(Geosyntec) has prepared this 2020 Onsite and Offsite Groundwater Report for The Chemours Company, FC, LLC (Chemours) to present the results of the 2020 Annual Onsite and Offsite Groundwater event performed during the third quarter 2020 at and around the Site. Chemours operates the Chemours Fayetteville Works facility in Bladen County, North Carolina (the Site). This sampling event and report were conducted pursuant to the Performance Monitoring section of the Corrective Action Plan (CAP; Geosyntec, 2019a) which specified three annual groundwater sampling events of Chemours-installed wells onsite and offsite occur during the third quarter of years 2020, 2021 and 2022 with reports being provided by the end of the first quarter of the following year (i.e. March 31st). After the third annual event (2022) the annual groundwater monitoring report will evaluate if changes should be made to the sampling program such as adding/reducing the number of wells sampled or abandoning certain wells. The data collected during the 2020 Annual Onsite and Offsite Groundwater sampling event were used to assess groundwater concentrations of Total Table 3+ per- and polyfluoroalkyl substances (PFAS) in the onsite and offsite groundwater wells at and surrounding the Site. Table 3+ PFAS is a term used to refer to PFAS predominantly related to Site manufacturing operations for which analytical methods exist (Table 1) and presently, the grouping of PFAS referred to as Table 3+ are analyzed by the Table 3+ standard operating procedure (SOP) analytical method. This report is intended to supplement the baseline and reduction monitoring programs outlined in the Corrective Action Plan (CAP; Geosyntec, 2019a) as required under Paragraphs 16(c) and (d) of the executed Consent Order (CO) dated 25 February 2019 among the North Carolina Department of Environmental Quality (NCDEQ), Cape Fear River Watch. There were no significant changes in groundwater flow velocities across the Site and the PFAS groundwater concentrations observed in the 2020 sampling event were consistent with prior periods. As well, certain control measures have been put in place at the Site to reduce PFAS emissions and limit contact of process and non-process water with groundwater, which reduce contributions of PFAS to groundwater. The remainder of this report is organized as follows: • Background – presents relevant background information regarding Site conditions; • Scope and Methods – describes the sampling programs performed in 2020 and methods used in the sampling activities; DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 2 February 2021 • Sampling Results and Discussion – presents and discusses the results of the sampling activities; and • Summary – summarizes the purpose and findings of this report. 2 BACKGROUND 2.1 Site Background The Site is located within a 2,177-acre property at 22828 NC Highway 87, approximately 20 miles southeast of the city of Fayetteville along the Bladen-Cumberland county line in North Carolina. Figure 1 presents the location of the Site. The Site property was originally purchased by E.I. du Pont de Nemours and Company (DuPont) in 1970 for production of nylon strapping and elastomeric tape. DuPont sold its Butacite® and SentryGlas® manufacturing units to Kuraray America Inc. (Kuraray) in June 2014 and subsequently separated its specialty chemicals business, with Chemours becoming an independent operator in July 2015. The manufacturing area is approximately 312 acres, and the remaining areas are grassy areas, forests and wetlands. Presently, the Site consists of five manufacturing areas (Figure 1): Chemours Monomers IXM (Area 1); Chemours Polymer Processing Aid (PPA; Area 2); Kuraray Butacite® (Area 3); Kuraray SentryGlas® (Area 4); and DuPont Company polyvinyl fluoride (PVF) resin manufacturing unit (Area 5). In addition to the manufacturing operations, Chemours operates two natural gas-fired boilers, a wastewater treatment plant (WWTP) for the treatment of sanitary wastewaters as well as process wastewaters from Kuraray and DuPont, and a thermal oxidizer for treatment of air emissions. 2.2 Regional Geology Previously the Site geology was presented as four geological units; the Cretaceous Cape Fear formation (the oldest formation), the Cretaceous Black Creek formation, the surficial aquifer, and sediments along the Cape Fear River, designated as floodplain deposits. The recent (2109 and 2020) investigation activities completed as part of the Comprehensive Site Assessment (CSA) along with additional research has identified resources that better describe the geology of the area and the nature of the depositional environments at the Site. The Surficial Geologic Map of the Elizabethtown 30’ x 60’ Quadrangle, North Carolina (Weems, Lewis, & and Crider, 2011) presents an updated description of the geological units present at the Site. The Cape Fear formation is interpreted to be either a marginal marine or deltaic environment, consisting of interbedded clays and sands. Clay beds of the Cape Fear DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 3 February 2021 formation are typically pale to medium gray. According to literature, the clay strata can be up to 8 feet in thickness. Formation sands are either massive or poorly cross-bedded and commonly contain clay clasts. Sands range from fine to very coarse grained (Sohl & Owens, 1991). The Tar Heel formation of the Black Creek Group overlies the Cape Fear formation unconformably. In the area of the Site, the Tar Heel formation is interpreted to be a delta plain depositional area. The Tar Heel formation is comprised of horizontal beds of black carbonaceous clays that are interbedded with sands. Wood is especially common in these facies, with silicified logs present. The deltaic sequences generally have a mixture of higher energy channel sands and lower energy mud flats typical of transgressive and regressive sequences of sea water levels. The Black Creek Aquifer designation will continue to be used when referencing the aquifer unit at Site of the Tar Heel formation to maintain consistency with prior reporting. The Varina Grove unit of early Pleistocene age unconformably overlies the Black Creek group and in previous Site-related reports was designated as the surficial aquifer. The Varina Grove unit consists of sands, very fine to fine grained, silty and clayey, grading downward through fine to medium to medium to coarse to very coarse-grained sands. The sands and clay are generally dark grayish orange and/or dark yellow brown and are considered to be terrace deposits. The Varina Grove unit will continue to be designated as the surficial aquifer as this is the first unconfined aquifer encountered at the Site and this terminology maintains the convention for designating the uppermost aquifer as the surficial aquifer for hydrogeological purposes. The Floodplain Deposits that are identified on the Elizabethtown geologic map are older alluvium of the late Pleistocene age. Deposits are described as gravel, with rounded to sub-rounded quartz clasts up to f the 6 cm in diameter in a silty quartzose. Color is typically dark grayish orange. 2.3 Site Geology and Hydrogeology The Site is located in the Coastal Plain of North Carolina and is situated adjacent to the Cape Fear River atop a bluff with a 100-foot elevation change to a floodplain area and the Cape Fear River. To the north, Willis Creek borders the Site, which flows through an erosional channel and empties into the Cape Fear River. To the south of the southern property boundary of the Site is Georgia Branch Creek which also flows through erosional channels and empties into the Cape Fear River. Onsite there are streams and seeps that are fed in some capacity by groundwater and these flow to the Cape Fear River. DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 4 February 2021 The largest of these is the Old Outfall 002 channel, along with four onsite seeps (A, B, C and D), identified on the bluff slope facing the Cape Fear River (Figure 1). Three groundwater bearing units at Site have been identified, the Perched Zone, the Surficial Aquifer and the Black Creek Aquifer along with Floodplain Deposits adjacent to the Cape Fear River. The Perched Zone and Surficial Aquifer are parts of the Varina Grove formation while the Black Creek Aquifer is part of the Tar Heel formation aquifer. The Perched Zone is separated from the Surficial Aquifer by the Perched Clay Unit, the Surficial Aquifer is separated from the Black Creek Aquifer by the Black Creek Confining Unit and in turn the Black Creek Aquifer is separated from the underlying Upper Cape Fear Aquifer by the Upper Cape Fear Confining Unit. Details for each of these units and a description of an erosional feature cutting through the Black Creek Confining Unit are presented below. Perched Zone: The Perched Zone is a relatively thin, spatially limited layer of groundwater present in silty sands to a depth of about 20 feet (ft) below ground surface (ft bgs). Groundwater in the Perched Zone is recharged through precipitation onsite, and in the past water in the unlined ditches and sedimentation ponds would have also contributed to recharge. The sedimentation ponds and the cooling water channel in the Monomers IXM Area have been lined to reduce infiltration. Groundwater flows radially away from groundwater mounds in the Perched Zone. This leads to groundwater discharge to the east at seeps on the edge of the bluff, to the south toward the Old Outfall 002 and to the north and to the west downwards through the geological sequence towards the Surficial and Black Creek Aquifers. Perched Clay Unit: The Perched Clay Unit gives rise to the Perched Zone as it presents a barrier to direct downward groundwater infiltration. The Perched Clay is spatially limited at the Site. To the north it pinches out. To the east and south, it outcrops along the bluff face. To the west it terminates and becomes absent. In cross sections through the Site and observations of grain sizes and lithologic contact elevations from boring logs, it suggests that there may be an erosional feature in the western portion of the Site underlying the manufacturing areas. This erosional surface, described below, is interpreted to have eroded the Perched Clay Unit which would then enable downward migration of groundwater off the western edge of the Perched Zone. Surficial Aquifer: The Surficial Aquifer is an unconfined silty sand aquifer above the Black Creek Confining Unit and is present beneath the Perched Clay Unit. Groundwater in the Surficial Aquifer flows towards the bluff faces at the Site. It flows both north, east and west toward surface water bodies (Willis Creek, Seeps, Old Outfall 002) and discharges into them. The Surficial Aquifer is interpreted to be in contact with the Black Creek Aquifer in places due to an erosional feature. This feature is labeled on the cross DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 5 February 2021 sections and is interpreted to have enabled downward cross formational groundwater flow. Black Creek Confining Unit: The Black Creek Confining Unit is a layer of silty or sandy clay that separates the Surficial Aquifer from the Black Creek Aquifer. The lithologic contact elevation with the overlying Surficial Aquifer is variable, as is the unit thickness –the Black Creek Confining Unit is interpreted to have been eroded under the western portion of the manufacturing areas at Site. In addition to the Black Creek Confining unit being discontinuous, the potential for downward cross formational flow, also exists based on multiple vertical joints (i.e., fractures in the clay) observed in the Black Creek Confining Unit where it outcrops at the Site. Flood Plain Deposits: Surface soils in the flood plain immediately adjacent to the Cape Fear River are comprised of finer grained, late Pleistocene alluvium deposits. These deposits have lower hydraulic conductivity than the Surficial and Black Creek Aquifers. The seeps at the Site cut into Floodplain Deposits as they flow towards the Cape Fear River. Black Creek Aquifer: The Black Creek Aquifer is comprised of fine to medium grained sands. The Black Creek Aquifer is in contact with the Surficial Aquifer under the western portion of the manufacturing area at the Site and then is separated from the Surficial Aquifer under most of the manufacturing area by the Black Creek confining unit. The Black Creek Aquifer directly adjacent to the Cape Fear River is overlain by Flood Plain Deposits and the Black Creek Confining Unit. The Black Creek Aquifer is interpreted to be the only transmissive groundwater zone at Site in direct contact with the Cape Fear River. Groundwater in the Black Creek Aquifer flows from west to east towards the Cape Fear River. Upper Cape Fear Confining Unit: The Upper Cape Fear Confining Unit underlies the Black Creek Aquifer. The Upper Cape Fear Confining unit is a regionally extensive clay layer which is upwards of 75 ft thick at the Site and is likely a barrier to downwards groundwater flow. Groundwater levels in the Upper Cape Fear Aquifer measured at North Carolina Division of Water Resources (NC DWR) wells are 80 ft lower than Black Creek Aquifer groundwater levels immediately above the Upper Cape Fear Aquifer. If the two units were in hydraulic connection, they would have similar groundwater elevations. The dissimilarity in water levels for these co-located NC DWR wells demonstrates that the Upper Cape Fear Confining Unit is a barrier to downward flow from the Black Creek Aquifer to the Cape Fear Aquifer. Erosional Feature: A paleo-era process appears to have eroded the Perched Clay Unit, portions of the Surficial Aquifer and the Black Creek Confining Unit in the geological sequence under the western portion of the manufacturing area. This erosional feature DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 6 February 2021 potentially enables cross formational flow of groundwater from the Perched Zone, through the Surficial Aquifer and into the Black Creek Aquifer. This feature is a likely controlling factor of the distribution of PFAS observed in the Surficial and Black Creek Aquifers at Site. 3 SCOPE AND METHODS The 2020 Onsite and Offsite Groundwater Sampling event was completed by Geosyntec and Parsons of NC (Parsons) in July and August 2020. Two additional locations (NAF- 05A and NAF-13) were sampled in October. These monitoring wells are located in a restricted access zone and can only be sampled when manufacturing is not happening (i.e., in October during the facility turnaround time). The scope of the sampling program and methods employed to collect field data are summarized below. Complete descriptions of the field methods can be found in the Appendix A. 3.1 Sampling Activities in July and August 2020 On and offsite groundwater sampling activities included: 1. Collecting a synoptic round of water levels from onsite and offsite monitoring wells in July 2020 (Table 3A and Table 3B); 2. Measurement of field parameters as described in Appendix A (Table 4A and Table 4B); and 3. Collection and analysis of groundwater samples and QA/QC samples for Table3+ and Method EPA 537 Modified PFAS from 114 onsite wells and 17 offsite monitoring wells in July, August, and October1 2020 (Table 5A, Table 5B, and Table 5C). Groundwater samples were collected using low-flow sampling techniques as described in the Appendix A. Depth to groundwater measurements were conducted on July 8, 2020. The methods used for groundwater sample collection are outlined in Appendix A. 3.2 Laboratory Analyses Groundwater samples were analyzed for PFAS by Table 3+ Laboratory SOP and for Method EPA 537 Modified. PFAS reported under these methods are listed in Table 1 and in Appendix C. The focus of this report is on Table 3+ PFAS; therefore, results of sampling activities were performed and presented with respect to Table 3+ PFAS. Analytical results of PFAS analyzed under Method EPA 537 Modified, with the 1 Two onsite wells (NAF-05A and NAF-13) were sampled in October 2020 during facility turn around (TAR) due to their proximity to the blast zone.

Specifically, this section describes data quality regarding data reported in this report and then describes the results from the onsite and offsite groundwater well sampling. 4.1 Data Quality All 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 manual review 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. 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 (RPDs) 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 and includes instrument-related quality control results for calibration standards, blanks, and recoveries. The data review process (DVM plus manual review) applied the following data evaluation qualifiers to the analytical results as required: DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 8 February 2021 • 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. The data review process described above was performed for all laboratory chemical analytical data generated for the sampling event. 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 R-PSDA, Hydrolyzed PSDA, and R-EVE. 4.1.1 Table 3+ 17 Compounds For clarity, the text and figures of this report describe the Total Table 3+ (17 compounds) while Total Table 3+ (20 compounds) are included in the tables. As reported in the Matrix Interference During Analysis of Table 3+ Compounds memorandum (Geosyntec, 2020a), matrix interference studies conducted by the analytical laboratory (TestAmerica, Sacramento) have shown that the quantitation of three compounds (R-PSDA [formerly Byproduct 4], Hydrolyzed PSDA [formerly Byproduct 5], and R-EVE) is inaccurate due to interferences by the sample matrix in both groundwater and surface water. 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+ (17 compounds)”, i.e., excluding results of R-PSDA, Hydrolyzed PSDA, and R-EVE, and (ii) summing over 20 of the Table 3+ compounds “Total Table 3+ (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 all 17 compounds is an underestimate of the actual value while the sum of the 20 compounds is likely an overestimate of the actual value. 4.2 Groundwater QA/QC Samples PFAS concentrations for groundwater QA/QC samples are reported in Table 5C. The following observations were noted for the QA/QC samples: • Forty-one (41) equipment blanks were collected over 24 sampling days. No PFAS were detected above the associated reporting limits in 31 of the 41 equipment blanks. The ten equipment blanks with reported PFAS concentrations were collected on July 9, 13, 17, 23, 24 27 and October 15, 2020. These equipment blanks with reportable concentrations had detections of HFPO-DA (6 samples), Hydrolyzed PSDA (4 samples), PFMOAA (1 sample), PFO2HxA (2 samples), DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 9 February 2021 and PFO3OA (1 sample). Samples collected on July 9, 13, 17, 23, 24 27 and October 15, 2020 that had concentrations of HFPO-DA, Hydrolyzed PSDA, PFMOAA, PFO2HxA, or PFO3OA within 5x the concentration reported in the equipment blank sample were B qualified to indicate the presence of the analyte in the associated equipment blank sample. Concentrations of compounds in the equipment blanks ranged from 2.3 to 49 ng/L. • Twenty-four (24) field blanks were collected over the 24 sampling days. No PFAS were detected above the associated reporting limits in 20 of the 24 field blanks. The field blanks with reported concentrations were collected on July 17 and 27, 2020. The July 17 field blank had a Hydrolyzed PSDA concentration of 2.2 ng/L and the July 27 field blank sample had a HFPO-DA concentration of 2 ng/L. Results for Hydrolyzed PSDA and HFPO-DA from July 17 and 27, 2020 within 5 times the concentration found in the field blank were B qualified to indicate the presence of the analyte in the associated field blank sample, respectively. • Seven field duplicate samples were collected for onsite wells (Table 5A) and one duplicate sample was collected for offsite wells (Table 5B). Relative percent differences for the reported compounds were less than 30% with the exception of PEPA, PES and PFECA-B in the parent and field duplicate samples from LTW- 03. These results were J-qualified as estimated. 4.3 Onsite Groundwater Sampling Results This section presents the results of the onsite groundwater elevation survey, groundwater field parameter measurements and groundwater PFAS analytical results. 4.3.1 Onsite Groundwater Elevations Groundwater elevations were calculated from synoptic water levels measured at 123 wells on July 8, 2020 at the onsite wells screened in the Perched Zone, Surficial Aquifer and Black Creek Aquifer (Table 3A; Figures 4A through 4C). Similar to previous assessments (Geosyntec, 2019b; Geosyntec, 2020b; Geosyntec, 2020c), groundwater elevations were highest in the central portion of the Perched Zone near the Power and Monomers IXM area of the Site. Perched Zone groundwater elevations appear to be controlled by topography and the lateral extent of the clay lens. Groundwater elevations in Surficial Aquifer wells (Figure 4B) indicate groundwater flow in the northern portion of the Site is likely to be east-northeast towards both Willis Creek and Cape Fear River, and at the southern end of the Site towards Old Outfall 002, DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 10 February 2021 consistent with the flow observed in previous assessments (Parsons, 2018; Geosyntec 2019a; Geosyntec, 2020b; Geosyntec, 2020c). Groundwater in the Black Creek Aquifer flows in a predominantly easterly direction to the Cape Fear River (Figure 4C) similar to groundwater elevations discussed in previous assessments (Parsons, 2018; Geosyntec, 2019b; Geosyntec, 2020b; Geosyntec, 2020c). A portion of Black Creek Aquifer groundwater flow is interpreted to also flow to the northeast, towards Willis Creek (near SMW-12) and southeast, towards Old Outfall (east of PW-11 or Glengerry Road). 4.3.2 Onsite Groundwater Table 3+ PFAS Analytical Results Table 3+ PFAS and Total Table 3+ field parameters recorded at 114 onsite groundwater wells during the annual sampling event are presented in Table 4A and the field forms are provided in Appendix B. Field parameter data are generally in line with expectations for these groundwater samples, with the exception of turbidity at PW-03, which was 3666 NTU. This sample was field filtered before laboratory analysis due to the high turbidity. This location also had the highest turbidity in the 2019 annual sampling event. Table 3+ PFAS and Total Table 3+ concentrations for the onsite groundwater samples collected during the annual sampling event are presented in Table 5A and Figures 6A, 6B, and 6C. Laboratory and DVM reports are included in Appendix D. The Table 3+ PFAS compounds with the highest frequency of detections and highest concentrations were HFPO-DA, PFOH2xA, PFMOAA, and PMPA. In samples that had detections, these four compounds accounted for 40% to 100% of Total Table 3+ concentrations (Table 5A). PFECA-B and PFECA-G were not in the samples collected from onsite wells. Total Table 3+ PFAS concentrations ranged from non-detect at PW-09 and PW-12 to 2,700,000 ng/L at NAF-02 (Table 5A). In general, the highest Total Table 3+ concentrations were observed in areas of historical releases in the manufacturing area (e.g., Monomers IXM) and decrease with distance in the direction of groundwater flow (Figures 6A, 6B and 6C). By water bearing unit, the highest Total Table 3+ concentrations were observed in the Perched Zone and were generally clustered around the northeastern part of the Monomers IXM area (Table 5A; Figure 6A). Total Table 3+ concentrations observed in the Surficial Aquifer were lower than the Perched zone and ranged from 1,200 ng/L at MW-18D and 1,500,000 ng/L at SMW-06B, respectively (Table 5A; Figure 6B). Total Table 3+ concentrations observed in the Black Creek Aquifer were lower than the Surficial Aquifer and ranged from non-detect at PW-09 and PW-12 and 780,000 ng/L at SMW-03B, respectively (Table 5A; Figure 6C). Within the Black Creek Aquifer, lower DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 11 February 2021 concentrations are observed on the western portion of the Site (upgradient) and in the northern portion of the Site near Willis Creek. Table 3+ PFAS concentrations upgradient of the facility are non-detect with the highest concentrations located under the facility and resulting in concentrations being present downgradient. Sample results for other PFAS compounds analyzed by EPA Modified Method 537 are reported in Appendix C. In general, concentrations of Modified Method 537 compounds are less frequently detected and orders of magnitude lower than the Table 3+ compounds. Overall, results from the 2020 Onsite Groundwater sampling event are consistent with trends observed at these wells in previous monitoring events (Geosyntec 2019a; Geosyntec; 2019b). 4.4 Offsite Groundwater Sampling Results This section presents the results of the offsite groundwater elevation survey, groundwater field parameter measurements and groundwater PFAS analytical results. There are twenty (20) offsite groundwater monitoring wells: ten (10) are screened in the Surficial Aquifer (well names ending in “S”) and ten (10) are screened in the Black Creek Aquifer (well names ending in “D”). Water levels were recorded at eighteen (18) of these offsite wells and samples were collected at seventeen (17) of these offsite wells. Bladen-1D and Cumberland-5D were damaged and neither a water level nor a sample was collected. A water level was measured at Bladen-1S during the synoptic water level event on July 8, 2020, but a sample was not collected because the well was purged dry. 4.4.1 Offsite Groundwater Elevations Groundwater elevations were calculated from synoptic water levels measured at 18 offsite wells from a single synoptic water level measurement survey performed on July 8, 2020 (Table 3B; Figure 5). The ground elevations of offsite wells vary from 60.06 to 175.2 feet and there are spatial ranges of up to 12 miles between offsite well locations. Groundwater elevations at wells screened in the Surficial Aquifer ranged from 54.96 feet to 171.98 feet, while groundwater elevations at wells screened in the Black Creek Aquifer ranged from 59.22 feet to 171.79 feet. Given the distance between offsite wells, we do not feel it is appropriate to infer groundwater flow properties. 4.4.2 Offsite Groundwater PFAS Analytical Results Samples were collected at 17 of the offsite groundwater wells: 9 screened in the Surficial Aquifer and 8 screened in the Black Creek Aquifer. Field parameters recorded at 17 offsite wells are presented in Table 4B and the field forms are provided in Appendix B. Recorded field parameter data are generally in line with expectations for the sample DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 12 February 2021 locations and sampling techniques. The locations that were dry and not sampled were Bladen-1S, Bladen-1D, and Cumberland-5D Total and individual Table 3+ PFAS concentrations for the offsite wells are reported in Table 5B and Figure 7. Laboratory and DVM reports are included in Appendix D. In general, detection frequencies and concentrations were low in the offsite wells for most Table 3+ compounds (Table 5B). There were no detections in samples collected from the offsite wells screened in the Black Creek Aquifer. All nine of the samples collected from offsite wells screened in the Surficial Aquifer had detections of Table 3+ compounds. Among these nine wells with detections, only nine out of the 20 Table 3+ compounds were detected and the following five Table 3+ compounds had concentrations that exceeded 10 ng/L • HFPO-DA (four samples detected) at concentrations that ranged from 3.8 ng/L to 45 ng/L; • PFMOAA (eight samples detected) at concentrations that ranged from 3.1 ng/L to 19 ng/L; • PFO2HxA (seven samples detected) at concentrations that ranged from 4 ng/L to 51 ng/L; • PMPA (five samples detected) at concentrations that ranged from 21 ng/L to 84 ng/L; and • PEPA (one sample detected) at a concentration of 14 ng/L; At the nine offsite wells with detections, Total Table 3+ PFAS concentrations ranged from 5.3 ng/L at Cumberland-5S to 230 ng/L at Cumberland 4S (Figure 7). In general, the largest proportion of Total Table 3+ concentrations detected in the offsite wells were those compounds listed above, which accounted for 88% to 100% of the Total Table 3+ concentrations. These trends are consistent with the 2019 on and offsite groundwater sampling event (Geosyntec, 2019a; Geosyntec, 2019b). Samples results for other PFAS compounds analyzed by EPA Modified Method 537 are reported in Appendix C. In general, concentrations of Modified Method 537 compounds are less frequently detected (8 of 35 compounds at 7 offsite wells) and are mostly below 10 ng/L. 5 SUMMARY This report outlines the annual groundwater sampling event conducted in July and August of 2020. The scope of work included a synoptic round of groundwater elevations and collection of groundwater samples. Samples were collected from 112 onsite wells and 17 DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 13 February 2021 offsite monitoring wells and analyzed for PFAS by Table 3+ Laboratory SOP and for Method EPA 537 Modified. Overall, results from the 2020 Annual Onsite and Offsite Groundwater sampling event are consistent with trends observed at these wells in previous monitoring events (Geosyntec, 2019a). More specifically, the groundwater flow patterns for each water bearing unit are consistent with those observed in previous assessments (Geosyntec 2019a; Geosyntec 2020b; Geosyntec 2020c): • Perched Zone - groundwater elevations were highest in the central portion of the perched zone near the Power and Monomers IXM area of the Site (Figure 4A); • Surficial Aquifer – groundwater elevations indicate that in the northern portion of the Site, groundwater flows easterly and northeasterly towards both Willis Creek and Cape Fear River, and in the southern portion of the Site groundwater flows to the east toward the Cape Fear River and Old Outfall 002 (Figure 4B); and • Black Creek Aquifer – groundwater elevations indicate that groundwater flows in a predominantly easterly direction to the Cape Fear River (Figure 4C). The results of the groundwater sampling at the onsite wells indicate that Total Table 3+ PFAS concentrations ranged from non-detect at PW-09 and PW-12 (screened in the Black Creek Aquifer) to 2,700,000 ng/L at NAF-02 (screened in the Perched Zone). In general, the highest Table 3+ PFAS concentrations were present in areas of known historical releases and decrease with distance in the direction of groundwater flow. For onsite monitoring locations, there were no significant changes in groundwater flow velocities and PFAS concentrations observed in the 2020 sampling event were consistent with prior sampling events. As well, certain control measures have been put in place at the Site to reduce PFAS emissions and limit contact of process and non-process water with groundwater, which reduce contributions of PFAS to groundwater. The results of the groundwater sampling at the offsite wells is presented in Table 5B. There were no detections of Total Table 3+ PFAS in the offsite wells screened in the Black Creek Aquifer. For offsite wells screened in the Surficial Aquifer, Total Table 3+ PFAS concentrations ranged from non-detect at nine (9) wells to 230 ng/L at Cumberland-4S. There were only five (5) Table 3+ compounds that were detected in offsite wells screened in the Surficial Aquifer at concentrations exceeding 10 ng/L. Pursuant to the CAP, sitewide annual groundwater sampling and offsite monitoring well sampling will next be performed in the third quarter 2021 in coordination with multiple other monitoring activities occurring in 2021, such as the Cape Fear River PFAS Mass DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 2020 Annual GW Report.docx 14 February 2021 Loading Assessment Sampling which occurs and is reported at minimum on a quarterly basis.

The effort described herein was conducted by Geosyntec and Parsons in July and August 2020. The scope of the sampling program and methods employed to collect field data are summarized below. SCOPE OF WORK The scope of work involves two sampling activities: (1) Collecting a synoptic round of groundwater elevations from on and offsite monitoring wells (July 2020); (2) Collecting water samples for PFAS from 112 onsite wells and 17 offsite monitoring wells (July and August 2020). Field methods for each task are described below in the Methods section. Field forms collected during implementation of this scope of work are provided in Appendix B. The work was performed according to the project health and safety plan (HASP) prepared by Parsons (Parsons Health and Safety Plan Chemours Fayetteville Site, 2020). A Plan on Action Discussion (POAD) and Project Safety Analysis (PSA) was held prior to commencing field activities. The work was performed under Nationwide Permit 6 (United States Army Corps of Engineers, 2017). METHODS This section describes the field methods and procedures that were employed for collection of groundwater elevations water quality parameter assessment and sample collection. Synoptic Water Level Measurements Water level measurements for monitoring wells listed in Tables 3A and 3B were collected during a single synoptic event. At each location, notes on well condition, weather, date and time of collection, depth to bottom of well and depth to water level from top of casing were recorded. Groundwater Sampling Methods Designated monitoring wells were monitored as part of the yearly monitoring activities. These wells are listed in Table 2 and Figures 2 and 3. The groundwater samples were analyzed for the list of PFAS compounds listed in Table 1. Field equipment was inspected by the program on-Site supervisor and calibrated daily prior to use according to the manufacturer’s recommended guidelines. Field parameters were measured with a water quality meter after sample collection and included the following: •pH; DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E Appendix A 2 February 2021 •Temperature (°C); •Specific Conductivity (µS/cm); •DO (mg/L); •ORP (mV); •Turbidity (nephelometric turbidity units [NTU]); and, •Color. Non-dedicated or non-disposable sampling equipment was decontaminated immediately before sample collection in the following manner: 1.De-ionized water rinse; 2. Scrub with de-ionized water containing non-phosphate detergent (i.e., Alconox®); and 3.De-ionized water rinse. Disposable equipment (e.g. gloves, tubing, etc.) was not reused. New sample containers were used for each sample. Groundwater samples were collected, where possible, using low-flow sampling techniques as discussed in detail in the Long-term Groundwater Monitoring Plan (Parsons, 2018) and briefly summarized here. 1. New disposable or dedicated HDPE tubing was placed at the midpoint of the well’s screened interval. 2.Water was purged through a flow-through cell attached to a water quality meter capable of measuring pH, temperature, specific conductivity, dissolved oxygen, and ORP. 3.Water was pumped using a peristaltic pump, with dedicated silicone tubing for the pump head, at wells with water level less than 30 feet. A submersible pump was used for wells with water level deeper than 30 feet. 4. Groundwater was pumped directly from submerged tubing through the pump head to a flow-through cell until field parameters (pH, temperature, specific conductivity, DO, ORP) were stabilized within ±10% over three consecutive readings within a five-minute interval. If field parameters stabilized, but turbidity remained stable yet elevated greater than 20 NTU, field personnel purged five well volumes prior to sample collection. 5. Water levels in the designated wells were monitored during purging so that minimum draw- down of the water column was maintained. 6.Once flow-through cell readings were stable, the flow-through cell was disconnected, the tubing cut to provide a new clean end and samples were collected from the discharge of the peristaltic pump in new 250 mL laboratory-supplied HDPE bottles. 7.Sample identification information (e.g., well/sample identification number, sample time and date, samplers’ names, preservative, and analytical parameters) were recorded on the bottle label with permanent ink after the sample was collected. DocuSign Envelope ID: 30A80025-9A94-448A-A323-3108F58ADF9E 3 February 2021 Appendix A Sample Packing and Shipping Upon sample collection, each containerized sample was placed into an insulated sample cooler. Wet ice was placed around the sample containers within heavy-duty plastic bags within the sample cooler. A chain-of-custody form was completed by the field sample custodian for each sample shipment. Sample locations, sample identification numbers, description of samples, number of samples collected, and specific laboratory analyses were recorded on the chain-of-custody form. Field QA/QC Samples Field quality assurance/ quality control (QA/QC) samples were collected as discussed in detail in the Long-term Groundwater Monitoring Plan (Parsons, 2018) and summarized below: 1.Thirty-nine (39) equipment blanks were collected over 22 sampling days (Tables 5C and C3). 2.Twenty-two field blanks were collected over the 22 sampling days (Tables 5C and C3) 3.Six field duplicate samples were collected for onsite wells (Tables 5A and C1) and one duplicate sample was collected for offsite wells (Tables 5A and C2).

Overall the data is acceptable for use without qualification, except as noted below: •Some results were qualified B and the reported results may be biased high, or false positives, due to a comparable concentration found in the associated equipment or field blank. •Professional judgement was used to overwrite R qualifiers, indicating an unusable result, that were assigned by the DVM to non-detect results due to the preparation or analytical hold timethat was exceeded by more than two times. The qualifier was updated to UJ, indicating anestimated reporting limit, because the target compounds are generally recognized to be stable for an extended time period. •Due to uncertainty from observed matrix effects during the analysis of R-PSDA, HydrolyzedPSDA and R-EVE, a J-qualifier has been added to all positive results in the data set, if not alreadyqualified 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. •Several analytical results have been qualified J as estimated, and non-detect results qualified UJindicating an estimated reporting limit, due to poor recovery of a surrogate, lab control spike, ormatrix spike; a transition mass ratio for the indicated analyte outside of the established ratiolimits, and; poor field duplicate precision. See the Data Verification Module (DVM) NarrativeReport for which samples were qualified, the specific reasons for qualification, and potential bias in reported results Attachments The DVM Narrative report is attached. 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.

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 RPDbetween 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.
