The effort described herein was conducted by Geosyntec and Parsons in December 2020. The monitoring program includes collecting data on flow rates and PFAS concentrations from the PFAS transport pathways to the Cape Fear River. SCOPE OF WORK The scope of work involves four tasks: (1) collecting surface water and groundwater seep water samples for PFAS; (2) measuring flow rates at specified surface water and seep locations; (3) collecting a synoptic round of groundwater elevations from designated monitoring wells; and (4) collecting water samples for PFAS analysis from the designated monitoring wells. 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 E. 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 collecting surface water and onsite seep samples, gauging stream flow, collection of groundwater elevations, water quality parameter assessment and sample collection. Surface Water and Onsite Seep Sample Collection Methods Surface Water and Onsite Seep Composite Sampling Methods Autosamplers were used to collect 24-hour integrated samples from various surface water bodies and onsite Seeps. The autosamplers collected sample aliquots once per hour. The sample tubing from the autosampler was positioned at minimum 2 inches above the bottom of the water body flow with the open end of the sample tubing pointed in the downstream direction to minimize the potential for sediment accumulation and uptake. Autosampler materials consisted of high-density polyethylene (HDPE) tubing, silicon tubing, and an HDPE sample reservoir. Water from the Appendix A 2 March 2021 sample reservoir was decanted into laboratory supplied bottles (e.g. 250-milliliter [mL] HDPE bottles for PFAS analysis) and then sent to an approved laboratory. Field parameters were measured twice for composite samples: once during composite sampling (collected directly from the water stream), and once after composite sampling (collected from the autosampler reservoir). The following water quality parameters were recorded: pH; Temperature (degrees Celsius [°C]); Specific Conductivity (microsiemens per centimeter [µS/cm]); Dissolved Oxygen (DO) (milligrams per liter [mg/L]); and, Oxidation-Reduction Potential (ORP) (millivolts [mV]) Creek and Seep Water Grab Sampling Methods Where composite sample collection was not feasible due to access and other field conditions, creek and seep water samples were collected as grab samples. Laboratory-supplied 250 mL HDPE sample bottles were lowered into the flowing water of the creek to collect the sample. The bottles were lowered into the stream either using a properly decontaminated dip rod with bottle attached with a nylon zip tie, or in shallow streams, by hand. The bottle was lowered into the stream with the cap removed, open and facing oncoming flow. Where possible, the sample was collected from the middle of the stream. Care was taken to avoid collecting suspended solids or other materials in the sample. The following water quality parameters were measured after sample collection using water from the same location in the stream: pH; Temperature (°C); Specific Conductivity (µS/cm); DO (mg/L); and ORP (mV). Cape Fear River Water Grab Sampling Methods Cape Fear River water samples were collected using a peristaltic pump and new dedicated HDPE tubing and dedicated silicone tubing for the pump head at each location. The tubing was lowered to the specified sampling depth below the water surface using an anchor weight and the tubing fastened to the anchor pointing upwards. Surface water was pumped directly from the submerged tubing through the pump head to a flow-through cell. Field parameters were monitored over a 5- minute interval, then the flow-through cell was disconnected, the tubing cut to provide a new, clean end and a grab sample was collected from the discharge of the peristaltic pump in new 250 mL laboratory-supplied HDPE bottles. The following water quality parameters were measured: pH; Temperature (°C); Appendix A 3 March 2021 Specific Conductivity (µS/cm); DO (mg/L); and ORP (mV). Flow Gauging Methods Flow velocity was measured after sample collection at seep and creek locations specified in Table 2. Flow velocity was measured using flumes where they exist, otherwise flow velocity was measured via flow meters. Flumes Flumes are currently installed in Seep A, Seep B, Seep C, Seep D, and Old Outfall 002 under Nationwide Permit 38 (United States Army Corps of Engineers, June 2019). Where present, they were used to calculate flow based on the data collected by the level logger installed in the flume. Flow Velocity Gauging Where flumes are not installed (i.e., Willis Creek and Georgia Branch Creek), the flow rate of the stream was measured using a submersible flow meter. The flow meter was placed beneath the flowing stream along the cross section of the stream at regular intervals (e.g. every six inches) and the height of the water was recorded along with the recorded water velocity. These measurements were then used to calculate the volumetric flow of water passing through the structure based on the regular geometry and measured flow rates. Flow was measured using two to three transects to assess variability in estimated flow. Transects were selected that have fairly uniform cross sections that could be gauged with minimal disturbance. Synoptic Water Level Measurements Water level measurements for monitoring wells listed in Table 3 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 quarterly monitoring activities. These wells are listed in Table 3 and Figure 7a-c. 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; Temperature (°C); Appendix A 4 March 2021 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. 5 March 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.For samples collected to be analyzed by Method Table 3+, two blind duplicate samples were collected; 2.For samples collected to be analyzed by Method Table 3+, three MS/MSD samples were collected; 3.For groundwater samples collected in December, equipment blanks and field blanks were collected daily. 4.For surface water samples collected in December, four equipment blanks and two field blanks were collected.

TR0795A March 2021 APPENDIX B Cape Fear River Mass Loading Calculations Appendix B 1 March 2021 APPENDIX B CAPE FEAR RIVER MASS LOADING CALCULATIONS This appendix presents the methodology for calculating three types of mass loads: 1.The total measured in-river PFAS mass load based on time-weighted concentration measurements of PFAS primarily from composite samples of Cape Fear River water and measured Cape Fear River flow volumes at the W.O. Huske Dam that are adjusted for travel times to the downstream monitoring location at the CFR-TARHEEL; 2.The total measured and estimated PFAS mass load captured by remedies implemented by Chemours; this is the load fraction that was prevented from reaching the Cape Fear River; and 3.The total measured Total PFAS mass load to the Cape Fear River defined as the sum of the measured in-river loads and the remedy prevented loads. The following sections detailed calculation methods for each type of mass load: Total, River and Captured Mass Loads. Total Mass Load Calculation Methodology The Total Mass Load is calculated following Equation 1 below: Equation 1: Total PFAS Mass Load 𝑀𝑀𝐶𝐶𝐶𝐶𝐶𝐶= 𝑚𝑚𝐶𝐶𝐶𝐶𝐶𝐶+𝑚𝑚𝐶𝐶𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 where, 𝑀𝑀𝐶𝐶𝐶𝐶𝐶𝐶 = is the Mass Load of PFAS compounds in the Cape Fear River, including the mass load prevented from reaching the Cape Fear River by implemented remedies, measured in kilograms (kg); 𝑚𝑚𝐶𝐶𝐶𝐶𝐶𝐶 = is the River Mass Load estimated using PFAS concentrations in samples taken in the Cape Fear River downstream of the Site where the river is well mixed and using measured river flow volumes; and 𝑚𝑚𝐶𝐶𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 = is the Captured Mass Load prevented from reaching the Cape Fear River by remedies implemented by Chemours; The following subsections describe how the River and Captured Mass Loads are calculated. River Mass Load Calculation Methodology The River Mass Load is the estimated mass, in kilograms, that has reached the Cape Fear River over a period of time. The River Mass Load, 𝑚𝑚𝐶𝐶𝐶𝐶𝐶𝐶, is calculated using primarily composite samples from the Cape Fear River and corresponding river flow volumes. The River Mass Load is calculated for a given time period following Equation 2 below: Appendix B 2 March 2021 Equation 2: Cape Fear River Estimated Mass Discharge from Mass Loading Model 𝑀𝑀𝑀𝑀𝐶𝐶𝐶𝐶𝐶𝐶= ��𝑀𝑀𝑀𝑀𝑝𝑝,𝑅𝑅=���𝐶𝐶𝑛𝑛,𝑅𝑅× 𝑄𝑄𝑛𝑛� 𝐼𝐼 𝑅𝑅=1 9 𝑝𝑝=1 𝐼𝐼 𝑅𝑅=1 9 𝑝𝑝=1 where, MDCFR = Total PFAS estimated mass discharge entering the Cape Fear River, measured in mass per unit time [MT-1], typically mg/s; p = represents each of the 9 potential PFAS transport pathways described further in Section 4.4. To facilitate model construction, the Seeps (Transport Pathway 6) were further discretized as Seep A (Transport Pathway 6A), Seep B (Transport Pathway 6B), Seep C (Transport Pathway 6C) and Seep D (Transport Pathway 6D); i = represents each of the PFAS constituents being evaluated; I = represents total number of PFAS constituents included in the summation of Total PFAS concentrations; MDp,i = mass load of each PFAS constituent i from each potential pathway p with measured units in mass per unit time [MT-1], typically mg/s; Cp,i = concentration of each PFAS constituent i from each potential pathway p with measured units in mass per unit volume [ML-3], typically ng/L; and Qn = volumetric flow rate from each potential pathway n with measured units in volume per time [L3T-1], typically liters per second (L/s). Calculation of Time-Weighted Average Concentrations During a time period, multiple samples will be collected, most of them being composite samples and some potentially being grab samples. The calculation methodology outlined here considers all collected samples in the time period, including cases where samples are collected contemporaneously with each other and cases where composite sample collection events do not occur successively, as is the case with twice weekly 24 hour composite samples. To facilitate this calculation the overall time period is separated into discrete time intervals with corresponding time-weighted concentrations calculated for each interval. The time intervals are defined as the duration in time between two sampling events, where sampling events consist of: •Beginning of a composite sample collection; •End of a composite sample collection; or •Collection of a grab sample. Equation 3 shows the formula used to calculate the total flow volume for each interval.

For composite samples, 𝑡𝑡𝑘𝑘 is the total length of the composite sample collection period. If 𝑡𝑡𝑘𝑘<𝑡𝑡𝑛𝑛, i.e., the composite sample collection time is less than the interval time, or a grab sample was collected, then 𝑡𝑡𝑘𝑘 is set to equal the interval time for the purposes of concentration weighting. Calculation of Travel Time Adjusted Flow Volumes To calculate the mass load, river flow volumes are calculated for each time interval using United States Geological Survey (USGS) reported flows at the W.O. Huske Dam. A time offset is applied to the flow data to account for travel time for the flow passing the W.O. Huske Dam to reach the CFR-TARHEEL location. River flow passing the W.O. Huske is estimated to have a travel time between 2 and 12 hours to reach CFR-TARHEEL depending on river flow (e.g., the flow rate passing W.O. Huske Dam at 8 am will arrive at CFR-TARHEEL at 11 am for a 3 hour travel time). Travel times are estimated based on the results of a numerical model of the Cape Fear River which developed a regression curve between the USGS reported gage heights at W.O. Huske Dam and travel times. Equation 4 shows the formula used to calculate the time offset. The total volume of flow for each mass loading interval is calculated as the sum of all individual flow measurements Appendix B 4 March 2021 for an interval where each measurement multiplied by its corresponding 15-minute time duration. Equation 5 shows the formula used to calculate the total flow volume for each interval. Equation 4: Travel time offset W.O.

Huske Dam for a given point in time in cubic feet per second (ft3/s); and 13,422 𝑎𝑎𝑛𝑛𝑎𝑎 2.019 = are constant values, which correspond to the slope and intercept of the regression line, respectively.

The specific methodology for estimating the prevented mass per remedy will be developed on a per remedy basis. The goal of such calculations will be to estimate for a given time period (i.e. one quarter) the PFAS mass diverted from reaching the Cape Fear River by the remedy that would have otherwise reached the Cape Fear River. Remedies that have been implemented by Chemours include the Old Outfall 002 treatment system (October 1, 2020) and the Seep C flow through cell (December 16, 2020). These remedies prevent PFAS mass loads from reaching the Cape Fear River and were quantified in the 𝑚𝑚𝐶𝐶𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 term of Equation 1. The following subsections describe the calculation methodology for the captured mass load by The Old Outfall 002 treatment system and the Seep C flow-through cell. There have been numerous other interim and permanent actions taken to limit PFAS reaching the Cape Fear River prior to this baseline period, i.e., air abatement measures (installation of the thermal oxidizer and carbon beds, etc.), grouting of the terracotta pipe, sediment removal from channels, among others, and these may not be captured in this captured mass load calculation but should be considered in the overall assessment of PFAS reductions. Calculation of Mass Captured at Old Outfall 002 Treatment System During the 2020 Q4 reporting period (October to December 2020) the Old Outfall 002 treatment system began to discharge treated water on October 1, 2020.

Due to file size limits, analytical laboratory reports will be provided separately. Reanalyzed Samples Analysis of the samples from CFR-TARHEEL collected on November 24, 2020 (CFR- TARHEEL-24-112420) and November 26, 2020 (CFR-TARHEEL-24-112620) provided initial results that were significantly different from prior data (SDG 320-67335-1). The sample from November 24, 2020 was non-detect for HFPO-DA while the sample from November 26, 2020 was the highest result for HFPO-DA observed in 2020 (see Table 7 in the main section of the report). Further examination of the samples indicated that they contained a layer of sediment in the sample bottle. In addition, the sample from November 26, 2020 had a yellow color. These heterogeneities could lead to inconsistent results if, for example, different amounts of sediment were in the subsamples taken for analysis from the samples. The retained samples were re- extracted and re-analyzed in March 2021 and these second results were used in the mass loading calculations (SDG 320-67335-2). Analysis of the sample from CFR-MILE-76 collected on December 15, 2020 provided a PMPA result (23 ng/L) that was close to the reporting limit (20 ng/L) (SDG 320-68082-1). The retained sample was re-analyzed using the Table 6 method, which provides a lower reporting limit (2 ng/L) for PMPA and therefore more reliable results for low concentration samples. This second PMPA result (6.3 ng/L) was used in the mass loading calculations (SDG 320-68082-3).

ADQM Data Review Checklist Item Description Yes No* DVM Narrative Report Laboratory Report Exception Report (ER) # A Did samples meet method acceptability requirements upon receipt at the laboratory (i.e., temperature, preservation, headspace, broken bottles)? X B Were samples received by the laboratory in agreement with the associated chain of custody? X C Was the chain of custody properly completed by the field team? X D Were all samples prepped/analyzed within method holding times? X E Were method QA/QC criteria met by the laboratory for all samples (i.e., blanks, LCSs/LCSDs, MSs/MSDs, PDSs, SDs, duplicates/replicates, surrogates, total/dissolved differences, dual column RPDs) X X F Were all field/equipment/trip blanks (if collected) detected at levels not requiring sample data qualification? X X G Were all reported results within the laboratory’s calibration range? X ER# Description Other QA/QC Items to Note: 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 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. 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. The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. * See DVM Narrative Report, Lab Report, or ER # for further details as indicated. 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)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/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. If the data has been validated by a third party, the field “Validated By” will be set to the validator (e.g., ESI for Environmental Standards, Inc.). DVM Narrative ReportThe analysis hold time for this sample was exceeded by a factor of 2. The reported result may be biased low.LABSTATSValidation Options:Validation ReasonFayettevilleSite:Sampling Program:CAP SW Sampling 12/20AnalyticalMethodAnalyteDateSampledPQLValidationQualifierLab Sample IDPre-prepMDLResultTypeField Sample IDPrepUnitsCAP1220-CFR-RM-76-12152012/15/2020320-68082-1NVHOS0.0020UG/LCl.

ADQM Data Review Checklist Item Description Yes No* DVM Narrative Report Laboratory Report Exception Report (ER) # A Did samples meet method acceptability requirements upon receipt at the laboratory (i.e., temperature, preservation, headspace, broken bottles)? X B Were samples received by the laboratory in agreement with the associated chain of custody? X C Was the chain of custody properly completed by the field team? X D Were all samples prepped/analyzed within method holding times? X E Were method QA/QC criteria met by the laboratory for all samples (i.e., blanks, LCSs/LCSDs, MSs/MSDs, PDSs, SDs, duplicates/replicates, surrogates, total/dissolved differences, dual column RPDs) X X F Were all field/equipment/trip blanks (if collected) detected at levels not requiring sample data qualification? X X G Were all reported results within the laboratory’s calibration range? X ER# Description Other QA/QC Items to Note: 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 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. 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. The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. * See DVM Narrative Report, Lab Report, or ER # for further details as indicated. 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)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/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. If the data has been validated by a third party, the field “Validated By” will be set to the validator (e.g., ESI for Environmental Standards, Inc.).

The Cape Fear River stage is lower than the top of the Black Creek Aquifer, except during peak rainfall or flooding, indicating that the Cape Fear River is a discharge boundary for the aquifer. Onsite groundwater from the Black Creek Aquifer discharging to the Cape Fear River is therefore a potential pathway for per- and polyfluoroalkyl substances (PFAS) mass loading to the Cape Fear River. This pathway was identified as Transport Pathway Number 5 in the PFAS mass loading design in this report. The objective of the supporting calculations presented in this appendix is to estimate PFAS mass loading from onsite groundwater discharge based on calculated PFAS mass flux for segments of the Black Creek Aquifer along the river frontage. APPROACH The PFAS mass loading from onsite groundwater discharge was estimated as follows. Supporting data are provided in Table G1: 1. The Cape Fear River frontage was divided into 8 segments (Figure G1). Each segment includes one groundwater monitoring well that is considered representative of the Black Creek Aquifer and that is included in the Corrective Action Plan1 (Geosyntec, 2019b). 2. The thickness of the Black Creek Aquifer (h) was estimated for each segment based on the segment length and the cross-sectional area of the Black Creek Aquifer, as determined by the three-dimensional hydrostratigraphic model of the Site, constructed using CTech’s Earth Volumetric Studio (EVS) software (Geosyntec, 2019b): ℎ = 𝐴 𝑙 where h is the Black Creek Aquifer thickness [ft]; A is the cross-sectional area of the Black Creek Aquifer [ft2]; and l is the segment length [ft]. The EVS model output for each segment is presented in Figure G2. 1 The Black Creek Aquifer is not observed in boreholes from Segment 4 suggesting a localized "pinch-out" of the Black Creek Aquifer in Segment 4. The monitoring well used to determine PFAS mass loading in this segment is screened in the Floodplain Deposits (LTW-03). Appendix G 2 March 2021 3.The hydraulic gradient (i) was derived based on the groundwater level contour map. For each segment, two gradients were estimated based on the distance between two sets of contour lines in the vicinity of the river frontage (Figure G3): 𝑖= 𝛥ℎ 𝑑 where i is the hydraulic gradient [ft/ft]; Δh is the head difference between two contour lines [ft]; and d is the estimated distance between the contour lines [ft] For each segment, a range of hydraulic gradients was calculated using two different contour elevation differences in the vicinity of the river frontage: a ten-foot elevation difference (between the 40 and 50 ft contours) and a twenty-foot elevation difference (between the 40 and 60 ft contours). Using two contour elevation differences captures the variation in hydraulic gradient estimates over a range of spatial scales. This approach is considered to best represent the likely groundwater fluxes discharging from the Black Creek Aquifer to the Cape Fear River. Based on hydrographs from wells along the river presented in Figure G4 hydraulic gradients in the aquifer are relatively constant over time. With the exception of large changes in the river level (over ten feet), these wells respond to river level fluctuation in a subdued manner. 4.The hydraulic conductivity (K) was estimated for each segment using the results of constant rate tests performed at five extraction wells installed in the Black Creek Aquifer upstream of the river frontage. The extraction wells used to determine the hydraulic conductivity for each segment are as follows, based on their locations relative to the segments (Figure G5): Extraction Well Segment EW-1 1 2 EW-4 3 4 EW-5 5 6 EW-2 7 EW-3 8 Appendix G 3 March 2021 5.The total PFAS concentration for each segment was determined based on grab samples collected from monitoring wells. PFAS analytical results for these groundwater samples are presented in Table 10 of this report. The monitoring well located in Segment 8 (PW- 11) was inaccessible during the Q4 2020 monitoring event due to ongoing aquifer testing at this location, so it was not sampled. PFAS analytical results obtained from PW-11 during the Q3 2020 monitoring event were used to determine mass loading for Segment 8. 6.Mass flux for each segment, representing the PFAS mass loading to the river from groundwater, was determined as follows: 𝑄=𝑙ℎ𝐾𝑖𝐶𝑓 where Q is the mass flux [mg/sec]; l is the segment length [ft]; h is the Black Creek Aquifer thickness [ft]; K is the hydraulic conductivity of the aquifer [ft/sec]; i is the hydraulic gradient [ft/ft], using an upper and lower contour elevation difference; C is the total PFAS concentration [ng/L]; and f is the conversion factor between cubic feet and liters and between ng and mg. 7.The upper and lower bound of the total mass flux for the groundwater pathway was calculated as the sum of the individual mass flux results for the 8 segments. Parameters listed above were also used to estimate groundwater flow rates, shown in Table G2. 8.Passive flux meters deployed in select monitoring wells during the Pre-Design Investigation (Figure G5) were used to assess groundwater velocity and Table 3+ PFAS flux (in mass per distance per time) along potential groundwater discharge paths to Willis Creek and the Cape Fear River. PFM-derived PFAS flux was used to estimate mass flux in each segment as follows: 𝑄=𝑙ℎ𝑗𝑓 where Q is the mass flux [mg/sec]; l is the segment length [ft]; h is the Black Creek Aquifer thickness [ft]; j is the PFAS flux determined from the PFMs [µg/m2/day]; and f is the conversion factor between meters and feet, days and seconds, and ng and mg. Appendix G 4 March 2021 The mass flux determined using the PFMs was used to compare against the mass flux determined by the method described in this appendix. Table G3 provides the PFAS flux and mass flux results determined using the PFMs. While the mass flux results from both methods are expected to be similar, variations exist in the source data for both methods such that some variation in the calculated mass flux may be expected. First, the PFMs were deployed in October 2020 while the groundwater samples were collected in December 2020. Second, the wells where PFMs were deployed do not necessarily correspond to the wells where groundwater samples were collected. The wells where PFMs were deployed are located in the vicinity of each segment. No PFMs were deployed in wells in Segment 5, so the average PFAS flux for segments 4 and 6 were used to calculate mass loading in this segment.

These pathways include direct PFAS aerial deposition to the Cape Fear River. This pathway was identified as Transport Pathway Number 3 in the PFAS mass loading model. The mass discharge (mass per unit time measured in milligrams per second [mg/s]) from direct aerial deposition of PFAS to the Cape Fear River was estimated by scaling air deposition modeling results for Hexafluoropropylene oxide dimer acid (HFPO-DA; ERM, 2018). The objective of the supporting calculations presented in this appendix is to estimate aerially deposited PFAS directly on the Cape Fear River during a mass loading event. APPROACH HFPO-DA mass loading directly to the Cape Fear River was estimated using the reported aerial extent and deposition contours modeled for October 2018 (ERM, 2018). As depicted in (Table H1), the HFPO-DA air loading data (micrograms per meters squared [µg/m2]) provided from ERM (2018) was used to calculate the net hourly deposition rate (nanograms per meters squared per hour [ng/m2/hr]) using the Equation 1 below: Equation 1: Net Hourly Deposition Rate 𝐷𝑅ோ் ൌ 𝑀𝐿஺ூோ 𝑡஺ூோ where: 𝐷𝑅ோ் = Net hourly deposition rate with units of mass per area per time (M L-2 T-1), typically in ng/m2/hr; 𝑀𝐿஺ூோ = Air mass loading of HFPO-DA with units of mass per area (M L-2), typically µg/m2; and 𝑡஺ூோ = time that air mass loading was modeled (T), typically hours. Depositional area along the river was calculated using available data for river width and computed river lengths where deposition contours were modeled. Eighteen (18) sections (Figure H1) provided from FEMA (2007) were selected along the Cape Fear River to measure the average river width (m). As depicted in Figures H2 through H6, sections along the Cape Fear River with HFPO- DA concentrations contours ranging from 40 to 640 µg/m2 were selected, and the length of the Cape Fear River along each of the sections was measured. The average river width calculated in Table H2 and section lengths from Figures H2 through H6 were used to calculate section areas (m2) as described in Equation 2 below: 2 March 2021 Appendix H Equation 2: Cape Fear River Surface Area for Each Section 𝐴௦ ൌ𝐿௦ ൈ𝑊௦ where, 𝐴௦ = total spatial area over which deposition occurs between contours (L2) in section “s”, typically in m2; s = section along the Cape Fear River with HFPO-DA concentrations contours ranging from 40 to 640 µg/m2 (five sections in total); 𝐿 = total length of river within section “s”, typically in m; and 𝑊௦ ൌ average river width in section “𝑠”,typically in m. Start and end deposition rates (ng/m2/hr) for each section along the Cape Fear River will be estimated based on the deposition contours and corresponding net hourly deposition rate (Table H1); a combined deposition rate for each section will be calculated as the average of the start and end deposition rates. River velocity (meters per hour [m/hr]) will be estimated from measured flow rates from USGS (2020) and the calculated river cross sectional area. Section lengths will be used to calculate HFPO-DA travel time based on the river velocities in Table H3. The combined deposition rate (ng/m2/hr) from Table H1, section area (m2), and travel time (hr) will be used to calculate mass HFPO-DA deposited (ng) as follows in Equation 3 below. Equation 3: Total HFPO-DA Mass Discharge to Cape Fear River 𝑀𝐷ுி௉ைି஽஺ ൌ෍𝐷𝑅஺௏ீ,௦ ൈ 𝐴௦ ൈ 𝑡௦ ௌ ௦ୀଵ where, 𝑀𝐷ுி௉ைି஽஺ = total mass discharge of HFPO-DA into the river across all sections, with units of mass per time (M T-1), typically mg/s; s = section along the Cape Fear River with HFPO-DA concentrations contours ranging from 40 to 640 µg/m2; S = total number of sections along the Cape Fear River with HFPO-DA concentrations contours ranging from 40 to 640 µg/m2, five in total; 𝐷𝑅஺௏ீ,௦ = average deposition rate based from the ERM model (2018) in section “s”, typically in ng/m2/hr; 𝐴௦ = spatial area over which deposition occurs in section “s”, typically in m2; and 𝑡௦ = travel time through the river length in section “s”, typically in hr. As reported in the Corrective Action Plan (Geosyntec 2019), ten offsite groundwater seeps south of Old Outfall 002 (Seeps E to M) were identified on the west bank of the Cape Fear River south of the Site. Seeps E to M were sampled in October 2019 and Seeps E to K were sampled in March Appendix H 3 March 2021 2020 and analyzed for PFAS. The results of both sampling events indicate that Seeps E to M show an aerial deposition PFAS signature (concentrations decrease in seeps more distant from the Site). Accordingly, the offsite seep data were used to build a relationship between HFPO-DA and other PFAS compounds (Figure H7). A scaling factor (Table H4) was used to estimate mass discharge of Total PFAS compounds to the Cape Fear River as shown in Equation 4. Table H5 shows the estimated mass discharges of HFPO-DA and Total PFAS compounds to the Cape Fear River. Equation 4: Total PFAS Mass Discharge to Cape Fear River 𝑀𝐷௉ி஺ௌ ൌ 𝑀𝐷ுி௉ைି஽஺ ൈ 𝑅 where, 𝑀𝐷௉ி஺ௌ = total mass discharge of PFAS compounds into the river, typically in mg/s; 𝑀𝐷ுி௉ைି஽஺ = total mass discharge of HFPO-DA into the river, typically in mg/s; and 𝑅 = average ratio of measured HFPO-DA to PFAS compounds across the nine offsite seeps.

PFAS detected in offsite groundwater originate from aerial deposition which has occurred in all directions from the Site (CAP Geosyntec, 2019g). These aerially deposited PFAS have subsequently infiltrated to groundwater and migrate towards the Cape Fear River where they lead to upstream, adjacent and downstream offsite groundwater PFAS mass. The upstream offsite groundwater PFAS mass discharge is estimated relatively simply by using measured river flows and concentrations at River Mile 76 upstream of the Site. Here only the upstream offsite groundwater PFAS mass discharge is present in the river at this location. Conversely, the adjacent and downstream offsite groundwater PFAS mass discharge is difficult to measure directly since many PFAS mass discharges from all other pathways are present in the river where these offsite groundwater contributions join the river. Additionally, downstream offsite groundwater has a relatively small component of the Total PFAS mass discharge making its additional contributions to the total discharge difficult to distinguish from other discharges already present. Therefore, since PFAS mass discharge from offsite groundwater upstream, adjacent, and downstream of the Site follow the same dynamics (deposition, infiltration, migration, discharge) the adjacent and downstream PFAS mass discharge is scaled from the upstream offsite groundwater mass discharge estimate. The downstream offsite groundwater loadings are scaled to the upstream offsite groundwater loadings based on the length of river adjacent and downstream of the Site known to be in contact with offsite groundwater containing PFAS compared to the length of the river upstream also in contact with offsite groundwater containing PFAS. The volume of river flow is assumed to be constant immediately upstream and downstream of the Site for the purposes of this calculation. This adjacent and downstream offsite mass discharge is calculated using Equation 1 below: Equation 1: Total Mass Discharge Adjacent and Downstream Offsite Groundwater 𝑀𝐷௔ௗ௝ିௗି௚௪ ൌ ෍൫𝐶௨௣ି௚௪,௜ ൈ𝑄஼ிோ൯ ൈ𝑓௔ௗ௝ିௗ ூ ௜ୀଵ where, 𝑀𝐷௔ௗ௝ିௗି௚௪ = represents the Total PFAS discharge from adjacent and downstream offsite groundwater to the Cape Fear River, units in mass per unit volume [ML-3], typically milligram per second; i = represents each of the PFAS constituents listed in Table I1; Appendix I 2 March 2021 I = represents total number of PFAS constituents included in the summation of Total PFAS concentrations; 𝐶௨௣ି௚௪,௜ = represents the upstream concentration of each PFAS constituent i from measured units in mass per unit volume [ML-3], typically nanograms per liter; 𝑄஼ிோ = represents the volumetric flow in the Cape Fear River as reported by the United States Geological Survey gage at the W.O.
