique fractures do not represent significant structural features for the site. The fractures appear to present areas for preferential weathering of the bedrock. Outcrops of bedrock along Wheeler Reservoir suggest that oblique fractures may control the formation of vertical crevices within the epikarst. Crevices up to 20 feet in depth have been encountered during drilling (well 216R). The features are presumed to be due to preferential dissolution along oblique fractures. Data collected from oriented coring at the site suggest that the oblique fractures reflect a regional joint fracture system with a northwest to southwest strike and southwesterly to southeasterly dip. Recent pump test data for the Decatur facility indicate preferential flow of groundwater within the epikarst zone that may be controlled by increased weathering along local joint fracture systems. Figure 2-4 presents an interpretation of apparent bedrock fractures using coring, pump test data and observation of ground surface features (i.e., fracture trace analysis). This fracture trace analysis was one of the tools used to locate groundwater recovery wells in the Chemical Plant area along the interpreted bedrock fracture adjacent to monitoring wells 310R and 317L. Figure 2-5 illustrates the bedrock topography as interpreted from soil borings, monitoring well borings, and coring data collected from previous investigation at the facility. The plot indicates the current bedrock surface is irregular, expressed as a series of depressions J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 2-8 9 /1 6 /2 0 0 8 and ridges that mimic surface topography. Topographic lows reflect depressions within the bedrock surface that are presumed to be produced either by increased susceptibility to chemical weathering, physical erosion by the Tennessee River system, or both. 2.4 HYDROGEOLOGY An understanding of site hydrogeology is integral to identifying potential groundwater transport pathways in the subsurface and associated characterization activities. Geologic characteristics described in the previous section influence the flow of subsurface groundwater and constituents that are dissolved or suspended in it. The primary water-bearing zones (in order from shallow to deep) that are evident at and adjacent to the 3M Decatur, Alabama facility include the following: Residuum - The residuum shallow water-bearing zone (water table) is found within the unconsolidated soil consisting of an upper sequence of alluvial sediments followed by saprolite associated with underlying bedrock. Wells screened into this unit are designated with an "R", e.g., 137R. Epikarst - The epikarst middle water-bearing zone is found within that portion of carbonate bedrock that exhibits transitional weathering from completely weathered rock (saprolite residuum soil) to underlying competent limestone bedrock. Of the three water-bearing zones, the epikarst is more transmissive and tends to be the preferred pathway for lateral groundwater flow. Wells screened into this unit are designated with an "S", e.g., 137S. Bedrock - The bedrock water-bearing zone is found within the fractures and solution cavities of the limestone bedrock. Wells screened into this unit are designated with an "L", e.g., 137L. A detailed discussion on the hydrogeology at and in the vicinity of the 3M Decatur facility is provided in the following subsections and is followed by a summary of key hydrogeologic findings. 2.4.1 Regional Hydrogeology The Tuscumbia-Fort Payne aquifer represents the primary aquifer system for Morgan County and is comprised of the Tuscumbia Limestone and Fort Payne Chert. Primary porosity in the unweathered Tuscumbia Limestone and Fort Payne Chert is low, J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 2-9 9 /1 6 /2 0 0 8 averaging less than a few percent of the total volume of rock. As a result, groundwater occurs within secondary porosity features including oblique fractures and bedding plane fractures, and solution features near the bedrock surface (epikarst zone). Groundwater flow associated with this system is controlled by the number, extent, orientation and interconnection of these water-bearing fractures. Bedrock groundwater flow in the site area is generally to the north toward the Tennessee River. The Tuscumbia-Fort Payne aquifer is considered a primary aquifer for public drinking water supplies in many areas of northern Alabama, with well yields ranging from approximately 40 gallons per minute (gpm) to greater than 2,000 gpm. Locally, however, the aquifer is not permeable and does not yield significant quantities of groundwater. In the area of the 3M property, average yields from wells within this aquifer system are less than 0.5 gpm. As a result, the Tuscumbia-Fort Payne aquifer is not used at the 3M facility or by the City of Decatur as a water supply source. Potable water used at the site, and in the Decatur area in general, is provided by Decatur Utilities, the municipal water system whose source is from the Tennessee River surface water, upstream from the 3M facility. Towns downstream of the facility also use the Tennessee River as a potable water supply source. Wells completed within the residuum generally yield less than 1 gpm. As a result, the residuum unit is not considered as an economical water source. Regionally, the residuum serves as a recharge zone for the underlying Tuscumbia-Fort Payne aquifer. 2.4.2 Site Hydrogeology Data collected from the 3M Decatur facility indicate that the local hydrogeologic system may be divided into the following hydrostratigraphic zones: Perched water zones. Unconfined residuum water-bearing zone. Unconfined to semi-confined epikarst water-bearing zone. Semi-confined fractured limestone water-bearing zone. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-10 9 /1 6 /2 0 0 8  Underlying sequence of massive bedded chert and limestone that constitutes a basal confining unit. The degree of hydraulic communication between the water-bearing zones is dependent on local conditions, such as the presence of physical features (fractures, faults, erosional features associated with the Tennessee River system) and weathering within the epikarst system. The potentiometric data for the site indicate that groundwater occurs under both unconfined and semi-confined conditions. Perched groundwater has been documented at the 3M Decatur facility associated with artificial and natural soil horizons that result in an abrupt change in soil permeability impeding vertical flow though the soil. Artificial horizons are often created by placing fill material within depressions or over existing grade. Examples of these artificial horizons have been identified in the northern portion of the facility (Chemical Plant area) at the North Tank Farm and at the on-site closed inactive landfill. Natural perched zones have been identified associated with the contact of alluvial sediments and underlying bedrock saprolite within the residuum zone and at the point of contact with competent rock (top of epikarst). Perched groundwater at the facility is localized and does not appear to represent a significant feature in groundwater movement at the site. The residuum hydrostratigraphic zone consists of the water table aquifer within the unconsolidated soil at the site. The zone appears over most of the site to be transitional or interconnected with the epikarst zone, and is primarily an unconfined aquifer system. Site data indicates that groundwater flow within this zone is most developed at the base of the soil column associated with the contact with first competent rock. This horizon is often reflected by a concentration of residual chert gravel to boulders. The epikarst zone at the site has been defined as a zone of weathering bedrock extending from the point of first encountered competent rock in the subsurface to the point of competent bedrock. The thickness of this zone varies considerably from a few feet to greater than 50 feet in thickness. In most areas, this zone has been shown to be connected to the overlying residuum and underlying bedrock bedding fractures intercepted by vertical weathering within the epikarst system. This zone may be J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 2-11 9 /1 6 /2 0 0 8 characterized as a highly variable interlayering of competent to partially weathered bedrock and completely weathered bedrock zones. Often, the weathered zones exceed liquid limits resulting in a highly fluid zone of mud. Dye trace investigations conducted in the Chemical Plant area at the facility suggest that these fluid zones within the epikarst serve as the primary avenue for lateral groundwater flow at the site, exhibiting flow rates of several hundred feet per day (WESTON, 2003). Competent bedrock at the site begins within the Tuscumbia Limestone. Drill core data collected at the site indicate this sequence of rock contains both oblique and beddingcontrolled fractures capable of groundwater transfer, although bedding-controlled fractures appear to be more prevalent. These fracture systems decrease with depth and are rarely observed within the underlying Fort Payne Chert. Potentiometric data indicate that these systems are connected to overlying hydrostratigraphic zones likely due primarily to the physical interception of bedrock fractures by weathering within the epikarst system or physical erosion by the Tennessee River system. The degree of communication between this zone and overlying zones is dependent on the extent of epikarst development or complexity of the bedrock surface profile, but typically may be regarded as a semi-confined aquifer system. Figures 2-6, 2-7 and 2-8 contain groundwater elevation contour maps for the residuum, epikarst and shallow bedrock at the Decatur facility. The residuum plot (Figure 2-6) indicates groundwater elevations ranging from 616.68 ft msl at well 133R (in Field 6 of the former sludge incorporation area) to approximately 552.10 ft msl at well 308R adjacent to the Tennessee River (Wheeler Reservoir) and 557.18 ft msl at well 119C in Field 14 of the former sludge incorporation area. Groundwater data collected in February 2007 indicate that residuum groundwater flows radially from the area of Field 6 in all directions and is influenced largely by the local surface water drainage systems. To the north, groundwater flows toward the primary manufacturing areas of the facility. Flow may be influenced by an east to west trending fracture, resulting in a shift in flow to the northeast toward the discharge point of Bakers Creek into the Tennessee River. Flow to the south from the Field 6 area appears to be influenced by a secondary tributary that J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-12 9 /1 6 /2 0 0 8 directs flow to the southeast toward Bakers Creek. The inferred flow of residuum groundwater immediately southwest of the Site and at Field 14 is northeast towards the on-site drainageway. Figure 2-7 presents a groundwater elevation contour map constructed for the epikarst unit using data collected in February 2007 across the former sludge incorporation area. Recent groundwater monitor wells in the former sludge incorporation area have been installed to isolate the epikarst unit. The general direction of groundwater flow in the epikarst across this area is similar to the residuum unit as shown in Figure 2-6. A groundwater high exists near the center of the property (well 133S) with groundwater flowing radially away from this location. Groundwater flowing to the west is influenced by the secondary tributary that directs flow to the southeast toward Bakers Creek in this area. The February 2007 groundwater elevation data indicates a trough present in the epikarst groundwater surface in the southwest corner of the property. The inferred flow of epikarst groundwater west and south of the Site is eastward, generally towards the on site drainageway. Potentiometric data for the shallow bedrock (Figure 2-8) indicates groundwater elevations ranging from 606.47 ft msl at well 133L (in Field 6 of the former sludge incorporation area) to 554.78 ft msl at well 130L (west in Field 9 of the former sludge incorporation area) and 549.51 ft msl to the north at well 307L. As with the residuum, groundwater within the shallow bedrock flows radially from the area of Field 6. However, the data suggest that there is a westerly flow component toward the BP property associated with this hydraulic zone independent of the Bakers Creek drainage system. Also, the groundwater elevation observed associated with well 307L appears to be influenced by the groundwater recovery system (installed as part of a nonfluorochemical remediation system) that is operating at wells 312R and 331S in the Chemical Plant. The groundwater recovery system is creating a depression in the groundwater surface in this area. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-13 9 /1 6 /2 0 0 8 2.4.3 Summary of Key Hydrogeologie Findings The following is a summary of the key hydrogeologic findings for the 3M Decatur facility: The water-bearing zones (in order from shallow to deep) that are evident at and adjacent to the 3M Decatur, Alabama facility include: - Residuum: The residuum shallow water-bearing zone, also referred to as the water table, is found within the soil layer. - Epikarst: The epikarst middle water-bearing zone is found within the portion of bedrock that exhibits transitional weathering from completely weathered rock (i.e., saprolite residuum soil) to underlying competent bedrock. - Bedrock: The bedrock water-bearing zone is found within the fractures and solution cavities of the limestone bedrock. Groundwater Flow Direction In the southern portion of the former sludge incorporation area, groundwater in each of the three water-bearing zones generally flows radially from Field 6 to the east, south and west. Groundwater flowing east is toward Bakers Creek. The residuum and epikarst groundwater, flowing south and west, appear to be intercepted by the drainage system in the southwestern portion of the Site, which directs flow to Bakers Creek. The bedrock groundwater flowing south and west does not appear to be influenced by this drainage system and flows westward toward the BP property. In the northern portion of the former sludge incorporation area (Fields 12 and 13), groundwater flow is to the north and west. In the southwest corner of the former sludge incorporation area, a drainage ditch separates Field 14 (a control field) from the rest of the fields. Hydrogeologic data suggest that this drainage feature intercepts residuum groundwater that flows in a northerly direction in Field 14 and residuum groundwater from the remainder of the adjacent fields that flows in a southwesterly direction. The groundwater gradient within the bedrock groundwater is not affected by the Field 14 drainage feature and tends to flow to the northwest and west. In the northern portion of the 3M Decatur facility (north of Avenue A), groundwater flow is to the north and northeast toward the Tennessee River and Bakers Creek. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-14 9 /1 6 /2 0 0 8 - In 2006, a groundwater recovery system was installed into the epikarst/shallow bedrock at two wells in the Chemical Plant area under a non-fluorochemical remediation program. The groundwater elevation observed at bedrock well 307L appears to be influenced by the groundwater recovery system in the Chemical Plant, which is creating a depression in the groundwater surface in this area. A second groundwater recovery system was installed at the former incinerator pad into the residuum zone, but it pumps at a low rate and has less influence on groundwater elevation than the Chemical Plant system. - The Tennessee River is a hydraulic barrier to groundwater flow to the north. This is supported by a flow net analysis performed as an earlier hydrogeological investigation at the site, which indicated that the majority of groundwater discharge from the Chemical Plant area into the Tennessee River would be within 200 feet of the facility's shoreline. The Tennessee River is approximately 3 miles wide adjacent to the facility. Other Key Findings Groundwater elevations within the former sludge incorporation area indicate restricted downward vertical movement between the three groundwater zones with vertical communication occurring only in localized areas across the Site. Of the three water-bearing zones, the epikarst is more transmissive and tends to be the preferred pathway for lateral groundwater flow. Geologic cross sections indicate that the thickness of the epikarst zone is variable; however, in the northern part of the former sludge incorporation area (Field 9), the thickness of the epikarst zone increases moving westward toward the property line at Finley Island Road. At the former sludge incorporation area, potentiometric data indicate a groundwater high in all three zones associated with the area of Field 6. Geologic data for this Field 6 area suggest limited development of the epikarst system and poorly developed bedrock fracture systems impeding vertical flow in this area. This is in contrast to the northwest portion of the former sludge incorporation area (well cluster 130 in Field 9) where the epikarst is more significantly developed. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-15 9 /1 6 /2 0 0 8 2.5 FORMER SLUDGE INCORPORATION AREA 2.5.1 Sludge Incorporation Program From 1978 to 1998, 3M incorporated sludge from the on-site wastewater treatment plant by means of subsurface injection in an on-site area designated as the sludge incorporation area. Historically, sludge incorporation was undertaken, as an alternative to sludge disposal, to utilize the nitrogen content, organic matter, phosphorus and other essential elements contained in the sludge for soil enrichment and crop production. This activity was conducted by 3M under Alabama Department of Environmental Management (ADEM) NPDES Permit No. AL0000205. The sludge generated at the wastewater treatment plant was from the treatment of manufacturing facility wastewater and contained approximately 1 to 3 percent solids and likely contained sulfonates. Sludge was hauled by tank truck from the wastewater treatment plant to the incorporation zone. The tank truck was equipped with a series of nozzles that injected the sludge approximately one foot below ground surface. Subsurface sludge incorporation was conducted in accordance with the NPDES permit; no direct surface application of sludge was permitted or believed to have occurred. The former sludge incorporation area, located on the southern portion of the 3M facility property, consisted of 575 acres of land not used for production activities, as shown in Figure 2-2. The area used for sludge incorporation was comprised of 13 application "fields or zones" and two control fields where no sludge was applied. A diagram of these "fields" is shown in Figure 2-9. Table 2-1 provides a history of sludge incorporation activities. Based on discussions with 3M personnel familiar with the sludge disposal operations, Field 7 was the original control area until 1991. In 1991, 3M sold 95.7 acres of the land encompassing Fields 1 through 4, Field 7, and parts of Fields 6 and 8a, to Daikin Industries, Ltd. (Daikin) and 13 acres to MDA, Inc. No sludge was applied to Field 14. Table 2-2 includes a summary of the amounts of sludge applied into the various fields. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-16 9 /1 6 /2 0 0 8 In accordance with the NPDES permit, incorporation of sludge was limited to fields that were to be cropped during the next appropriate growing season. 3M discontinued land application of sludges in 1998. The former sludge incorporation area is no longer cropped, has naturally revegetated, is posted with "No Trespassing" signs and routinely patrolled by 3M security guards. Since the inception of 3M's sludge incorporation program, the facility's NPDES permit limited the amounts and characteristics of the sludge incorporated into the fields. When 3M initiated the sludge incorporation in 1978, ADEM had not published guidelines for sludge incorporation. 3M's criteria for land application of sludge was based on other existing guidance, including EPA's 1976 "Municipal Sludge Management" technical bulletin, Illinois EPA's Technical Policy WPC#3 (draft) "Design Criteria for Municipal Sludge Utilization on Agricultural Land," and Wisconsin DNR Technical Bulletin 88 "Guidelines for the Application of Wastewater Sludge to Agricultural Land in Wisconsin." The ADEM NPDES permit limits were based on the ability of the fields to incorporate nitrogen as a fertilizer and certain metals that were present in the sludge as mineral fluoride salts. Zinc, copper and nickel were the limiting metals for sludge incorporation rates. The ADEM NPDES permit required soil monitoring for zinc, nickel and cadmium. Under this permit, soil samples were also analyzed for inorganic fluorides; however, the permit did not require analysis for sulfonates. The analytical method for inorganic fluoride determination does not measure sulfonate concentrations. Cotton was the primary crop historically grown in the sludge incorporation area. The typical practice was to plant winter wheat after harvesting the cotton crop. The wheat seed was retained for future plantings, and the wheat straw left in place or tilled back into the soil. To a lesser extent, soybeans and perennial rye were also grown in the former sludge incorporation area. Soybeans and rye hay were harvested for use as animal feed. Upon cessation of land application of sludge, agricultural usage was also discontinued in J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-17 9 /1 6 /2 0 0 8 the former sludge incorporation area. None of the crops grown at the former sludge incorporation area were tested for sulfonates. The current NPDES permit only covers wastewater discharge from the on-site WWTP at Outfall 001 and eleven stormwater outfalls. Sludge incorporation is no longer practiced at the site and is not addressed in the current permit. The permit contains monitoring requirements at Outfall 001, which includes fluorochemicals as well as other parameters. 2.5.2 Habitat Identification and Ecological Resources The following information on the terrestrial habitat in the former sludge incorporation area is based on observations made during site walk-throughs conducted in September 2004 and on literature describing habitats typical of northern Alabama, the 3M Decatur facility and its surroundings. A literature review was conducted to identify the potential wildlife communities and the species present in each habitat type in the vicinity of the 3M Decatur facility. A list of potential species was created based on the known habitat requirements of each species and available habitats on the site. Observations of flora and fauna in the former sludge incorporation area fields are provided in Section 3.4.1. The former sludge incorporation area, although now in the early stages of succession, provides foraging and nesting habitat for birds, invertebrates, reptiles and mammals. The Tennessee River/Bakers Creek riparian complex supports wildlife that use more than one habitat within the study area (e.g., nesting versus foraging habitat). Birds, reptiles, amphibians, fish, mammals and invertebrates occur in the immediate riparian area and adjacent areas with suitable habitat. Birds and mammals, which may inhabit or utilize the former sludge incorporation area, were identified in a literature review. The most common songbirds include the redwinged blackbird (Agelaius phoeniceus), eastern meadowlark (Sturnella magna), eastern kingbird (Tyrannus tyrannus), American goldfinch (Carduelis tristis), mourning dove (Zenaida macroura) and various sparrow species (Passer spp.). Common mammals J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 2-18 9 /1 6 /2 0 0 8 include the hispid cotton rat (Sigmodon hispidus), white-footed mouse (Peromyscus leucopus), least shrew (Cryptotus parva), short-tailed shrew (Blarina brevicauda), eastern cottontail rabbit (Sylvilagusfloridanus), woodchuck (Marmota monax) and white tailed deer (Odocoileus virginianus). The small mammal community provides prey for apex predator species such as redtailed hawk (Buteo jamaicensis) and foxes (Vulpes sPP.). Vegetation in much of the area is dominated by herbaceous plants with some woody species entering the succession. The old fields include a mixture of native and introduced grasses. Common herbaceous species likely to be present include composite species of Aster, Ambrosia and Solidago. Early stage shrubby species beginning to colonize the area are expected to include sumacs (Rhus spp.), catbrier (Smilax spp.) and blackberries (Rubus spp.). Woody species likely to enter the succession include hackberry (Celtis spp.), winged elm (Ulmus alata), black locust (Robinia pseudoacacia), honey locust (Gleditsia triacanthus) and sweet gum (Liquidambar styraciflua).

SUMMARY OF FIELD ACTIVITIES 3.1 BACKGROUND The sulfonates sampling program was composed of the collection of data in various media and locations to characterize the presence of sulfonates both on-site and off-site. A summary of the field activities is provided in the following sections. Table 3-1 provides an overview of the sulfonates program. Analyses of samples for sulfonates (PFBS, PFHS and PFOS) were performed by the Exygen Research Laboratory (Exygen), now MPI Research, State College, Pennsylvania, and the 3M Environmental Laboratory, St. Paul, Minnesota. In addition to the sulfonate analyses, ancillary data were collected for other chemical and physical parameters. Total organic carbon (TOC) for soils and sediment, total dissolved solids (TDS) for groundwater and surface water, total suspended solids (TSS) for groundwater and surface water, and percent lipids for fish analyses were performed by Severn Trent Laboratories (STL), University Park, Illinois. Sieve/grain size analyses for soils and sediments were performed by Tuscaloosa Testing Laboratory (TTL), Decatur, Alabama. 3.2 GROUNDWATER MONITORING WELL INSTALLATION AND SAMPLING 3.2.1 Installation Twenty-four groundwater monitoring wells were installed and five exploratory soil borings drilled for collection of hydrogeologic data associated with the former sludge incorporation area. The drilling activities were conducted from October 2004 through January 2005. Borings were logged by an experienced geologist noting color, texture, moisture content, and any odors or discoloration. The boring and monitoring well locations are shown in Figure 3-1. A summary of the soil boring and well construction data is presented in Tables 3-2 and 3-3, respectively. A copy of the boring logs and well completion logs is provided in Appendix A. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-1 9 /1 6 /2 0 0 8 The groundwater monitoring wells were constructed in "nests" of three wells initially in areas associated with former sludge incorporation Fields 6, 8b, 9 and 14. Two sets of three nested wells were installed in each of the four fields for a total of 24 wells. Each well nest consists of a bedrock well, an epikarst well and a residuum well. The bedrock, epikarst and residuum well types are designated by the suffixes "L", "S" and "R", respectively, and associated with a well "nest" location number (130 through 137). All of the monitoring wells were completed at the surface with lockable protective covers and 4-foot by 4-foot concrete pads. At each of Fields 6, 8b and 9, one of the well nests was constructed in an area of the field determined to be representative of the former sludge incorporation activities associated with the field. The second well nest was constructed in an area along the margin of the field where there was no indication of sludge incorporation activities. The locations were based on field observations, interviews with site personnel and evaluation of historic aerial photography. Field 14 is a control field where no sludge was incorporated. In addition to the monitoring wells, five exploratory soil borings (131B, 133B, 134B, 136B and SB-001B) were constructed down to the water table (one each from Fields 9, 6, 8b, 14 and the northwest background area, respectively) to obtain soil profile and logs and to evaluate the homogeneity of soil conditions. The northwest background area is located in the northwest corner of the facility property on a utility easement. This area is physically separated from the former sludge incorporation area and would not be affected by runoff from the former sludge incorporation area. The remaining four exploratory borings were constructed in areas deemed representative of the designated field, approximately 100 to 200 feet from the associated well nest. The boreholes were abandoned upon conclusion of soil descriptive logging. Criteria used in the location of appropriate well nests and boring locations included: Where possible, well nests within the fields were constructed near areas of previous vegetative and small mammal sampling activities (see Section 3.4). J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-2 9 /1 6 /2 0 0 8  Boring locations were selected in areas deemed representative of the field conditions with no visible impact from surface water flow (i.e., erosion or sedimentation) or physical construction (i.e., road building or grading, or ditching). For the location of well nests outside of the former sludge incorporation areas, consideration was given to how the location would enhance groundwater monitoring capabilities for the entire sludge incorporation area. For example, certain wells were located along the outside margin of a specific field near the property boundary to provide soil and groundwater conditions at the property line (i.e., well location 130). A combination of air rotary and hollow stem auger drilling techniques were used for the construction of monitoring wells and soil borings. Following well completion, each well was developed to clear the well of particulate matter and allowed to remain undisturbed for approximately one week before sampling. The following subsections present an overview of the procedures used. 3.2.1.1 Bedrock Wells Drilling began with the bedrock wells to allow for logging and for installation of casing. Initial drilling, using a hollow stem auger rig, was continued until resistance to drilling was encountered. This depth was interpreted to represent the top of epikarst. Then drilling was continued with an air-rotary rig, carefully observing drilling characteristics to identify major weathered zones and to determine when competent rock was encountered. Once competent rock was identified, a socket was constructed approximately 6 to 10 feet into competent bedrock for insertion of the casing. The borehole was adequately cleaned, and 6-inch carbon steel casing was installed and grouted in place using a cement slurry mix. After grouting was completed, the casings were left undisturbed for a minimum of 24 hours to allow for adequate curing of the grout. 3.2.1.2 Epikarst Wells The data collected during the construction of the bedrock borings were used to designate completion depths for the epikarst wells. Epikarst well borings were constructed using air rotary drilling techniques with an 8-inch diameter, tri-cone rotary bit or percussion J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-3 9 /1 6 /2 0 0 8 hammer bit. The borings were extended to depths within the epikarst indicating the highest potential for groundwater communication as identified in the associated bedrock well borings. Drilling conditions were noted during construction and compared to that of the associated bedrock borings to evaluate consistency of rock and fracture zones. The borehole was adequately cleaned of cuttings and a 4-inch diameter stainless steel monitoring well was constructed with 10 feet of 0.01-inch slotted screen. A sandpack consisting of 20/40 sieve commercial grade filter sand was constructed to approximately 2 feet above the top of screen. This was followed by approximately 2 feet of bentonite chips and grout to the surface. 3.2.1.3 Residuum Wells Residuum wells and soil borings were constructed using hollow-stem auger drilling techniques. This allowed for the collection of in situ soil samples for logging and analysis purposes. Residuum well borings were constructed using 6-inch inner diameter augers to the depth designated in the initial boring as top of epikarst or until resistance to drilling was encountered. Upon completion of the borehole, a 4-inch diameter stainless steel well was inserted with 10 feet of 0.01-inch slotted screen. Well construction occurred within the augers to prevent collapse of the boring during construction. A sandpack, consisting of a 20/40 sieve commercial grade filter sand, was constructed to approximately 2 feet above the top of screen. This was followed by approximately 2 feet of bentonite chips and cement grout to the surface. 3.2.1.4 Exploratory Soil Borings Exploratory soil borings were constructed using 2.5-inch inner diameter augers. The borings were constructed to the water table for logging purposes and to collect soil samples for analytical testing. After completion, the boreholes were abandoned by filling with cement grout using tremie pipe pumping techniques. All monitoring well and boring locations were surveyed for horizontal and vertical control.

Residuum well 137R in Field 14 was dry and therefore was not sampled. Prior to sampling, static water levels and well depths were recorded to calculate the volumes for each of the wells. Wells were purged of liquid using either a 2-inch Grundfos pump or a 4-inch Grundfos pump depending on the well diameter and anticipated volume required for removal. The purge water was contained during the purging process and transported to the facility wastewater treatment plant for disposal. During the purging process, groundwater parameters, including pH, specific conductance, and temperature were continually monitored to ensure that the purging process was adequate. Purging continued until three well volumes were removed and the monitored parameters had stabilized, or until the well was pumped dry. A copy of the groundwater purge forms is provided in Appendix B. Following purging, the wells were allowed to recharge sufficiently to allow adequate sampling of the wells. Sampling was conducted within 24 hours of the purging of each well. Samples were collected from the monitoring wells using a polyethylene bailer, transferred to laboratory-prepared containers and shipped to the laboratories for sulfonate and TSS/TDS analyses. 3.2.3 Sampling of Existing Monitoring Wells Sampling of eight existing on-site monitoring wells (220R, 220L, 226R, 226L, 310R, 317L, 320L and 327R) was conducted in June and November of 2005 and 2006. The locations of the wells are shown in Figure 3-2. This group of pre-existing wells was selected based on a pre-existing agreement with the EPA. Water levels were recorded from each well location in order to calculate purge well volumes. Each well was purged for a minimum of three well volumes or until the well was pumped dry. Groundwater parameters, including pH, specific conductance, and temperature, were monitored during the purging process to ensure that the removal was adequate to allow appropriate sampling of the local groundwater system. Following J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-5 9 /1 6 /2 0 0 8 purging, the wells were allowed to recharge sufficiently to allow adequate sampling of the wells. Sampling was conducted within 24 hours of purging each well. Samples were collected from the monitoring wells using a polyethylene bailer, transferred to laboratoryprepared containers, and shipped to the laboratory for sulfonate analyses. 3.2.4 Water Levels Measurements for the Hydrogeologic Evaluation of the Former Sludge Incorporation Area In order to perform a hydrogeologic evaluation of the former sludge incorporation area, groundwater levels were recorded from the newly constructed wells (well sets 130 through 137) on January 5, 2005; April 11, 2005; and June 15, 2005. Groundwater elevations from monitoring wells previously installed in the former sludge incorporation area were also recorded on April 11, 2005 and June 15, 2005 to provide additional data. The water level elevations were used to evaluate each of the groundwater zones (i.e., residuum, epikarst and bedrock) and to select locations for off-site groundwater monitoring wells (see Section 3.7.1). Figures 2-6, 2-7 and 2-8 represent the most recent (February 2007) groundwater elevations for the residuum, epikarst and bedrock zones, which are consistent with earlier measurements. 3.3 SOIL SAMPLING 3.3.1 Initial Former Sludge Incorporation Area Sampling 3.3.1.1 Soil Borings From October through December 2004, samples were collected from soil borings during installation of the residuum wells (130R through 137R) in the former sludge incorporation area. The samples were collected using split-barrel soil samplers. The locations of the soil borings are shown in Figure 3-3. Discrete soil samples were collected from each of the soil borings at the following depths below ground surface (bgs): 0 to 3 inches 6 to 12 inches J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-6 9 /1 6 /2 0 0 8  1 to 1.5 feet 2 to 2.5 feet 5 to 5.5 feet At water table or boring refusal Composite soil samples also were collected in 5-foot intervals to boring refusal from four residuum soil borings: 131R (Field 9), 133R (Field 6), 134R (Field 8b) and 137R (Field 14). These composite samples were collected to provide a full sulfonate concentration profile so that all zones would be sampled if the above-mentioned discrete sampling did not include a zone where a higher concentration of sulfonates was present. As noted in Section 3.2.1, four exploratory soil borings (131B in Field 9, 133B in Field 6, 134B in Field 8b and 136B in Field 14) also were sampled down to the water table for the purpose of obtaining soil profiles and logs of soil conditions. In January 2005, an exploratory boring (SB-001B) was constructed in the northwest portion of the facility property to provide background data for the site. As noted previously, this northwest background area was selected as a reference location because it was never developed and is physically separated from the former sludge incorporation area. The exploratory soil borings were sampled at the discrete intervals described previously for the residuum well borings. At the exploratory soil boring located in the northwest background area, a composite sample (SBC-001B) also was collected every 5 feet to the water table. Due to the number of samples within the upper 3 feet of soil, it was necessary to collect the samples using a 4-inch stainless steel bucket auger. This allowed for collection of an adequate volume of soil from each sample interval to satisfy the sampling requirements. Following collection of the samples for depths 0 to 3 inches, 6 to 12 inches, 1.0 to 1.5 feet, and 2.0 to 2.5 feet, the auger rig was positioned over the location and the borehole was advanced to groundwater, collecting the remaining samples. Soil from specific sampling intervals was placed immediately into laboratory-prepared sample containers. Composite samples from each 5-foot drilling interval were placed into stainless steel containers and kept covered with polyethylene sheeting until the entire interval was collected. The collected media was blended until homogenous, and J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-7 9 /1 6 /2 0 0 8 appropriate volumes were collected in laboratory-prepared containers for analytical testing. Soil samples were submitted to the laboratories for sulfonate, TOC and grain size analyses. 3.3.1.2 Surface Soil In January 2005, surface soil samples were collected from five locations (SS-0001 through SS-0005) in each of the four fields (Field 6, Field 8b, Field 9 and Field 14) and three locations (SS-0001 through SS-0003) in the northwest background area to characterize surface soil conditions. The locations of the surface soil samples are shown in Figure 3-3. Samples were collected from the 0 to 3 inch bgs interval and the 3 to 6 inch bgs interval. Samples were collected using decontaminated stainless steel scoops. The sample area was cleared of surface vegetation and humus matter until mineral soils were encountered. A hole, approximately 6 inches in diameter and 3 inches deep, was constructed using the clean stainless steel scoop. The material was placed into a clean stainless steel mixing bowl, blended until homogenous, and appropriate samples were collected. The hole was advanced to a depth of 6 inches and cleaned of all loose material. Using a clean stainless steel scoop, soil was collected from the 3 to 6-inch interval and placed into a clean stainless steel bowl. Similarly, the soil was blended and appropriate samples were collected. Visual descriptions of the soil were made including color, texture and the visible presence of sludge residue. After sampling, the holes were backfilled with the remaining soil and appropriately identified for surveying. The soil samples were shipped to the laboratories for sulfonate, TOC and grain size analyses. 3.3.2 Additional Former Sludge Incorporation Area Sampling Additional soil sampling activities were performed in February and March 2006 to more fully characterize sulfonates concentrations throughout the former sludge incorporation area. These activities focused on surface and subsurface soils in the former sludge incorporation area Fields 5, 10, 11, 12 and 13, which were not sampled in the initial J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-8 9 /1 6 /2 0 0 8 characterization in 2004 and 2005, as well as in right-of-way areas adjacent to Field 9. The soil sampling locations are shown in Figure 3-4. Sampling in the former sludge incorporation area consisted of the collection of surface soil samples from the 0 to 3 inch and 3 to 6 inch bgs intervals at five locations (SS01 through SS05) within each of Fields 5, 10, 11, 12 and 13. The five surface soil sampling locations in each field were distributed throughout each of the fields. The surface soil sampling intervals were consistent with the initial characterization sampling protocol for Fields 6, 8b, 9 and 14 that were previously sampled. Direct push soil borings also were advanced at four locations within each of the fields with soil samples collected at the following depth bgs intervals: 0 to 3 inches 6 to 12 inches 1 to 1.5 feet 2 to 2.5 feet 5.0 to 6.0 feet These subsurface sampling intervals were consistent with initial characterization protocol with the exception that composite sampling of the boring cores over 5-foot intervals was not conducted and sampling depths were limited to 6 ft bgs. The four soil boring locations (GP01 through GP04) within each field were positioned with two soil borings located in the central portion of the field, one boring located adjacent to the downslope perimeter of the field but within the likely area of former sludge incorporation, and one boring located in the field based on site conditions. Shallow soil sampling was conducted at four right-of-way locations (SS-0010 through SS-0013) along the northern boundary of Field 9. These samples were collected at the 0 to 3 inch, 3 to 6 inch and 1 to 1.5 foot depth intervals, in a right-of-way area along the Norfolk Southern Railroad and an underground gas line. Shallow soil samples were also collected from four locations (SS-0006 through SS-0009) just outside the western border of Field 9, adjacent to the Finley Island Road right-of-way. The shallow soil samples J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-9 9 /1 6 /2 0 0 8 were collected at the 0 to 3 inch, 3 to 6 inch and 1 to 1.5 foot depth intervals. All surface and subsurface soil samples were placed in laboratory-prepared containers. Soil samples were submitted to the laboratories for sulfonate, TOC and grain size analyses. 3.3.3 Soil Borings Near Existing Monitoring Wells Eight existing monitoring wells (220L, 220R, 226L, 226R, 310R, 317L, 320L and 327R) at the 3M Decatur facility have been sampled for sulfonates on a semiannual basis. An exploratory soil boring was constructed in January 2005 in the vicinity of each well to collect surface and subsurface samples for logging and analysis. The locations of the eight wells are shown in Figure 3-2. The soil borings were constructed using 3-inch inner diameter hollow stem augers. Soil samples were collected continuously from each boring using split-barrel soil samplers to record geologic data and to provide media for analytical testing. Soil samples were collected from the 0 to 3 inch, 6 to 12 inch, 2.0 to 2.5 foot, 5 to 6 foot bgs intervals, and at the depth of the local water table. The soil boring construction details are summarized in Table 3-4. Following completion of the borings, the augers were removed and the borings were abandoned using a cement grout slurry and tremie pipe pumping techniques. The soil boring locations were surveyed for horizontal and vertical control. The soil samples were placed in laboratory-prepared containers and shipped to the laboratories for sulfonate, TOC and grain size analyses. 3.4 ON-SITE TERRESTRIAL BIOTA ACTIVITIES 3.4.1 Surveys Vegetation and small mammal surveys were performed at the 3M Decatur, Alabama facility from July 26 through July 29, 2004 in the former sludge incorporation area Fields 6, 8 and 9. Field 14, which did not receive sludge, was used as a control field and was also surveyed. The objective of this work was to conduct an initial survey to identify the J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-10 9 /1 6 /2 0 0 8 vegetation and small mammal communities present in the subject fields and develop the information necessary to select the target vegetation and small mammal species for the sampling program. Photographs of the vegetation in the fields are provided in Appendix C.1. A listing of observations of other fauna present in the fields and adjacent habitat during the period of the survey is presented in Appendix C.2. 3.4.1.1 Vegetation Survey The following is a summary of the results of a vegetation community survey in selected fields in the former sludge incorporation area at the 3M Decatur, Alabama facility. The survey specifically focused on those fields in which a concurrent small mammal survey was conducted (see Section 3.4.1.2); namely, Fields 6, 9, 8b and 14 (a control field on which no sludge was applied) (see Figure 3-5). Vegetation in the vicinity of each of the trapline locations was evaluated in each of the areas. In addition, sightings of various fauna observed during the period of the survey in the vicinity of the former sludge incorporation area were recorded (Appendix C.2). The objectives of the vegetation survey were to identify dominant plant species occurring in each of the investigation areas for evaluations of the vegetative communities and the animal communities they support and to provide information for the selection of target plant species to be sampled. In conducting the surveys, it became apparent that many of the fields supported heterogeneous plant communities varying along topographic changes in the landscape or the presence of plant species that develop isolated populations or "patches." To develop a representative community distribution, population breakdowns were conducted for specific areas within the field and cumulatively across the entire area of each of the fields under investigation. Vegetation was identified to the lowest possible taxon and, in most cases, plants were identified to species. In other cases, the plants were identified to genus either due to a mixed occurrence of several allied species, such as with the goldenrods (Solidago spp.) and/or due to the absence of plant features (such as inflorescence) to allow definitive species identification in the field. With most old field plant communities, dominant J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-11 9 /1 6 /2 0 0 8 species generally change seasonally during the year. This was apparent in most areas evaluated in that some species had gone to seed and were declining while others were beginning to emerge. As a result, the community breakdowns are representative of the vegetation occurring during the mid-summer period. The occurrence of species is presented as a percent of the total plant community based on visual estimates. Point counts or other statistical methods for determining plant distribution were not conducted as part of this survey. Dominant species were determined using the 50/20 rule. Ranking the areal coverage of each species in descending order of occurrence, those species with a cumulative sum exceeding 50 percent are considered dominant in the community. Additional species with an occurrence of 20 percent or greater are also considered dominant species in the community. Dominant plants are indicated in the tables for each area. Field 6 - Field 6 is located immediately south of the Norfolk Southern railway tracks in the northeast portion of the former sludge incorporation area. Figure 3-5 presents the general boundaries for each of the former sludge incorporation area fields. Field 6 is associated with a topographic high that slopes to the east, south and west. The primary flow direction for stormwater runoff is south turning southwest into Fields 9 and 10. Field 6 is occupied predominantly by herbaceous plants to shrubs with an occasional occurrence of small trees. The specific vegetative community varies across Field 6 depending on the topographic setting. The higher elevations are dominated by grasses and, at lower elevations, the grasses are gradually replaced with herbaceous plants. Localized variations were also observed due to isolated patches of certain species, such as sedge (Cyperus spp) and wild plum (Prunus americana), which tend to form patches or thickets. Photographs 1 through 3 in Appendix C.1 show the vegetation in Field 6. Compared to other fields in the vicinity, Field 6 appears to be in a later successional phase with occasional trees, including black cherry (Prunus serotina), sycamore (Platanus occidentalis) and wild plum (Prunus americana). The black cherry and sycamore were observed as isolated trees with a height between 10 and 20 feet. The wild J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-12 9 /1 6 /2 0 0 8 plum was observed forming isolated thickets with an estimated height of approximately 10 feet. The remainder of the field was vegetated with grasses and dicotyledonous herbs. A trapline was established within the field to monitor the small mammal community. The trapline location is presented in Figure 3-5. Tables 3-5 through 3-7 contain population breakdowns for specific intervals along the trapline established for the field. The changes in the community reflect changes in topography across the trapline. Station 7 (S7) of the trapline was established near Field 9 and reflects a significantly different vegetative community. Field 8b - Field 8b is located immediately west of Nebo Road as a central field in the former sludge incorporation area. Vegetation associated with this field is similar to that of the east side of Field 9 in that it is distinct from other fields in the area. A trapline was established immediately below the southern margin of Field 8b southeast of monitoring well 122C to evaluate the small mammal community. The trapline location is presented in Figure 3-5. Reconnaissance of the field indicated a relatively uniform vegetative community. As with most fields, there is a thick mat of senescent fescue grass as a cover. However, in contrast with other fields in the area, these mats are largely barren of other flora with the exception of isolated thickets of pokeweed (Phytolacca americana) approximately 6 feet in height and dock (Rumex crispus) as shown in Photograph 5, Appendix C.1. The remaining vegetation is restricted to low ground cover and sporadic herbaceous plants. A breakdown of the community is presented in Table 3-8. Photographs 4 and 5 in Appendix C.1 show the vegetation in Field 8b. Field South of Field 8b - This unnumbered field is located immediately west of Nebo Road and immediately north of Highway 20/72. Previous maps of the sludge incorporation fields did not identify this area, and it is not known if sludge was incorporated in this area. Initially, a trapline was established in the field under the assumption that it was part of Field 8b. Upon further evaluation, it was determined that J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-13 9 /1 6 /2 0 0 8 this field was not part of 8b and the trapline was moved farther north for the survey of Field 8b and is shown in Figure 3-5. This field occupies somewhat lower elevations than similar fields to the north and west. The area may be described as having a gentle grade with broad swales with moderate drainage. Vegetation is thick and consists predominantly of herbaceous plants with lesser amounts of grasses and shrubs. Eastern cottonwood (Populus deltoides) saplings were also identified as part of the community. A breakdown of the vegetative community is provided in Table 3-9. Photograph 6 in Appendix C.1 shows the vegetation in the field south of Field 8b and is shown in Figure 3-5. Field 9 - This field is located immediately east of Finley Island Road and south of the Norfolk Southern rail line (Figure 3-5). The field varies significantly in vegetation from west to east. The trapline was established in the west part of the field which exhibited similar vegetation to that of other fields evaluated. The trapline location is indicated in Figure 3-5. The trapline area slopes gently to the south and southwest, and is dominated by grasses and herbaceous plants. Shrubs such as winged sumac (Rhus copallina) also occur in isolated thickets. Herbaceous species also develop patches excluding other plants and forming a patchwork community. Across the area of the trapline, two general plant communities were observed. In the lower elevations (trapline stations S1 through S5), vegetation is predominantly herbaceous. Proceeding into higher elevations (trapline stations S6 through S7), grasses become dominant. Community breakdowns for each of these areas and a cumulative area distribution for Field 9 as a whole are presented in Tables 3-10 through 3-12. Photographs 7 and 8 in Appendix C.1 show the vegetation in Field 9. The east side of Field 9 exhibits a substantially different vegetative community similar to that of Field 8b (see Table 3-8). Field 14 - This field is located in the southwest corner of the property. It is bounded by Highway 20/72 on the south and Finley Island Road on the west. Initially, a trapline was established in the northern portion of the field extending to the northeast from monitoring J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-14 9 /1 6 /2 0 0 8 well 120C. Due to low trapping success, the line was moved to the southern portion of the field. The trapline is indicated in Figure 3-5. Field 14 consists of a mix of grasses and herbaceous plants typical of old field succession. Elevations vary across the field from well-drained gentle ridges to broad swales. Plant distribution was observed to vary according to the elevation (or drainage profile) in the area. Photographs 9 and 10 in Appendix C.1 show the vegetation in Field 14. The plant distribution for this area is presented in Tables 3-13 and 3-14. Discussion - Vegetative communities in the former sludge incorporation area fields consist of a mixture of planted and native flora. Grasses such as fescue and Bermuda grass were locally common but are gradually being replaced by typical old field vegetation. Local variation in plant species within and between the fields surveyed is evident, and patches of shrubs and vines such as wild plum, blackberry and passionflower are common. Periodic mowing of the fields has limited the establishment of typical pioneering woody species, and the overall area is dominated by forbs with localized patches of grasses and sedges. 3.4.1.2 Small Mammal Survey Methods and Sampling Locations - The small mammal survey was performed from July 26 through July 29, 2004 in the former sludge incorporation area Fields 6, 8, and 9. Field 14, on which no sludge was applied, was used as a control field and was also surveyed. Prior to the small mammal survey, scientific collection permit (SCP) 2870 was obtained from the Alabama Department of Conservation and Natural Resources (DCNR) and appropriate advance notification of the survey dates was provided to DCNR. In each of the fields, Sherman live box traps were set along a 300-foot trapline with paired traps (two each) at seven stations (designated S1 to S7) located at 50-foot intervals. Traps contained peanut butter and rolled oats as bait for small mammals likely to be present. Carrot slices were added to provide hydration for trapped animals. Trap placement at each of the stations was selected on the basis of visual observations of small mammal J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-15 9 /1 6 /2 0 0 8 runways and nest areas, where present. Because of the focused nature of the investigation, the trapping method and locations were selected to maximize the likelihood of capturing herbivorous/omnivorous small mammals suitable for the purpose of the monitoring program. Trapping commenced on the afternoon of 26 July 2004 with traplines in Fields 6, 8 and 14. The trapline in Field 9 was set on the following morning. Except for a daytime set on July 27, 2004 when overcast conditions and moderate temperatures permitted it, traps were deployed overnight with late afternoon sets and early morning tending and collection to protect captured animals from heat stress and dehydration. An overnight set of an individual trap is defined as a trapnight. Trapping continued until the morning of July 29, 2004. Two traplines were relocated for the July 28/29 trapnight. The initial trapline in Field 8 was relocated to the north when it was determined that the initial location was below the southern boundary of Field 8b based on updated mapping of the Field 8 boundaries. The subsequent trapline location, which is along the southern border of Field 8b, contains a vegetative community that is believed to be representative of conditions in Field 8b as a whole. The trapline at Field 14 was relocated to increase trapping success. The final trapline locations are shown in Figure 3-5. Captured mammals were identified using the appropriate taxonomic keys (Mirarchi, 2004, Whitaker and Hamilton, 1996; Whitaker, 1980; and Burt and Grossenheider, 1980). Initial specimens were measured for body and tail length and released. Lengths for subsequent specimens were estimated to minimize handling stress and provide more prompt release. While a sugar solution was available to rehydrate stressed specimens, dehydration symptoms were not evident and captured mammals were released with a minimum of handling. In addition to Sherman live traps, pitfall traps were also set to evaluate the potential occurrence of smaller mammals like moles and shrews. However, no mammals were captured in the pitfall traps. Small Mammal Survey Results - Table 3-15 contains a summary of the small mammal trapping results for a total of 152 trapnights. A total of 55 hispid cotton rats (Sigmodon hispidus) and 1 white-footed mouse (Peromyscus leucopus) were captured and released J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-16 9 /1 6 /2 0 0 8 during the survey. Of this total, 6 hispid cotton rats were collected during the July 27 daytime set. On the basis of trapnights only, a total of 49 hispid cotton rats were collected for a mean hispid cotton rat capture index of 0.322. Although mark and recapture techniques were not employed to estimate population, it appears that Field 6 contained the largest population of cotton rats in the areas surveyed (0.595 capture index). Conversely, the lowest density appeared to be in Field 14 (0.095 capture index). Trapping success in Fields 8 and 9 was intermediate with the Field 9 capture index of 0.357, somewhat higher than the Field 8 capture index of 0.250. All of the captured mammals appeared to be in good condition with smooth pelage. No visual evidence of deformities, lesions or tumors was noted. Several of the hispid cotton rats had visibly shortened tails that had healed prior to capture. Discussion - The hispid cotton rat (Sigmodon hispidus) is clearly the dominant small mammal species in the overgrown, herbaceous open fields. This finding is consistent with literature records of hispid cotton rat habitat preferences and small mammal community characteristics in the South in general (Whitaker and Hamilton, 1998), and in Alabama, in particular (Mirarchi, 2004). Although the 3M Decatur facility is near a southern lobe of the distribution of the meadow vole (Microtus pennsylvanicus) that extends into Alabama, the hispid cotton rat, which occupies a somewhat similar niche to the vole, replaces the meadow vole in much of the South (Whitaker and Hamilton, 1998). Members of the suborder Myomorpha, Sigmodon (and microtines such as M. pennsylvanicus), while descended from primarily seed-eating ancestors, are primarily grass eaters characterized by the construction of runways created by clipping vegetation and frequency of use (Baker, 1971). The ecology of the hispid cotton rat has been studied in a variety of the habitats located within the geographic range of the species and includes a substantial body of studies from the coastal plains in Texas and the prairies of Oklahoma and Kansas. Hispid cotton rat population densities are prone to significant oscillations on an annual basis characterized by low points in the spring and high points in the fall in the southeast (Odum, 1955). Climatic extremes such as unusually cold winters and drought conditions have been J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-17 9 /1 6 /2 0 0 8 shown to affect population densities and suppress autumnal population increases (Langley and Shure, 1988; Goertz, 1964). Predation pressure, especially in conjunction with reduction or cessation of reproduction in fall and winter and reductions in available cover, has been suggested to act as a limiting factor more likely to regulate Sigmodon populations than food availability or inclement weather (Schnell, 1968). Home ranges of 0.25 to 0.99 acre (0.2 to 0.4 hectare [ha]) are typical for the hispid cotton rat with males at the higher end of the range and with somewhat lower and exclusive home ranges for established females (Whitaker and Hamilton, 1998). Based on radiotelemetry data on a Texas coastal plain population, the exclusivity of home range (41 percent for males and 34 percent for females) indicated a high degree of intolerance and home ranges varied based on the sex of the individual and seasonality (Cameron and Spencer, 1985). Population densities, as noted above, vary seasonally and, in a review of data from 17 field studies in a variety of habitats and locales, Cameron and McClure (1988) reported an average minimum density of 13 per acre and an average maximum density of 77 per acre. Hispid cotton rats are highly prolific due to their short gestation period of approximately 27 days, high litter sizes, and very rapid maturation (Whitaker and Hamilton, 1998). Individuals are generally short-lived with average survival of approximately 6 months in the wild (Odum, 1955). Some hispid cotton rats survive for 10 months to a year (Goertz, 1964). Omnivorous and frequently a significant agricultural pest, the hispid cotton rat prefers grassy plants, although insects and eggs and chicks of ground-nesting birds supplement their diet (Whitaker and Hamilton, 1998; Whitaker, 1980). Based on the analysis of stomach contents, Fleharty and Olson (1969) determined that monocots (e.g., grasses) constituted the majority of the hispid cotton rat diet with lesser quantities of dicots (e.g., forbs) consumed. Furthermore, they concluded that the dominance of vegetation (availability) was not the primary factor influencing the diet and that less dominant species were frequently selected (Fleharty and Olson, 1969). Additional studies have demonstrated the distinct dietary preference for monocots via examination of fecal pellets or feeding trials (Kincaid and Cameron, 1982a; Kincaid and Cameron, 1982b; Kincaid J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-18 9 /1 6 /2 0 0 8 and Cameron, 1985; Randolph et al., 1991; and McMurray et al., 1994). Cameron and Eshelman (1996) concluded that the hispid cotton rats need to ingest some quantity of dicots to meet nutritional requirements for proteins necessary for growth and reproduction. Insect consumption by the hispid cotton rat is low and has been suggested to be incidental ingestion of sedentary insects on plants during foraging and ectoparasites from grooming activities (Kincaid and Cameron, 1982b). A bibliography of references that were reviewed regarding hispid cotton rat dietary preference is provided in Appendix C.3. A wide range of vertebrate predators including hawks, owls, foxes, coyotes, bobcats and many snakes are known to prey on the hispid cotton rat. 3.4.2 Sampling Based on the dominance of hispid cotton rats in the small mammal community in the former sludge incorporation area fields as determined by the findings of the vegetation and small mammal surveys and their diet of primarily grasses and forbs, the hispid cotton rat is considered to be the appropriate target species for the sulfonate assessment program. The hispid cotton rat has been the subject of numerous ecological studies at other locations, and a robust literature exists on the dietary preferences, nutrition and foraging strategies based on both laboratory and field research with this species. Prior to performing sampling of the hispid cotton rat population and vegetation in former sludge incorporation area Fields 6, 8, 9 and 14, a literature search was performed to identify prospective vegetation species or genera potentially present or represented by related species at the Decatur site. A list of literature reviewed is provided in the bibliography at the end of this section. Dietary preferences documented in the literature were compared with the vegetation survey results to assist in the selection of three plant species to be sampled concurrently with the hispid cotton rats and are summarized in Table 3-16. To the extent that conditions permitted, each of the target vegetation species were common species present among two or more of the individual fields to be sampled and are likely components of the hispid cotton rat diet based on the scientific literature. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-19 9 /1 6 /2 0 0 8 Hispid cotton rats have been demonstrated to distinctly prefer monocots with a lesser, though potentially necessary, nutritional reliance on dicots (Cameron and Eshelman, 1996; Eshelman and Cameron, 1996; and Kincaid and Cameron, 1982b). Furthermore, while seasonal shifts in diet occur in response to the changes in the vegetation community and the availability of preferred forage, vegetation consumption by hispid cotton rats includes many plant species that are not dominant (Fleharty and Olson, 1969). Consequently, the selection of the vegetation species to be sampled was based primarily on dietary preference rather than abundance (or dominance) of those species in the immediate vegetation community. The following sections provide a synopsis of the vegetation and small mammal sampling activities performed in October 2004. 3.4.2.1 Vegetation Sampling Vegetation sampling was performed concurrently with small mammal sampling on October 7, 2004. Table 3-17 contains a listing of vegetation samples collected by location. Samples were collected in the vicinity of the small mammal traplines and their locations flagged for location control. Selection of Species - Prior to collecting vegetation, a reconnaissance of the fields was performed to survey the presence/absence of vegetation and any significant shift in the plant community since the July 2004 vegetation survey. The results of the reconnaissance were compared with the compilation of taxa identified in the hispid cotton rat dietary preference literature to select the primary target species (Table 3-16). The three primary plant species selected for sampling were broomsedge (Andropogon virginicus), pokeweed (Phytolacca americana) and curly dock (Rumex crispus). All three species were present in Field 6, Field 9 and the northwest background location. Although both pokeweed and curly dock were present in Field 8, broomsedge was absent from Field 8 and present in only one of the two locations in Field 9. Curly dock was absent from Field 14. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-20 9 /1 6 /2 0 0 8 In addition to samples of the primary species, samples of secondary species were also collected of a common grass abundantly present in both Field 8 and Field 9, and goldenrod (Solidago spp.) from Fields 6, 9 and 14. The grass species was included due to the importance of monocots in hispid cotton rat diets. Similarly, Solidago species are also dietary components for the hispid cotton rat (Fleharty and Olson, 1969). Sample Site Selection - Once the species had been selected for sample collection, sample sites were identified in each of the fields designated for investigation. Two sample sites were selected in each field. The criteria used to select suitable sampling sites were as follows: The sites should be representative of the overall conditions of the field. The sampling sites should contain the species designated for sampling within a relatively close area (approximately 20 feet). One of the sampling sites in each field should be located proximate to previous/current animal trapline locations. One sampling site was also designated within a power line easement in the northwest portion of the facility designated as the northwest background area for the investigation. The sites selected for sampling are presented in Figure 3-6. Sampling Activities - Prior to sampling each site, individual plants were identified for sampling. Pin flags were placed at each plant to identify the locations. Where the plants were not large enough to provide the necessary sample volume, multiple plants from the same sample location were collected. An example of this includes the emerging grass in Fields 9 (east side) and 8b. In this case, several hundred plants within approximately two square feet were collected as a composite for submittal to the laboratory. Sampling was conducted by manually removing portions of each plant and placing them into appropriately labeled sample containers. Optimally, it was desired to collect entire plants (above ground portion) for submittal to the laboratory. However, due to the large size of some plants, those portions of plants more likely to be used as a food source by J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-21 9 /1 6 /2 0 0 8 the hispid cotton rat population were selected for sampling. This generally included the leaves, young shoots, flowers or seeds, and branch tips. Woody portions of the stems and large stems were generally excluded and the vegetation samples were not rinsed or washed. The samples were placed in containers which were then placed into cooled ice chests for transfer to a freezer. Once adequately frozen, the samples were packed with dry ice and submitted to Exygen for sulfonate analyses. A summary of the plant samples submitted to the laboratory is presented in Table 3-17. 3.4.2.2 Small Mammal Sampling Small mammal sampling was performed concurrently with vegetation sampling from October 5 through 7, 2004, under SCP No. 2870 issued by DCNR. Small mammal traplines were located in Fields 6, 8b, 9, 14 and the northwest background location (Figure 3-6). No small mammals were captured in the northwest background location trapline. The habitat in the northwest background location consists of a power line rightof-way with mowed grass to the tree lines on both sides of the corridor. Consequently, while all three of the primary vegetation species were present along the edge of the closely mowed corridor, insufficient cover in the majority of the area appears to preclude the establishment of a hispid cotton rat population. Sample Site Selection - Results of the July 2004 small mammal survey indicated that the hispid cotton rat is the dominant member of the old field small mammal community and that a high population density existed at the time of the survey. Consequently, sampling locations were selected in the immediate vicinity of the target vegetation sample locations to maximize correspondence of vegetation, soil and small mammal tissue analytical data (Figure 3-6). Multiple traplines of Sherman live traps baited with peanut butter and rolled oats were set in each field to establish a sampling grid surrounding the vegetation/soil sampling locations. With the exception of Field 8b, which required an extended trapline in order to obtain sufficient specimens, the sampling grids were approximately 50 by 50 meters.

Samples of serum and liver from the specimens were shipped to Exygen for sulfonate analyses. 3.5 SEDIMENT, SURFACE WATER AND POREWATER SAMPLING 3.5.1 Avenue A and Goose Pond 3.5.1.1 On-Site Surface Water and Sediment Sampling Sampling of sediment and surface water in the on-site Avenue A drainageway was performed in December of 2004 and 2006. Six sediment samples (designated DAA-SDLOC001 through -LOC006) were collected from locations in the Avenue A drainageway within the facility. The sampling locations in the Avenue A drainageway are shown in Figure 3-7. Sediment samples were collected, transferred to a stainless steel bowl, homogenized and placed in labeled sample bottles. The samples were submitted to the laboratories for sulfonate, TOC (2004 only), and grain size (2004 only) analyses. Surface water sampling was performed in conjunction with the sediment sampling. Surface water samples were collected at two locations (LOC002 and LOC005) in the Avenue A drainageway by submerging a pre-cleaned unlabeled polyethylene sample bottle below the surface, removing the cap, filling the sample bottle below the water surface and recapping under water. The contents of the sample bottle were transferred to a labeled sample bottle and the process repeated to fill the requisite number of sample bottles. Surface water sampling was performed prior to collection of sediment samples, and collection was performed from downstream locations to upstream locations. The surface water samples were submitted to the laboratories for sulfonate and TSS/TDS (2004 only) analyses. Field measurements of temperature, pH, dissolved oxygen (DO) and conductivity also were recorded. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-23 9 /1 6 /2 0 0 8 3.5.1.2 Additional On-Site Surface Water and Sediment Sampling In April 2006, three surface water samples (at locations OSP01, OSP02 and OSP03) and two sediment samples (at locations OSP01 and OSP02) were collected from the on-site pond (Goose Pond) and its influent stream, which are located at Finley Island Road and Avenue A. The locations of these samples are shown in Figure 3-8. The surface water samples were collected by submerging a precleaned, unlabeled polyethylene bottle below the surface, removing the cap, filling the sample bottle below the water surface and recapping under water. The contents of the sample bottle were transferred to a labeled sample bottle and the process repeated to fill the requisite number of sample bottles. The sediment samples were collected with a petite ponar sampler and were co-located with two of the surface water sampling locations. The surface water samples were submitted to the laboratories for sulfonate and TSS/TDS analyses. The sediment samples were submitted to the laboratories for sulfonate, TOC and grain size analyses. 3.5.2 Tennessee River / Bakers Creek 3.5.2.1 Surface Water and Sediment Sampling Initial sampling of sediment and surface water in the Tennessee River and Bakers Creek was performed in December 2004. A second sampling event at these locations occurred in December 2006. Sediment sampling in the Tennessee River and Bakers Creek was performed at six locations. The sediment samples were co-located with surface water sample locations and, in the Tennessee River and Bakers Creek, fish and clam sampling locations (see Section 3.6). Three of the sediment sampling locations are described as follows: upstream of the facility at river mile (RM) 307.5 (designated as DL3 in this study), across the river from the facility at RM 301 (designated as DL2 in this study), and downstream of the facility at the mouth of Fox Creek (approximately RM 296; designated as DL1 in this study). Additional locations that were sampled include a location farther downstream on the Tennessee River at the mouth of Mallard Creek at approximately RM 293 (approximately 8 miles downriver from the facility; designated DMC), the cove and mouth of Bakers J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-24 9 /1 6 /2 0 0 8 Creek in the vicinity of the 3M facility's wastewater treatment plant outfall (designated DOU), and Bakers Creek upstream of the facility's outfall (designated DBC). Three samples of sediments were collected at each of the locations for a total of 18 sediment samples collected from the Tennessee River and Bakers Creek. The locations of these samples are shown in Figure 3-7. Sediment samples were collected using a petite ponar dredge, transferred to a stainless steel bowl, homogenized, and transferred to labeled sample bottles. Samples were subsequently submitted to the laboratories for sulfonate, TOC (2004 only) and grain size (2004 only) analyses. Surface water sampling was performed in conjunction with both sediment sampling events. A single surface water sample was collected at each of the six sediment sampling locations in the Tennessee River and Bakers Creek. In addition, in 2004 only, a sample was collected from the river channel downstream of the Daikin wastewater treatment effluent outfall (designated DDO). Water samples from the Tennessee River and Bakers Creek locations were collected using a General Oceanics Model 1010 Niskin sampler. Samples were collected from the water column based on the water depth at the sampling locations. For those locations at which the depth was equal to or less than 10 feet, samples were collected at 0.6 of the total water depth. For locations greater than 10 feet, surface water samples were composited from samples from 0.2 and 0.8 of the total water depth. Surface water samples were collected prior to sediment sample collections at each sampling area. The surface water samples were submitted to the laboratories for sulfonate and TSS/TDS (2004 only) analyses. Field measurements of temperature, pH, DO and conductivity also were recorded. 3.5.2.2 Supplemental Surface Water Sampling Based on a review of the initial surface water analytical data for samples collected from the Tennessee River, supplemental sampling was conducted in the Tennessee River to increase the understanding of the presence of sulfonates in the river. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-25 9 /1 6 /2 0 0 8 The supplemental surface water sampling included a longitudinal series of samples along 53 miles of the river channel and three transects across the width of the river channel. The sampling locations are shown in Figure 3-9. The longitudinal series consisted of an upstream sample at RM 307 (adjacent to the 2004 DL3/2002 LOI-3 location); samples in Wheeler Lake at RM 301, RM 295, RM 289, RM 283, and RM 277; samples in Wilson Lake at RM 271, RM 265 and RM 261; and two samples below the Wilson Dam in Pickwick Lake at RM 256 and RM 254 in the vicinity of Florence and Sheffield, Alabama. Five duplicate samples were collected at a subset of the longitudinal series sampling locations (at RM 254, 261, 277, 289 and 301), which were field-filtered with a 0.45-micron filter. The filtered surface water samples were collected for comparison with unfiltered sample results to assess the fraction of sulfonates potentially adsorbed to suspended sediments in river water. The transect sampling was conducted at three locations near the 3M Decatur facility to investigate the spatial distribution of the sulfonate concentrations across the river channel. The transects were aligned perpendicular to flow and located in the vicinities of RM 301 (near the 3M facility), RM 299 (downstream of the 3M facility), and RM 287 (farther downstream of the facility). Each transect consisted of 10 equally-spaced sampling stations across the river. Flow measurements were recorded in addition to collection of surface water samples at each of the stations. Sample collection was performed using a Niskin bottle. For sample locations with water depths of 10 feet or less, a single sample was collected at 0.6 of the total water depth (i.e., 6 feet deep at a location with a 10-foot depth). At sampling locations greater than 10 feet in water depth, samples from the 0.2 and 0.8 depths were composited into one representative sample. The surface water samples were submitted to the laboratories for sulfonate and TSS/TDS analyses. 3.5.2.3 Porewater Sampling To assess the groundwater to surface water pathway in the Tennessee River on the northern shore of the plant, porewater/sediment/surface water sampling was conducted in J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-26 9 /1 6 /2 0 0 8 August 2005. Porewater is the water contained within the void spaces of the soil/sediment found at the bottom of the river bed and could be influenced by groundwater discharging into the river. During this sampling event, co-located porewater, surface water and sediment samples were collected for sulfonate analyses. The locations (STA001 through STA012) of these samples are shown in Figure 3-10. Collection of co-located porewater/surface water/sediment samples in the near-shore zone at the groundwater/surface water interface adjacent to the facility would provide data to address the groundwater to surface water pathway. Flow net analysis indicates that the distance into the Tennessee River from the facility's shoreline, which would receive the majority of affected groundwater from the Chemical Plant, is approximately 200 feet. Based on the flow net analysis, it is estimated that the maximum shoreline length of the groundwater plume discharge is 2,100 feet. This area was targeted for sampling using a 200-foot by 200-foot grid approach. As such, 40,000-square foot grid blocks were established. Twelve locations, one at the center of each grid block, were designated for porewater/sediment/surface water sampling along the shore of the Tennessee River (Wheeler Reservoir). Porewater was collected using 1-inch diameter stainless steel sampling probes. The probes were constructed with 0.5 foot of 0.005-inch slotted screen and sufficient stainless steel riser to extend above the water surface. In accordance with the porewater sampling Standard Operating Procedure (SOP), the probes were to be driven approximately 1 foot into the sediment so that the screen intercepted a depth of 0.5 to 1.0 foot below the top of the sediment. Installation was accomplished at most locations by pushing the probe directly into the sediment using hand pressure. At several locations, the surface sediment was insufficiently consolidated to support the weight of the sampling probe and the casing. At these locations, the probe was allowed to settle on its own weight and then pushed an additional 6 inches to access competent sediments for sample acquisition. Once in place, a buoy was attached to the riser to ensure relocation of the probe, and the probe was purged of fluids using a peristaltic pump to develop the station for sampling. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-27 9 /1 6 /2 0 0 8 All of the stations were purged to dryness. The total volume of fluids removed was recorded and the station was allowed to recharge. Water levels were monitored during recharge to evaluate the recharge rate for each location. Due to the fine-grained sediment encountered, recharge rates were extremely slow, ranging from less than 0.0001 to approximately 0.25 gpm. Stations 005 and 006 indicated recharge rates of 0.25 and 0.038 gpm, respectively. However, the distinct difference in recharge rates exhibited for the emplaced probes versus "open" recharge to the probes suggests that an adequate seal was achieved during probe installation and that the water collected is representative of the porewater system rather than the overlying water column. The probes were allowed to recharge sufficiently for sampling. Due to the slow recharge exhibited at some of the locations, sampling was accomplished through multiple extraction events and in some cases only partial samples were collected. Priority was given to aliquots for sulfonates analysis over TSS/TDS aliquots where porewater volumes were low. Surface water samples were also collected at each of the sampling locations to provide comparative data. The surface water samples were collected at 0.6 of the total depth to sediment at each station. Surface water samples were collected for sulfonate and TSS/TDS analyses. Water parameters, including temperature, specific conductivity, pH and dissolved oxygen, also were recorded. Sediment samples were collected at each of the designated sampling stations using a stainless steel petite ponar sampler. Each sample was placed into a plastic container and homogenized, and sufficient volumes were collected for analytical testing. The sediment samples were submitted to the laboratories for sulfonate, TOC and grain size analyses. In general, sediment within the area of investigation consisted of dark grayish-brown clay and silty clay. Asiatic clams (Corbiculafluminea) were observed to be locally abundant associated with Stations 004 through 006. The absence of gravel or sand lenses suggests that the stations are not influenced by wave action along the shore of Wheeler Reservoir. One exception was at Station 012 where sediment consisted of dark grayish-brown sandy J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-28 9 /1 6 /2 0 0 8 clay. The location is offshore from a stormwater discharge at the facility. A prominent alluvial fan consisting of sand and gravel occurs in the near shore area in association with the discharge point of the drainageway. 3.5.2.4 Additional Surface Water and Sediment Sampling Following the initial hydrogeologic evaluation of the former sludge incorporation area, additional off-site surface water and sediment sampling was conducted. The off-site sampling program included surface water and sediment sampling of the Bakers Creek drainage system to evaluate the potential impact of groundwater discharge into the drainage system, including Bakers Creek and its main tributary. Eleven surface water samples (at locations BPP01, BPP02, BPP03, BCT01, BCT02, BCT03, BC01, BC02, BC03, BC04 and BC05) and three sediment samples (at locations BPP01, BPP02 and BPP03) were collected in April 2006. Sample locations are shown in Figure 3-8. The surface water samples were collected by submerging a pre-cleaned, unlabeled polyethylene bottle below the surface, removing the cap, filling the sample bottle below the water surface and recapping under water. The surface water samples were transferred from the sampling container to laboratory-prepared containers. The sediment samples were collected with a stainless steel sediment coring device with polycarbonate liners and were co-located with three of the surface water sampling locations. The surface water samples were submitted to the laboratories for sulfonate and TDS/TSS analyses. The sediment samples were submitted to the laboratories for sulfonate and TOC analyses. 3.6 TENNESSEE RIVER AND BAKERS CREEK FISH AND CLAM SAMPLING 3.6.1 Fish Initial fish sampling under this program was performed at six locations (reaches) in the Tennessee River and Bakers Creek from October through December 2004. A second sampling round was performed in December 2006. Collections were performed in J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-29 9 /1 6 /2 0 0 8 accordance with the requirements of SCP No. 2870 issued by Alabama DCNR. The target species, largemouth bass (Micropterus salmoides) and channel catfish (Ictalurus punctatus), were present in all reaches (sampling locations) in the Tennessee River. The samples were collected from an upstream sampling area (DL3), a cross river sampling area (DL2), a Bakers Creek sampling area (DBC), a facility outfall cove sampling area (DOU), a Fox Creek sampling area (DL1) and a Mallard Creek sampling area (DMC). Sampling reaches are identified in Figure 3-11. Fish sampling methods included electrofishing and trotlining. Electrofishing was conducted using boat-mounted generator-powered Coffelt Mark XX and Smith-Root Model VI-A electrofishing units. All of the largemouth bass samples were collected by electrofishing. Only target species were dipnetted and retained as samples except for threadfin shad (Dorosoma petenense). Trotlines consisting of long, heavy cords with multiple baited hooks attached by sections of monofilament line were used for collecting the channel catfish. Hook sizes ranged from No. 8 to No. 2, and the trotline bait consisted of chicken livers in the initial sets followed by threadfin shad that were collected for trotline bait during electrofishing. Non-target species were released. In the 2004 sampling event, 10 samples of each species (largemouth bass and channel catfish) were collected at each of the six sampling reaches. Of these 10 samples per species, five were prepared for fillet tissue samples and five were prepared for whole body samples. Each fish retained for tissue analysis was weighed and total length was measured. Morphometric data for the individual samples are provided in Table 3-19. A total of 120 fish samples were collected during this sampling event. In the 2006 sampling event, 10 samples of each species (largemouth bass and channel catfish) were collected at five of the six sampling reaches. Of these 10 samples per species, five were prepared for fillet tissue samples and five were prepared for whole body samples. Only two largemouth bass samples were collected at reach DL2 and these were submitted for whole body analyses. No largemouth bass fillet analytical results were available for DL2 due to limited sample collection. Each fish retained for tissue analysis was weighed and total length was measured. Morphometric data for the individual J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-30 9 /1 6 /2 0 0 8 samples are provided in Table 3-20. A total of 112 fish samples were collected during the December 2006 sampling event. Fish samples were frozen and shipped on dry ice to the laboratories for subsequent sample preparation, sulfonate analyses, and shipment of subsamples of the tissue homogenate to STL for percent lipids determination. 3.6.2 Clams Asiatic clams (Corbiculafluminea) were collected in December 2004/2006 from each of six fish sampling reaches (Figure 3-11) by towing a weighted benthic dredge hung with 3/4-inch seine mesh to allow sediment to clear but retain clams. Three or more approximately 500-meter long tows were performed in each sampling reach. On retrieving the benthic dredge from a tow, clams were picked and transferred to a zip-lock bag, debris was culled, and the benthic dredge redeployed. Clams were rinsed with deionized water and enumerated, and the largest and smallest clams in each sample were measured. Table 3-21 lists the clam samples along with the associated morphometric data. The complete clam samples were frozen whole and shipped on dry ice to Exygen for subsequent sample preparation (including shucking and homogenizing), sulfonate analyses, and shipment of subsamples of the tissue homogenate to STL for percent lipids determination. 3.7 ADDITIONAL ASSESSMENTS 3.7.1 Off-Site Monitoring Well Installation and Sampling 3.7.1.1 Installation Following the initial hydrogeologic evaluation of the former sludge incorporation area, off-site monitoring well installation and sampling was conducted. This sampling program included the installation of five sets of nested wells at off-site locations potentially downgradient of the former sludge incorporation area to evaluate groundwater and soil conditions to the northwest, west, southwest, south and east of Bakers Creek. One set of nested wells was proposed along the eastern boundary of former sludge J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-31 9 /1 6 /2 0 0 8 incorporation Field 11 to provide data on the eastern flow component of the off-site groundwater flow from the former sludge incorporation fields. This set of wells is actually just inside the eastern property boundary of the site. After securing access agreements with off-site property owners, 17 monitoring wells were constructed from November 2005 through April 2006. Borings were logged by an experienced geologist noting color, texture, moisture content and any odors or discoloration. The monitoring well locations are shown in Figure 3-12. A summary of the soil boring and well construction data is presented in Tables 3-22 and 3-23, respectively. A copy of the boring logs and well completion logs is provided in Appendix A. As shown in Figure 3-12, wells 601R,S,L were installed to the northwest, wells 602R,S,L to the west, wells 603R,S,L to the southwest, wells 604R,S,L to the south, and wells 605R,L east of Bakers Creek. Wells 138R,S,L were installed along the eastern boundary of former sludge incorporation Field 11. With one exception, each cluster consisted of three wells: a residuum well, an epikarst well, and a bedrock well. The 605 well cluster was constructed with only a residuum well and bedrock well because a developed epikarst zone was not encountered. Epikarst and bedrock wells were constructed using air rotary drilling. The residuum wells were constructed using hollow-stem auger drilling techniques. Drilling began with the bedrock wells to allow for installation of casing. Drilling was advanced until resistant drilling (first rock) was encountered. This depth is interpreted to represent the top of epikarst. Drilling continued, carefully observing drilling characteristics to identify major weathered zones and to determine the lower extent of weathered bedrock. Once competent (unweathered) rock was identified, a socket was constructed approximately 8 to 10 feet into the competent bedrock to confirm that the boring was below the weathered zone and to install casing. The borehole was adequately cleaned, and 6-inch carbon steel casing was installed and grouted into place using a J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-32 9 /1 6 /2 0 0 8 cement slurry mix. After grouting was completed, the casing remained undisturbed for a minimum of 24 hours to allow adequate curing of the grout. Data collected during the construction of the casing sockets were used to establish completion depths for the associated epikarst monitoring wells. Epikarst well borings were constructed using air rotary drilling techniques with an 8-inch diameter tri-cone rotary bit or percussion hammer bit. The borings were extended to a depth within the epikarst indicating a high potential for groundwater communication. Drilling conditions were noted during construction and compared to that of the associated bedrock boring to evaluate consistency of rock and fracture zones. The borehole was adequately cleaned of cuttings and a 4-inch diameter stainless steel monitoring well was constructed with 10 feet of 0.01-inch slotted screen. A sandpack consisting of 20/40 sieve commercial grade filter sand was constructed to approximately 2 feet above the top of screen. This was followed by approximately two feet of bentonite chips and grout to the surface. Residuum wells were constructed using hollow-stem auger drilling techniques. This allowed for the collection of soil samples for logging and sampling purposes. Residuum well borings were constructed using 4-inch inner diameter augers to the depth designated in the initial boring as top of epikarst or until resistant drilling was encountered. Upon completion of the borehole, a 2-inch diameter stainless steel well was inserted with 10 feet of 0.01-inch slotted screen. Well construction occurred within the augers to prevent collapse of the boring during construction. A sandpack, consisting of a 20/40 sieve commercial grade filter sand, was constructed to approximately 1 to 2 feet above the top of the screen. This was followed by approximately 2 feet of bentonite chips and cement grout to the surface. Once installed, the monitoring wells were completed at the surface with lockable protective covers and concrete pads. Wells constructed at site 605 were completed with flush-mount covers within a single concrete pad.

Sampling depths were selected to provide data on vertical distribution of sulfonates and included 0 to 3 inches, 6 to 12 inches, 1.0 to 1.5 feet, 5.0 to 5.5 feet and 10.0 to 11.0 feet bgs. Soil from specific sampling intervals was placed into disposable plastic trays and blended. The soil was then placed into laboratory-prepared sample containers and shipped to the laboratories for sulfonate, TOC and grain size analyses. 3.7.1.3 Groundwater Sampling Following well completion, each well was developed to clear the wells of particulate matter. The first round of groundwater sampling at these wells took place in April 2006. Wells 604L and 604S were sampled again in December 2006. Well clusters 601 through 605 were resampled in September 2007. Wells 605R and 605L were sampled again in April 2008. Prior to sampling, static water levels and well depths were recorded to calculate the volumes for each well. Wells were purged of water using either a 2-inch Grundfos pump or a 4-inch Grundfos pump, depending on the well diameter and anticipated volume of water required for removal. The purge water was contained and transported to the 3M facility wastewater treatment plant for treatment. During the purging process, groundwater parameters, including pH, specific conductance and temperature, were continually monitored to ensure that the purging process was adequate. Purging continued until three well volumes were removed and the monitored parameters had stabilized, or until the well was pumped dry. A copy of the groundwater purge forms is provided in Appendix B. Following purging, the wells were allowed to recharge sufficiently to accommodate sampling of the wells. Sampling was conducted within 24 hours of the purging of each well. Samples were collected from the monitoring wells using a polyethylene bailer, transferred to laboratory-prepared containers and shipped to the laboratories for sulfonate and TSS/TDS (April 2006 only) analyses. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-34 9 /1 6 /2 0 0 8 3.7.2 Off-Site Residential Well Sampling Two residential wells were identified on neighboring properties southwest and south of the Decatur facility. The residential well locations are shown in Figure 3-12. On November 17, 2006, the two residential wells were sampled. Property No. 1 is located immediately south of the 3M Decatur facility and Highway 72. The pump house on the property is located adjacent to the house in a small wooden pump enclosure. The sample was collected from a hose spigot approximately 25 feet from the well. This was the closest point of sampling to the well. The spigot was turned on and allowed to flow for a minimum of 10 minutes while monitoring the following water quality parameters: temperature, pH, specific conductance and dissolved oxygen. Once the parameters had stabilized, the flow at the spigot was reduced and samples were collected. The well/sample location is identified as RESW01. The sample data and water quality parameters were recorded onto a sampling data sheet. A copy of the sampling data sheet is provided in Appendix B. Property No. 2 consists of two residences supported by the one well. The property is located north of Highway 72 southwest of the 3M Decatur facility. The well is located in a stone pump house located between the two homes. The well was purged a minimum of 10 minutes following the procedures previously described. The sample was collected directly from a spigot located at the well. The well/sample location is identified as RESW02. The sample data and water quality parameters were recorded onto a sampling data sheet. A copy of the sampling data sheet is provided in Appendix B. The two wells have been abandoned and the residences connected to the public water (Decatur Utilities). During well abandonment activities, it was found that there was another well located near RESW01 (see Figure 3-12). However, this well had not been used for some time and it was also abandoned. 3.7.3 Potable Water Treatment Plants Finished and raw (untreated) water samples were collected from six public water treatment plants (WTPs) in February, April, May, June, October and December 2005. J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-35 9 /1 6 /2 0 0 8 The samples were collected from Decatur Utilities, West Morgan/East Lawrence, Muscle Shoals, Florence, Tennessee Valley Authority, and Sheffield WTPs, which have intakes on the Tennessee River. The following subsections describe the details of the water sampling activities. 3.7.3.1 City of Decatur WTP Samples of the Decatur Utilities public water supply were collected on 10 February 2005 with the assistance of the Decatur Utilities staff. Representatives of Southern Environmental Testing Inc., Florence, Alabama (consultant to Decatur Utilities) and P.E. Lamoreaux & Associates, Tuscaloosa, Alabama (consultant to other interested parties) also collected water supply system samples at the same locations. Samples of finished water (post-treatment potable water) were collected at four locations within the distribution system in Decatur, Alabama. Each of the finished water sample locations were permanent sampling points tied into the potable water mains throughout the city that are used by Decatur Utilities for routine water quality monitoring. The four sampling points were selected to represent the entire city limits covering all quadrants. In addition, a sample of raw (untreated) water received from Wheeler Reservoir was collected at the Decatur Utilities WTP. The finished water samples were obtained from sampling points located in unsecured 12inch diameter PVC subsurface vaults with steel manhole covers. When sampling, the Decatur Utilities staff attached a sampling tube constructed of approximately 4 feet of Ainch (inner diameter) rigid copper tubing with soldered joints. After fitting the sampling device to the valve assembly in the vault, the valve was turned on to allow water flow at a rate of approximately 10 to 12 gallons per minute through the sampling device. After approximately one minute, the flow was reduced to approximately 2 to 3 gallons per minute to allow sampling. Flow continued at this rate for approximately one minute prior to sample collection. Following sample collection by staff from Southern Environmental Testing Inc. and Lamoreaux & Associates, WESTON collected water flowing from the sampling device into a 500-mL poly container provided by the analytical laboratory and J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-36 9 /1 6 /2 0 0 8 subsequently transferred aliquots into the appropriate sample containers. Nitrile surgical gloves were used during the sampling. Once the water samples were collected from a location, the containers were sealed, labeled, and placed into a cooled ice chest for transport. Decatur Utilities staff then stopped the flow, removed the sampling device, and covered the valve vault. The sampling device was placed into a modified piece of PVC pipe in the open bed of the Decatur Utilities truck. The sampling device was used at each sampling location without any decontamination between locations other than the flushing performed prior to sample collection. The four finished water sample locations, shown in Figure 3-13, were as follows: Station 1 - 1002 Central Parkway SW, Decatur Utilities facility, grassed area on the NE side of the Decatur Utilities building. Station 2 - 2400 13th Street SE, the southwest corner of a vacant lot within the right-of-way of 13th Street SE. Station 3 - 820 Tammy Street SW, in the right-of-way of the road adjacent to a vacant lot on the north side of Tammy Street. Station 4 - 500 Memorial Drive, a grassed median next to sidewalk. The raw water at the Decatur Utilities WTP was collected from a discharge line located in the facility's laboratory area (Station 5). The line was identified by site personnel prior to sampling and it flows continuously. The samples were collected from the flowing tap without the use of the sampling device that was used for the finished water sampling locations. The samples were submitted to the laboratory for sulfonate analyses. In addition to the February 10, 2005 sampling, finished water samples were collected on April 25, 2005; June 29, 2005; October 4, 2005; December 13, 2005; and March 1, 2006 from the laboratory at the Decatur Utilities WTP. The finished water samples were collected in the facility laboratory from a continuous flow discharge line identified by site personnel. The samples were collected directly into sample containers and submitted to the laboratory for sulfonate analyses. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-37 9 /1 6 /2 0 0 8 3.7.3.2 West Morgan/East Lawrence WTP Initial sampling was conducted at the West Morgan East/Lawrence WTP on May 3, 2005. The first samples collected were of the raw water. This sample was collected from the Wheeler Reservoir at the intake point with a dedicated polyethylene container used by the facility to collect samples. Following the raw water sample, a finished (post treatment) water sample was collected from a continuous-flow port in a laboratory sink. The plant manager identified the port before sampling. The samples were submitted to the 3M Environmental Laboratory in St. Paul, Minnesota for sulfonate analyses. Additional finished water samples were collected at the laboratory on October 4, 2005; December 13, 2005; and March 1, 2006. 3.7.3.3 Other WTPs In October 2005, sampling of finished water was conducted at other WTPs with intakes on the Tennessee River farther downstream of the 3M Decatur, Alabama facility and the West Morgan/East Lawrence County WTP. The WTPs included the Tennessee Valley Authority (TVA) research station WTP, located in Muscle Shoals, Alabama; the Muscle Shoals WTP; the Florence WTP; and the Sheffield WTP. Each WTP was sampled on a bimonthly basis over a 6-month period for a total of three samples at each location. At all locations samples were collected from a discharge line in the facility laboratory identified by site personnel. On October 4, 2005, the initial finished water samples were collected from the TVA WTP, the Muscle Shoals WTP and the Florence WTP. The Sheffield WTP was sampled on October 5, 2005. The samples were collected from monitoring points in the facility laboratory which were identified by on-site personnel prior to sampling. The ports at all of the locations flow continuously for periodic monitoring by the facility so line purging prior to sampling was unnecessary. Samples were collected directly into laboratoryprepared containers and placed into ice chests for shipment to the laboratory for sulfonate analyses. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-38 9 /1 6 /2 0 0 8 The second and third rounds of sampling at the above WTPs occurred on December 14, 2005 and March 1, 2006. The same sampling procedure was performed as for the October 2005 sampling event. The samples were sent to the laboratory for sulfonate analyses. 3.7.4 Dry Creek Wastewater Treatment Plant (WWTP), 3M Sanitary Wastewater and Morgan County Landfill Sampling of the wastewater sludge and treated wastewater effluent was conducted at the Decatur Utilities Dry Creek WWTP. The first round of sampling was conducted on May 3, 2005. Decatur Utilities staff provided access to the facility and identified appropriate sampling locations. The facility operates a sludge drying pad approximately 400 feet in length where sludge is placed for drying. Sludge is currently being hauled off-site by a contractor and land-applied. To evaluate the biosolids, one composite sample was collected from 10 sampling points along the length of the drying pad, covering the full extent of solids placed on the pad. Following collection of the solids, one grab sample of the effluent was collected at an established monitoring point located at the point of discharge from the facility into the wastewater diffuser system prior to discharge into the Tennessee River. The sludge and effluent samples were shipped to the laboratory for sulfonate analyses. In April 2006, additional samples were obtained in a single round of influent, effluent and sludge sampling at the Decatur Utilities Dry Creek WWTP and sampling sanitary wastewater effluent from the 3M Decatur facility. The Dry Creek WWTP influent and effluent samples were 24-hr composite samples, and the sludge sample was composited from multiple discrete locations within the sludge staging area. The 3M sanitary effluent was a single grab sample from the wet well of the lift station located at the 3M Decatur facility. The 3M sanitary wastewater system is separate from the 3M process wastewater system. While sanitary wastewater is conveyed to the Dry Creek WWTP for treatment, process water remains on-site for treatment in the 3M facility's WWTP. The sludge and water samples were submitted to the laboratory for sulfonate analyses. The water samples were also submitted for TDS and TSS analyses. J:\3 M -D E C A T \P F O S \F in a l\T e x t\S u lfo n a te _ D e c a tu r_ F n l_ S e c 1 to 3 .d o c 3-39 9 /1 6 /2 0 0 8 Morgan County Landfill leachate samples also were collected in June 2005 and April 2006. The leachate is hauled by means of tanker truck from Morgan County Landfill to the Dry Creek WWTP for treatment. The sample location consisted of a concrete sump approximately 25 to 30 feet deep used to accumulate the leachate from the landfill cells. The samples of the fluid were collected by lowering a polyethylene bailer into the upper portion of the fluid in order to collect the surface of the fluid. The leachate samples were shipped to the laboratory for sulfonate analyses. The April 2006 leachate sample was also submitted for TDS and TSS analyses. 3.7.5 Outfall 001 Sampling 3M's Decatur, Alabama manufacturing facilities obtain process water from Decatur Utilities and directly from the Tennessee River. In addition, many of the manufacturing operations utilize non-contact cooling water, which is obtained from the Tennessee River. All process wastewater from the 3M and Dyneon manufacturing operations is treated in the Site's wastewater treatment facility. Process wastewaters are mixed with non-contact cooling water prior to discharge to the Tennessee River. The discharge is permitted under Alabama NPDES Permit No. AL0000205. The process water/non-contact cooling water discharge is designated as Outfall 001. The location of Outfall 001 is shown in Figure 2-2. 3M conducts quarterly wastewater sampling at Outfall 001 for sulfonates analyses. 3M has monitored this outfall for a number of years as a result of 3M voluntary commitments and/or plans established through the permit with local regulators. The outfall discharges to Bakers Creek, which in turn, discharges into the Tennessee River. All samples are collected as 24-hour composites, and duplicate analysis is conducted for each sample. 3.7.6 Off-Site Marsh and Drainageway Sampling Sediment samples were collected from the previously described off-site marsh (OSM) and its surrounding drainageway in August 2007. Samples from the off-site marsh (locations EP01 through EP14) were collected using a Geoprobe rig. Sediment samples were collected from the 0 to 1 ft bgs interval at all sample locations; from the 2.5 to 3 ft J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec1to3.doc 3-40 9 /1 6 /2 0 0 8 bgs interval at locations EP02 through EP05, EP07, EP09 through EP11 and EP13; and from the 4.5 to 5 ft bgs interval at locations EP02, EP03, EP07, EP09 and EP10. Sediment samples were also collected from drainageways surrounding the off-site marsh. Five samples were collected upstream of the off-site marsh (DU01 through DU05) from the 0 to 1 ft bgs interval. Samples were collected downstream (DS01 and DS02) from the 0 to 1 ft bgs and 2.5 to 3 ft bgs intervals. Two samples were also collected from a pond area (WP01 and WP02) from the 0 to 1 ft bgs interval. This pond is located to the southwest of the off-site marsh, upgradient of the swamp area, and lies outside the drainage pathway from the off-site marsh to the swamp. Sediment samples were collected using a shovel and hand auger, which were decontaminated between sampling locations. All samples collected from the off-site marsh and surrounding drainageways were shipped to the laboratory for sulfonate analyses. Sample locations are shown in Figure 3 14.

SUMMARY OF RESULTS Over 1,000 samples have been collected from October 2004 to April 2008 for the 3M Decatur, Alabama Facility Perfluorinated Sulfonates Environmental Monitoring Program. The analytical results of sulfonate analyses are summarized in this section. Appendix D, sulfonate analytical packages, and Appendix E, data packages for ancillary parameters (i.e., TSS, TDS, TOC and grain size), are provided on a CD. 4.1 SUMMARY OF THE ANALYTICAL DATA QUALITY AND DATA REDUCTION PROCESS Analytical data for the Phase 2 study was provided by the Exygen (now MPI Research) and 3M Environmental laboratories following the Good Laboratory Practices (GLP) Protocol P1131. The GLP protocol and the specified analytical methods contain rigorous quality assurance/quality control (QA/QC) provisions including in-phase audits, full documentation, matrix spikes for every sample collected and analyzed, and thorough reviews by the respective laboratory's Quality Assurance Unit. Weston Solutions, Inc. (WESTON) also performed QA reviews. The analytical methods reflect the significant developmental effort that has been applied to refine earlier methods to obtain high-quality quantitative analytical data for sulfonates at parts per trillion (ppt) limits of quantitation, in some media. In accordance with the requirements of GLP protocol P1131, the target quantitation unit for analyses of aqueous samples (i.e., groundwater, surface water and porewater) was 25 ppt. For analyses of soil and sediment samples, the target quantitation limit was 200 ppt. In most environmental studies, duplicate analyses are performed at a frequency of only one duplicate or replicate per 10 or 20 samples (5 to 10%). To maximize the robustness of the characterization data, all sulfonates sample analyses included a laboratory replicate sample analysis, a field duplicate sample analysis or both. By accounting for media and analytical variability, the availability of multiple results for each sampling location provides more reliable point estimates of sulfonate concentrations. Where data quality objectives were J:\FOLDERS.0-9\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 4-1 9 /1 8 /2 0 0 8 not met, samples have been re-extracted and reanalyzed by the initial method or an alternate method in an effort to provide quantitative data. In some instances, method development (i.e., direct injection method as an alternate to the solid phase extraction method) has been necessary to minimize the impacts of any matrix interferences and allow quantitative analytical data to be generated. In instances where quality control (QC) data on matrix spike recoveries associated with a sample result were outside the 70 to 130% target range of acceptance for an assessed accuracy of 30%, results with matrix spike recoveries within 60 to 140% were assessed an accuracy of 40%, and those with matrix spike recoveries within 50 to 150% were assessed an accuracy of 50%. For samples with matrix spike recoveries below 50% or above 150%, the data are not reported (NR). The NR designation does not connote either high or low sample concentrations but rather reflects only that analytical conditions did not meet the criteria for field matrix spike recoveries (aqueous samples) or laboratory matrix spikes (solid samples) that would allow the reporting of quantitative data with an assessed accuracy of 50%. Other data reported with non-numerical values include results that are assigned ND because the analyte was not detected. In a few instances, where a detection occurred below the Limit of Quantitation (LOQ), the sample result was reported as not quantified (NQ). For most of the primary aqueous sample analyses, analyses were performed on a field duplicate (sample) and laboratory replicate sample of an additional aliquot from the primary sample volume. For nonaqueous environmental media samples, primary and field duplicate samples were analyzed. The primary, field duplicate and, where applicable, laboratory replicate results were reduced to a single value in order to simplify reporting. The data reduction process for purposes of this report consisted of calculating the average concentration (arithmetic mean) for sets comprised of numeric values. In instances with mixed numeric values and non-numeric values (ND or NQ), the numeric values were carried through to represent the media concentrations. The data reduction convention described above is conservative, consistent with past reporting of sulfonate data by 3M, and would likely result in overestimation of actual concentrations.

FINDINGS The following subsections present the key PFOS findings and conclusions of the Perfluorinated Sulfonate Program for the 3M Decatur, Alabama facility. PFOS was found at consistently higher concentrations than PFBS and PFHS and is the compound of greatest interest. The PFOS concentration ranges by media are presented in Table 5-1. It must be noted that 3M entered into an agreement with ADEM and has begun to cap the former sludge incorporation area and will institute a groundwater pump and treat program. 5.1 GROUNDWATER The water-bearing zones (in order from shallow to deep), which are evident at and adjacent to the 3M Decatur, Alabama facility, include: Residuum: The residuum shallow water-bearing zone, also referred to as the water table, is found within this soil layer. Epikarst: The epikarst middle water-bearing zone is found within the portion of bedrock that exhibits transitional weathering from completely weathered rock (i.e., saprolite residuum soil) to the underlying competent bedrock. Bedrock: The bedrock water-bearing zone is found within the fractures and solution cavities of the limestone bedrock. The on-site groundwater flow pathways are well characterized and understood as described in the following subsections. 5.1.1 On-Site Groundwater - Former Sludge Incorporation Area Groundwater Flow Direction At the former sludge incorporation area south of the Norfolk Southern Railroad, groundwater in each of the three water-bearing zones generally flows radially from Field 6 to the east, south and west. Groundwater flowing east is toward Bakers Creek. The residuum and epikarst groundwater, flowing south and west, appear to be intercepted by the drainage system in the southwestern portion of the Site, which directs flow to Bakers Creek. The bedrock groundwater flowing J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-1 9 /1 6 /2 0 0 8 south and west does not appear to be influenced by this drainage system and flows westward toward the BP property. At the former sludge incorporation area north of the Norfolk Southern Railroad (Fields 12 and 13), groundwater flow is to the north and west. Southwest of the former sludge incorporation area (Field 14), the drainage ditch separates Field 14 from fields where sludge was incorporated. Hydrogeologic data suggest that this drainage feature intercepts residuum groundwater that flows in a northerly direction in Field 14 and residuum groundwater from the remainder of the adjacent fields that flows in a southwesterly direction. The groundwater gradient within the bedrock groundwater is not affected by the Field 14 drainage feature and tends to flow to the northwest and west. Other Key Hydrogeologic Findings Groundwater elevations within the former sludge incorporation area indicate restricted downward vertical movement between the three groundwater zones with vertical communication occurring only in localized areas across the site. Of the three water-bearing zones, the epikarst is more transmissive and tends to be the preferred pathway for lateral groundwater flow. Geologic cross sections indicate that the thickness of the epikarst zone is variable; however, in the northern part of the former sludge incorporation area (Field 9), the thickness of the epikarst zone increases moving westward toward the property line at Finley Island Road. Potentiometric data indicate a groundwater high in all three zones associated with the area of Field 6. Geologic data for this Field 6 area suggest limited development of the epikarst system and poorly developed bedrock fracture systems impeding vertical flow in this area. This is in contrast to the northwest portion of the former sludge incorporation area (well cluster 130 in Field 9) where the epikarst is more significantly developed. On-Site Groundwater Sulfonates Analytical Data --Former Sludge Incorporation Area The analytical data are summarized in Table 4-1 and Figure 4-1. The highest PFOS concentrations were generally detected in residuum groundwater. - Field 9 - Maximum of 2,300 ppb in 131R - Field 8B - Maximum of 1,303 ppb in 134R J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-2 9 /1 6 /2 0 0 8 - Except at Fields 6 (wells 133R,S,L) and 14 (wells 136R,S,L and 137S,L), PFOS decreases in concentration with depth. The lowest PFOS concentrations generally occurred in Field 14 where no sludge was incorporated. In Field 14, well set 136R,S,L indicates an increase in PFOS concentrations with depth (1.83 ppb in 136R, 94.0 ppb in 136S, 136 ppb in 136L). The increasing concentration trend in Field 14 is likely associated with the effect of the drainage feature which intercepts shallow groundwater from the former sludge incorporation area, but not the bedrock groundwater. Therefore, as depth increases, the influence of deeper groundwater from other adjacent fields may be evident. 5.1.2 Selected Existing On-Site Monitoring Wells Groundwater - Chemical Plant and Closed Inactive Landfill Area Groundwater Flow Direction and Key Hydrogeologic Findings The selected existing monitoring wells are located on the northern portion of the 3M Decatur facility. Groundwater flow in this area of the facility is to the north and northeast toward the Tennessee River and Bakers Creek. In 2006, a groundwater recovery system was installed into the epikarst/shallow bedrock at two wells in the Chemical Plant area under a non-fluorochemical remediation program. The groundwater elevation observed at bedrock well 307L appears to be influenced by the groundwater recovery system in the Chemical Plant area, which is creating a depression in the groundwater surface in this area. A second groundwater recovery system was installed at the former incinerator pad into the residuum zone, but it pumps at only a low rate and has less influence than the Chemical Plant system. On-Site Selected Existing Monitoring Well Groundwater Sulfonates Analytical Data Chemical Plant and Closed Inactive Landfill Area The analytical data are summarized in Table 4-2 and Figure 4-2. The highest concentrations of PFOS were detected in wells 310R (702 to 1,349 ppb) and 327R (330 to 672 ppb) on the north side of the Chemical Plant near the Tennessee River and the former incinerator pad, respectively. These locations are being addressed by the groundwater recovery and treatment systems that are currently operational. The lowest PFOS concentrations occurred at bedrock well 226L (ND to 0.0369 ppb), which is southeast of the Chemical Plant and south of the facility WWTP, J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-3 9 /1 6 /2 0 0 8 and at bedrock well 320L (0.0631 ppb to 0.478 ppb), which is west of the Chemical Plant. 5.1.3 Off-Site Groundwater Groundwater Flow Direction and Key Hydrogeologic Findings The groundwater flow gradients from the former sludge incorporation area are described as follows: - The residuum and epikarst groundwater flows from the former sludge incorporation area east across State Docks Road towards Bakers Creek, south across Highway 20, and to the west across Finley Island Road. - Shallow bedrock groundwater flows east across State Docks Road towards Bakers Creek and to the west across Finley Island Road. The off-site groundwater flow gradients in the southwest are described as follows: - The residuum and epikarst groundwater flows northeasterly toward Field 14. - The shallow bedrock groundwater flows in a northwesterly direction. The Tennessee River is a hydraulic barrier to groundwater flow to the north. This is supported by a flow net analysis, which indicated that the distance into the Tennessee River from the facility's shoreline, which would receive the majority of groundwater discharge from the Chemical Plant area, is 200 feet. The Tennessee River is approximately 3 miles wide adjacent to the facility. Off-Site Groundwater Sulfonates Analytical Data The analytical data are summarized in Table 4-22 and Figure 4-39. The highest PFOS concentrations were detected in the off-site marsh (OSM) well at 994 ppb. This well is located just west of Field 9 and was formerly pumped to supply water to the off-site pond. Pumping from this well was terminated and the pond has reverted to a marsh. The remaining off-site well PFOS concentrations were approximately two orders-of-magnitude lower. The off-site groundwater concentrations at well sets 601 through 605 are one to two orders-of-magnitude lower than on-site groundwater concentrations. The PFOS concentrations at the 601 well set ranged from ND to 2.83 ppb. This well set has been abandoned. The PFOS concentrations at the remaining well sets ranged from ND at well 605L to 26.3 ppb at well 605L. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-4 9 /1 6 /2 0 0 8 5.1.4 Former Off-Site Residential Wells The analytical data are summarized in Table 4-23 and Figure 4-39. Two residential wells were identified in areas in the immediate vicinity of the site and a water sample was collected from each well. PFOS was detected at concentrations of 0.606 ppb (RESW01) and 9.20 ppb (RESW02). Residential wells RESW01 and RESW02 have been abandoned and the residences connected to Decatur Utilities public water. 5.2 SOIL 5.2.1 On-Site Soil The analytical data are summarized in Tables 4-3 through 4-5 and Figures 4-3 through 4-17. Surface Soil (0 to 6 inches bss) The lowest PFOS concentrations in surface soil occurred in Field 14 and the northwest background area locations where no sludge was incorporated. The concentrations in control Field 14 ranged from 11.5 ppb to 278 ppb. The northwest background area sulfonate concentrations were within this same range. In the former sludge incorporation area, PFOS surface soil concentrations ranged from 23.2 ppb at SS-SS04 (0 to 3 inches bgs) in Field 5 to 845,500 ppb at SSSS02 (0 to 3 inches bgs) in Field 12. The higher surface soil concentrations in the former sludge incorporation area were typically found in Fields 8b, 12 and 13. With the exception of Field 14 and the northwest background area, the lower concentrations were typically found in Field 5 (Fields 8a and 7 were not sampled). At the selected existing monitoring wells, PFOS surface soil concentrations ranged from 75.3 ppb (0 to 3 inches bgs) at 226L, east of the closed inactive landfill to 15,400 ppb (0 to 3 inches bgs) at 327R, adjacent to the former incinerator pad. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-5 9 /1 6 /2 0 0 8 Subsurface Soil PFOS was generally found throughout the entire depth of the borings down to the water table. Because PFOS was detected in groundwater in the same area, it appears that PFOS has leached from the soil and migrated vertically to the groundwater. The lowest PFOS concentrations in subsurface soil occurred in Field 14 and the northwest background area locations where no sludge was incorporated. PFOS concentrations in control Field 14 ranged from 0.238 ppb to 105 ppb. The northwest background area PFOS concentrations also were in this same range (0.665 ppb to 96.1 ppb). In the former sludge incorporation area, PFOS subsurface soil concentrations ranged from 0.368 ppb at SB-GP04 (5 to 6 ft bgs) in Field 5 to 798,000 ppb at SB-134R (5 to 6 ft bgs) in Field 8b. The highest subsurface soil PFOS concentrations in the former sludge incorporation area were detected in Field 8b at 5 to 6 ft bgs, Field 9 at 0.5 to 1 ft bgs, Field 13 at 0.5 to 1 ft bgs, Field 11 at 0.5 to 1 ft bgs, Field 12 at 0.5 to 1 ft bgs, Field 10 at 0.5 to 1 ft bgs, and Field 6 at 0.5 to 1 ft bgs. Fields 10, 11, 12 and 13 were not sampled below 6 ft bgs. At the selected existing monitoring wells, PFOS subsurface soil concentrations ranged from 6.60 ppb (17 to 18 ft. bgs) at 220R located east of the closed inactive landfill to 12,700 ppb (6 to 12 inches bgs) at 327R, adjacent to the former incinerator pad. 5.2.2 Off-Site Soil The analytical data are summarized in Table 4-21 and Figure 4-38. PFOS concentrations detected at off-site soil borings 601 through 605 were found throughout the soil column down to 11 ft bgs and ranged from ND to 51.4 ppb, which is in the same range as control Field 14 and the northwest background area concentrations. The off-site soil PFOS concentrations generally decreased with depth to the water table. 5.3 ON-SITE VEGETATION The analytical data are summarized in Table 4-6 and Figures 4-18 through 4-20. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-6 9 /1 6 /2 0 0 8  The vegetation species selected for sampling in the former sludge incorporation area were based on the dietary preferences of the hispid cotton rat. These species include pokeweed, curly dock, goldenrod, broomsedge and an unidentified grass. PFOS was detected in all the vegetation samples. The vegetation that exhibited the highest concentrations of PFOS was pokeweed, curly dock and the unidentified grass. PFOS concentrations detected in vegetation from Fields 6, 8b and 9 ranged from 99.8 ppb (Field 9) to 56,400 ppb (Field 6). The lowest PFOS concentrations in vegetation were detected in Field 14 and the northwest background area with concentrations ranging from 1.79 ppb (northwest background area) to 19.0 ppb (northwest background area). 5.4 ON-SITE SMALL MAMMALS The analytical data are summarized in Table 4-7 and Figure 4-21. The hispid cotton rat was selected as the target small mammal species because of their prevalence in the former sludge incorporation area, herbivorous dietary characteristics and ecological significance. The hispid cotton rat liver PFOS concentrations ranged from 828 ppb in Field 14 to 453,500 ppb in Field 6. The hispid cotton rat serum PFOS concentrations ranged from 303 ppb in Field 14 to 295,500 ppb in Field 8b. 5.5 SURFACE WATER (ON-SITE AND OFF-SITE) The analytical data are summarized in Tables 4-8, 4-9, 4-11, 4-12 and 4-14 and Figures 4-24 through 4-28. Off-site marsh - The highest PFOS concentrations in surface water occurred at the off-site marsh with concentrations of 326 ppb, 354 ppb and 437 ppb detected at three locations. This water body was maintained by pumping from an extraction well which, as previously noted, had measured concentrations as high as 994 ppb. The pumping has been terminated, and the marsh has returned to an emergent wetland condition with ponded water occurring only intermittently in response to precipitation events. The drainage ditch along Field 14 collects runoff from the off-site marsh and Fields 14 and 10. This ditch drains under Highway 72/20 and east to Bakers J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-7 9 /1 6 /2 0 0 8 Creek. Sulfonates were found in this drainage ditch water with PFOS concentrations ranging from 15.1 ppb at BCT01 to 279 ppb at BCT02. The Avenue A drainage ditch runs along the south side of Avenue A in the plant area. The Avenue A ditch receives overflow from Goose Pond, drainage from the landfill area and Avenue A, and drains into Bakers Creek Cove. PFOS concentrations in the Avenue A ditch were 3.16 ppb and 18.8 ppb in December 2004 and 1.62 ppb and 108 ppb in December 2006. The Goose Pond receives water pumped from the Tennessee River and runoff from the northern portion of Field 13 and adjacent areas. PFOS concentrations in surface water collected at three locations ranged from 0.560 ppb to 2.82 ppb. Tennessee River - Transect surface water samples were collected at three locations across the river. The first transect was located at the 3M facility and the other two at downstream locations. PFOS concentrations ranged from ND to 0.795 ppb. At each transect, the highest PFOS concentrations were detected on the south side of the transect closest to the shore where the facility is located. PFOS concentrations at the shoreline decreased in a downstream direction. - Longitudinal surface water samples were collected at 11 locations extending from 7 miles upstream to 46 miles downstream. PFOS concentrations ranged from ND (301, upstream) to 0.0743 ppb (RM 289, 11 miles downstream). Concentrations of PFOS in surface water generally decrease with increasing distance downstream of the facility to Wilson Lake and stabilize thereafter. - The highest PFOS concentrations in surface water collected from the fish/clam sampling areas occurred at the facility outfall (001) and Bakers Creek sampling locations, with higher concentrations of 5.86 ppb (December 2006) and 3.42 ppb (December 2004), respectively. - Field-filtered surface water samples generally had slightly lower sulfonate concentrations than their unfiltered counterparts. 5.6 SEDIMENT (ON-SITE AND OFF-SITE) The analytical data are summarized in Tables 4-8 through 4-10, 4-15 and 4-27 and Figures 4-22, 4-23, 4-25 and 4-41. Sediment sampling points discussed below were co-located with the surface water sampling points. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-8 9 /1 6 /2 0 0 8  On-site Avenue A sediment sample PFOS concentrations ranged from 32.5 ppb (December 2006) to 4,640 ppb (December 2004). The lowest concentrations were found at LOC002 and the highest concentrations were found at LOC004. On-site Goose Pond - The Goose Pond sediment sample PFOS concentrations were 10.3 ppb and 75.9 ppb at two locations. Off-site marsh and drainageway - The highest PFOS concentrations in sediment occurred at the off-site marsh with concentrations of 3,535 ppb, 4,000 ppb and 11,950 ppb in April 2006 when the pond water was being maintained by extraction well pumping. Pumping has been discontinued and previous conditions no longer exist. The following was found from the August 2007 sampling event: - PFOS sediment concentrations in the off-site marsh ranged from 75.3 ppb in the 4.5 to 5 ft bgs interval at EP03 to 1,480 ppb in the 0 to 1 ft bgs interval at EP04. - Upstream drainageway PFOS sediment concentrations ranged from 267 ppb at DU03 to 769 ppb at DU01. - Downstream drainageway PFOS concentrations ranged from 273 ppb in the 2.5 to 3 ft bgs interval at DS01 to 627 ppb in the 0 to 1 ft bgs interval at DS01. - PFOS was not detected in sediment samples collected from the downstream pond. Tennessee River and Bakers Creek - Sediment sampling was performed in the Tennessee River and in Bakers Creek at points co-located with surface water samples. - At the plant outfall (001) in Bakers Creek cove, the sediment sample PFOS concentrations ranged from 78.5 ppb (December 2006) to 480 ppb (December 2004), which were the highest concentrations in the Tennessee River/Bakers Creek. - Sediment PFOS concentrations ranged from 7.23 ppb (December 2004) to 58.2 ppb (December 2006) in the Bakers Creek samples and decreased at Tennessee River locations downstream. - PFOS was detected in only a single upriver sediment sample at 0.492 ppb (December 2006). - PFOS was not detected in cross river sediment samples.

Co-located porewater, sediment and surface water samples were collected at 12 locations near the facility shoreline. The sampling locations were approximately 100 ft off-shore and spanned an approximately 2,200-ft length of shoreline. This is the area where groundwater discharge to the river was predicted and encompassed visible seep areas. Porewater samples were collected approximately 6 to 12 inches into the base of the river bed, and it is believed that this water represents the discharge of groundwater into the river. The porewater samples PFOS concentrations ranged from 0.155 ppb to 19.5 ppb, with higher concentrations located at Station 001, Station 007, and Station 010 (located north of the Chemical Plant area). The surface water samples ranged from 0.112 ppb to 0.529 ppb, with the highest concentration located at Station 004. The sediment samples ranged from 0.810 ppb to 88.0 ppb, with the highest concentration located at Station 005. The porewater concentrations generally were greater than the co-located surface water sample concentrations. At locations STA007 through STA012, across from the Chemical Plant, the porewater concentrations were generally 1 to 2 orders-ofmagnitude greater than the co-located surface water samples. This may reflect the attenuation (dilution) that occurs when the porewater mixes with the surface water. These data tend to confirm the migration pathway of groundwater discharge to surface water (Tennessee River). 5.8 FISH AND CLAMS The analytical data are summarized in Tables 4-16 through 4-20 and Figures 4-32 through 4-37. PFOS were detected in all fish collected from the Bakers Creek cove, which receives the discharge from 3M facility WWTP outfall (DOU), and from Bakers Creek (DBC) as follows: - Largemouth bass (fillet) - 248 ppb (2006) to 9,280 ppb (2004) J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-10 9 /1 6 /2 0 0 8 - Largemouth bass (whole body) - 115 ppb (2006) to 28,200 ppb (2004) - Channel catfish (fillet) - 110 ppb (2004) to 1,070 ppb (2006) - Channel catfish (whole body) - 189 ppb (2006) to 4,735 ppb (2006) The Bakers Creek cove is the location where the largest number of detected PFOS concentrations occurred in fish samples, as well as the location where the highest surface water and sediment sample sulfonate concentrations were detected in Tennessee River/Bakers Creek. This also is the location where effluent from the facility's on-site wastewater treatment plant discharges to the Tennessee River at Outfall 001. In 2004, the maximum fish PFOS concentrations were detected at each sampling location in largemouth bass (whole body) except at Mallard Creek. At Mallard Creek, the maximum PFOS concentrations were detected in largemouth bass (fillet). In 2006, the maximum fish PFOS concentrations were detected at each sampling location in largemouth bass (whole body) except at Fox and Mallard Creeks, where the maximum concentration was detected in largemouth bass (fillet). Fish PFOS concentrations decrease going downstream from the outfall/Bakers Creek region. Upstream PFOS fish concentrations (0.306 ppb to 203 ppb) were in the same range as cross river concentrations ND to 171 ppb). PFOS was detected in all of the clam samples with concentrations ranging from 0.768 ppb to 11.2 ppb. 5.9 POTABLE WATER PLANTS The analytical data are summarized in Table 4-24 and Figure 4-40. 5.9.1 Decatur Utilities Potable Water Treatment Plant (WTP) The Decatur Utilities WTP obtains raw water from the Tennessee River upstream from the 3M facility. PFOS was not detected (ND) in the five finished water samples collected over 6 months from the Decatur Utilities WTP. 5.9.2 West Morgan/East Lawrence WTP West Morgan/East Lawrence obtains raw water from the Tennessee River approximately 15 miles downstream from the 3M facility. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-11 9 /1 6 /2 0 0 8  Samples were collected over a 10-month period. PFOS was detected in all of the finished water samples collected from the West Morgan/East Lawrence WTP with concentrations ranging from 0.0367 ppb to 0.104 ppb. 5.9.3 Other Potable WTPs Muscle Shoals obtains raw water from the Tennessee River approximately 45 miles downstream from the 3M facility. PFOS was detected in two of three samples collected from this location with concentrations of 0.0258 ppb and 0.0438 ppb. PFOS was detected in one finished water sample collected from Florence WTP at 0.0440 ppb. Florence WTP obtains raw water from the Tennessee River approximately 45 miles downstream from the 3M facility. PFOS was detected in one of the three finished water samples, collected from the Tennessee Valley Authority (TVA) research station WTP, at a concentration of 0.0425 ppb. The TVA research station obtains its raw water from the Tennessee River approximately 45 miles downstream from the facility. PFOS was detected in two of three samples collected from the Sheffield WTP (approximately 45 miles downstream) with concentrations of 0.0398 ppb and 0.0438 ppb. 5.10 DRY CREEK WWTP, 3M SANITARY WASTEWATER AND MORGAN COUNTY LANDFILL The analytical data are summarized in Table 4-25. Dry Creek WWTP discharges to the Tennessee River approximately 2 miles upstream of the 3M facility. The following are the PFOS data observed: - Influent: 0.732 ppb - Effluent: 0.571 ppb (April 2006) and 2.85 ppb (May 2005) - Dewatered sludge is staged in an area at the Decatur Utilities WWTP. A composite sample from the sludge piles was obtained on May 3, 2005 and April 13, 2006 for analysis with the following results: 2,110 (1,930 duplicate) ppb and 1,400 ppb, respectively. Morgan County leachate is trucked to the Decatur Utilities WWTP. Leachate samples were obtained on June 9, 2005 and April 14, 2006 from the concrete sump at the landfill. Sample analysis indicated that PFOS was detected at concentrations of 43.2 ppb and 27.4 ppb, respectively. J:\3M-DECAT\PFOS\Final\Text\Sulfonate_Decatur_Fnl_Sec4to6.doc 5-12 9 /1 6 /2 0 0 8  The only discharge from the 3M facility to the Decatur Utilities Dry Creek plant is their sanitary wastewater. Process and industrial wastewater goes to the on-site WWTP. A grab sample collected from the 3M sanitary wastewater at the manhole leaving the plant showed a PFOS concentration of 4.48 ppb. Considering flow rates and sulfonate concentrations, the mass of PFOS contributed from the Morgan County Landfill leachate and the 3M sanitary wastewater is not significant when compared to the Dry Creek influent/effluent mass. 5.11 OUTFALL 001 The analytical data are summarized in Table 4-26. Outfall PFOS concentrations ranged from 2.41 ppb in a sample collected in December 2006 to 57.0 ppb in a sample collected in November 2003.
