The former NAWC Warminster is an 824-acre facility located in Warminster Township, Northampton Township, and Ivyland Borough, Bucks County, PA. As a result of the Defense Base Realignment and Closure Act (BRAC), NAWC Warminster was closed on 31 March 1997; the entire property, except for the Shenandoah Woods parcel, has been transferred to the private sector for redevelopment. Custody of the Shenandoah Woods Housing Complex on the NAWC Warminster property was transferred to NASJRB Willow Grove located in nearby Horsham Township, Montgomery County, Pennsylvania. Historic waste disposal locations were grouped within three general areas on the former NAWC property (see Figure 1): Area A (Sites 1, 2, and 3), Area B (Sites 5, 6, and 7), and Area C (Sites 4 and 8). A fourth general area (Area D) primarily includes the former main building complex at the former NAWC Warminster. This perfiuorinated compounds (PFCs) investigation focused on the former Navy housing area, consisting of approximately 55 acres, which includes a portion of Site 5 of Area B. PFCs are persistent in the environment and are an emerging class of environmental contaminants. PFCs are used to make a wide range of products including oil-, stain-, heat-, and water-resistant materials such as clothing (i.e. GORE-TEX), carpeting (i.e. ScotchguardTM), furniture, food packaging (i.e. popcorn bags), flooring (i.e. StainmasterTM), non-stick cookware (i.e. Teflon), stain/water resistant paint, and roofing materials. They were also used as surfactants in metal plating baths, shampoos, moisturizers, shaving cream, oil well surfactants, aqueous film forming foam (AFFF), and semiconductor baths. Additional applications of PFCs include use in rust inhibitors, starting materials for herbicides/pesticides, acid mist suppressants, aviation hydraulic fluids, and adhesives. (Tetra Tech 2014). Short-term Preliminary Health Advisories (PHA) were developed by the USEPA for perfluorooctanesulfonic acid (PFOS) (0.2 micrograms per liter (pg/L)) and perfluorooctanoic acid (PFOA) (0.4 pg/L) to reduce potential exposure through drinking water (EPA 2009 and 2014). Currently, there are not PHAs for the remaining four PFCs (perfluorononanoic acid [PFNA], perfluorohexanesulfonic acid [PFHxS], perfluoroheptanoic acid [PFHpA] and perfluorobutanesulfonic acid [PFBS]) evaluated during this sudy. PFCs (PFOA and PFOS) were identified in on-site and off-site wells in the vicinity of NAWC Area C during the five year review (Tetra Tech 2011). Sampling for PFCs was initiated at Shenandoah Woods in 2015 in support of property transfer (Resolution, 2015). Monitoring wells HN-107, HN-108, and HN109 were installed and soil samples collected from 23 March through 27 March 2015. Soil sample results were below the laboratory detection limits except for SB7 (PFOS 6.040 J pg/kg). The monitoring wells were sampled on 16 April 2015. Concentrations of PFOS and PFOA in the groundwater samples were below their respective EPA PHA in all monitoring wells sampled except PFOS in HN-1081. PFOS 1 April 2016 US00008270 RESOLUTION CONSULTANTS Resolution Consultants A Jo in t Venture ofAECOM & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 detected in the groundwater samples collected from HN-1Q8I (0.236 pg/L) exceeded the PHA for PFOS (0.2 pg/L). Detectable concentrations of PFOS and PFOA were reported in all groundwater samples collected except in those obtained from HN-108S. This additional investigation was initiated to further characterize the occurrence and concentrations of six PFCs: PFOA, PFOS, PFNA, PFHxS, PFHpA and PFBS in groundwater at Shenandoah Woods. Installation of monitoring wells was requested by the Pennsylvania Department of Environmental Protection to determine if PFCs are present in shallow groundwater and might be discharged by basement sump pumps if the area is redeveloped. A maximum depth for each well of 25 feet below ground surface (bgs) was proposed to account for the possible future use of basement sump pumps. The six PFCs were analyzed to be consistent with previous investigations. During this investigation, groundwater samples were collected from six monitoring wells with one blind duplicate. Groundwater data for PFOS and PFOA were compared to the PHAs. PFC sample locations are shown on Figure 1. Note that three dual-nested monitoring well pairs were installed in Shenandoah Woods during previous investigation activities performed in April 2015. These wells are also shown on Figure 1; but were not sampled during the July 2015 groundwater sampling event. 2.0 FIELD ACTIVITIES Between 4 June and 12 June 2015, six monitoring wells were installed and developed at Shenandoah Woods (Site 5) to identify potential PFC impacts to shallow groundwater. The wells were sarhpled approximately two weeks later on 30 June and 1 July 2015. Monitoring Well Installation Monitoring well locations were selected in accessible areas within the residential portions of Shenandoah Woods. Well installation details are summarized below. On 4 June 2015, a geophysical survey was performed by PULS, Inc. of Bethlehem, PA under Resolution oversight for utility clearance purposes in each of the six proposed well locations. On 8 June and 9 June 2015, the initial boreholes were advanced at the HN-110 to HN-115 locations (Figure 1). The boreholes were advanced by Raab Drilling of Perkasie, PA, a Pennsylvania licensed driller, using an air rotary drill rig, under oversight of a Resolution geologist. Based on previous investigations at the Site and discussions with the US EPA, the target depth for the monitoring wells was a maximum of 25 feet bgs. At each location, a 10-inch carbide hammer was used to advance borings to 25 feet bgs. Six flush mounted, two-inch diameter monitoring wells were completed at each location. Monitoring wells were constructed with two-inch polyvinyl chloride (PVC) 0.01-inch well screen and riser. The annular space was filled with Number 1 sand to two feet above the well screen. The monitoring well was sealed above the screen using bentonite slurry via pressure grout injection to 1-foot bgs. The well seal cured for 24 hours prior to surface completion of the well pad. Monitoring wells were developed on 11 June and 12 June 2015. Soil cuttings and groundwater generated during drilling and well development purge water were containerized in drums. The drums were transported to the NAWC groundwater treatment plant where they were staged pending characterization and off-site disposal. Off site disposal was completed on 23 July 2015 Completed monitoring wells were surveyed in Pennsylvania South State Plane, UTM Zones 17 and 18, by R.L. Showalter & Associates of Chalfont, PA. A well construction table is provided as Table 1. Well locations are shown on Figure 1. Boring logs and well construction diagrams are included in Attachment 1. 2 April 2016 US00008271 0) RESOLUTION CONSULTANTS Resolution Consultants A Jo in t Venture ofAECOM & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 Groundwater Sampling On 30 June and 1 July 2015, monitoring wells were gauged and sampled in accordance with US EPA Region 1 Low-Stress Sampling Guidance (EPA 2010). Precautions were taken to avoid sample contamination and/or bias during collection per the draft Sampling and Analysis Plan (SAP) (Battelle, 2015). Products containing Teflon were not used during sample collection, handling, or transportation. Sampling personnel did not use any waterproof items, wore only well-laundered clothing, and attempted to identify and isolate any potential PFC-containing materials that might cross-contaminate groundwater samples. . During gauging, depth to groundwater was measured above the well screens in three of the six monitoring wells (HN-111, HN-114, and HN-115). Groundwater was encountered during drilling at 21 feet bgs in HN-110, 24.5 feet bgs in HN-111, 22 feet bgs in HN-112, 18 feet bgs in HN-114, and 22 feet bgs in HN-115. Water was not encountered in HN-113 during drilling. Well screen intervals were proposed from 15 to 25 feet bgs to coincide with the depths of sump pumps that may be installed in basements if/when the land is redeveloped. Monitoring well screens were set from 15 to 25 feet based on the depths of water encountered during drilling; however, water levels rose after well installation. During drilling, weathered bedrock was noted through the entire boring column to 25 feet bgs. The depth of weathered bedrock is consistent with a geophysical investigation designed to investigate bedrock water-bearing fractures beneath the site at Area C (U.S. Geological Survey 2008). Area C was divided by the U.S. Geological Survey into shallow and deep hydrogeologic units. The shallow unit is comprised of sandstone. The deep hydrogeologic unit is defined as water-bearing bedrock beneath the shallow hydrogeologic unit, and typically exhibits artesian conditions (Batelle 2015). Consistent with shallow hydrogeologic conditions at Area C, boring data from monitoring wells HN-110 through 115 does not suggest confined or semi confined conditions. Groundwater was purged using dedicated, high-density, polyethylene tubing that was discarded after each sample was collected. Groundwater was extracted using a stainless steel submersible pump that was decontaminated before each use with distilled water and Alconox detergent. Monitoring wells were purged continuously until water quality parameters (pH, conductivity, dissolved oxygen, and turbidity) stabilized. Once parameters stabilized, groundwater samples were collected for analysis in clean, laboratory-supplied, PFC-free, high-density polyethylene bottles. A blind duplicate and a field blank were collected using laboratory-certified, PFC-free, deionized water. Matrix spike and matrix spike duplicate samples were collected and analyzed at a rate of one per 20 samples. Samples were packaged with ice in a cooler, and shipped via laboratory courier under chain-of-custody to Accutest Laboratories of Orlando, Florida (Attachment 2). Samples were analyzed for PFCs using EPA Method 537 modified for environmental media. Data validation was completed by the Resolution Project Chemist. The data were found to be valid as reported and suitable for decision-making purposes. The data validation report is provided in this document as Attachment 3. 3.0 RESULTS Detectable concentrations of PFOS were reported in all groundwater samples collected on 30 June and 1 July 2015 and PFOA was detected in all samples except HN-112 and HN-113. However, concentrations of PFOS and PFOA in the groundwater samples were below their respective EPA PHA's in all monitoring wells sampled. Where they were detected, concentrations of PFOS were higher than PFOA in all samples. The highest concentration of PFOS was detected in monitoring well HN-110 (0.127 jjg/L). The most common detection of the four additional analyzed PFCs without PHAs was PFHxS, which was reported in all of the groundwater samples. The highest concentration of PFHxS was detected in monitoring well HN-110 3 April 2016 US00008272 RESOLUTION CONSULTANTS Resolution Consultants A J o in t Venture ofAECOM & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 (0.0475 |jg/L).

Data validation activities were conducted with reference to: Accutest Laboratories SOP: Analysis of Perfluorinated Alkyl Acids by LC/MS/MS; MS 014.1, Rev. Date: 05/14 USEPA Contract Laboratory Program National Functional Guidelines for Chlorinated Dioxin/Furan Data review (USEPA, September 2011); USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review (June 2008); and Quality Systems Manual (QSM) for Environmental Laboratories, Version 4.2 (DoD, October 2010) Resolution Consultants 2 In the absence of method-specific information, laboratory quality control (QC) limits, project-specific requirements and/or professional judgment were used as appropriate. REVIEW ELEMENTS The data were evaluated based on the following review elements (where applicable to the method): / Data completeness (chain-of-custody (CQC)/sample integrity / Holding times/sample preservation / Initial calibration/initial and continuing calibration verification / Laboratory method blanks/equipment blanks / Surrogate recoveries / Matrix spike (MS) and/or matrix spike duplicate (MSD) results / Laboratory control sample (LCS) results / Field duplicate results / Internal standard results / Sample results/reporting issues The symbol ( / ) indicates that no validation qualifiers were applied based on this parameter. An NA indicates that the parameter was not included as part of this data set or was not applicable to this validation and therefore not reviewed. The symbol ( X ) indicates that a QC nonconformance resulted in the qualification of data. Any QC nonconformance that resulted in the qualification of data is discussed below. In addition, nonconformances or other issues that were noted during validation, but did not result in qualification of data, may be discussed for informational purposes only. The data appear valid as reported and may be used for decision making purposes. Qualification of the data was not required. RESULTS Data Completeness/Sample Integrity The data package was reviewed and found to meet acceptance criteria for completeness: The COCs were reviewed for completeness of information relevant to the samples and requested analyses, and for signatures indicating transfer of sample custody. The laboratory sample login sheet(s) were reviewed for issues potentially affecting sample integrity, including the condition of sample containers upon receipt at the laboratory. Completeness of analyses was verified by comparing the reported results to the COC requests. US00008311 Resolution Consultants 3 Holding Tiroes/Sample Preservation Sample preservation and preparation/analysis holding times were reviewed for conformance with the QC acceptance criteria. All QC acceptance criteria were met or qualification of the data was not required. Initial Calibration/lnitial and Continuing Calibration Verification Calibration data were reviewed for conformance with the QC acceptance criteria to ensure that: the initial calibration (ICAL) percent relative standard deviation (%RSD) or correlation coefficient (r)/coefficient of determination (r2) method acceptance criteria were met; the initial calibration verification standard (ICV) percent recovery acceptance criteria were met; and the continuing calibration verification standard (CCV) frequency and method percent recovery criteria were met. The QC acceptance criteria were met. Laboratory Method Blanks/Eguipment Blanks Laboratory method blanks and field blanks are evaluated as to whether there are contaminants detected above the detection limit (DL). Target compounds were not detected in the laboratory method'blank or field blank [FB-07012015] associated with the samples in this data set. Surrogate Recoveries The surrogate recoveries (%Rs) were reviewed for conformance with the QC acceptance criteria. All QC acceptance criteria were met or qualification of the data was not required. MS/MSD Results The MS/MSD %Rs and relative percent differences (RPDs) were reviewed for conformance with the QC acceptance criteria. All QC acceptance criteria were met. LCS Results The LCS %Rs were reviewed for conformance. All QC acceptance criteria were met. Field Duplicate Results Field duplicate RPDs were reviewed for conformance with th Resolution Consultants QC criteria of <30% for aqueous matrices. These criteria apply if both results were greater than five times the limit of quantitation (LOQ). All field duplicate precision criteria were met. Internal Standard Results The internal standard (IS) results were reviewed for conformance with the QC acceptance criteria. All QC acceptance criteria were met. US00008312 Resolution Consultants 4 Sample Results/Reportinq Issues . If applicable, compounds detected at concentrations less than the limit of quantitation (LOQ) but greater than the detection limit (DL) were qualified by the laboratory as estimated (J). This "J" qualifier was retained during data validation, QUALIFICATION ACTIONS Qualification of the sample data was not required. US00008313
