(Geosyntec) for The Chemours Company, FC, LLC (Chemours) pursuant to Paragraph 11.2 of the executed Consent Order (CO) dated 25 February 2019 among the North Carolina Department of Environmental Quality (NCDEQ), Cape Fear River Watch (CFRW), and the Chemours Company FC, LLC (Chemours). Paragraph 11.2 requires an assessment of the nature and extent of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in sediment in the Cape Fear River originating from the Facility. PFAS are a category of chemicals comprised of many thousands of compounds (Wang et al., 2017). PFAS compounds are widely detected in environmental samples across the country and are introduced into watersheds via common sources including discharge from industrial processes, effluent from wastewater treatment plants, leachate from landfills, and releases of firefighting foams (ITRC, 2020; Hu et al., 2016). This sampling program evaluated the nature and extent of PFAS in the Cape Fear River which can be analyzed by two methods currently available: Method 537M and the Table 3+ Method. Method 537M PFAS compounds are often associated with effluents from wastewater treatment plants and firefighting foams, amongst other sources. Table 3+ Method PFAS compounds are often related to operations at the Chemours Fayetteville Works Site (the Site). Surface water and sediment samples were collected in the Cape Fear River from nine transects along the length of the River in May and June 2020 to evaluate PFAS concentrations upstream of, adjacent to, and downstream of the Site. Sediment and surface water samples were analyzed by the Table 3+ Method and Method 537M. Sediment samples were also analyzed for geotechnical properties including grainsize and total organic carbon content. Sediment samples were collected from riverbank and mid-channel River segments. A higher relative percentage of fine-grained sediment was found in riverbank samples compared mid-channel samples (see inset figure below), consistent with expected river dynamics where banks with lower water velocities are more depositional than thalweg1 areas with higher water velocities. Higher fines contents were also associated with higher total organic carbon contents. Many compounds preferentially adsorb to finer grained sediments (often the total organic carbon component), which makes grain size 1 The thalweg is a line connecting the deepest points of successive cross-sections along the course of a river. TR0795A viii October 2020 distributions and total organic carbon concentrations indicators of areas with potential sediment impacts (ITRC, 2014). The inset figure below shows PFAS detections were generally found in finer grained sediment with higher total organic carbon concentrations. Method 537M PFAS were detected above reporting limits in sediment from all nine transects; Table 3+ PFAS were detected above reporting limits in sediment in three transects, which were located alongside the Site and in a depositional area downstream of the Site. Sediment Grain Size, Total Organic Carbon, and PFAS Data Method 537M PFAS have been identified in upstream sources collected by NCDEQ and the PFAST Network (NCDEQ, 2020; PFAST Network, 2020). In general, the presence of Method 537M PFAS in the watershed is consistent with known patterns of PFAS contributions to watersheds from upgradient sources such as effluent from wastewater treatment plants, leachate from landfills, and releases of firefighting foams (ITRC, 2020; Hu et al., 2016). In this program, Method 537M PFAS were detected in surface water above reporting limits at each sampling transect. The total concentration of Method 537M PFAS did not change meaningfully upstream or downstream of the Site. Past investigations conducted by Chemours have also demonstrated that Method 537M PFAS do not increase in concentration from immediately upstream to downstream of the Site (Geosyntec, 2018). Table 3+ PFAS were detected in surface water above reporting limits at each sampling transect with concentrations becoming highest downstream of the Site TR0795A ix October 2020 where Site inputs of Table 3+ PFAS to the Cape Fear River are well mixed across the river water column. The sediment and surface water samples collected in this program were compared to data collected and interpretations made in the 2019 Human Health and Ecological SLEAs (Geosyntec, 2019a). The results of this program are consistent with the findings of the SLEAs that, based on presently available information for HFPO-DA exposures quantified, there are no anticipated hazards to human or ecological receptors from exposures to HFPO-DA in surface water or sediment. Concentrations of HFPO-DA were below the 140 ng/L HFPO-DA provisional health goal (NCDEQ and North Carolina Department of Health and Human Services [NCDHHS], 2018). Additionally, in the Cape Fear River, the combined concentrations of PFOA and PFOS (Method 537M) in surface water from all locations sampled in this program were below the 70 ng/L USEPA Lifetime Health Advisory level (USEPA, 2016b, 2016c). TR0795 1 October 2020 1 INTRODUCTION Geosyntec Consultants of NC, P.C. (Geosyntec) has prepared this Sediment Characterization report for The Chemours Company, FC, LLC (Chemours) pursuant to requirements of Paragraph 11.2 of the executed Consent Order (CO) among Chemours, North Carolina Department of Environmental Quality (NCDEQ) and Cape Fear River Watch (CFRW) dated 25 February 2019. Chemours operates the Fayetteville Works facility in Bladen County, North Carolina (the Site). In August 2019, pursuant to requirements of CO Paragraph 11.2, Geosyntec developed a plan to assess the nature and extent of per- and polyfluoroalkyl substances (PFAS) contamination originating from the Site in Cape Fear River sediments; the Plan was amended following one round of comments by NCDEQ and accepted by NCDEQ in April 2020 (Sediment Characterization Plan, Geosyntec, 2020a). This Characterization Plan included the selection of transects for collection of sediment and surface water samples upstream, adjacent to, and downstream of the Site, as well as near raw water intakes of downstream public water utilities. The Sediment Characterization Plan described the intended sampling locations and methods. The objective of this Sediment Characterization Report is to describe the findings of surface water and sediment samples collected during the Sediment Characterization (referred to herein as “this program”) of the Cape Fear River. Data collected were used to assess Total Table 3+ and Method 537M per- and polyfluoroalkyl substances (PFAS) in the Cape Fear River sediment and surface water. The Table 3+ Method was developed by Chemours and its analytical laboratory partners. Certain compounds analyzed by the Table 3+ method were identified by non-targeted analysis of samples collected from the Site; non-targeted analysis is a specialized analytical approach that evaluates samples for the presence of unknown compounds. Based on the non-targeted analysis results, the Table 3+ method was then developed to enable a targeted analytical method to analyze for these PFAS. Presently, the grouping of PFAS referred to as Table 3+ are analyzed by the Table 3+ Method, and PFAS referred to as Method 537M are analyzed by a modification to the EPA Method 537. The remainder of this report is organized as follows: • Setting and Approach – This section describes the approach used to achieve the CO objectives for the Sediment Characterization and the reason for selecting each sampling transect in the Cape Fear River; • Scope and Methods – This section describes the sampling performed and methods used in the sampling activities; TR0795 2 October 2020 • Sampling Results – This section presents the results of the Cape Fear River Table 3+ PFAS and Method 537M sampling in Sediment and Surface Water; • Discussion of Sampling Results – This section describes river sediment transport dynamics, then analyzes the results of Cape Fear River sediment and surface water sampling results including sediment grainsize, Total organic carbon (TOC) and PFAS data, and provides an interpretation of results with regard to the Human Health and Ecological Screening Level Exposure Assessments (SLEAs); and • Summary – This section summarizes the objectives and findings of this report. 2 SETTING AND APPROACH The Cape Fear River flows 191 miles from its start at the confluence of the Deep and Haw Rivers to its mouth in the Atlantic Ocean near the city of Wilmington, NC (Figure 1). Along its course, the Cape Fear River receives contributions from a variety of sources including the Little River, various creeks, direct groundwater discharge to the Cape Fear River, and discharges from multiple publicly owned treatment works (POTWs). The Site is located approximately 76 miles from the confluence of the Deep and Haw Rivers (Figure 2). The objective of this Characterization was to assess the nature and extent of PFAS originating from the Site to Cape Fear River sediments. To achieve this objective, samples were collected from Cape Fear River sediments and surface water in upstream, Site-adjacent, and downstream reaches of the Cape Fear River. This approach was detailed in the NCDEQ-approved Sediment Characterization Plan (Geosyntec, 2020a). Nine transects (Figure series 3a-h) were selected for sampling; the reason for selecting each transect is as follows: • Cape Fear River Mile 202: Intended to be collected near the surface water sample collected at River Mile 20 in June 2018. This transect was selected to be representative of background conditions. It is located near United States Geologic Society (USGS) Stream Gage 02102500 and Harnett County's drinking water intake. • Cape Fear River Mile 52: Intended to be collected near the surface water sample collected at River Mile 52 in June 2018. This transect was selected to be 2 River miles are numbered from upstream to downstream. River Mile Zero corresponds with the beginning of the Cape Fear River. TR0795 3 October 2020 representative of background conditions. It is located near the City of Fayetteville's drinking water intake. • Cape Fear River Mile 76: Transect collected directly upstream of the confluence with Willis Creek. This transect was intended to be collected near the CFR-05 surface water samples collected September 2017 and May 2018. This transect is considered adjacent to the Site. • Cape Fear River Mile 77: Transect located immediately downstream of Outfall 002, upstream of dam. This transect is considered adjacent to the Site. • Cape Fear River Mile 84: Intended to be collected near the surface water sample collected at River Mile 84 in June 2018 in which the highest concentration of Hexafluoropropylene Oxide Dimer Acid (HFPO-DA) was detected above reporting limits during the June 2018 surface water sampling event. This transect is downstream of Site; and located upstream of and within 1,000 feet of the Bladen Bluff Drinking Water Intake (River Mile 84.8). • Cape Fear River Mile 100: Intended to be collected near the surface water sample collected at River Mile 100 in June 2018. This transect is downstream of Site. The Elizabethtown Wastewater Treatment Plant (WWTP) outfall discharge is located near this sample. • Cape Fear River Mile 116: Intended to be collected near the surface water sample collected at River Mile 116 in June 2018. This transect is downstream of Site. • Cape Fear River Mile 132: Intended to be collected near the surface water sample collected at River Mile 132 in June 2018. This transect is downstream of Site. Sample co-located with the Kings Bluff Intake Canal operated by the Lower Cape Fear Sewer and Water Authority and distributes water to CFPUA (New Hanover county), Brunswick County and Pender County. • Cape Fear River Mile 149: Located downstream of Cape Fear River Lock and Dam #1 and Kings Bluff Intake Canal, located 42 miles upstream from where the Cape Fear River empties into the Atlantic Ocean. This transect is 72 river miles downstream of Site. 3 SCOPE AND METHODS For this Characterization, sampling was conducted by Geosyntec and Parsons of NC (Parsons) staff in May and June 2020. The scope of the sampling programs and methods employed to collect field data are summarized below. TR0795 4 October 2020 3.1 Sampling Locations Transect locations were field-adjusted so at least one sample along each transect was confirmed to contain at least 20% fine-grained material (confirmed by field-sieving with a #200 mesh screen). Each transect was then divided into three segments. Facing upstream, the left bank segment was given an “A” designation, the mid-channel segment was given a “B” designation and, and the right bank segment was given a “C” designation (Figure series 3a-h). Collectively samples from “A” and “C” segments are referred to as bank samples while samples from the “B” segments are referred to as mid-channel samples. Water column samples were collected from the mid-channel segment (“B” designation) in each transect. Where water depths exceeded 3 feet, two water column samples were collected, one from one to two feet above the sediment surface, and one from the approximate midpoint of the water column (this occurred at 7 transects; Table 2). Where water depths were shallower than 3 feet, one water column sample was collected from the approximate midpoint of the water column (this occurred at two transects; Table 2). Surficial sediment samples were collected from each segment along each transect (“A”, “B”, and “C” designations). Samples were collected from the sediment surface to a depth of approximately four inches. Transects were located in the main Cape Fear River channel except for the transect at River Mile 149, which was located in a secondary flow channel from the main channel. Sampling segments are shown in Figure series 3a-h. Sample segment coordinates, which were recorded by a Garmin Glo GPS unit, are provided in Table 1. 3.2 Sampling Methods 3.2.1 Sediment Sampling Procedures Sediment sampling was conducted in general accordance with United States Environmental Protection Agency (USEPA) standard operating procedure (SOP) SESDPROC-200-R3 Sediment Sampling (USEPA, 2014) and the approved Characterization Plan (Geosyntec, 2020a). Sediment samples were collected from all segments with a Wildco® stainless steel petite ponar (referred to herein as a ponar), except for one sample which was composed of tight clay which the ponar could not penetrate; this sample was hand collected from sediment just above the waterline using a stainless-steel spoon (River Mile 116, segment “A”). At the request of NCDEQ, duplicate samples from three segments were additionally TR0795 5 October 2020 collected using a push-tube device (River Miles 76, 84, and 149). Split samples were collected at River Miles 52 and 149 using a ponar. Additional material was collected from sediment segments collected from “A”, “B”, and “C” segments from River Miles 100, 116, and 149 for split sampling with NCDEQ. Sediment samples were collected from the sediment surface to a depth of approximately 4 inches below the sediment surface. The minimum acceptable recovery was two inches of material depth retained in the sampler for a grab sample to be retained for compositing. Multiple grab samples were collected using the specified sampling device to obtain sufficient material to satisfy sample volume requirements as specified in the Characterization Plan (Geosyntec, 2020a). The grab samples were composited together in a decontaminated stainless-steel container and homogenized using a decontaminated stainless-steel spoon prior to filling sample bottles. Large materials present in the sediment (e.g., gravel, vegetation) were avoided when filling sample bottles. Sediment texture and other relevant observations were noted on field forms (Appendix A). Each sampling container was capped, labeled, and stored on ice (4 ± 2°C). Sampling details are provided in Table 1. 3.2.2 Surface Water Sampling Procedures Water column sampling was conducted in general accordance with USEPA SOP SESDPROC-201-R4 Surface Water Sampling (USEPA, 2016a) and the approved Characterization Plan (Geosyntec, 2020a). Water column samples were collected from the mid-channel (“B”) segment of each transect and were collected prior to sediment sample collection at the same segment. Sampling details are provided in Table 2. Sampling depths were selected as described in Section 3.1. A total of 16 surface water samples were collected. Water column samples were collected using a peristaltic pump, new dedicated high-density polyethylene tubing, and new dedicated silicone tubing for the pump head at each sample. The tubing was lowered to the sampling depth using an anchor weight and the fastened tubing was pointed upwards at the tubing intake. Surface water was pumped directly from the submerged tubing through the pump head to a flow-through cell. Field parameters (turbidity, pH, temperature, specific conductance, dissolved oxygen [DO], oxygen/reduction potential [ORP]) were recorded until parameters stabilized (Table 3). The flow-through cell was then disconnected, the end of the tubing previously connected to the flow-through cell was cut off, and grab samples were collected from the discharge of the peristaltic pump into new, laboratory-supplied bottleware. Each sampling container was capped, labeled, and stored on ice (4 ± 2°C). TR0795 6 October 2020 3.3 Analytical Methods Sediment samples were analyzed by the following methods: • PFAS by Method 537M and Table 3+; • Grain size by American Society for Testing and Materials (ASTM) D422-63; • Moisture content by ASTM D2216-90; and • TOC by Lloyd Khan. Water column samples were analyzed by the following methods: • PFAS compounds by Method 537M and Table 3+; • Total suspended solids by ASTM 2540 D-1997; and • Dissolved organic carbon and TOC by SW-846 9060A. Samples were shipped to either Eurofins Lancaster Laboratories, Inc. or TestAmerica Laboratories, Inc. for analysis. 3.4 Sampling Conditions Surface water and sediment sampling was intended to target base flow conditions, and the Work Plan stated sampling would not occur within 72 hours of a rain event. Base flow conditions were further defined as no more than 0.3 inches of cumulative rainfall over the preceding 72 hours3 and a gage height specified at the nearest USGS gage coinciding with typical base flow conditions4. As a result of several rain events which occurred during the sampling schedule, sampling was delayed several times and was conducted over a span of 43 days (Tables 1 and 2); additionally, samples were not always collected sequentially upstream to downstream. The results presented herein should be viewed with the consideration that the samples were collected over this timespan. During the 43 day period, River flow rates ranged from 678 to 26,194 cubic feet per second (cfs); sampling was conducted during flow rates of 3 as measured at the nearest Cape Fear River rain gage. Baseline conditions were monitored according to the USGS website for W.O. Huske Lock (STPN7) and Lock & Dam #1 (CPFN7). Forecasted precipitation for each location was monitored according to the USGS National Water Information System website for W.O. Huske Lock (02105500) and Lock & Dam #1 (02105769). 4 Flow rates used were measured at the nearest gage. The flow rates corresponding to stage heights of approximately 4.5 feet for the W.O. Huske Dam and 17.9 feet at Lock & Dam #1. TR0795 7 October 2020 approximately 700 to approximately 8,900 cfs (Figure 4; Table 4). Sampling dates and other details for each sampling segment are provided in Tables 1 and 2, and a summary of Cape Fear River flow rates is provided in Table 4. 4 SAMPLING RESULTS This section presents results from the sampling activities described in Section 3. Specifically, this section describes data quality regarding data included in this report and then describes the analytical and geotechnical results from the sampling program. 4.1 Data Quality The analytical data were reviewed using the Data Verification Module (DVM) within the Locus™ Environmental Information Management (EIM) system, a commercial software program used to manage data. Following the DVM process, a manual review of the data was conducted. The DVM and the manually reviewed results were combined in a data review narrative report for each set of sample results, which were consistent with Stage 2b of the USEPA Guidance for Labeling Externally Validated Laboratory Analytical Data for Superfund Use (USEPA-540-R-08-005, 2009). The narrative report summarizes which samples were qualified (if any), the specific reasons for the qualification, and any potential bias in reported results (Appendix B). The data usability, in view of the project’s data quality objectives (DQOs), was assessed, and the data were entered into the EIM system. The data were evaluated by the DVM against the following data usability checks: • Hold time criteria; • Field and laboratory blank contamination; • Completeness of quality assurance/quality control samples; • Matrix spike/matrix spike duplicate recoveries and the relative percent differences (RPD) between these spikes; • Laboratory control sample/control sample duplicate recoveries and the RPD between these spikes; • Surrogate spike recoveries for organic analyses; and • RPD between field duplicate sample pairs. A manual review of the data was also conducted, which included a review of instrument-related quality control results for calibration standards, blanks, and recoveries. TR0795 8 October 2020 The data review process (DVM plus manual review) applied the following data evaluation qualifiers to the analytical results as required: • J Analyte present, reported value may not be accurate or precise; • UJ Analyte not present below the reporting limit, reporting limit may not be accurate or precise; and • B Analyte present in a blank sample, reported value may have a high bias. Results are reported in the data validation white book (Appendix B). Following the automated and manual data validation reported in the white book, additional manual validation was conducted: • Chromatograms for all analytes in all field samples were reviewed for peak shape and retention time against the peak shape and retention time of the appropriate standards; • Calibration for PMPA and PFMOAA were verified (recalculated); • Approximately 10% of the PMPA and PFMOAA detections in the field samples were verified (recalculated); • Non-detects for all compounds were verified via visual examination of the chromatograms. This additional manual validation revealed no further data quality issues. The DQOs were met for the analytical results for accuracy and precision. The data collected are believed to be complete, representative and comparable, with the exception of three compounds: R-PSDA, Hydrolyzed PSDA, and R-EVE. As reported in the Matrix Interference During Analysis of Table 3+ Compounds memorandum (Geosyntec, 2020b), matrix interference studies conducted by the analytical laboratory (TestAmerica Laboratories, Inc., Sacramento) have shown that the quantitation of these three compounds (R-PSDA, Hydrolyzed PSDA, and R-EVE) is inaccurate due to interferences by the sample matrix, and that the interference results in over-estimation of these concentrations. Consequently, all results above the reporting limit for R-PSDA, Hydrolyzed PSDA, and R-EVE in the sediment and surface water results have been J- qualified as estimated. Given the matrix interference issues, Total Table 3+ PFAS concentrations are calculated and presented two ways in this report: (i) summing over 17 of the 20 Table 3+ compounds “Total Table 3+ (sum of 17 compounds)”, i.e., excluding results of R-PSDA, Hydrolyzed TR0795 9 October 2020 PSDA, and R-EVE, and (ii) summing over 20 of the Table 3+ compounds “Total Table 3+ (sum of 20 compounds)”. Expressing these data as a range represents possible values of what these results might be without matrix interferences. In other words, the sum of the 17 compounds is an underestimate of the actual value while the sum of the 20 compounds is likely an overestimate of the actual value. HFPO-DA can be analyzed by either Method 537M or by the Table 3+ Method. The laboratory selects the method depending on their current analyte lists; results from both methods are considered accurate and comparable. For this sample set, HFPO-DA was analyzed in some samples by Method 537M and in some samples by both methods. If HFPO-DA was measured by both methods, the reported concentration was determined as follows: the higher concentration was reported when both results were detected above reporting limits; the detected value was reported when one result was detected and the other was a not detected above reporting limits, and; the lower reporting limit was reported when both results were not detected above reporting limits. In this Report, regardless of the method used for analysis, HFPO-DA is grouped with Table 3+ compounds for totaling concentrations in tables and figures in order to be consistent with past reports. 4.2 Analysis of Cape Fear River Sediment Samples collected in this program were intended to be collected during baseline conditions (see Section 3.4), and as a result, samples were collected over approximately six weeks. The Cape Fear River flow varied during the sampling period (Figure 4). Sampling dates, flow conditions, concentrations at each segment, and surface water mass discharge are provided in Table 3. Sampling results are provided in Tables 5A, 5B, and 5C. 4.2.1 Geotechnical Properties in Sediment Sediment samples ranged from 97% coarse grained (sand + gravel fractions), at the mid- channel segment at River Mile 76 to 11% coarse grained (89% fine grained) in the secondary channel where River Mile 149 was collected (“C” segment; Table 5C). In general, samples collected in the mid-channel segments contained coarser grained material than samples collected along bank (“A” and “C”) segments. TOC ranged from below the reporting limit at mid-channel segments at River Mile 77 and River Mile 132 to 33,000 mg/kg at River Mile 116 (“C” segment). TOC was generally observed to be higher in bank (“A” and “C”) segment samples than in mid-channel (“B”) segment samples (Table 5C). Transects with the highest TOC content (River Miles 76, TR0795 10 October 2020 77, and 149) were also the transects with the highest fines contents (River Miles 76, 77, 84, and 149). 4.2.2 Cape Fear River Table 3+ PFAS in Sediment Of the nine transects sampled, Table 3+ compounds were detected above reporting limits in sediment samples from three transects: River Miles 76 and 77, which are adjacent to the Site, and River Mile 149, which is downstream of the Site (Figure 5). The highest concentrations of Table 3+ compounds were found in sediment samples from River Mile 77. Table 3+ compounds were not detected above reporting limits in sediment upstream from the Site or in any mid-channel sample from any transect. The concentrations of Total Table 3+ (20 or 17 compounds) ranged from below the reporting limits in several samples to a maximum concentration of 18.4 micrograms per kilogram (µg/kg) at River Mile 77 (“A” segment, collected on the western riverbank, alongside the facility). The highest individual compound concentration was perfluoro-2-methoxyaceticacid (PFMOAA) at 9.9 µg/kg from the sample collected at River Mile 149 (“C” segment). In total, eight of the 20 Table 3+ compounds (including HFPO-DA) were detected above reporting limits in samples from this event (Table 5A). The distribution of PFAS in sediment is further discussed in Section 5. 4.2.3 Cape Fear River Method 537M PFAS in Sediment In contrast to Table 3+ compounds, Method 537M compounds were detected above reporting limits in samples from each of the nine transects sampled including areas upstream of, adjacent to, and downstream of the Site. The highest total concentration was detected at River Mile 149 (Figure 5). Generally, Method 537M concentrations were lower or not detected above the reporting limit in mid-channel (“B”) segments. The total concentrations of Method 537M PFAS ranged from below the reporting limits in several samples to a maximum concentration of 33.36 µg/kg at River Mile 149 (“C” segment). The greatest number of Method 537M PFAS detected above reporting limits at a segment was 17 compounds, from River Mile 76 (“A” segment); River Mile 76 is adjacent to the Site and downstream of the city of Fayetteville and the farther upstream location RM-52 (Figure 3c). The most frequently detected above reporting limits and highest measured Method 537M PFAS was 2-(N-ethyl perfluoro-1-octanesulfonamido)-ethanol found both upstream and downstream of the Site. It was detected above reporting limits in 22 of the 32 sediment samples analyzed and it was detected in at least one segment along each transect, including upstream of, adjacent to, and downstream of the Site. The highest detection was TR0795 11 October 2020 at River Mile 100 “C” segment (opposite the Elizabethtown WWTP) at 15 µg/kg (Table 5B). In total, 19 of the 35 Method 537M compounds were detected above reporting limits in samples collected from this event (Table 5B). The distribution of PFAS in sediment are further discussed in Section 5. 4.3 Analysis of Cape Fear River Surface Water Samples collected in this program were intended to be collected during baseline conditions (see Section 3.4), and as a result, samples were collected over a span of 43 days. The Cape Fear River flow varied during the sampling period. Sampling dates, flow conditions, and concentrations at each segment are provided in Table 2 and Figure 4. Sampling results are provided in Tables 6A, 6B, and 6C. Samples were collected at two depths in seven of the nine transects (as described in Section 3.1). Table 3+ concentrations were similar between the two sampling depths (Table 6A). 4.3.1 Cape Fear River Table 3+ PFAS Sampling Results Table 3+ PFAS were detected above the reporting limit in all surface water samples collected during the sampling program, spanning from River Mile 20 through River Mile 149. Concentrations varied by River Mile (Figure 6a). However, mass discharge is greater downstream of the Site, as shown in Figure 6b. Results are listed in Table 6A. Fewer Table 3+ compounds were detected above the reporting limit in the samples collected upstream of the Site relative to samples collected downstream. Analytes detected above reporting limits in upstream samples were limited to three compounds5; the analytes detected above reporting limits in downstream samples ranged from six to 10 compounds, with several compounds6 found in every downstream sample. The concentrations of Total Table 3+ (17 and 20 compounds) ranged from 2.4 nanograms per liter (ng/L) at River Mile 77 (18 feet below water surface) to a maximum concentration of 131 ng/L at River Mile 100 (17 feet below water surface). The highest individual Table 3+ compound concentration was perfluoromethoxypropyl carboxylic acid (PMPA) at 42 ng/L from the sample collected at River Mile 100 (17 feet below water 5 Perfluoromethoxysulfonic Acid [NVHOS], perfluoromethoxypropyl carboxylic acid [PMPA], and Ethanesulfonic acid, 1,1,2,2-tetrafluoro-2-[1,2,2,3,3-pentafluoro-1-(trifluoromethyl)propoxy] [R-PSDA] 6 HFPO-DA, Perfluoro-2-methoxyaceticacid [PFMOAA], Perfluoro(3,5-dioxahexanoic) Acid [PFO2HxA], Perfluoro(3,5,7-trioxaoctanoic) Acid [PFO3OA], and 1,2,2,3,3-pentafluoro-1-(trifluoromethyl)propoxy [Hydrolyzed PSDA] TR0795 12 October 2020 surface). In total, 10 Table 3+ compounds (including HFPO-DA) were reported in samples from this event (Table 6A). The distribution of PFAS in surface water are further discussed in Section 5. 4.3.2 Cape Fear River Method 537M PFAS Sampling Results Method 537M were detected above the reporting limit in all surface water samples collected during the sampling program, spanning from River Mile 20 through River Mile 149. Several Method 537M compounds were detected in relatively consistent concentrations above the reporting limit in the surface water samples from River Mile 20 through River Mile 149 (Figure 6a). Results are listed in Table 6B. Compounds detected above the reporting limit were Perfluorobutane Sulfonic Acid, Perfluorobutanoic Acid, Perfluoroheptanoic Acid, Perfluorooctanoic Acid (PFOA), and Perfluorooctane Sulfonate (PFOS). There were no other Method 537M compounds detected above reporting limits. Total Method 537M compounds ranged from 48.5 ng/L at River Mile 149 (1.5 feet below water surface) to a maximum concentration of 72.5 ng/L at River Mile 52 (1.6 feet below water surface). The highest individual Method 537M compound concentration was PFOS at River Mile 84 (18 feet below water surface) at 15 ng/L (Table 6B). PFOS is not produced or used at the Site or present in Site process water samples (Chemours, 2019; Geosyntec, 2019f). The distribution of PFAS in surface water are further discussed in Section 5. 5 DISCUSSION Along its course, the Cape Fear River receives contributions from a variety of sources which have associated PFAS discharges, including the Little River, various creeks, direct groundwater discharge to the Cape Fear River, and discharges from multiple POTWs and industrial dischargers (NCDEQ, 2020; PFAST Network, 2020). Between River Miles 76 and 77, there are several Site-related inputs into the Cape Fear River which have also been identified as sources of PFAS to the River7. The Cape Fear River then transports dissolved-phase chemicals from these inputs (Geosyntec, 2020c) and also transports and, subsequently deposits, sediments suspended in the water column. 7 Site-related impacts include Willis Creek, onsite Seeps, Old Outfall 002, and onsite groundwater, all of which have been identified as transport pathways of PFAS to the Cape Fear River (Geosyntec, 2019a, 2019b, 2020e) TR0795 13 October 2020 This section presents a summary of the Cape Fear River sediment grainsize data, a discussion of the distributions of Table 3+ and Method 537M PFAS detected in sediment samples and surface water samples, and a contextualization of the results of this program relative to the 2019 Human Health and Ecological Screening Level Exposure Assessments (Geosyntec, 2019a). 5.1 Cape Fear River Sediment Grainsize and TOC Data The distribution of riverbed sediments in the Cape Fear River is a product of the underlying geology, sediment load inputs, and water velocities in the Cape Fear River. Water generally flows fastest in the thalweg (i.e., the deepest point of river cross section) and is a function of channel slope (i.e. gradient of the river), channel width, and flow, which results in higher water velocities in areas with steeper terrain or a narrower channel and lower water velocities in flatter-areas or areas with a wider channel. Where water carrying suspended sediment moves from a high-velocity environment to a lower-velocity environment, sediment is often deposited, and erosion is less likely to occur. Samples collected during this program indicate a higher relative percentage of fine-grained material is distributed along the banks of the Cape Fear River (“A” and “C” segments) compared with the center channel (Figure 7a). Consistent with expected river dynamics, faster currents in the center channel appear to prevent finer grained sediment accumulation in the center channel sections of the Cape Fear River. The transect segment with the highest proportion of silts and clays (i.e., fine grained material) sampled in this program was at River Mile 149 (“C” segment bank sample; Figure 7a, Table 5C). The proportion of fines (combined clay and silt fractions of 89%) found in this area of River Mile 149 suggests that this is a depositional environment. The River Mile 149 transect is off the main channel of the River in a secondary flow channel that likely experiences lower water velocities. Bathymetry data from the US Army Corps of Engineers indicates the slope of the Cape Fear River Channel is essentially zero for six miles upstream and five miles downstream of this sampling transect, which will reduce water velocities in this area. Additionally, water velocities in this reach of the Cape Fear River are expected to be further reduced due to backwater effects from strong tidal currents nearer the mouth of the Cape Fear River (Bowen et. al, 2009). All of these factors contribute to the depositional environment at this location. Riverbank samples from River Miles 76, 77, and 84 also contained relatively elevated proportions of fines (over 60%). Transects at River Miles 76 and 77 are upstream of and TR0795 14 October 2020 potentially influenced by the W.O. Huske Dam; the Dam may create areas of lower water velocity upstream of the Dam in which suspended sediments may deposit. TOC content in Cape Fear River sediments is generally correlated with finer sediment grain sizes (Figure 7b); this is consistent with expectations, as TOC is often associated with finer particulates (Horowitz, 1991). TOC was observed to be higher in bank (“A” and “C”) segment samples than in mid-channel (“B”) segment samples (Figures 7b and 7c). Transects with the highest TOC content (River Miles 76, 77, and 149) were also the transects with the highest fines content (Figure 7c). Contaminants in river systems are more likely to be found in finer-grained, higher organic content sediment than in sediment which is coarser grained with lower organic content (ITRC, 2014). This association is due to contaminants preferentially adsorbing to finer grained sediments, often the TOC component, which makes TOC and grain size distribution potential indicators of areas of sediment impacts (ITRC, 2014). Literature suggests that PFAS compounds, especially longer-chained PFAS, have a greater potential for adsorption to particulate matter in the environment (Kucharzyk et al, 2017). 5.2 Table 3+ and Method 537M PFAS Distribution in Sediment Table 3+ PFAS were detected above reporting limits at three of the nine sampling transects: River Miles 76 and 77, which are adjacent to the Site, and River Mile 149, which is downstream of the Site. Table 3+ compounds were only detected above reporting limits in bank samples. As noted in Section 5.1, River Miles 76 and 77 may have some depositional areas due to influences of the W.O. Huske Dam, and River Mile 149 is expected to be depositional environment. Upstream of the Site, transects at River Miles 20 and 52 were in areas with coarser grained sediment which are not expected to be depositional areas. Eight individual Table 3+ PFAS were detected above reporting limits from the bank (“A” and “C”) segments at the transects at River Miles 76 and 778. At the River Mile 76 sampling transect, Table 3+ PFAS were detected above reporting limits in both “A” and “C” bank segments with the higher concentration from the western shore (Site-adjacent) sample (segment “A”); the Total Table 3+ PFAS at segment “A” was 15.9 µg/kg; at segment “C”, the Total Table 3+ concentration was 5.9 µg/kg. At River Mile 77, 8 Compounds detected above reporting limits were HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PFO5DA, PMPA, PS Acid. TR0795 15 October 2020 Table 3+ PFAS were only detected above reporting limits in the western shore segment (“A”) with a total concentration of 18.4 µg/kg. Table 3+ PFAS were not detected above the reporting limit in samples from the next four downstream transects (River Miles 84, 100, 116, and 132). Table 3+ PFAS were detected above reporting limits in one bank segment at River Mile 149 (“C” segment) with a maximum concentration among the three samples collected at this segment of 13.64 µg/kg. In contrast to Table 3+ PFAS, Method 537M PFAS compounds were detected above reporting limits in samples from each of the nine transect sampled, including areas upstream of, adjacent to, and downstream of the Site. The highest concentration sample was at River Mile 149, segment “C”, at 33.36 µg/kg. This is the same sample location which had downstream detections of Table 3+ PFAS above reporting limits, further confirming the depositional nature of this segment. The segment with the greatest number of Method 537M PFAS was River Mile 76, segment “A” with 17 compounds detected above reporting limits followed by River Mile 76, segment “C”, and River Mile 77 segment “C” both with 11 compounds detected above reporting limits. As noted earlier, River Miles 76 and 77 are potentially located in a depositional environment, particularly compared to the next upstream location at River Mile 52 where far fewer fines were present in the sediment samples. Upstream watershed data from POTWs and industrial discharges (NCDEQ, 2020) and upstream watershed water data collected by the PFAST Network (2020) indicate that all the compounds detected in sediment at River Miles 76 and 77 were positively identified in upstream samples with the exception of two compounds, which were not analyzed in the referenced assessments9. These detections are consistent with known patterns of PFAS contamination to watersheds and upgradient source types such as wastewater treatment plants, landfills, and releases of firefighting foams (ITRC, 2020; Hu et al., 2016). These upstream detections suggest the potential for deposition and accumulation of these compounds in the more depositional environments of River Miles 76 and 77. 5.3 Table 3+ and Method 537M PFAS Distribution in Surface Water Sampling during this program was intended to target base flow conditions, as noted in Sections 3.4 and 4.3. Due to the weather conditions during the sampling schedule, 9 The two compounds not quantitated in upstream samples collected by NCDEQ or the PFAST Network were 2-(N-ethylperfluoro-1-octanesulfonamido)-ethanol and 2-(N-methylperfluoro-1-octanesulfonamido)-ethanol. TR0795 16 October 2020 sampling was delayed several times and was conducted over a span of 43 days (Tables 1 and 2). During this time, the flows in the Cape Fear River varied considerably (Figure 4; Table 4). Variation in flow directly affects the concentrations of PFAS measured in samples, as a large fraction of the Table 3+ PFAS mass load in the Cape Fear River comes from onsite transport pathways which are unaffected by River stage (Onsite Seeps and Old Outfall 002 [Geosyntec, 2020d]). These PFAS loads will then mix in the Cape Fear River and final concentrations will be a factor of the volume of water present in the River. More water in the Cape Fear River (i.e., higher River flows) will lead to lower PFAS concentrations. Table 3+ PFAS were detected above the reporting limit in the surface water samples collected during the sampling program, spanning from River Mile 20 through River Mile 149 (Table 6A). Table 3+ analytes PFAS PMPA, perfluoromethoxysulfonic acid (NVHOS), and R-PSDA were detected above reporting limits in transects located at River Miles 20, 52, and 76. Beginning at River Mile 77 and continuing downstream, a greater number of Table 3+ PFAS compounds were detected above reporting limits in surface water samples. While concentrations varied by River Mile (Figure 6a), the mass discharge of well-mixed Cape Fear River samples downstream of the Site (i.e., River Mile 84 to River Mile 149) was relatively constant (between 7 and 10 milligrams per second for 17 Table 3+ compounds; between 8 and 11 mg/s for 20 Table 3+ compounds), with the exception of one measurement with a higher value at River Mile 116 (Table 4; Figure 6b). The sample collected at River Mile 77 had the lowest concentration and second lowest calculated mass discharge over the sampling program (Figures 6a and 6b). The lower concentrations and mass load at River Mile 77 may be related to incomplete mixing of the Cape Fear River directly adjacent to the Site; inputs from the Site are not fully mixed into the Cape Fear River until further downstream nearer River Mile 81 (Figure 8) . Similar to past investigations (Geosyntec 2018, 2020c), Method 537M compounds were detected above the reporting limit throughout the length of the sampled Cape Fear River. These compounds have been detected above reporting limits in past sampling events in the Deep and Haw Rivers which meet to form the Cape Fear River (Geosyntec, 2018, 2020c). Consistent with past sampling results, Method 537M concentrations remained relatively constant directly upstream, adjacent to and downstream of the Site (Figure 6a; Figure 9). TR0795 17 October 2020 5.4 Comparison of Sediment Results to Human Health and Ecological Screening Level Exposure Assessments The information and results of the 2019 SLEA (Geosyntec, 2019a) were used to provide context for the newly collected PFAS data with respect to potential human and ecological hazards. As discussed in the SLEA (Geosyntec, 2019a), the lack of available toxicity information inhibits the full quantification of potential risks for the majority of Table 3+ PFAS. Sufficient toxicity information is available only for HFPO-DA to perform hazard characterization. The data collected to support the Sediment Characterization were not intended to provide a revised hazard characterization in the Human Health or Ecological components of the Screening Level Exposure Assessment (HHSLEA and Eco-SLEA; SLEA, Geosyntec 2019a). Also of note, the extent of the Sediment Characterization along the Cape Fear River was more expansive than that applied in the 2019 Screening Level Exposure Assessment (SLEA, Geosyntec 2019a). 5.4.1 Data Comparison: Human Health SLEA Overall, the surface water data from this program exhibit lower associated concentrations of HFPO-DA when compared with data underpinning the 2019 SLEA. Differences between the assessment discussed here and the 2019 SLEA are that first, fish tissue sampling was not part of this sampling program, so no new data were available. The second difference is that this evaluation also considers direct contact with sediment as a line of evidence for understanding human health components. In light of available data, this comparative assessment focuses on surface water exposures, with an ancillary consideration for sediment and fish complete exposure pathways. The following notes describe how this comparison was performed: • Data collected from this program at River Mile 52 were compared to data underpinning SLEA Exposure Unit (EU) 13, representing conditions upgradient from the facility, based on Cape Fear River flow; • Data collected from this program at River Miles 76 and 77 were compared to data underpinning SLEA EU14, representing River conditions adjacent to the facility; • Data collected from this program at River Mile 84 were compared to data underpinning SLEA EU16, in an assessment of downgradient conditions at the Bladen Bluffs surface water intake; and TR0795 18 October 2020 • Data collected from this program River Mile 132 were compared to data underpinning SLEA EU17, in an assessment of far downgradient conditions at the Kings Bluff surface water intake. • Data collected from River Miles 20, 100, 116 and 149 represent investigation areas not previously assessed within the context of the SLEA. Surface Water Surface water data collected during this program generally exhibit an order of magnitude lower level of HFPO-DA than the data used in the 2019 SLEA (Table 7). In the 2019 SLEA, the reasonable maximum exposure (RME)-based exposure point concentration (EPC) represents either an upper-bound estimate on the mean or the maximum detected concentration (Table 7). In recognition of dynamic conditions in a river, including fluctuating flow volumes and flow rates as well as sediment and suspended particle loading, the preferred metric for this comparison is the central tendency exposure (CTE)-based EPC, which reflects the dataset mean. In an assessment of the CTE EPCs, the trends in comparison between the surface water data sets from this program and the 2019 SLEA are consistent, with the more recent data reflecting an order of magnitude lower HFPO-DA concentration. In a refinement of the assessment outlined above, comparing the 2019 SLEA total dataset with the corresponding data from this program, the SLEA dataset was queried to isolate only data from the 2019 sampling year. Based on this comparison, the surface water data from this program still represent a substantive decrease in recorded HFPO-DA concentrations in Cape Fear River surface water, with the concentrations from this program reported as less than half those associated with the 2019 data averages (in corresponding EUs) (Table 7). Combined concentrations of PFOA and PFOS in surface water from all locations sampled in this program were below the 70 ng/L USEPA Lifetime Health Advisory level (USEPA, 2016b, 2016c). Combined PFOA and PFOS concentrations ranged from 17.8 ng/L (River Mile 20) to 22.2 ng/L (River Mile 84). Concentrations of HFPO-DA were below the 140 ng/L HFPO-DA provisional health goal (NCDEQ and NCDHHS, 2018). Surface water HFPO-DA concentrations ranged from below reporting limits to 15 ng/L (River Mile 100). HFPO-DA was only reported in samples downstream of the Fayetteville Works facility. TR0795 19 October 2020 HHSLEA – Sediment Sediment data collected during this program are summarized for HFPO-DA and are presented in Table 8. HFPO-DA was detected above reporting limits in only three transects. HFPO-DA was detected above reporting limits in three of four samples from River Mile 76 and one of three samples from River Mile 77, both transects are considered facility-adjacent. The highest reported transect-specific EPC HFPO-DA occurred at River Mile 77 at a concentration of 2.5 µg/kg. HFPO-DA was also detected above reporting limits downstream at River Mile 149 in one of five samples, at a maximum detected concentration of 0.34 µg/kg , a value nearly an order of magnitude less than the levels associated with the facility-adjacent transects. HHSLEA – 2020 Data Impact on Risk Characterization As discussed in the SLEA (Geosyntec, 2019a), the lack of available toxicity information inhibits the full quantification of potential risks for the majority of Table 3+ PFAS. Neither surface water nor sediment exposures to HFPO-DA, based on conditions assessed in the 2019 SLEA or based on data from this program, contribute unacceptable exposures to relevant human populations based on the USEPA target hazard index. Complete exposure pathways associated with these contact media are several orders of magnitude below the driving pathways of concern. Recreational user direct contact with sediment was not a component of the complete exposure pathways in the human health component of the 2019 SLEA and fish tissue data were not collected in this program. Surface water data results were the line of evidence supporting an assessment of potential impact on the 2019 SLEA outcomes. Surface water data collected in this program are associated with HFPO-DA concentrations that are lower than surface water concentrations evaluated in the 2019 SLEA. The findings of the SLEA did not indicate excess hazard levels for the maximally exposed population (e.g., recreational child) and the reduced concentrations evident in the data from this program suggest even lower associated hazard. In the 2019 SLEA, recreational population direct contact hazards associated with HFPO-DA in Cape Fear River surface water were greatest for a child recreator. Associated child recreator hazard was greatest at EU16, where fish tissue data were available to support consumption exposure; however, surface water exposure-alone for this population, based on HFPO-DA, was greatest in EU14, adjacent to the site. In EU14, RME-child recreator hazard based on surface water direct contact was calculated to be 4.8E-04, a value roughly 4 orders of magnitude below USEPA’s target hazard quotient of unity and the threshold to define unacceptable exposure. Based on lower recorded TR0795 20 October 2020 HFPO-DA level results in surface water data from this program, associated hazard for a child recreator is projected to be lower, approximately 2.7E-05. The highest recorded concentration of HFPO-DA in the sediment dataset from this program occurred at River Mile 77, with a concentration of 2.5 µg/kg. Presuming consideration of recreational parameter values consistent with a child recreator (e.g., 12 days/year, body weight of 15 kg, exposure duration of 6 years) in combination with a conservative sediment incidental ingestion rate consistent with residential soil (i.e., 200 mg/day), associated HFPO-DA hazard is approximately 1.1E-05. At River Mile 77, the total surface water and sediment hazard attributable to a recreational child is approximately 3.8E-05, a value more than 10,000 times lower EPA’s hazard threshold of one. Fish tissue data were not collected at River Mile 77 (coincident with EU14); however, if recreational child fish tissue hazard (0.1) is taken from River Mile 86 (coincident with EU16), and added to the updated surface water (2.7E-05) and sediment (3.8E-05) hazards calculated for River Mile 77, cumulative hazard for HFPO-DA is 0.1, a value equal to the highest projected hazard for this population in the 2019 SLEA and below EPA’s hazard threshold of one. 5.4.2 Ecological SLEA Data Comparison PFAS Profiles The profile of Table 3+ PFAS detected above reporting limits in surface water in this program was similar to those detected above reporting limits in the Eco-SLEA dataset in 2019. PEPA was newly detected above reporting limits in the sediment characterization program surface water samples, but R-EVE was not detected above reporting limits, having been previously detected above reporting limits in the SLEA dataset (Table 9). In the Eco-SLEA dataset, only HFPO-DA had been detected above reporting limits in the surface sediment samples collected adjacent to the facility (n = 6). Additional Table 3+ PFAS were detected above reporting limits in sediment samples from this program (Table 9). Many of the Table 3+ PFAS detected above reporting limits in sediment that were not previously detected above reporting limits are consistent with those previously detected above reporting limits in fish, including PFOMAA, perfluoro(3,5,7,9-tetraoxadecanoic) acid (PFO4DA), perfluoro-3,5,7,9,11-pentaoxadodecanoic acid (PFO5DA), PMPA, and R-EVE. However, perfluoro(3,5-dioxahexanoic) acid (PFO2HxA), perfluoro(3,5,7-trioxaoctanoic) acid (PFO3OA), and phosphatidylserine (PS Acid) have been detected above reporting limits in sediment samples from this program but were not TR0795 21 October 2020 detected above reporting limits in fish samples from the 2019 Eco-SLEA. The relative uptake of PFAS from sediment versus surface water for various fish species is not well understood at this time. Potential Hazard from HFPO-DA Exposures Concentrations of HFPO-DA were generally consistent with those included in the Offsite Aquatic EU of the SLEA (maximum concentration in the SLEA dataset was also 15 ng/L HFPO-DA). This program covered a larger area than the Aquatic EU in the Eco-SLEA; concentrations of HFPO-DA in surface water samples from within this EU (River Miles 76 and 77) are significantly lower in comparison with data in the SLEA (2.2 ng/L vs. 15 ng/L). These concentrations are orders of magnitude below the Probable No Effect Concentrations for aquatic-life exposure to HFPO-DA (108,000 ng/L) and do not suggest aquatic-life risks due to HFPO-DA. Even the highest concentration of Total Table 3+ PFAS (130 ng/L) are well below this benchmark. Concentrations of HFPO-DA in sediments were also consistent between the Eco-SLEA and this program and are well below the available benchmarks for benthic toxicity (518 µg/kg dry weight). Hazard quotients (HQs) for aquatic wildlife in the Eco-SLEA ranged from 0.018 to 0.0000018 for HFPO-DA; indicating daily exposures lower by more than 10 to 100,000 times the available toxicity benchmarks for HFPO-DA. Given the similar range of concentrations in both sediment and surface water, these new data do not indicate a potential for wildlife risks from HFPO-DA. Table 3+ PFAS as a Component of Total PFAS As discussed in the Eco-SLEA (2019), a number of recent studies have evaluated the presence of both Tale 3+ PFAS and non-site associated PFAS (primarily perfluoroalkyl acids) in biota in the Cape Fear River Estuary (Robuck et al. 2019; Guillette et al. 2019). These studies found that in shore birds, Striped bass, and American alligators, PFOS was the predominant PFAS in tissue samples. The sediment data also support that PFOS is widely detected above reporting limits in sediment, resulting in bioaccumulation in the Cape Fear River food web. The current understanding of relative bioaccumulation potential indicates that PFOS continues to be one of the most bioaccumulative of the PFAS studied (Conder et al. 2020) indicating that it will likely to remain an ecological risk-driver in the Cape Fear River system. TR0795 22 October 2020 6 SUMMARY Surface water and sediment samples were collected from nine transects along the length of the Cape Fear River in May and June 2020. These samples were collected to evaluate the nature and extent of PFAS upstream of, adjacent to, and downstream of the Site in the Cape Fear River. Across the sampling program, a higher relative percentage of fine-grained material was located in riverbank sediment samples compared with the mid-channel samples, consistent with expected river dynamics where banks with lower water velocities are more depositional. Sediment sampling locations with higher fines contents were also associated with higher TOC contents. Contaminants preferentially adsorb to finer grained sediments, often the TOC component, which makes TOC and grain size distribution indicators of areas with potential sediment impacts (ITRC, 2014). The sediment sample with the highest fines content was observed in a bank sample at River Mile 149. This transect is off the main channel of the River in a secondary flow channel that likely experiences lower water velocities. Bank samples from River Miles 76 and 77 also contained relatively elevated proportions of fines (over 60%), possibly due to their location upstream of the W.O. Huske Dam, which may create areas of lower water velocity upstream of the Dam in which suspended sediments deposit. These two transects are downstream of the city of Fayetteville and adjacent to the Site, and the banks of these transects indicate more depositional conditions than upstream bank sampling locations. Table 3+ PFAS were detected above reporting limits in sediment from the riverbanks at these areas that appear to be depositional with higher fines contents: River Miles 76 and 77, which are adjacent to the Site, and River Mile 149, which is downstream of the Site. Across the sampling program, Method 537M compounds were detected in sediment from all nine sampled transects. All of the Method 537M compounds detected in sediment at River Miles 76 and 77 were positively identified in upstream aqueous samples collected by NCDEQ and the PFAST Network, with the exception of two compounds, which were not analyzed in the referenced assessments (NCDEQ, 2020; PFAST Network, 2020). Detected compounds are consistent with known patterns of PFAS contributions to watersheds from upgradient sources such as effluent from wastewater treatment plants, leachate from landfills, and releases of firefighting foams (ITRC, 2020; Hu et al., 2016). The fraction of total PFAS (Method 537M and Table 3+ combined) comprised of Table 3+ compounds in sediment is approximately 40% at River Miles 76 and 77, and 29% at River Mile 149. TR0795 23 October 2020 Table 3+ PFAS were detected in surface water above reporting limits at each sampling transect. Concentrations generally vary based on the flow of the Cape Fear River, resulting in a relatively constant mass discharge downstream of the Site. Method 537M PFAS were detected above reporting limits in surface water samples along the length of the Cape Fear River. The total concentration of Method 537M PFAS did not change meaningfully upstream or downstream of the Site. The sediment and surface water samples collected in this program were evaluated and compared to data collected and interpretations made in the 2019 Human Health and Ecological SLEAs. The results of this program are consistent with the findings of the SLEAs that, based on presently available information for HFPO-DA exposures quantified, there are no anticipated hazards to human or ecological receptors from exposures to HFPO-DA in surface water or sediment. Concentrations of HFPO-DA were below the 140 ng/L HFPO-DA provisional health goal (NCDEQ and NCDHHS, 2018). Additionally, in the Cape Fear River, the combined concentrations of PFOA and PFOS (Method 537M) in surface water from all locations sampled in this program were below the 70 ng/L USEPA Lifetime Health Advisory level (USEPA, 2016b, 2016c).

Sample Receipt The following items are noted for this data set: • All samples were received in satisfactory condition and within EPA temperature guidelines on: May 21 - 22, 2020 June 11 - 13, 2020 July 2, 2020 Data Review The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process. Overall the data is acceptable for use without qualification, except as noted below: ADQM Data Review Narrative - FAY Sed Char Sampling update2.doc 2 of 3 • The laboratory reported HFPO-DA from both the 537 Modified and Table 3+ analysis for each sample. The best value field was populated to report the “better” result for each sample according to the following criteria: o The higher concentration of two detects was reported. o The detected value was reported when a detect and a non-detect result were evaluated. o The lower reporting limit was reported when two non-detect results were evaluated. • The R-EVE result for sample FAY-SED-RM149-C-063020-D (320-62363-8) was revised by the laboratory to show a non-detect result as the original result was a false positive. A revised lab report was received from the laboratory. • Professional judgement was used to overwrite R qualifiers, indicating an unusable result, that were assigned by the DVM due to a very poor surrogate (isotope dilution analyte or IDA) recovery, and preparation or analysis hold time that was exceeded by more than two times. The qualifier was updated to UJ, indicating an estimated reporting limit, because the target compounds are generally recognized to be stable for an extended time period. In the case of the IDA recovery, data quality is not considered affected by the laboratory if the IDA signal-to-noise ratio is greater than 10:1, which was achieved for all IDA in the samples. • Results for HFPO-DA in one water sample and TSS in three water samples were qualified B and the reported results may be biased high, or false positives, due to comparable concentrations found in associated equipment rinsate or laboratory method blanks. • The laboratory applied an I qualifier to indicate where the transition mass ratio for the indicated analyte was outside of the established ratio limit. The qualitative identification of the analyte has some degree of uncertainty. However, analyst judgement was used to positively identify the analyte and the reviewer applied a J validation qualifier, indicating that the associated result should be considered to be an EMPC (estimated maximum possible concentration). • Due to uncertainty from observed matrix effects during the analysis of R-PSDA, Hydrolyzed PSDA and R-EVE, a J-qualifier has been added to all positive results in the data set, if not already qualified by the DVM and even if there was no matrix spike analyzed for that particular sample, and the results should be considered to be estimated values. • Analytical results have been qualified J as estimated, and non-detect results qualified UJ indicating an estimated reporting limit, due to a poor surrogate or matrix spike recovery; sample preparation or analysis which exceeded the laboratory established hold time; and poor field duplicate or lab replicate precision. See the Data Verification Module (DVM) Narrative Report for which samples were qualified, the specific reasons for qualification, and potential bias in reported results. • The non-PFAS results for samples were reported by the laboratory to the method detection limit (MDL); results reported between the MDL and the practical quantitation limit (PQL) are qualified J and are considered to be estimated values.

The lab reports due to a large page count are stored on an AECOM network shared drive and are available to be posted on external shared drives, or on a flash drive. ADQM Data Review Narrative - FAY Sed Char Sampling update2.doc 3 of 3 Data Verification Module (DVM) The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks: • Field and laboratory blank contamination • US EPA hold time criteria • Missing Quality Control (QC) samples • Matrix spike(MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences (RPDs) between these spikes • Laboratory control sample(LCS)/control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • RPD between field duplicate sample pairs • RPD between laboratory replicates for inorganic analyses • Difference / percent difference between total and dissolved sample pairs. There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample. J Analyte present. Reported value may not be accurate or precise. UJ Not detected. Reporting limit may not be accurate or precise. The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank. If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier. DVM Narrative ReportContamination detected in equipment blank(s).
