RESOLUTION CONSULTANTS Resolution Consultants A J o in t Venture ofAECO M & EnSafe 510 Carnegie Center Princeton, New Jersey 08540 Technical Memorandum Perfluorinated Compounds Soil and Groundwater Investigation Shenandoah Woods Housing Complex Naval Air Warfare Center, Warminster, Pennsylvania 19 March 2015 through 31 May 2015 1.0 INTRODUCTION This Technical Memorandum summarizes the findings of a soil and groundwater investigation performed by Resolution Consultants (Resolution) at the Shenandoah Woods Housing Complex, located at the former Naval Air Warfare Center (NAWC) Warminster between 19 March 2015 and 31 May 2015, under Naval Facilities Engineering Command (NAVFAC) Atlantic, Comprehensive Long Term Environmental Action, Navy (CLEAN) Contract No. N62470-11-D-8013, Contract Task Order (CTO) WE 28, 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 the 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 perfluorinated 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 study. The PHAs for PFOS and PFOA are not directly applicable to soil. 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). This investigation was initiated at Shenandoah Woods in 2015 to support property transfer by characterizing the occurrence and concentrations of six PFCs: PFOA, PFOS, PFNA, PFHxS, PFHpA and PFBS, in soil and groundwater. During this investigation, eight soil samples and one blind duplicate were collected from four boring locations and 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 Figures 1 and 2. US00008222 RESOLUTION CONSULTANTS Resolution Consultants A J o in t Venture ofAECO M & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 2.0 FIELD ACTIVITIES As part of this investigation, soil borings were advanced and three dual-nested monitoring well pairs were installed in the Shenandoah Woods parcel. On 19 March 2015, a geophysical survey was performed by PULS, Inc. of Bethlehem, PA under Resolution oversight for utility clearance purposes in each of the proposed boring and monitoring well locations. Soil Borings On 23 March and 24 March 2015, two soil borings (SB01 and SB02) were advanced using direct push technology to 5.5 feet below ground surface (bgs) and four soil samples, one blind duplicate, and one matrix spike/matrix duplicate were collected from the boring sidewall from depths between 0.5 feet bgs to 3 feet bgs. Soil samples were collected above perched groundwater encountered at approximately 3.5 feet bgs. Soil borings were advanced at two of the nested monitoring well locations. Four soil samples were collected from the sidewall of two monitoring wells (HN-107 and HN-109). Soil samples were collected at depths ranging from 0.8 feet bgs to 8 feet bgs. Monitoring Well Installation Dual nested monitoring well pair locations were selected hydraulically down-gradient of Sites 5, 6, and 7. Well installation details are summarized below. On 23 March through 27 March 2015, the initial boreholes were advanced at the HN-107, HN-108, and HN-109 locations (Figure 2). 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, the target depths for shallow monitoring wells were approximately 50 feet below ground surface (bgs) and 100 feet bgs for the intermediate monitoring wells. At each location, a 10-inch carbide hammer was used to advance borings to 20 feet bgs and 10inch steel outer casing was installed. Borings were advanced through the outer casing to the maximum depth of 100 feet bgs using an 8-inch carbide hammer. Two flush mounted, 2-inch diameter monitoring wells were completed at each location. Monitoring wells were constructed with 2-inch polyvinyl chloride (PVC) well screen and riser. The annular space was filled with Number 1 sand to two feet above the well screen. Filter pack material was used under the sump cap (minimum of 6 inches). To seal the annular space between the shallow and intermediate wells, a five foot thick (minimum) hydrated bentonite plug was installed above the filter pack and the monitoring well was sealed above the shallow screen using bentonite slurry via pressure grout injection to 0.5 feet bgs. The well seal cured for 24 hours prior to surface completion of the well pad. After 24 hours, no loss of annular space grout to the formation was observed. A 10-inch diameter man-hole cover was installed within a 2 foot by 2 foot concrete pad at each well location. Monitoring wells were developed on 2 April 2015. Soil cuttings and groundwater generated during drilling were captured by an in-line containment system. Soil cuttings were containerized in a roll-off and groundwater generated during drilling and well development purge water were containerized in drums. The roll-off and drums were transported to the NAWC groundwater treatment plant. The roll off was removed for disposal, the drums were removed for off site disposal 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 construction details are summarized in Table 1 and the well locations are shown in Figures 1 and 2. Boring logs and well construction diagrams are included in Attachment 1. 2 April 2016 US00008223 RESOLUTION CONSULTANTS Resolution Consultants A J o in t Venture ofAECO M & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 Groundwater Sampling On 16 April 2015, monitoring wells were gauged and sampled in accordance with EPA Region 1 LowStress 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 all six monitoring wells. Well screen intervals were selected based on where saturated conditions and/or fractures were encountered during drilling. During drilling, weathered bedrock was noted in the upper 55 to 77 feet of the boring, which gradually transitioned into competent Stockton Formation bedrock. This 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 Area C, lithologic boring data and the depths groundwater was encountered in monitoring wells HN-107 S/l, HN-108 S/l, and HN-109 S/l suggest confined to semi confined conditions. Generally, the lithology identified was highly weathered from the surface until approximately 55 to 77 feet bgs. Finer grained materials (siltstone and mudstone) were identified above the more permeable sandstone units and fractures. 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 There are no screening levels for PFCs in soil, however, constituents of interest were not detected above the laboratory detection limits in soil samples with the exception of SB7. The sample collected from SB7 at 0.5 feet bgs had an estimated (J) PFOS concentration (6.040 J pg/kg). The concentration of PFOS in the accompanying blind duplicate of SB7 was below the detection limit for all analytes. Analytical results from eight of the nine soil samples collected during this investigation were below reporting limits for all six PFC analytes. Analytical results from the soil investigation are summarized in Table 2. Concentrations of PFOS and PFOA in the groundwater samples collected on 16 April 2015 were below their respective EPA PHA in all monitoring wells sampled except PFOS in HN-1081. PFOS detected in the groundwater samples collected from HN-1081 (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. 3 April 2016 US00008224 RESOLUTION CONSULTANTS Resolution Consultants A J o in t Venture ofAECO M & EnSafe 510 Carnegie Center Princeton, New Jersey, 08540 Concentrations of PFOA were higher than PFOS in all samples collected except HN-1081. The highest concentration of PFOA was detected in monitoring well HN-1091 (0.0718 pg/L), which is below the PHA of 0.4 pg/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-1081 (0.134 pg/L). The concentration of all analytes were below their respective detection limits in all field blanks, collected each day of sampling.

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 (COC)/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. 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. US00008262 Resolution Consultants 3 Holding Times/Sample Preservation Sample preservation and preparation/analysis holding times were reviewed for conformance with the QC acceptance criteria. All QC acceptance criteria were met. Initial Calibration/initial 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, field blanks and equipment rinsate blanks were evaluated as to whether there are contaminants detected above the detection limit (DL). Target compounds were not detected in the laboratory method blank, field blanks or equipment blanks 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 with the QC acceptance criteria. All QC acceptance criteria were met. Field Duplicate Results Field duplicate RPDs were reviewed for conformance with the Resolution Consultants QC criteria of <50% for solid 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.

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 field blanks associated with the samples in this data set. The method blank associated with samples HN-107S, HN-1071, HN-109S, HN-1091, DUP-041615 and FB-041615 contained Perfluorohexanesulfonic Acid (PFHxS) [0.00863 J pg/L] and Perfluorooctanesulfonic Acid (PFOS) [0.102 pg/L]. Since the PFOS amount in the method blank exceeded the reporting limit (RL), re-extraction of all associated samples was performed with two exceptions: 1) Sample HN-107S was not re-extracted because there was insufficient sample volume available for re-extraction and 2) The field blank FB-041615 was not re-extracted since no target compounds were detected in this blank. However, it should be noted that the re-extraction was performed outside of the 14-day extraction holding time criterion. Although the method blank associated with the re-extraction batch was free from contamination, professional judgement was used to report the original analyses which were performed within holding time and without qualification since the method blank contamination in the original batch appears to be an anomaly. The sample results in the re-extraction/reanalysis were similar to the original analyses of these samples and the field blank (FB-041615) prepared in the original batch was free from contamination. 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.
