November 2019 EXECUTIVE SUMMARY Geosyntec prepared this Ecological Screening Level Exposure Assessment (Ecological SLEA) on behalf of The Chemours Company FC, LLC (Chemours) in support of developing a Corrective Action Plan (CAP) for the Chemours Fayetteville Works Site (the Site). The overall goal of the Ecological SLEA was to refine the ecological Conceptual Site Model in support of CAP development, quantify and assess exposures to ecological receptors onsite, offsite and in the Cape Fear River, and to evaluate the potential for hazards related to exposure to hexafluoropropylene oxide dimer acid (HFPO-DA). Field investigations included collection of onsite and offsite soils, invertebrates and offsite vegetation, and sediment, vegetation, fish and clams from the Cape Fear River for analysis of Table 3+ per- and poly-fluoroalkyl substances (PFAS). These data were used to evaluate the presence of Table 3+ PFAS in environmental media, identify spatial patterns, quantify mammalian and avian exposures to Table 3+ PFAS, and to evaluate the potential for adverse effects to wildlife from current exposures to HFPO-DA. Overall, 17 out of 20 Table 3+ PFAS were detected in one or more samples from the field investigation. Environmental media with the highest number of positively detected Table 3+ PFAS included site invertebrates (15 out of 20), onsite soils (13 out of 20), terrestrial vegetation (13 out of 20), aquatic vegetation (11 out of 20), and fish (7 out of 20). However, some environmental media had very few or no detections of Table 3+ PFAS, including sediment (in which only HFPO-DA was detected), offsite soil (2 out of 20 Table 3+ PFAS were detected) and benthic invertebrates from the Cape Fear River (in which no Table 3+ PFAS were detected). Because the sediment in the Cape Fear River and soil in the offsite areas do not appear to have accumulated widely detectable concentrations of Table 3+ PFAS, they are not likely to act as long-term exposure sources for ecological receptors, although uncertainties regarding partitioning to porewater and analytical sensitivities remain. Estimated total daily intake (TDI) indicated that the highest Table 3+PFAS exposures are for vertebrates that consume terrestrial and aquatic plants in both onsite, aquatic and offsite areas. In general, herbivores demonstrated a higher estimated TDI for Table 3+ PFAS, followed by piscivores and invertivores. Estimated total exposures (i.e., cumulative exposure to all Table 3+ PFAS) were generally highest in the onsite area, exceeding those in the Cape Fear River and offsite terrestrial areas by up to 3 times. The predominant Table 3+ PFAS contributing to herbivore exposures included perfluoro-2- methoxyacetic acid (PFMOAA), sodium 1,1,2,2-tetrafluoro-2-(1,2,2,2- tetrafluoroethoxy)ethane-1-sulfonate (NVHOS), perfluoro-2-(perfluoromethoxy)- propanoic acid (PMPA) and perfluoro-3,5-dioxahexanoic acid (PFO2HxA). Piscivores TR0795 2 December 2019 in the Cape Fear River were exposed to a high proportion of PFMOAA and perfluoro(3,5,7,9-tetraoxadecanoic) acid (PFO4DA). Exposure to invertivores included PFMOAA, PMPA, Byproduct4, Byproduct5, and HFPO-DA. Hazard quotients (HQs) for HFPO-DA ranged from 0.00000008 to 0.24, indicating that current exposures in these Exposure Units (EUs) are not expected to pose a hazard to ecological receptors. Although there are several inherent sources of uncertainty in ecological evaluations, the primary source of uncertainty in the Ecological SLEA is attributed to the lack of toxicity reference values (TRVs) for many Table 3+ PFAS, as TRVs are a key element of quantitative hazard evaluations. Chemours is presently undertaking a process to provide additional toxicity data for five additional compounds (PMPA, PEPA, PFMOAA, PFO2HxA, and PFESA-BP2), which will be useful in the development of TRVs in the future. Tests are presently anticipated to be completed in late 2022. Overall, this Ecological SLEA presents a screening-level evaluation of Table 3+ PFAS detected in environmental media. Results indicate that current exposures to ecological receptors from HFPO-DA are not expected to pose a hazard to ecological receptors in the study area. TR0795 3 December 2019 1 INTRODUCTION Geosyntec prepared this Ecological Screening Level Exposure Assessment (Ecological SLEA) on behalf of The Chemours Company FC, LLC (Chemours) in support of developing a Corrective Action Plan (CAP; Geosyntec, 2019a) for the Chemours Fayetteville Works Site (the Site) pursuant to the February 25, 2019 Consent Order (CO) among the Chemours Company FC, LLC (Chemours), the North Carolina Department of Environmental Quality (NCDEQ) and the Cape Fear River Watch. While inclusion of this Ecological SLEA is not a requirement of the CO, Chemours has performed this evaluation of exposure to ecological receptors for Table 3+ per- and polyfluoroalkyl substances (PFAS) to support the CAP. This Ecological SLEA evaluated exposures of Table 3+ PFAS to ecological receptors and the hazard potential for hexafluoropropylene dimer acid (HFPO-DA), as toxicological data are only available for HFPO-DA. The remainder of this section focuses on a brief overview of the Ecological Risk Assessment (ERA) process, as well as specific goals and objectives for this assessment. 1.1 Ecological Exposure and Risk Assessment This subsection contextualizes the data and analyses described herein within the ERA process. The purpose of performing an ERA is to identify and characterize the current potential risks to ecological receptors from potentially hazardous substances. Additionally, ecological risk assessments can be used to establish cleanup levels protective of ecological receptors and evaluate various remedial approaches (USEPA, 1994; NCDEQ, 2003). USEPA guidance on performing ERAs includes an 8-Step process concluding with a Scientific Management Decision Point (SMDP). Screening-level ecological risk assessments (SLERA) consistent with standard ecological risk assessment practice and guidance (USEPA, 1993; NCDEQ 2003), are reflective of the first two steps of this 8-Step ERA framework. A SLERA applies conservative assumptions, often using more limited data sets, to evaluate the potential hazards to ecological receptors. SLERAs include the following key steps: •Problem Formulation and Toxicity Evaluation: In this first step of the SLERA process, information regarding the Site is compiled. Information evaluated in this step can include on and offsite habitats, identifying potentially exposed receptors including state or Federally listed species, and identifying potentially complete exposure pathways. Additionally, toxicity benchmarks are selected, typically in the form of conservative screening levels developed by State or Federal agencies. These screening levels are typically based on TR0795 4 December 2019 highly conservative assumptions and are reflective of concentrations in the environment below which no adverse impacts to receptors are expected. •Screening-level Exposure Assessment and Risk Calculations: In this second step of the SLERA, the exposure to receptors is estimated using conservative assumptions. For example, maximum concentrations of constituents may be selected over measures of central tendency to reflect exposure point concentrations. The estimated exposure is compared to the toxicity benchmark selected in Step 1 to evaluate the potential for risk. If exposure is below the toxicity benchmark, it can be confidently concluded that adverse impacts are not likely to occur. If exposure is greater than the toxicity benchmark, then additional refinement of assumptions and quantification of risk levels should be considered. Due to the emerging nature of Table 3+ PFAS and the wider class of PFAS there are limited toxicity benchmarks to be applied to evaluate risks. For this reason, this report reflects a Screening Level Exposure Assessment rather than a SLERA. This Ecological SLEA includes the Problem Formulation and Exposure Assessment steps of a typical SLERA and evaluated hazard where sufficient toxicity data are available to do so. For Table 3+ PFAS, toxicity data are available for HFPO-DA. Under Paragraph 14 of the CO, Chemours is working to address many of the toxicity data gaps related to other Table 3+ PFAS (Chemours, 2019). The results of this Ecological SLEA may be refined as additional information on toxicity of these compounds becomes available. 1.2 Objectives The objective of this Ecological SLEA was to refine the ecological Conceptual Site Model (CSM) in support of developing the Corrective Action Plan (CAP). Prior to this Ecological SLEA, minimal data on the presence of Table 3+ PFAS in biotic media in the vicinity of the Site were available, resulting in limited understanding of the magnitude of exposure for ecological receptors to Table 3+ PFAS. While the current understanding of the toxicity of Table 3+ PFAS limits the ability to evaluate hazards, this Ecological SLEA followed standard SLERA methodologies with respect to Problem Formulation and Exposure Assessment and applied appropriately conservative assumptions at this stage. Specifically, the objectives of this Ecological SLEA are: •Evaluate the presence/absence of Table 3+ PFAS in abiotic and biotic media; •Quantify exposure to Table 3+ PFAS for terrestrial plants, invertebrates and wildlife, and aquatic life (pelagic fish, invertebrates, vegetation), benthic invertebrates and aquatic-dependent wildlife; TR0795 5 December 2019 •Refine the CSM and understanding of fate of Table 3+ PFAS in the foodweb; •Evaluate hazards related to exposure to HFPO-DA where sufficient understanding of toxicity is available; and •Evaluate additional lines of evidence to refine understanding of the CSM. TR0795 6 December 2019 2 SITE SETTING 2.1 Site Description The Site is located within a 2,177-acre property at 22828 NC Highway 87, approximately 15 miles southeast of the city of Fayetteville, NC along the Bladen-Cumberland county line. Figure 2-1 presents an overview of the Site. The Site is bounded by NC Highway 87 to the west, the Cape Fear River to the east, and by undeveloped areas and farmland to the north and south. Willis and Georgia Branch Creeks, which are tributaries of the Cape Fear River, are located near the northern and southern property boundaries respectively, with the Georgia Branch Creek being offsite for its entire course (Geosyntec, 2019b). Of the 2,177-acre property, approximately 400 acres is developed land for manufacturing activities, with the remainder generally undeveloped. The Site is zoned for industrial use but includes land specifically designated for conservation and provides habitat for deer, turkey, and other wildlife. A more robust Site history and other operations on Site are described in the Site Assessment Report (Geosyntec, 2019b). 2.2 Environmental Setting 2.2.1 Climate The climate in Bladen County is characterized by relatively mild winters, hot summers, and abundant rainfall. According to the National Weather Service, average monthly temperatures range from a high of 91 degrees Fahrenheit (°F) in July to a low of 33°F in January. Average monthly rainfall ranges from a high of 5.92 inches in July to a low of 2.65 inches in December (Parsons, 2014). 2.2.2 Topography The developed portion (manufacturing area) of the Site is located on a relatively flat topographic plateau at an approximate elevation of 145 feet above mean sea level (MSL) and approximately 70 feet above the Cape Fear River floodplain (Figure 2-2). Surface topography generally remains flat to the west with a gentle increase of about 5 feet to a topographic divide near NC Highway 87. However, ground surface elevations decrease from the topographic plateau at the manufacturing area towards the Cape Fear River to the east as well as its tributaries, Willis Creek to the north and Georgia Branch Creek to the south. Topographic relief from the main manufacturing area decreases by approximately 100 feet in elevation towards the Cape Fear River bank to the east. Inclined topographic relief combined with overland flow and groundwater seeps have created natural drainage networks into the Cape Fear River (Geosyntec, 2019b). TR0795 7 December 2019 2.2.3 Land Uses and Habitats The Site is situated along the Bladen and Cumberland county line and is within the Coastal Plain eco-region in North Carolina (NC) (NCWC, 2019). This region is classified by the prevalence of large rivers, reservoirs and impoundments, natural lakes, and stream swamp systems. The Cumberland County Land Use Plan Map indicates that the county is predominantly comprised of undeveloped lands with clusters of residential or manufactured homes. Based on the 2016 land use plan (CCJPB, 2016), Cumberland County is largely zoned for agricultural production due to the large proportion of land designated as either prime farmland (rich soil requiring little input of resources like chemicals or energy) or soil of state and local importance (capable of crop production with modern farming technology). These areas largely produce crops for food, fiber, feed, forage, and oilseed crops. Approximately 24,000 acres of land in Cumberland County were considered to be a part of working farms, either large commercial farms producing one crop (i.e. tobacco, grain crops, peanuts, cotton) or small, multiuse farms with both crops and livestock. There are also a number of working farms that identify as woodlands, or tree farms for future harvesting. This county also features wildlife species that are considered endangered, threatened, significantly rare, or of special concern as discussed below. Bladen County features many of the same attributes of Cumberland County. Bladen largely includes undeveloped land, land with agricultural use, and clusters of residential use. There are three rivers in the county, and it is bisected by the Cape Fear River which is the largest. Fishing, as well as deer and squirrel hunting are prominent recreational activities in the county. Bladen County includes the habitat for many of the same species as Cumberland County. 2.2.4 Cape Fear River and Tributaries The Cape Fear River and its entire watershed are located in the state of NC. The Cape Fear River drains about 9,164 square miles and empties into the Atlantic Ocean near the city of Wilmington, NC, and hosts a diverse ecosystem. Including tributaries, the Cape Fear River watershed extends over 200 miles in length, beginning in the Piedmont and ending in the Atlantic Ocean off the coast of Wilmington (NC Office of Environmental Education and Public Affairs, 2019). Habitats present over the course of the Cape Fear River include forests, wetlands, riparian areas, and estuaries. Endemic to the Cape Fear River is an endangered species known as the Cape Fear shiner, a minnow that lives in shallow, rocky areas. Historically, the Cape Fear River also has hosted healthy populations of sturgeon, bass, and American shad. TR0795 8 December 2019 However, the three lock-and-dam structures, historically used along the lower Cape Fear River to allow the larger vessels to navigate through shallow waters, may block passage of anadromous fish species. Along with overfishing and declining water and habitat quality, some species have recently been in decline (Cape Fear River Partnership, 2019). Other biota inhabiting the Cape Fear River include cypress trees, alligators, and otters, and many estuarine organisms are found along the 35 miles of the river between Wilmington and the Atlantic Ocean which also serves as a nursery for shrimp, crabs, and fish. The Site is situated on the western bank of the Cape Fear River and it draws water from the Cape Fear River for use primarily as non-contact cooling water. Three lock and dam systems with United States Geological Survey (USGS) stream gauges are located downstream of the Site: (1) W.O. Huske Lock and Dam, located 0.5 river miles from the Site; (2) Cape Fear River Lock #2 near Elizabethtown and (2) Cape Fear Lock and Dam #1, located 55 river miles downstream. There are three perennial surface water features that are tributaries to the Cape Fear River at or adjacent to the Site. To the north of the Site is Willis Creek, in close proximity to the water intake for the Site. To the south of the Site is Georgia Branch Creek which discharges to the Cape Fear River approximately 7,500 feet south of the W.O. Huske Dam. Old Outfall 002 discharges a mixture of surface water and groundwater into the Cape Fear River approximately 1,350 feet south of the W.O. Huske Dam (Geosyntec, 2019b). Additionally, in 2019 four groundwater seep features were identified on the hillside leading from the Site to the Cape Fear River between Willis Creek and Old Outfall 002. These seeps represent groundwater exiting the aquifer and forming channelized flows of water to the Cape Fear River. In the vicinity of the Site, livestock operations have the greatest effects on the natural resources and habitat quality along the river (Cahoon et al., 1999). The majority of swine are found in the Cape Fear River basin; large numbers of the total population of turkeys, chickens, and cattle are also found in the Cape Fear River basin. The result of livestock production is the introduction of large amounts of nutrients which has led to algal blooms, increased biological oxygen demand, and the threat of eutrophication. In addition to livestock, large industries lining the lower part of the Cape Fear River have impacted water quality via industrial discharges and stormwater runoff in this area. Particular to potential impacts from PFAS, both Fort Bragg in Fayetteville and Seymour Johnson Air Force Base in Goldsboro, NC have been identified as potential PFAS related impacted sites (EWG, 2019). Multiple studies (Nakayama et al. 2007; Sun et al. 2016; Lindstrom et al., 2015) have reported elevated concentrations of perfluorooctane sulfonate (PFOS) and other ‘legacy’ PFAS in the Cape Fear River watershed well upstream of the Cape Fear River and the Site, including the Haw River and Cane Creek Reservoir, resulting from a series of inputs regionally. While the majority Table 3+ PFAS TR0795 9 December 2019 enter the Cape Fear River adjacent to the Site, concentrations of ‘legacy’ PFAS, including perfluorocarboxylic acids (PFCAs) and perfluorosulfonic acids (PFSAs), are generally consistent upstream and downstream of the Site (Geosyntec, 2018). 2.3 Threatened & Endangered Species Threatened and endangered (T&E) species are receptors that receive special consideration in ecological risk and exposure assessments (USEPA, 1997). Populations of T&E species may be more vulnerable than other species to site-specific constituents, if present at a site, as smaller populations are less resilient to additional stressors. A comprehensive search for Federal- and state-listed species of special concern was conducted and included the following sites: -U.S. Fish & Wildlife Service. Raleigh Ecological Services Field Office. Endangered Species, Threatened Species, Federal Species of Concern, and Candidate Species, Cumberland County and Bladen County, NC. (https://www.fws.gov/raleigh/species/cntylist/cumberland.html and https://www.fws.gov/raleigh/species/cntylist/bladen.html) -Center for Biological Diversity, Map: U.S. Threaten and Endangered Species by County; Bladen County and Cumberland County considered (https://www.biologicaldiversity.org/programs/population_and_sustainability/T_ and_E_map/) -U.S. Fish & Wildlife Service. Information for Planning and Consultation tool (https://ecos.fws.gov/ipac/location/index) Table 2-1 presents a list of threatened, endangered, or otherwise at-risk species identified in Bladen and Cumberland Counties. This includes 10 vertebrates, 3 invertebrates and 9 vascular plant species. Table 2-1 also includes an evaluation of the preferred habitat for each species and an indication of whether these species are likely to be found within the Site, based on their habitat preferences. Many of the species identified as T&E species in Cumberland County are found only in the Northwestern portion of the county, distant from the Site, in an area called the Sandhills, which is near the Fall line. Based on this assessment, 4 vertebrates (i.e., Bald eagle, red cockaded woodpecker, Southern hognose snake, and wood stork), 2 invertebrates (Atlantic pigtoe [mussel], and variegated clubtail [sanddragon]), and 7 plant species (bog spicebush, Boykin's lobelia, Carolina bogmint, Michaux's sumac, pondberry, rough-leaved loosestrife, Venus’ fly-trap) are considered T&E or at risk and may potentially be found within the Site boundaries; a biological survey would need to be conducted to confirm the presence or absence of these species and/or their preferred habitat. As described in the following section, with the exception of the Southern hognose snake, Table 3+ PFAS exposure to each of these species is TR0795 10 December 2019 represented by a sensitive receptor from the same group of organisms (i.e., plant, terrestrial invertebrate, aquatic invertebrate, invertivorous terrestrial bird, piscivorous bird). 2.4 Conceptual Site Model 2.4.1 Table 3+ PFAS The primary PFAS of concern is HFPO-DA and the other Table 3+ PFAS that are formed in the manufacturing process at the Site. The list of Table 3+ PFAS is provided in Table 2-2 and Table 2-3 presents physical and chemical properties for each Table 3+ PFAS. This section primarily focuses on HFPO-DA as more is currently known on the physical and chemical properties, but inferences from the available data on the other Table 3+ PFAS are discussed below. HFPO-DA is a human-made chemical produced at the Site. HFPO-DA is a six carbon, branched PFAS containing an ether bond (i.e., an oxygen atom linking two carbon atoms). HFPO-DA is a clear, colorless liquid that exhibits a low octanol-water partitioning capacity (reported log Kow values range from 3.6 [Hopkins et al., 2018] to 4.26 [Geosyntec, 2019a])1 and is completely miscible with water (i.e., high solubility in surface water, groundwater, rainwater, leachate). Under normal environmental conditions, HFPO-DA exists as an anionic acid (2.8 acid dissociation constant [pKa])2 (Hoke et al., 2016). Similar to other environmentally persistent compounds, HFPO-DA has a relatively long half-life in environmental matrices (> 6-months) and does not readily undergo photolysis, hydrolysis, or biotransformation/degradation (USEPA, 2018; DuPont, 2008b; DuPont, 2009a). Due to a combination of high solubility in water and low affinity for sediment/soil, HFPO-DA is expected to rapidly partition to, and remain in aqueous environmental compartments (e.g., groundwater and surface water) (USEPA, 2018, DuPont, 2008a, Hoke et al., 2016, Beekman et al., 2016, Pan et al., 2018). However, the vapor pressure of HFPO-DA does not exclude some volatilization to air; dissolution in aerosolized water droplets or binding to suspended particulate matter has also been reported (USEPA, 2018). HFPO-DA present in air is deposited via wet and dry deposition (USEPA, 2018; Hoke et al., 2016; Beekman et al., 2016; Xiao et al., 2017). Once present 1 Kow is the octanol-water partitioning coefficient, the ratio of the equilibrium concentration of a dissolved chemical in a two-phase system of n-octanol and water. n-Octanol serves as a surrogate to biota lipids and Kow values are used as an indicator of a chemical’s tendency to bioaccumulate, or to be taken-up by organisms from the environment. 2 The pKa predicts that HFPO-DA will be in acid form (as a negative ion, or an anion) at pH levels at or above a pH of 2.8. TR0795 11 December 2019 in terrestrial systems, HFPO-DA is expected to rapidly partition to aqueous matrices via leaching and/or runoff (USEPA, 2018; Beekman et al., 2016; DuPont, 2008c). Structural analyses indicate a low bioaccumulative potential for both HFPO-DA anion and its ammonium salt relative to longer chain PFAS (e.g., PFOS and PFOA) (USEPA, 2018). These findings are supported by a limited number of bioaccumulation and bioconcentration studies in which aquatic biota are exposed to HFPO-DA (USEPA, 2018; DuPont, 2009b; DuPont, 2007; Hoke et al., 2016; Beekman et al., 2016, Xiao, 2017). Multiple fish studies have confirmed bioconcentration factors (BCFs) of less than 30 liters per kilogram (L/kg) wet weight (ww) (DuPont, 2009b; Hoke et al., 2016; Goodband, 2019). Bioaccumulation factors (BAFs), calculated for carp, were 7.2 L/kg ww for blood, 3.2 L/kg ww for liver and 4.0 L/kg ww for muscle (Pan et al., 2017). BCFs and BAFs greater than 5,000 L/kg ww are considered indicative of high bioaccumulation potential in aquatic food webs; BAFs and BCFs for HFPO-DA are well below this benchmark. Recent research has also shown rapid elimination (< 24 hours) and a lack of bioaccumulation of HFPO-DA in the benthic fish Blue spot gobies (Pseudogobius sp.) as no HFPO-DA was detected in fish tissue in either the uptake or elimination phases of this study (Hassell et al. 2019). While there are limited studies on the fate and transport of other Table 3+ PFAS, some general inferences can be drawn from the available understanding of PFAS as a class of compounds and the physical and chemical properties for each specific Table 3+ PFAS (Table 2-3): •Due to the strong nature of the C-F bond, while some compounds may degrade to daughter products, many compounds will be persistent in the environment or transform into persistent compounds. •Log10-based organic carbon-water partitioning co-efficient (log KOC) values range from 0.89 to 2.56 L/kg (Table 2-3; Geosyntec, 2019a), with HFPO-DA exhibiting a mid-range log KOC value of 1.69 L/kg (Table 2-3). The range of log KOC values observed for Table 3+ PFAS indicate that some compounds (e.g., Hydro-EVE Acid, EVE Acid) are more likely to partition to soils than others (e.g., Difluoro(perfluoromethoxy)acetic acid [PFMOAA]). Relative to compounds that strongly partition to organic matter in soils and sediments (e.g. PCBs with log KOC values in the 4 to 7 L/kg range), the log KOC values of Table 3+ are low, exhibiting values that are similar to less sorbtive compounds (e.g., benzene [log KOC = 1.77] or trichloroethylene [log KOC = 2.22]). •Predicted log10-based octanol-air partitioning co-efficient (log KOA) values range from 2.59 to 7.17. Log KOA values in the 5 to 7 range may be indicative TR0795 12 December 2019 of chemicals that exhibit potentially significant bioaccumulation potential in terrestrial (air-breathing) food-webs (Kelly et al. 2007). HFPO-DA has mid- range log KOA value of 3.74. •Bioconcentration factors (L/kg, ww) ranged from 1.4 to 617 L/kg ww, all well below the generally accepted benchmark of 5000 L/kg, ww indicative of high bioaccumulation potential in aquatic food-webs (Gobas et al., 2009). •Log partitioning coefficient (log P) is a commonly used measure of lipophilicity and is the partition coefficient of a molecule between aqueous and lipophilic phases. Log P is analogous to log octanol-water partitioning coefficient (log KOW), but it is used for ionic rather than neutral compounds. Log P values (at a pH of 8) ranged from 1 to 5.7 (Geosyntec, 2019a). For traditional persistent organic pollutants [polychlorinated byphenyls (PCBs), dichlorodiphenyltrichloroethane (DDTs)] where the primary mechanism for bioaccumulation is the preferential partitioning of compounds in lipids and a lack of metabolism, KOW can be a valuable metric to understand bioaccumulation potential; PFAS do not bioaccumulate by this mechanism. The current understanding of PFAS accumulation mechanisms relates to preferential partitioning in proteins rather than lipids, therefore logP or log KOW may not be a representative metric for bioaccumulation potential for PFAS (Conder et al., 2008). 2.4.2 Ecological Exposure Units For purposes of this Ecological SLEA, the Site and surrounding area where ecological receptors may be exposed to Table 3+ PFAS was divided into three ecological exposure units (EUs; Figure 2-3). 2.4.2.1 Onsite Terrestrial EU The terrestrial onsite area includes the non-industrial portions of the Site which are characterized by heavily forested habitats. The onsite terrestrial EU is generally bound by Willis Creek to the north and Georgia Branch Creek to the south, the Cape Fear River to the east and Highway 89 to the west. Terrestrial ecological receptors are expected to use this area for foraging and habitat. 2.4.2.2 Offsite Terrestrial EU The terrestrial offsite area includes the 12 EUs identified in the Human Health SLEA workplan (Geosyntec, 2019c). Receptors in these EUs may be exposed to Table 3+ PFAS TR0795 13 December 2019 that has been aerially deposited and accumulated in or on soil, plants or invertebrates. While the Human Health SLEA has evaluated exposures at each EU, this Ecological SLEA has combined these EUs based on similar habitat qualities and expected receptors. The offsite terrestrial EU extends approximately 6 miles outward from the Site and is characterized by mixed residential and farming land uses, patches of undeveloped forested habitat and creeks, streams and other tributaries of the Cape Fear River. 2.4.2.3 Cape Fear River EU The Cape Fear River or aquatic EU includes the Cape Fear River between Willis Creek to the north and Georgia Branch Creek to the south. This EU includes the in-water portion of the Cape Fear River and banks that would be used by aquatic-dependent birds and mammals while foraging at the river. While the Human Health SLEA included samples downstream of the Site, based on the current understanding of where ecological exposures are expected to be greatest, this Ecological SLEA focused on the Site-adjacent area of the Cape Fear River. 2.4.3 Potentially Complete Ecological Exposure Pathways The ecological CSM (Figure 2-4) reflects the potential exposure of receptors to Table 3+ PFAS, including aquatic life in the Cape Fear River and tributaries, aquatic dependent wildlife foraging in the Cape Fear River and banks, terrestrial plant and invertebrate communities, and herbivorous and invertivore wildlife and carnivorous wildlife. Exposures may potentially occur to Table 3+ PFAS via surface soil, surface water and sediment, along with potential exposures via diet items if Table 3+ PFAS have accumulated in plants, invertebrates and fish. The following receptors and exposure pathways were assumed to be complete for purposes of the Ecological SLEA: •Aquatic life includes benthic and pelagic invertebrates and fish in the Cape Fear River. Pelagic fish, invertebrates and aquatic plants may potentially be directly exposed to Table 3+ PFAS in the water column. Benthic invertebrates may potentially be directly exposed to Table 3+ PFAS in sediments. Exposures to aquatic life were estimated from the surface water and sediment datasets. •Aquatic-life dependent birds and mammals may potentially be exposed to Table 3+ PFAS indirectly via consumption of plants, fish or benthic invertebrates that have accumulated Table 3+ PFAS from water or sediment. Exposures to these receptors will be estimated from concentrations in diet items for each representative receptor. Birds and mammals may also be exposed via the incidental consumption of sediment while foraging for food and surface water as drinking water. TR0795 14 December 2019 •Terrestrial plant and invertebrate communities may potentially be directly exposed to Table 3+ PFAS present in surface soils or via air deposition in the surrounding areas of the Site. Exposures to plant and soil communities were evaluated using the surface soil dataset. •Terrestrial avian and mammalian receptors may potentially be indirectly exposed to Table 3+ PFAS from consumption of terrestrial plants or invertebrates that may have accumulated Table 3+ PFAS. Exposures to these receptors were estimated from concentrations in diet items for each representative receptor. Birds and mammals may also be exposed via the incidental consumption of soil while foraging for food or surface water as drinking water. •Terrestrial avian and mammalian carnivores may potentially be indirectly exposed to Table 3+ PFAS from consumption of small mammals and birds that may have accumulated Table 3+ PFAS from the food web. A tissue sampling dataset sufficient to quantitatively evaluate this pathway was determined to be infeasible for the time available to complete this Ecological SLEA, however considerations such as bioaccumulation potential of Table 3+ PFAS and identification of the Table 3+ PFAS that are responsible for the majority of exposure to herbivores and invertivores may be informative to understand potential exposures to avian and mammalian carnivores. Exposure to these receptors is discussed in the Uncertainties Section (Section 5). TR0795 15 December 2019 3 ECOLOGICAL SLEA METHODOLOGY The Ecological SLEA included multiple field efforts to characterize the magnitude and extent of Table 3+ PFAS in various abiotic and biotic components of the foodweb, the selection of representative receptors for each potentially complete exposure pathway, estimating exposure point concentrations (EPCs), and performing foodweb exposure modeling to calculate exposure to wildlife receptors. The methods used for each component of this Ecological SLEA are described below and detailed further in Appendix A.All analytical results for the Ecological SLEA field investigations are provided in Appendix B. 3.1 Field Investigation Offsite Terrestrial Soil, Vegetation and Insects In July 2019, surface soils from each of the 12 Human Health SLEA EUs were sampled using an Incremental Sampling Methodology (ISM). Thirty (30) aliquots of surface soil were collected from the top 0 to 1 foot of soil from publicly accessible sampling locations within each EU (Figure 3-1). All aliquots were composited for each EU, resulting in 12 discrete samples analyzed for Table 3+ Compounds and Method 537 PFAS3 (Table 3-1). The Offsite terrestrial surface soil dataset was used to quantify exposures to terrestrial plant and soil invertebrate communities and incidental soil ingestion of terrestrial birds and mammals. In addition to the collection of surface soil from each EU, terrestrial plant samples were collected as co-located aliquots of vegetation when present at a soil sampling ISM aliquot location (Figure 3-2). Broadleaf plants with non-waxy leaves, berries or fruit within 1 to 2 feet of the ground surface seeded grasses (fescues, ryegrass, wheatgrass) were targeted for sampling. A representative photo log is provided in Appendix C. Twelve (12) samples of sufficient plant tissue mass were collected and analyzed for Table 3+ Compounds and Method 537 PFAS (Table 3-2). Where sufficient mass was collected, samples were also 3 Samples collected under this effort were also analyzed for Method 537 PFAS and these data are presented along with the Table 3+ PFAS results in Appendix B. Table 3+ PFAS, including HFPO-DA, originate from air emissions and historical process water releases at the Site. Table 3+ PFAS were identified in non-targeted analytical studies conducted by Chemours and the method was developed to quantitate the presence of these PFAS. In most exposure media (terrestrial invertebrates, terrestrial and aquatic vegetation, and surface water) the Table 3+ PFAS were more frequently detected and at concentrations often an order of magnitude higher than Method 537 PFAS. The exception was the sediment and fish samples from the Cape Fear River, where Method 537 PFAS were frequently detected at elevated concentrations compared to the Table 3+ PFAS. Of the PFAS data available, the Ecological SLEA evaluated exposures to Table 3+ PFAS originating from releases at the Site to support developing Corrective Actions for these PFAS. TR0795 16 December 2019 analyzed for percent moisture. The terrestrial plant dataset was used to quantity exposures to terrestrial herbivores both onsite and offsite. In addition to the collection of surface soil from each EU, terrestrial invertebrate samples were collected as co-located aliquots of invertebrates when present at a soil sampling ISM aliquot location (Figure 3-3). Earthworms were selected as the preferred invertebrates for analysis due to high lipid and protein content compared to hard shelled invertebrates and high degree of soil association. Since earthworms were not present in soil during soil sampling activities the field team identified and sampled terrestrial insects when present at a soil sampling aliquot location. Terrestrial invertebrates collected included primarily grasshoppers, crickets, and dragonflies. Invertebrates were composited from all aliquots in an EU; not all EUs resulted in the collection of an invertebrate sample of sufficient sampling mass for analysis (Table 3-2). The collected terrestrial invertebrates along with estimated concentrations in earthworms as discussed below were used to quantity exposures to terrestrial invertivores offsite. Surface Water In July and September 2019, surface water samples were collected from the Pond 1/DERC Pond located on Site, Pond B located in the offsite EU-2 (Figure 3-4), and the Cape Fear River (Figure 3-5). The Pond 1 samples were used to quantify exposure to onsite terrestrial birds and mammals from drinking water intake. The Pond B samples were used to quantify exposure to offsite terrestrial birds and mammals from drinking water intake. There were additional Cape Fear River surface water samples that have been collected from previous scopes of work, however only the most recent data from July 2019 were included in the Cape Fear River surface water datasets to reflect current conditions following the interim measures taken at the Site. Additional details on surface water sampling are included in the Human Health SLEA workplan and in Table 3-3. The Cape Fear River dataset was used to quantify exposures to aquatic-life dependent birds and mammals from drinking water and to quantify direct exposures to aquatic life communities (plants, invertebrates and fish). Onsite Soil and Biota-Soil Accumulation Factor Sampling The invertebrate samples collected from the 12 EUs under the Human Health SLEA program did not represent the targeted species of earthworms (Lumbricus terrestris), which were targeted due to high protein and lipid contents and high association with soil over their lifetime compared to other invertebrates. As an approach to estimate the concentrations in earthworms in the offsite EUs, co-located surface soil and targeted earthworm samples were collected from the forested area and seeps near the Site and used to calculate soil-to-earthworm biota-soil accumulation factor (BSAFs) which are the ratio of the concentration of Table 3+ PFAS in earthworm [microgram per kilogram (µg/kg) TR0795 17 December 2019 wet weight (ww)] to the concentration of the same Table 3+ PFAS in soil [µg/kg dry weight (dw)]. In September 2019, Parsons of NC (Parsons) staff collected soil and earthworm samples from locations in the forested areas adjacent to each of Seeps A through D and near the mouth of Willis Creek (Figure 3-6). Soil sub-samples were collected using a stainless- steel shovel from 0 to 1-foot below ground surface (bgs) and sieved to isolate any earthworms within the soil sample while collecting the soil beneath the sieve. For each subsample where no earthworms were collected, the soil was discarded. If one or more earthworms were collected in a sub-sample, that soil was retained for analysis. This process was repeated at a sample location until sufficient earthworm tissue mass was collected for analysis, in some locations requiring multiple composites. Additional details are provided in Appendix A and Table 3-4. Soil and earthworm samples were analyzed for all Table 3+ SOP compounds, Method 537 PFAS and percent moisture where sufficient sample mass was available. Earthworms were allowed to depurate the ingested soils from their digestive tracts for 24 hours prior to submitting to the laboratory so that the samples represented primary earthworm tissue only rather than ingested soil and tissue. BSAFs were calculated with reporting limits (RLs) used to represent results below detection limits; so if a Table 3+ PFAS was detected in earthworm tissue but not soils, the soil RL was used to represent the concentration in soil, and similarly if a result was detected in soil but not in earthworm tissues. If a Table 3+ PFAS was not detected in either soil or earthworms, no BSAF was calculated. The BSAF were then applied to measured concentrations of Table 3+ PFAS in offsite soil samples to estimate wet weight concentrations in earthworm for the offsite EU. For the onsite terrestrial invertebrate dataset, the empirically measured earthworm data were included in the calculation of EPCs. In addition to collecting co-located soil and earthworm samples, Parson staff also collected 5-point composite soil samples from each of the Seeps A through D areas and near the mouth of Willis Creek (Figure 3-6). Composite samples were selected to provide better spatial coverage from the areas adjacent to seeps (i.e. not within the seep channel) and along the Cape Fear River banks. Bank soil samples analyzed for all Table 3+ SOP compounds and Method 537 PFAS. Additional details are provided in Appendix A and Table 3-4. The bank soil data set was used as the onsite terrestrial surface soil dataset to quantify exposures to terrestrial plant and soil invertebrate communities and incidental soil ingestion of terrestrial birds and mammals foraging onsite. TR0795 18 December 2019 Surface Sediment and Aquatic Vegetation Characterization of Cape Fear River sediments near the Site will be completed under a sampling program under CO paragraph 11.2. However, data were not expected to be collected in time for inclusion in this report. Since sediment may be an important exposure media for aquatic life and aquatic-dependent wildlife, a smaller focused sampling program was undertaken for this Ecological SLEA. In October 2019, Parsons and Geosyntec staff collected 6 sediment samples from just upstream of Willis Creek to the Old Outfall (Figure 3-5). Three-point composite sediment samples were collected using a petite ponar sampler to collect surface sediment (0 to 4 inches) and homogenized prior to delivery to the laboratory. At the same time, field staff collected aquatic emergent and floating vegetation in the vicinity of the sediment samples. Samples included duckweed (floating macrophyte) and rooted emergent vegetation along the banks. All sediment and vegetations samples were analyzed for all Table 3+ SOP compounds and Method 537 PFAS. Additional details are provided in Appendix A, Table 3-5 and Table 3-6. The sediment dataset was used to characterize direct exposure to benthic invertebrates and to characterize incidental sediment ingestion by aquatic-dependent wildlife. The aquatic vegetation dataset was used to characterize exposure to aquatic- dependent herbivores. Benthic Invertebrates Benthic invertebrate sampling was undertaken to characterize exposure to invertivore receptors. Initially in July 2019, crayfish/crawfish samples were targeted by placing baited crawfish traps along the Cape Fear River adjacent to the Site, however sampling was not successful; no crawfish were collected after multiple attempts. During fish sampling in September 2019, a few sediment samples were collected with a petite ponar sampler and sieved to evaluate the effectiveness of collecting benthic invertebrates using this approach but was not highly successful as few invertebrates were typically returned in the grab sample. Based on observations of field staff, it was determined that a targeted collection of a highly common species would best allow the collection of sufficient sample mass in the timeframe required for inclusion in this report. Asian clams (Corbicula fluminea), a common invasive species in the region, were identified as being highly abundant in sandy areas along the banks of the Cape Fear River adjacent to the Site. Additionally, it is likely that wildlife invertivores are consuming the commonly occurring invertebrates; therefore, targeted Asian clams were determined as an appropriate exposure metric and deemed likely to be a successful sampling strategy. In October 2019, Parsons and Geosyntec staff collected three discrete samples of Asian clams from the Cape Fear River (Figure 3-7). Samples were collected by loosening the clams from the sediment bed and collecting using a net; clams were sampled from TR0795 19 December 2019 relatively shallow water near banks. Clam samples were submitted as whole body (in shell) for processing at the laboratory. At the lab, soft body tissues were removed from shells, homogenized and analyzed for Table 3+ SOP and Method 537 PFAS. Additional details are provided in Appendix A and Table 3-6. In addition to the targeted Asian clam sample, mixed benthic invertebrates were collected for a composite sample as they were encountered in the field. Invertebrates other than clams that were collected in nets during Asian clam collections, and invertebrates collected in ponar samples near sediment sampling locations were compiled. One sample of mixed invertebrates, consisting primarily of a leech, dragonfly larvae and other insect larvae was collected and composited. These invertebrates were primarily collected from shallow areas near banks during clam sampling. During the ponar sampling, the primary invertebrate collected were additional Asian clam samples. These samples reflect much deeper surface water depths and were a wider spatial composite than the target clam samples, and so were submitted to the laboratory to better understand spatial and vertical variability in the data. The Asian clam and mixed benthic invertebrate samples comprise the benthic invertebrate dataset and were used to characterize exposure to aquatic-dependent avian and mammal invertivores. Fish Tissue From July through September 2019, two fish sampling events were undertaken by Parsons and Geosyntec staff. The majority of fish sampling was to support the Human Health SLEA and therefore all fish samples were processed at the laboratory for analysis of skin-off fillet tissues only. Catfish (both channel and black) and largemouth bass were targeted for sampling using rod-and-reel fishing under this scope of work from locations in the Cape Fear River both upstream, adjacent and downstream of the Site and nearby fish-bearing ponds (Figure 3-7 and Figure 3-4, respectively). Samples were collected from the Cape Fear River adjacent to the Site and downstream to Bladen Bluffs. The downstream samples are outside of the Ecological Aquatic EU and were not included in EPC calculations. Additional details can be found in the Human Health SLEA work plan (Geosyntec, 2019c). As wildlife piscivores typically consume whole body fish, the use of fillet data may not accurately estimate exposure to this group of receptors since internal organs may accumulate PFAS differently than muscle (fillet) tissue (Conder et al., 2008). To better utilize the Site-adjacent data collected under the Human Health SLEA, the laboratory also weighed and analyzed the non-fillet carcass material (bones, organs, skin, blood) from select samples. From the paired fillet and carcass samples, the whole-body concentrations TR0795 20 December 2019 were estimated as the weighted average of fillet and carcass results. From the estimated whole-body concentrations and measured fillet results, whole-body to fillet ratios were calculated for all detected concentrations of Table 3+ PFAS. The whole-body to fillet ratios were calculated for catfish and largemouth bass separately and applied on a species- specific basis to the remaining measured fillet results to estimate whole-body concentrations for those fish samples. As the use of the whole-body to fillet ratios and the larger size of the fish sampled for the Human Health SLEA adds uncertainty to the exposure estimates, a small whole-body targeted fish sampling effort was also undertaken. Smaller whole-body fish were selected as this is more representative of wildlife fish consumption. In September 2019, nine samples of either single fish or single-species composites were collected from the Cape Fear River adjacent to the Site (Figure 3-7). Fish were collected using electrofishing, targeting fish of less than approximately 6 inches to represent a fish size class than can be consumed whole-body by avian and mammal piscivores. Samples of redbreast sunfish (Lepomis auritus), young-of-year largemouth bass (Micropterus salmoides), American eel (Anguilla rostrate), dusky shiner (Notropis cummingsae) and comely shiner (Notropis amoenus) were collected. Where needed, single species composite samples were collected for sufficient sampling mass. Additional details on fish tissue samples are provided in Table 3-7. Most samples were collected from the Cape Fear River adjacent to the Site, with one whole body sample collected downstream to provide a measure of spatial variability. All fish samples from within the Cape Fear River aquatic EU comprise the fish tissue dataset and were used to characterize exposure to avian and mammal piscivores. As noted above, some fish tissue samples were collected downstream of the Cape Fear River EU for the Human Health SLEA. These samples were not included in the calculation of EPCs but are discussed here qualitatively to evaluate spatial variability. 3.2 Calculation of EPCs An EPC is an estimate of a constituent in a medium within some specified exposure point and are applied to quantify exposures to specific receptors under specific conditions or assumptions. EPCs for each detected Table 3+ PFAS in a given media were calculated for use in the Ecological SLEA. Consistent with SLERA guidance, EPCs were selected to be conservative estimates of exposure. EPCs were calculated for each EU on a media specific basis including: onsite and offsite terrestrial surface soil, Cape Fear River sediment, onsite and offsite surface water, TR0795 21 December 2019 terrestrial 4 and aquatic vegetation, offsite terrestrial invertebrates, onsite and offsite earthworms both as measured and estimated using BSAFs and surface soil EPCs, Asian clams and benthic invertebrates, and for each fish species with Comely and Dusky shiners combined. All primary and field duplicate samples were averaged prior to calculation of EPCs. Where a media specific dataset included greater than eight samples with at least four detected results, EPCs were calculated by selecting the lower of the 95% Upper Confidence Limit (95UCL) on the mean or the maximum detected concentration. In cases where the number of samples was less than eight, the maximum detected concentration was used. 95UCLs were calculated using USEPA’s ProUCL statistical software package (version 5.1; USEPA, 2015). ProUCL outputs are provided in Appendix D. For the estimation of intakes for invertivores and piscivores where multiple species-specific EPC were available (i.e. terrestrial empirical results for insects vs estimated in earthworms; different fish species EPCs) the highest species-specific EPC was selected to represent exposure. Additionally, if a Table 3+ PFAS was detected in some media within an EU but was non-detected above RLs in other media in the same EU, the RLs were used to represent the EPC. These approaches are highly conservative and likely to result in estimates of the highest potential exposures, but a high level of conservatism at this stage is consistent with SLERA approaches. 3.3 Receptor Identification Representative terrestrial and aquatic-life dependent avian and mammalian receptors for the quantitative evaluation of ecological risks at the Site were selected in consideration of the CSM, as presented below. All relevant exposure factors for wildlife receptors are provided in Table 3-8 for all terrestrial wildlife and in Table 3-9 for all aquatic-dependent wildlife. Selected representative terrestrial receptors are described below: Bobwhite Quail The bobwhite quail (Colinus virginianus) is a small quail with striped and speckled black, brown, and white plumage. Bobwhite quails can be found in fields, rangelands and open forests in southeastern North American but have experienced a sharp population decline in the past half-century. They eat mainly seeds and leaves as well as insects during breeding season. For the purposes of this SLEA, the Bobwhite quail was assumed to consume 100% plants. 4 As onsite vegetation was not specifically sampled, the maximum of terrestrial or aquatic vegetation was used to represent the onsite vegetation as a conservative approach. TR0795 22 December 2019 Woodcock The woodcock (Scolopax minor) is a small, plump bird with a brown-mottled plumage, short legs and a long, straight bill. Woodcocks are found in forests and shrubby old fields across eastern North America. Their long bill is used for probing earthworms and other invertebrates (snails, millipedes, spiders, beetles etc.) in the soil. For the purposes of this SLEA, the Woodcock was assumed to consume 100% terrestrial invertebrates. Eastern Cottontail Rabbit The eastern cottontail rabbit (Sylvilagus floridanus) is the most common cottontail that is prolific from Canada to South America and throughout the United States. Cottontails are small mammals with a distinct “cotton ball” tail and have a reddish brown to gray coloring. They can commonly be found in fields, meadows and farms but are adaptable to other habitats. The eastern cottontail consumes grasses and herbs and are known to browse on garden vegetables (peas, lettuce etc.). For the purposes of this SLEA, the Cottontail rabbit was assumed to consume 100% plants. Southern Short-tailed Shrew The southern Short-tailed shrew (Blarina carolinensis) is a small, dark gray to sooty black shrew with short legs and a long, pointed snout. It is found in the southeastern United States in pine forests, meadows and even in wet, swampy areas. The shrews are social animals that live in burrow systems beneath the soil. Their diet consists of a variety of invertebrates including insects, annelids, snails, centipedes and spiders. For the purposes of this SLEA, the Short-tailed shrew was assumed to consume 100% terrestrial invertebrates. Selected representative aquatic-life dependent receptors are described below: Wood Duck The wood duck (Aix sponsa) is an ornate patterned waterfowl with iridescent brown and green patterns on each feather. They have an oblong shaped head, a bright belly and dark underwings and chest. They are a common duck in North America and can be found in wooded swamps, on the edges of streams, in overgrown beaver ponds or freshwater marshes. Wood ducks eat seeds, fruits, and insects, and while their diet can vary greatly, studies indicate plant materials comprise at least 80% of their diet (Cornell Lab of Ornithology, 2019). For the purposes of this SLEA, the wood duck was assumed to consume 100% plants, however as noted below may reflect a mixed diet similar to a Mallard. TR0795 23 December 2019 Mallard Duck The mallard duck (Anas platyrhynchos) is a large duck with a flat bill and a rounded head. They are one of the most common ducks found in wetland habitats in North America. Mallards feed primarily on aquatic insects, earthworms, snails, and vegetation. While they do not dive for their food, they are known to dabble for their food by tipping their beak forward in the water. The mallard duck is expected to be a common bird in the Cape Fear River watershed. Both the mallard duck and Wood duck have similar dietary habits reflecting a mixed diet of plants and invertebrates. For the purposes of this SLEA, the Wood duck was assumed to consume 100% plants and the Mallard duck was assumed to consume 100% invertebrates. Great Blue Heron The great blue heron (Ardea herodias) is the largest North American heron with characteristically long legs, a long, narrow neck, and a large pointed beak. Great blue herons have blue-gray plumage with a black stripe over the eye. They live in freshwater habitats and forage for their food including fish, amphibians, reptiles, small mammals, and insects. For the purposes of this SLEA, the Great Blue heron was assumed to consume 100% fish. Although it does consume some invertebrates, avian invertivores were represented by the Mallard duck. Muskrat The muskrat (Ondatra zibethicus) is a large dark brown aquatic mammal with a flat, scaly tail and large feet that are slightly webbed. They are found in ponds, swamps, marshes, wetlands and other wet environments throughout North America. Muskrats mainly eat green vegetation (~95% of diet) but can also eat small aquatic mammals (frogs, fish, crayfish, etc.). For the purposes of this SLEA, the Muskrat was assumed to consume 100% plants. Mink The mink (Neovison vison) is a long and slender, dark-colored mammal. They prefer forested areas that are close to water and are common in all states except for Arizona. Mink have a varied diet and are opportunistic feeders. They are known to eat fish and other terrestrial vertebrates (small mammals) when available. For the purposes of this SLEA, the Mink was assumed to consume 100% benthic invertebrates. River Otter The river otter (Lontra canadensis) is a semi-aquatic mammal with short legs, long bodies and a thick tail. They are dark brown to black and have a wide, round head and webbed feet. River otters build dens in aquatic habitats including freshwater and coastal areas, TR0795 24 December 2019 rivers, lakes, marshes, swamps and estuaries. The limiting factor for river otters is a permanent food supply of aquatic organisms (amphibians, fish, turtles, crayfish etc.) and occasionally small terrestrial mammals. They can be found throughout Canada and most parts of the United States and are adaptable to various climates (cold, warm, high elevations) but are sensitive to pollution. For the purposes of this SLEA, the river otter was assumed to consume 100% fish. 3.4 Exposure Assessment Exposure assessment is the process of measuring or estimating the intensity, frequency, and duration of ecological exposure to a chemical in the environment. This section describes the mechanisms by which these receptors might potentially come in contact with PFAS in environmental media, and the methods for quantifying the degree of contact between potential representative receptors and Table 3+ PFAS. 3.4.1 Direct Exposures Directly exposed communities include terrestrial plants and invertebrates exposed to Table 3+ PFAS in soil; benthic invertebrates directly exposed to Table 3+ PFAS in sediment; and aquatic life (pelagic plants, invertebrates and fish) directly exposed to Table 3+ PFAS in surface water. The media-specific EPCs for terrestrial onsite and offsite soils, Cape Fear River sediment and Cape Fear River surface water were used to evaluate relative exposures for these receptors. EPCs for each detected PFAS in a given media were calculated for use in the Ecological SLEA as discussed in Section 3.2. For HFPO-DA, the media-specific EPCs were compared to the media-specific TRV discussed in Section 3.5. 3.4.2 Calculation of Receptor Intakes For this Ecological SLEA, Site-specific doses for all Table 3+ PFAS were calculated for all terrestrial and aquatic-dependent wildlife receptors (birds and mammals). Ingested doses are presented in daily dose rates per unit of body weight [milligram per kilogram per day (mg/kg-day)] and referred to as total daily intake (TDI). Terrestrial wildlife was assumed to be exposed to Table 3+ PFAS via incidental ingestion of soil during foraging, consumption of surface water and consumption of food/prey items that have accumulated Table 3+ PFAS. Aquatic wildlife receptors were assumed to be exposed to Table 3+ PFAS via incidental ingestion of sediment, consumption of surface water and consumption of food/prey items that have accumulated Table 3+ PFAS. The estimated TDI for each receptor was calculated using generic dose formulas from the Wildlife Exposure Factors Handbook (EPA, 1993), as well as receptor-specific exposure factors TR0795 25 December 2019 as provided in Table 3-8 and Table 3-9, and represents the sum of intake from diet, soil and surface water: Total Daily Intake �TDI;mgkg−day�= TDI𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑+ TDI𝑠𝑠𝑠𝑠𝑑𝑑𝑠𝑠+TDI𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑑𝑑 𝑤𝑤𝑠𝑠𝑑𝑑𝑑𝑑𝑠𝑠 TDI from diet items, soil and surface water are calculated from the concentrations of Table 3+ PFAS in diet items, soil, and surface water, the proportion of each diet item in the overall diet, the daily ingestion rates of these media, receptor body weights and the area use factor which characterize the frequency that a receptors is expected to forage from potentially impacted areas of the Site. For each, TDI is estimated as: TDI𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑= (∑(𝐹𝐹𝐹𝐹𝐹𝐹𝑤𝑤𝑤𝑤 𝑥𝑥 𝐸𝐸𝐸𝐸𝐸𝐸𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 𝑥𝑥 𝐸𝐸) 𝑥𝑥 𝐴𝐴𝐴𝐴𝐹𝐹𝐵𝐵𝐵𝐵TDI𝑠𝑠𝑠𝑠𝑑𝑑𝑠𝑠= (∑(𝐹𝐹𝐹𝐹𝐹𝐹𝑑𝑑𝑤𝑤 𝑥𝑥 𝐸𝐸𝐸𝐸𝐸𝐸𝑠𝑠𝑠𝑠𝑑𝑑𝑠𝑠 𝑥𝑥 𝐸𝐸) 𝑥𝑥 𝐴𝐴𝐴𝐴𝐹𝐹𝐵𝐵𝐵𝐵TDI𝑠𝑠𝑤𝑤= (∑(𝐷𝐷𝐵𝐵𝐹𝐹 𝑥𝑥 𝐸𝐸𝐸𝐸𝐸𝐸𝑠𝑠𝑤𝑤) 𝑥𝑥 𝐴𝐴𝐴𝐴𝐹𝐹𝐵𝐵𝐵𝐵 TDIdiet = Total daily dietary intake (mg/kg-day) TDIsoil = Total daily soil intake (mg/kg-day) FIRww = Daily food ingestion rate (kg wet weight/day) FIRdw = Daily food ingestion rate (kg dry weight/day) DWI = Daily water ingestion rate (L/day) EPCsoil = Exposure Point Concentration in soil (mg/kg dry weight) EPCdiet = Exposure Point Concentration in diet items (mg/kg ww) EPCsw = Exposure Point Concentration in surface water (mg/L) P = Proportion of diet composed of the individual food source AUF = Area use factor (fraction of time spent foraging at the Site) BW = Body weight (kg) Bioavailability of all Table 3+ PFAS were assumed to be 100%. As concentrations of Table 3+ PFAS in soil and sediments were reported by the laboratory in dry weight, the dry matter ingestion rates based on allometric equations in Nagy et al. (2001) were applied for estimating TDIsoil. Tissue data (fish, plant and invertebrates) were reported by the lab on a ww basis and so the wet or fresh matter ingestion rates based on allometric equations in Nagy et al. (2001) were applied for estimating TDIdiet. Ingestion rates, assumed diet items, body weights and home ranges are provided in Table 3-8 for all terrestrial wildlife receptors and in Table 3-9 for all aquatic-dependent wildlife receptors. TR0795 26 December 2019 3.5 Hazard Assessment for HFPO-DA Typically for a SLERA, a conservative Toxicity Reference Value (TRV) for each receptor would be selected for calculating receptor specific hazard quotients following the estimation of exposures. Outside of HFPO-DA there are no TRVs for Table 3+ PFAS. These compounds are byproducts of the manufacturing process rather than products which are registered substances and consequently there are no available toxicity (hazard) information for these PFAS. Though a limited number of toxicity tests have been completed, the toxicity testing that has been performed on HFPO-DA is sufficient to evaluate the potential hazard to the environment. For the HFPO-DA assessment, the estimated exposures (as direct exposure or estimated TDI from the exposure models) were compared to TRVs to calculate a Hazard Quotient (HQ) as: HQ = Exposure (𝑚𝑚𝑚𝑚𝑘𝑘𝑚𝑚,𝑚𝑚𝑚𝑚𝐿𝐿 𝑠𝑠𝑠𝑠𝑚𝑚𝑚𝑚𝑘𝑘𝑚𝑚−𝑑𝑑𝑑𝑑𝑑𝑑)TRV (𝑚𝑚𝑚𝑚𝑘𝑘𝑚𝑚,𝑚𝑚𝑚𝑚𝐿𝐿𝑠𝑠𝑠𝑠𝑚𝑚𝑚𝑚𝑘𝑘𝑚𝑚−𝑑𝑑𝑑𝑑𝑑𝑑) A critical component of HQ calculation is the selection of a TRV that represents appropriate receptors and endpoints (growth, reproduction or development). The ecotoxicity of HFPO-DA and TRVs selected for HFPO-DA are described briefly below and provided in Table 3-10. Toxicity to Soil Plant and Invertebrate Communities The TRV selected for the evaluation of hazards to soil plant and invertebrate communities is the Probable No Effects Concentration (PNEC) of 0.066 mg/kg dw as reported in ECHA (2019). This PNEC was calculated using an equilibrium partitioning approach where a toxicity value based on exposure in water is converted to a soil or sediment basis. For the soil PNEC reported by ECHA (2019), the PNEC aqua-freshwater was converted using a KOC of 12 L/kg (log KOC of 1.08), and the appropriate equations from the REACH Guidance on Information Requirements and Chemical Safety Assessment: Part B, Hazard Assessment, and a correction factor of 1.13 for conversion to dry weight. As the value was based on aquatic species, there is higher uncertainty related to the applicability of this value to terrestrial invertebrate and plant communities. Toxicity to Sediment Benthic Invertebrate Communities The TRV selected for evaluation of hazards to benthic invertebrate communities is the PNEC of 0.518 mg/kg dw as reported in ECHA (2019). Similar to above, the PNEC value was calculated using the equilibrium partitioning approach with a KOC of 12 L/kg (log KOC of 1.08), the PNEC aqua-freshwater, the appropriate equations from the REACH TR0795 27 December 2019 Guidance on Information Requirements and Chemical Safety Assessment: Part B, Hazard Assessment, p. 45, and a correction factor of 4.6 for conversion to dry weight. As this value was based on aquatic species but not specifically sediment associated benthic invertebrates, there is some uncertainty regarding the application of this value to evaluate hazards to benthic invertebrates. Toxicity to Aquatic Plants The TRV selected for evaluation of hazards to aquatic plants is the no effect concentration (NOEC) for algae reported in ECHA (2019) of 106 milligrams per liter (mg/L). The basis for this NOEC is an acute 72-hour freshwater toxicity test with algae. Both growth rate and cell count were measured over 72 hours of exposure with no adverse effects at 106 mg/L. Toxicity to Aquatic Life (Pelagic Invertebrates and Fish) The aquatic toxicity of HFPO-DA has been the most well studied exposure route. Both acute and chronic toxicity tests on aquatic invertebrates and fish have been performed under the ECHA Chemical Registration process, as summarized in Hoke et al. (2016), and ECHA (2019). Acute to toxicity to aquatic life was evaluated using acute toxicity tests for rainbow trout (Oncorhynchus mykiss), Japanese medaka (Oryzias latipes), rare gudgeon (Gobiocypris rarus), a freshwater invertebrate (Daphnia magna), and a freshwater green alga, (Pseudokirchneriella subcapitata). Chronic toxicity tests include a 21-day reproductive test with Daphnia magna, and a 90-day early life stage test with Rainbow trout. All tests were performed according to Good Laboratory Practices and in conformance with appropriate OECD test guidelines (Hoke et al. 2016). Acute LC50 or EC50 values were all greater than 96 mg/L. The 90-day early life stage test resulted in NOEC of 1.08 mg/L based on statistically decreased hatching time. However, as noted in Hoke et al. (2016), the empirical data indicated that the change in last hatching day in the highest tested exposure group was only a single day less than controls, which is not considered an ecologically significant endpoint. As no other effects were observed in the highest test group, the unbounded NOEC was 8.89 mg/L. ECHA (2019) applied a 10X uncertainty factor to the statistical NOEC of 1.08 mg/L to derive the reported PNEC of 0.108 mg/L (ECHA, 2019). This Ecological SLEA applied the same 10X UF to the ecologically relevant NOEC of 8.89 mg/L to develop a TRV of 0.889 mg/L for the calculation of hazard quotients . In addition, surface water EPC were compared to the more conservative PNEC of 0.108 mg/L as an additional line of evidence. TR0795 28 December 2019 Toxicity to Birds The TRV for avians is 84.5 mg/kg-day and is based on a chronic reproduction test on Northern bobwhite quail (Colinus virginianus) as reported in ECHA (2019). Adult Bobwhite quail were fed HFPO-DA via spiked food in both a range finding and definitive test. In the range finding test, Bobwhite quail were exposed to HFPO-DA via the diet at nominal concentrations of 0, 100, and 1000 mg/kg for 6-weeks. No treatment related effects on reproduction were observed at the 0 and 100 mg/kg exposure doses. Slight but statistically significant reductions in viability of embryos and in numbers of hatchlings and 14-day old survivors were observed in the 1,000 mg/kg exposure group. The ranging finding test NOEC was 100 mg/kg and the test LOEC was 1,000 mg/kg. In the definitive test, Bobwhite quail were exposed to nominal concentrations of 0, 100, 500, and 1,000 mg/kg in feed over 20 weeks. In this test, no adverse effects on growth or reproductive endpoints were observed in any exposure group. Evaluated endpoints included body weight, food consumption, eggs laid, viable embryos, hatching success, 14-day old survivorship and offspring weight; see ECHA (2019) for a complete list of evaluated parameters. No differences in endpoints were observed among the dose levels. The test resulted in an unbounded NOEC of 1,000 mg/kg, equivalent to a no observed adverse effect level (NOAEL) of 84.5 mg/kg-day (ECHA, 2019). The definitive test NOAEL was selected as the TRV over the range finding test NOEC due to the longer exposure duration. Toxicity to Mammals For mammals, the chronic toxicity studies summarized in EPA (2019) and other literature were evaluated to identify studies with appropriate endpoints for evaluation ecological hazards focusing on growth, development and reproductive endpoints. These endpoints are typically included in TRVs as these can be more directly associated with ecologically meaningful adverse effects at the population level. Therefore, many of the reported results in EPA (2019) were not appropriate for use as wildlife TRVs due to sub-organism or subcellular endpoints. Two chronic reproductive and development studies were performed in 2010 by DuPont and are summarized in EPA (2019). From the first study, a NOAEL of 0.5 mg/kg/day was reported based on decreased F1 generation pup weights in mice at the next highest dose (LOAEL, 5 mg/kg/day). In the second study, a NOAEL of 10 mg/kg/day was reported based on early delivery and decreased fetal weights in rats at the next highest dose (LOAEL, 100 mg/kg/day). Consistent with EPA recommendations on wildlife TRVs (USEPA, 2005), the highest NOAEL below the lowest reported LOAEL was selected as the TRV – 0.5 mg/kg/day. TR0795 29 December 2019 4 ECOLOGICAL SLEA RESULTS 4.1 Data Analysis and QA/QC All analytical data were reviewed using the Data Verification Module (DVM) within the LocusTM Environmental Information Management (EIM) system, which is a commercial software program used to manage data. Following the DVM process, manual reviews of the data were 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 EPA Guidance for Labeling Externally Validated Laboratory Analytical Data for Superfund Use (USEPA, 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 QA/QC samples; •MS/MSD recoveries and the relative percent differences (RPDs) between these spikes; •Laboratory control sample/control sample duplicate recoveries and the RPDbetween these spikes; •Surrogate spike recoveries for organic analyses; and •RPD between field duplicate sample pairs. All results of the Ecological SLEA sampling are provided in Appendix B. Results are presented with all validator flags. Some results were rejected following data validation due to very poor matrix spike recoveries. All rejected results were reported as non- detected results and included results for Byproduct 4, Byproduct 5, PFECA-G, FPMOAA, PFO4DA and R-EVE in in various on and offsite media. Laboratory reports and data validation summaries are provided in Appendix E. Under the scope of the Ecological SLEA, samples of soil, surface water sediment, insects, earthworms, and fish tissue were collected. As is typically the case with tissue sampling, some samples consisted of lower tissue mass resulting in some cases where only a single analysis of Table 3+ SOP compounds was performed (i.e. MS/DUP samples that are run per the SOP could not be run). RPDs for SLEA samples for which duplicate analysis were performed were all within 50%, with the exception of one RPD of 57%, indicating that the reproducibility of the sample analysis is very good. Matrix spike recoveries for SLEA samples for which matrix spikes were performed showed 33% of the spike recoveries TR0795 30 December 2019 were outside laboratory control limits, indicating that there may be some effect of the SLEA matrices on the analytical results. 4.2 Empirical Data Trends 4.2.1 Detection Frequencies of Table 3+ PFAS in Media Terrestrial Exposure Units In soil samples collected onsite near seep areas the following Table 3+ PFAS were detected, including: •HFPO-DA, •PFMOAA, •Perfluoro-3,5-dioxahexanoic acid (PFO2HxA), •Perfluoro-3,5,7-trioxaoctanoic acid (PFO3OA), •Perfluoro-3,5,7,9-butaoxadecanoic acid (PFO4DA), •Perfluoro-3,5,7,9,11-pentaoxadodecanoic acid (PFO5DA), •Perfluoro-2-(perfluoromethoxy)propanoic acid (PMPA), •2,3,3,3-Tetrafluoro-2-(pentafluoroethoxy)propanoic acid (PEPA), •Perfluoro-3,6-dioxa-4-methyl-7-octene-1-sulfonic acid (PFESA-BP1), •Perfluoro-2-{[perfluoro-3-(perfluoroethoxy)-2-propanyl]oxy}ethanesulfonic acid (PFESA-BP2), •Byproduct 4, •Sodium 1,1,2,2-Teatrafluoro-2-(1,2,2,2-tetrafluoroethoxy)ethane-1-sulfonate (NVHOS), and, •Hydro-EVE Acid. Meanwhile, Byproduct 5, Byproduct 6, EVE Acid, R-EVE, Perfluoro(2- ethoxyethane)sulfonic acid (PES), Perfluoro-3,6-dioxaheptanoic acid (PFECA B) and (Perfluoro-4-isoproproxybutanoic acid) PFECA-G were not detected in onsite soil samples. Detection frequencies ranged from 9% to 100% and are provided along with summary statistics in Table 4-1. HFPO-DA, PFMOAA and PFO2HxA were the most frequently detected. As discussed in Geosyntec (2019b), Table 3+ PFAS profiles of combined process water and other process waters sources tend to reflect PFMOAA and a TR0795 31 December 2019 mix of other Table 3+ PFAS, where air emissions tend to reflect PMPA, HFPO-DA and PFO2HxA primarily. Onsite soil samples from the seep areas appear to reflect process water sources consistent with the current CSM. The detection frequencies of each Table 3+ PFAS in the evaluated onsite media are provided in Figure 4-1. Data from the onsite seeps were included in this figure to provide information regarding detection profiles but was not considered an exposure media for wildlife. A higher frequency of detections was observed for onsite soil samples compared to offsite soil samples (Figure 4-2). In soil samples collected via ISM from each Human Health SLEA EU, only HFPO-DA and PFO2HxA were detected (Table 4-2). The detection of only HFPO-DA and PFO2HxA in surface soils supports air emissions as the primary source of Table 3+ PFAS to this EU, however this is complicated by the varying sensitivities of Table 3+ SOP methods between Table 3+ PFAS and between solid and liquid media; it is possible additional Table 3+ PFAS are present in soil below RLs for soil but may be detectable in other media (groundwater, plants) within the same EU. Surface water samples collected from both onsite (Pond 1 or DERC pond) and offsite (Pond B) resulted in a very similar set of detected Table 3+ PFAS (Figure 4-1 and Figure 4-2). HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PFO5DA, PMPA, PEPA, PFESA-BP2, Byproduct 4, NVHOS, Hydro-EVE Acid, and R-EVE were detected in onsite pond surface water samples at detection frequencies of 100% (Table 4-3). These same PFAS, with the exceptions of NVHOS and Hydro-EVE Acid were detected in offsite Pond B with detection frequencies ranging from 66% to 100% (Table 4-4). In vegetation samples collected from the offsite areas using an ISM approach, more Table 3+ PFAS were detected than were detected in the soil samples also collected from the EUs (Figure 4-2). HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PMPA, PEPA, Byproduct 4, Byproduct 5, NVHOS, R-EVE, PES, PFECA B were detected at detection frequencies ranging from 8% to 100% (Table 4-5). PMPA was the most frequently detected compound, followed by HFPO-DA and PFO2HxA, which is consistent with the expected profile of Table 3+ PFAS with air emissions as the primary source (Geosyntec, 2019b). Insect samples (primarily grasshoppers and crickets) collected from the offsite EUs resulted in a detection profile more similar to the terrestrial vegetation samples compared to offsite soil samples (Figure 4-2). HFPO-DA, PFMOAA, PMPA, PEPA, PFESA-BP1, Byproduct 4, and R-EVE were detected in offsite insect samples with detection frequencies ranging from 9% to 27% (Table 4-6). PMPA was the most frequently detected compound, followed by HFPO-DA, which is consistent with the expected profile of Table 3+ PFAS with air emissions as the primary source (Geosyntec, 2019b). TR0795 32 December 2019 Onsite earthworm samples collected from near the seep areas of the Site resulted higher detection frequencies for more Table 3+ PFAS than in the offsite insect samples (Table 4-7). These results are consistent with the expectation that offsite invertebrates were primarily exposed via air deposition, whereas the onsite earthworm samples near the onsite groundwater seeps were more likely exposed higher concentrations of PFAS originating from historic process water releases. The detection profile in earthworms showed a high degree of similarity to the detection profile to seep groundwater samples, more so than to surface soil samples, indicating the seep groundwater is potentially the primary exposure media for invertebrates in this area (Figure 4-1). Based on detection frequencies in earthworm samples, the predominant Table 3+ PFAS include HFPO-DA, PFO3OA, PFO5DA. PEPA, PFESA-BP2, Byproduct 4, and R-EVE indicating a process water source (Geosyntec, 2019b). Byproduct 6, EVE Acid, Hydro EVE Acid and PFECA-G were not detected in any offsite media and therefore were not included in the quantification of exposures. Similarly, Byproduct 6, EVE Acid and PFECA-G were not detected in onsite media and were therefore not included in the quantification of exposures for onsite receptors. Aquatic Exposure Unit The detection frequencies of each Table 3+ PFAS in the evaluated aquatic media are provided in Figure 4-3. Only HFPO-DA was detected in one surface sediment sample from the Cape Fear River in the Site-adjacent area evaluated (Table 4-8). No other Table 3+ PFAS were detected. The sampling program included in the Ecological SLEA was a focused sampling event to provide input data to evaluate exposures. A surface sediment sampling program for a larger extent of the Cape Fear River has been developed as per the Sediment Characterization Plan (Geosyntec, 2019d). DEQ provided comments on the plan on November 20, 2019 and at the time of writing Chemours was in the process of responding to DEQ’s comments. This sampling scope of work is expected to provide a more extensive dataset. The results from sediment samples collected immediately upstream, adjacent and downstream of the Site indicate that Table 3+ PFAS are not accumulating in sediment above detectable concentrations. Considering the low log Koc values for the Table 3+ PFAS and the sensitivities of analytical methods for soils/sediment compared to water, there is some uncertainty if Table 3+ PFAS may be present in the sediment porewater at detectable concentrations while concentrations are below RLs in bulk sediment. The detection frequencies of each Table 3+ PFAS in the evaluated aquatic media are provided in Figure 4-3. TR0795 33 December 2019 In the Cape Fear River surface water samples, HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PMPA, Byproduct 4, Byproduct 5, NVHOS, and R-EVE were detected with detection frequencies ranging from 11% to 100% (Table 4-9). A similar detection profile was observed in aquatic plants (Figure 4-3). HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PFO5DA, PMPA, PEPA, Byproduct 4, NVHOS, and R-EVE detected in aquatic vegetation at detection frequencies ranging from 16% to 66% (Table 4-10). Notably, no Table 3+ PFAS were detected in Asian clams or the mixed benthic invertebrate sample. Asian clams do not appear to accumulate Table 3+ PFAS to an appreciable extent. Asian clams were sampled as their high abundance resulted in a likely to be consumed invertebrate and efficient sampling program. Benthic invertebrates more closely associated with sediment porewater than Asian clams were not sampled due to the relative limited availability of these species in the sampling area. Species with a closer porewater association are in general associated with greater bioaccumulation of sediment associated chemicals. In largemouth bass and catfish fillet samples from within the Aquatic EU, PFO4DA and PMPA were detected at detection frequencies ranging from 33% to 50% (Figure 4-3). However, additional Table 3+ PFAS were detected in largemouth bass, bluegill sunfish, catfish and red-breasted sunfish fillet samples from further downstream (CFR-09, MM- 68 and Bladen bluffs) including HFPO-DA, PFMOAA, PFO5DA and R-EVE. Most Table 3+ PFAS detected in fillet samples (PFMOAA, PFO4DA, PFO5DA, PMPA, Byproduct 4 and R-EVE) along with PFESA-BP2 and NVHOS were detected in whole- body fish and fish carcass samples as well (Figure 4-3; Table 4-11). Table 3+ compounds PFESA-BP1, PFESA-BP2, Byproduct 6, EVE Acid, Hydro EVE Acid, PES, PFECA-B and PFECA-G were not detected in any aquatic media and therefore were not included in the quantification of exposures for this EU. 4.2.2 Spatial Patterns of Table 3+ PFAS in Media Terrestrial EUs In offsite surface soil samples, the limited detections of HFPO-DA and PFO2HxA occurred in EU-1, EU-3, and EU-5, which are the EUs closest to the Site and in the predominant wind direction. As discussed above, the detections of HFPO-DA and PFO2HxA support air emissions as the primary source, though typically PMPA is expected to be detected in air emission sourced PFAS; PMPA was not detected here, is more mobile in the subsurface than HFPO-DA and PFO2HxA and so the lack of detection may reflect this higher mobility. TR0795 34 December 2019 Offsite vegetation samples showed a similar pattern, with the most detected Table 3+ PFAS in EU-1. Detections in plants were much more frequent than in soil. Generally higher concentrations of the sum of all Table 3+ PFAS were observed in EU-2 and EU- 11 (Figure 4-4). This was generally expected for EU-2 given proximity to the Site. Notably elevated concentrations of NVHOS and PMPA were observed at EU-11 and of HFPO-DA at EU-12. Given that the available soil and groundwater data in these EUs do not indicate relatively elevated concentrations of HFPO-DA, no clear mechanism for this pattern is evident. In addition to a higher detection frequency for Table 3+ PFAS, the concentrations detected in onsite soils were typically at least an order of magnitude higher. The maximum concentration of HFPO-DA in offsite soils was 2,600 nanogram per kilogram (ng/kg) but was detected up to 29,500 ng/kg in onsite surface soil samples. PFO2HxA was detected as high as 2,300 ng/kg in offsite soils, but as high as 47,000 ng/kg in onsite soils. While other Table 3+ PFAS were not detected above RLs in offsite soil samples, Table 3+ PFAS in onsite soils ranged as high as 150,000 ng/kg for PFMOAA. The onsite surface soil samples were the only surface soil data with the full Table 3+ PFAS data set available and the limited scope did not enable and assessment of spatial trends. However, based on the results of onsite subsurface soil samples (Geosyntec, 2019b), the combined data suggest that concentrations of HFPO-DA may be elevated near historical process water release locations and along the eastern edge of the Site where observed groundwater seeps containing PFAS from historical process water releases. Concentrations in subsurface are typically lower on the southwestern edge of the Site, though surface data are lacking for this area. Aquatic EUs The focus of the aquatic EU area is the Cape Fear River from north of the Site at Willis Creek south to approximately Georgia Branch Creek. The concentrations of total Table3+ PFAS were generally highest in soils and aquatic vegetation from near the onsite seep areas, with lower concentrations in media sampled below the dam (Figure 4-5). In sediment samples collected from this area, limited detections did not enable an assessment of spatial patterns. In aquatic vegetation samples, Total Table 3+ PFAS were highest in the Site adjacent area and decreased in samples below the dam. Concentrations of Table 3+ PFAS in aquatic vegetation were in the same order of magnitude as terrestrial plant samples, with the exceptions of PFMOAA, PFO2HxA, and PEPA which were typically an order of magnitude higher in aquatic samples. In whole-body fish samples collected from the Aquatic EU, no clear spatial patterns were observed which is consistent with the expectation that many fish will forage throughout the Aquatic EU rather than spatially distinct areas. When evaluated along with TR0795 35 December 2019 downstream fillet samples collected at Bladen Bluffs and CFR-09 and upstream at River Mile 68, concentrations of Table 3+ PFAS were generally on the same order of magnitude as samples collected from areas adjacent to the Site, with no clear decrease in concentrations. HFPO-DA was detected in 3 of 6 largemouth bass samples from these downstream locations but was not detected in samples from closer to the Site. Samples of other species from Bladen Bluffs did not result in detectable HFPO-DA. PFO4DA was also detected at an order of magnitude higher in a Bluegill sunfish sample from Bladen Bluffs compared to Site-adjacent samples. 4.2.3 Bioaccumulation Potential of Table 3+ PFAS The bioaccumulation potential of a compound is of particular interest when considering ecological exposures. Compounds that are non-metabolizable and have high accumulation potential result in elevated exposures to upper trophic level organisms, many of which are important species for ecological function. Metabolizable compounds are typically removed by organisms at a rate that prevents this accumulation in the absence of on-going exposures. HFPO-DA is expected to be metabolized and have a low bioaccumulation potential based on results of bioconcentrations tests with fish (DuPont,2009b; Hoke et al., 2016; Goodband, 2019, Pan et al., 2017), and is expected to be metabolizable in mammals based on the lack of detections in human blood serum of exposed populations (Kotlarz et al, 2019; NC State University, 2018). As part of the estimation of TDI in each EU, Site-specific Soil to Terrestrial Invertebrate Bioaccumulation Factors (BSAF) and fillet to whole body ratios for fish were calculated to expand the utility of these datasets, and can provide some indication of bioaccumulation of Table 3+ PFAS in these media. Soil to Terrestrial Invertebrate Bioaccumulation The paired soil and earthworm samples are a useful indicator of terrestrial bioaccumulation potential for Table 3+ compounds. Six samples of paired soil and earthworms were collected from areas of the Site where a high concentration of Table 3+ compounds in soil was anticipated, specifically areas near groundwater seeps along the Cape Fear River. These areas were targeted with the expectation that a higher frequency of detected compounds and higher concentrations would occur, allowing for a better dataset to understand bioaccumulation and evaluation of exposures under reasonable worst-case conditions. TR0795 36 December 2019 The ratio of each detected Table 3+ PFAS in earthworm (ng/kg ww) to soil (ng/kg dw) was calculated for each paired sampled and averaged for a Site-specific BSAF (Table 4- 12). The results indicated the following: •BSAFs for Byproduct 4, Byproduct 5, NVHOS, and R-EVE ranged from 2 kg ww/kg dw to 12 kg ww/kg dw and were all greater than 1, indicating accumulation of these PFAS from soil to earthworm tissues. •BSAFs for HFPO-DA, PFMOAA, PFO2HxA, PFO3OA, PFO4DA, PFO5DA, PMPA, PEPA, PFESA-BP1, PFESA-BP2, and Hydro-EVE Acid were all below 1, indicating negligible bioaccumulation from soil to earthworms. •BSAFs for Byproduct 6, EVE Acid, PES, PFECA B, PFECA-G could not be calculated due to a lack of detections in either media. Whole-body to Fillet Ratios for Fish Flathead, channel and blue catfish along with angler sized largemouth bass were collected in support of the HH-SLEA. These samples were analyzed for fillet only, however six samples were analyzed as both fillet and carcass samples to estimate whole-body to fillet ratios (Table 4-13). The whole-body to fillet ratios (WB:F) were then applied to the fillet EPCs for use in estimating exposure. This step also provided information on the tissue specific partitioning of Table 3+ PFAS. Based on data availability, WB:F ratios were calculated for either largemouth bass or catfish for PFO4DA, PFO5DA, PMPA, PFESA- BP2, Byproduct 4, and R-EVE. Generally, concentrations were higher in carcass samples, resulting in WB:F ratios greater than 1 (1.2 to 4.6). PFO4DA in catfish and PFESA-BP2 in largemouth bass resulted in WB:F ratios less than one, suggesting higher partitioning in fillet muscles. However, ratios were variable between samples of the same species and given the small size of the data set are uncertain. 4.2.4 Summary of Observations from Empirical Data: Based on empirical data collected the following observation were made: •Neither offsite soil nor Cape Fear River sediment resulted in high detection frequencies of any Table 3+ PFAS though given the difference in sensitivities between soil and sediment analytical methods compared to aqueous media analytical methods some uncertainties remain regarding the magnitude of potential exposure to porewater, but this exposure is bounded by the soil and sediment reporting limits. TR0795 37 December 2019 •Accumulation of Table 3+ PFAS in both terrestrial and aquatic plants was observed, but accumulation in invertebrates was limited to terrestrial invertebrates; Table 3+ PFAS were not detected in the sampled aquatic invertebrates though some uncertainties remain regarding the presence of and bioaccumulation in species with different feeding mechanisms. •PFMOAA, PMPA, NVHOS, PFO4DA, PFO5DA, Byproduct 4, and R-EVE were the primary Table 3+ PFAS detected in whole-body fish in the Aquatic EU. Accumulation of these Table 3+ PFAS in fish was observed, but data generally suggest that the other Table 3+ PFAS do not have bioaccumulative potential in fish based on a lack of detections in fish tissue samples. •The higher detection frequencies of Table 3+ PFAS in soil samples near onsite seeps are consistent with the current CSM. The detection profile of Table 3+ PFAS in groundwater and seeps from the onsite area are reflective of process water. The detection profile in soils in the offsite area appear to reflect aerial emissions and aerial deposition processes. 4.3 Quantification of Exposure The data for soil, sediment, surface water, plant, invertebrates and fish tissue were used to estimate TDIs for the potentially exposed receptors described in Section 3.3. EPCs and TDIs were calculated on an EU specific basis as described in Section 3.4. Results are discussed for each EU below. 4.3.1 Exposure Point Concentrations EPCs were calculated for all EU specific exposure media as described in Section 3.2 Summary statistics for each EU and media specific exposure datasets are provided in Tables 4-1 through 4-11. For each Table 3+ PFAS the EPC is selected for that media in its respective Summary Statistics table. EPCs for all media are compared for the primarily detected Table 3+ PFAS in the Figure 4-6 series. As indicated in this figure set, the highest EPCs were variable for different compounds. For many Table 3+ PFAS (HFPO-DA, PFMOAA, PFO2HxA, PMPA, PEPA, and NVHOS) the highest EPCs were observed in plants; for other compounds (PFO3DA, PFO5DA, PEFSA-BP1, PEFSA-BP2, Byproduct4, Hydro-EVE and R-EVE) the EPCs were highest for invertebrates; only one compound resulted in the highest EPCs in fish tissue (PFO4DA). TR0795 38 December 2019 4.3.2 Onsite Terrestrial The onsite terrestrial dataset includes surface soil and earthworm samples collected from the areas of known seeps on Site, and surface water from the onsite Pond 1. No onsite vegetation samples were collected, however the maximum concentration of either the aquatic or offsite terrestrial vegetation samples were applied as the plant EPC. EPCs are summarized for the onsite EU in Table 4-14. The onsite soil EPC was used to evaluate exposures for directly exposed plants and invertebrate communities (Table 4-15). For wildlife receptors in the onsite EU, TDI was calculated for each Table 3+ PFAS for each receptor and are presented in Tables 4-16a through 4-16d. As shown in Figure 4-7, TDI for the ΣTable 3+ PFAS were similar for all receptors, ranging from 0.003 mg/kg-bw day to 0.21 mg/kg-bw day. TDI was largely dependent on overall food ingestion rates rather than by feeding guild. The profile of Table 3+ PFAS did vary considerably between herbivores and invertivores in the onsite area. Herbivores were primarily exposed to NVHOS, PFMOAA, PMPA and PFO2HxA. HFPO-DA represented < 5% of TDI of Table 3+ PFAS for herbivores. However the exposure estimates for NVHOS is primarily driven by vegetation, which is based on measurement of offsite concentrations in plants (as discussed above, as onsite vegetation was not sampled the maximum of offsite and aquatic vegetation was used) and so may not reflect true onsite exposures. The profile of Table 3+ PFAS of TDI for invertivores were dominated by PFMOAA, followed by Byproduct4, Byproduct5 and HFPO-DA. HFPO-DA represented ~10% of TDI of Table 3+ PFAS for invertivores. 4.3.3 Offsite Terrestrial The offsite terrestrial dataset includes surface soil samples, vegetation samples and insect samples collected from the offsite EU area using ISM, and surface water from the offsite Pond B. As the offsite insects collected did not represent the targeted soil-associated invertebrates, the maximum of the offsite insect and an estimated offsite earthworm concentration (calculated using Site-specific BSAFs) were applied as the EPCs. EPCs are summarized for the offsite EU in Table 4-17. The offsite soil EPC was used to evaluate exposures for directly exposed plants and invertebrate communities (Table 4-18). For wildlife receptors in the offsite EU, TDI was calculated for each Table 3+ PFAS for each receptor and are presented in Tables 4-19a through 4-19d. As shown in Figure 4-8, TDI for the ΣTable 3+ PFAS was highest for the Eastern Cottontail rabbit (0.12 mg/kg-bw day), but similar for all other receptors, ranging from 0.03 mg/kg-bw day to 0.06 mg/kg-bw day. In the onsite areas, similar concentrations in most diet items resulted in TDIs that were largely dependent on overall food ingestion rates rather than by feeding guild. Here the combined elevated ingestion rate for TR0795 39 December 2019 Cottontail rabbits and higher concentrations in plants than soils and invertebrates resulted in a higher TDI for this receptor. The profile of Table 3+ PFAS between herbivores and invertivores was similar to the onsite area. Herbivores were exposed to much higher levels of NVHOS in this EU accounting for approximately 70% of TDI. PFMOAA was the next highest exposure in herbivores. In invertivores, PMPA, Byproduct 4, Byproduct 5 and HFPO-DA were the most significant contributors to TDI accounting for approximately 60% of TDI. 4.3.4 Aquatic EU The Aquatic EU dataset includes sediment, surface water, aquatic vegetation, Asian clam/benthic invertebrate and fish tissue samples collected from Cape Fear River. EPCs are summarized for the Aquatic EU in Table 4-20. The aquatic sediment EPC was used to evaluate exposures for directly exposed benthic invertebrate communities and the surface water EPC was used to evaluate exposures for directly exposed aquatic life and plants (Table 4-21). For wildlife receptors in the Aquatic EU, TDI was calculated for each Table 3+ PFAS for each receptor and are presented in Tables 4-22a through 4-22f. As shown in Figure 4-9, TDI for the ΣTable 3+ PFAS were highly variable. Herbivores were estimated to have TDI two orders of magnitude higher than other receptors (0.2 mg/kg-bw day and 0.1 mg/kg-bw day for Muskrat and Wood duck, respectively). The fish consuming receptor – Great Blue heron – had the next highest TDI of 0.01 mg/kg-bw day. The mammalian fish-eating receptor – the River otter - resulted in a lower TDI compared to the Great Blue heron due to its larger home range. As Table 3+ PFAS were not detected above method detection limits in benthic invertebrates, invertivore receptors (Mink and Mallard duck) had very low TDI and a highly uniform profile of Table 3+ PFAS primarily reflecting RLs as EPCs for non-detect results. While the profile of the Table 3+ PFAS in invertivores was uninformative due to low detection frequencies, the profile of Table 3+ PFAS between herbivores and piscivores were different. Herbivores consuming aquatic vegetation were exposed to a much higher level of PFMOAA accounting for approximately 66% of TDI. PMPA and PFO2HxA were the next two most predominant of the Table 3+ PFAS. In piscivores, PFO4DA followed by PFMOAA and Byproduct4 were the most significant contributors to TDI. HFPO-DA contributed < 10% of TDI for all aquatic receptors. 4.3.5 Summary of Observations from Quantification of Exposures Based on the evaluation of the Ecological SLEA dataset and quantifications of TDI for various receptors both on and offsite, the following observations are indicated: TR0795 40 December 2019 •The TDI of ΣTable3+ compounds ranged from 0.002 mg/kg-bw day to 0.2 mg/kg-bw day across all EUs and receptors. Exposures occurring onsite are higher than those occurring offsite or in the Aquatic EU. •Terrestrial herbivores are primarily exposed to NVHOS in the offsite EU, and a combination of NVHOS and PFMOAA in the onsite EU, however the EPC for NVHOS for the onsite EU was represented by offsite data adding uncertainty. •Offsite invertivores are primarily exposed to PMPA, Byproduct4, Byproduct5, and R-EVE. Onsite invertivores are primarily exposed to PFMOAA and Byproduct4. •Aquatic herbivores in the Cape Fear River are primarily exposed PFMOAA followed by Byproduct4, Byproduct5 and PMPA. Invertivores are not highly exposed based on the currently available dataset. Piscivores are primarily exposed to PFO4DA, PFMOAA and Byproduct4. •Key Table 3+ PFAS of interest for ecological exposures based on this evaluation include NVHOS, PFMOAA, PMPA, Byproduct4, and PFO2HxA, which represented the Table 3+ PFAS with the highest exposures in the most- exposed ecological feeding guilds (herbivores) in both terrestrial and aquatic habitats. PFO4DA may be of ecological concern for fish-consuming receptors. 4.4 Hazard Assessment of HFPO-DA The TDI for each Table 3+ PFAS for each receptor was calculated as described above. As toxicological benchmarks are available for only HFPO-DA, a hazard assessment specific to HFPO-DA was included in this Ecological SLEA. As discussed in Section 3.5, to evaluate potential hazards via complete exposure pathways to receptors, TRVs were selected as NOAEL or PNEC values from the literature (Table 3-10). To evaluate hazards to directly exposed receptors (aquatic life, terrestrial plants and invertebrates), the EPC for that EU-specific media was compared to the selected TRV to calculate the HQ. For receptors exposed via dietary consumption, the TDI for HFPO-DA was compared to the TRV to calculate the HQ. Overall, the current exposures of HFPO-DA to wildlife are unlikely to result in adverse effects to wildlife communities either onsite, offsite or in the Cape Fear River based on the results of this evaluation. As shown in Table 4-23, HQs ranged from 0.00000008 to 0.24 indicating that current exposures in these EUs do not pose a hazard to ecological receptors. The highest HQ was observed for onsite terrestrial plants and invertebrates TR0795 41 December 2019 based on the PNEC for soil communities. As noted in Section 3.5, the uncertainty regarding the PNEC is high as it was based on aquatic invertebrate toxicity rather than terrestrial. Although there is high uncertainty on the PNEC for soil, based on observations at the Site, plant and terrestrial invertebrate communities are abundant with no observed signs of potential stress. HQs for wildlife receptors were all below 0.02 indicating that current exposures to HFPO- DA not pose a hazard to wildlife. As discussed in Section 3.5, the range finding study for HFPO-DA in birds (ECHA, 2019) indicated some slight reductions in reproduction at a 100 mg/kg dosing level (dose representing the concentration of HFPO-DA in food), but the definitive study NOEC was at the 1,000 mg/kg dose HQs for birds were all < 0.0002 and so if the range finding study NOEC was applied (i.e. a 10X lower TRV), exposures would not result in HQs > 1. 4.5 Additional Data Evaluations and Lines of Evidence Toxicity reference values for many Table 3+ PFAS are still being developed, particularly with respect to ecological receptors. Therefore, it was necessary to investigate additional lines of evidence to inform development of the CSM and to qualitatively evaluate potential risk to biota to support the exposure quantifications and HFPO-DA hazard assessment. The following additional lines of evidence were included: •Results of Whole Effluent Toxicity (WET) testing conducted by Chemours Fayetteville, and •Additional environmental data regarding Table 3+ PFAS in the Fayetteville region and Cape Fear River Estuary. 4.5.1 WET Testing to Evaluate Risks to Aquatic Life Whole Effluent Toxicity (WET) testing at the Site has shown that effluent does not pose a hazard to aquatic life. WET testing is a tool used to evaluate effluent toxicity utilizing an aquatic toxicity test that employs standardized methods (USEPA, 2000). WET tests are used by regulatory agencies to assess water quality, develop permit limits, and assess permit compliance. This type of testing is particularly useful in determining the combined toxicity of effluent to aquatic biota, without identifying the specific chemicals within the effluent that are likely to be responsible for effects. The overarching goal of WET testing is to ensure that water quality criteria are designed with consideration to protecting aquatic ecosystem health (USEPA, 2000). TR0795 42 December 2019 The USEPA has approved the following testing methods to evaluate the acute and/or chronic toxicity of whole effluents to freshwater, marine, and/or estuarine biota: •Acute toxicity to Freshwater and Marine organisms •Chronic toxicity to Freshwater organisms •Chronic toxicity to Marine/Estuarine organisms Per the USEPA (2000), the study design for WET testing must include a control group and a minimum of five effluent concentrations that are ≥ 0.5 dilution factor of the whole effluent. Acute exposures are evaluated for 24, 48, and 96 hours. Chronic toxicity to freshwater organisms is evaluated for four to eight days, while chronic toxicity to marine and estuarine organisms is evaluated for one hour to nine days. Although there are inherent differences in species sensitivities, reproductive toxicity is widely accepted as a sensitive endpoint in toxicity testing, as well as an important indicator of potential population level effects. The Chemours Fayetteville manufacturing facility conducts WET testing in accordance with their National Pollutant Discharge Elimination System (NPDES) permit requirements. Thirteen chronic studies were conducted between February 2016 and February 2019, in which Ceriodaphnia dubia were exposed to 3.3% effluent from the Fayetteville manufacturing facility. Mortality and reproduction of C. dubia were recorded daily for the duration of the test. As seen in Table 4-24, no statistically significant adverse effects on either of the aforementioned endpoints were observed during any of the tests. For context, a 3.3% dilution of effluent containing approximately 40,000-80,000 ng/L of HFPO-DA (which is representative of concentrations in effluent over the time frame of WET tests [Geosyntec, 2019e]) corresponds to an exposure concentration of 1,320 to 2,640 ng/L. Concentrations of HFPO-DA were below this exposure concentration in all SLEA surface water samples from the CFR supporting the conclusion of this Ecological SLEA that there are no potential hazards to aquatic life from current concentrations of HFPO-DA in the CFR. 4.5.2 Additional Regional Environmental Data Certain Table 3+ PFAS were detected in abiotic and biota media in the Cape Fear River and the terrestrial area surrounding the facility. Other efforts by research facilities, including state and Federal agencies, have developed additional datasets regarding the presence of Table 3+ PFAS in the environment. Major findings from publicly available studies are briefly summarized below; many of the studies discussed below are currently in progress and have only reported preliminary findings thus far. TR0795 43 December 2019 Robuck et al. (2019) measured the concentrations of 17 PFAS, including four Table 3+ PFAS, in Atlantic seabirds, as a proxy for homeothermic vertebrates. Chick and juvenile seabirds were sourced from coastal habitats including the CFR Estuary, Massachusetts Bay, and Narragansett Bay. Tissues analyzed included brain, heart, kidney, liver, lungs, muscles, and spleen. Other biological samples analyzed included blood, fat, preen, and feces. The studied analyzed samples for four Table 3+ PFAS (HFPO-DA, PFO4DA, PFO5DA and PFESA-BP2) and non-Table 3+ PFAS (PFOS and other PFSAs, PFCAs, perfluorooctane sulfonaminde). While raw data has been made available for review, based on the presentation of data in Robuck et al. (2019) HFPO-DA was not detected in significant quantities; PFESA-BP2, PFO5DA, and PFO4DA were detected in all CFR Estuary seabirds tissue samples. The relative contributions of these Table 3+ PFAS to total PFAS was highly variable between samples, particularly for PFESA-BP2; however, the study concluded that PFOS is the predominantly accumulated PFAS in all habitats. The data from this Ecological SLEA indicate that fish are not experiencing high rates of HFPO-DA bioaccumulation, though detectable concentrations were observed in some samples. One composite sample of seven Red-ear sunfish caught the Cape Fear River near the Site also had detectable levels of HFPO-DA, though none of the other fish samples collected during that sampling event had measurable levels of HFPO-DA (NCDEQ, 2018). Guillette et al. (2019) also reported detectable concentrations of HFPO- DA and PFESA-BP2 in the serum of Striped bass (Morone saxatilis) and American alligators (Alligator mississippiensis) in the Cape Fear River. However, PFOS was overwhelmingly the largest contributor of the total PFAS body burden in both species (Guillette et al., 2019). Lastly, a human biomonitoring study conducted near the Fayetteville production facility did not find HFPO-DA in blood serum, despite documented community-wide exposure to HFPO-DA via impacted drinking water (Kotlarz et al., 2019). However, other Table 3+ PFAS were detected at a high frequency, including PFESA-BP2, PFO4DA, PFO5DA, and Hydro-Eve. This supports the conclusion that HFPO-DA does not appear to be strongly bioaccumulative or have a long half-life in humans, and that other Table 3+ PFAS may be more frequently detected in upper trophic levels. TR0795 44 December 2019 5 UNCERTAINTIES There are a number of uncertainties related to all SLEAs/SLERAs, based on the use of assumed parameters for ecological modeling, spatial variation of chemicals in media, and organism habitat use patterns, among other uncertainties. While these uncertainties are relevant, the assumptions used in the Ecological SLEA aimed to provide additional conservatism where there was significant uncertainty. For example, exposure parameters were selected to provide reasonable maximum exposure estimates by selecting maximum reported consumption rates, minimum body weight estimates, small home range estimates, and by selecting EPCs based on maximum EPCs in varying diet items (i.e. the highest fish species EPC was selected to represent all fish). The remainder of this section focuses more on project specific uncertainties, such as analytical or field sampling related uncertainties, uncertainties in the analyses and uncertainties in the CSM. Analytical Uncertainties: For Table 3+ analyses the laboratory runs both a primary and laboratory replicate sample and reports the average of the two runs. In some fish tissue and invertebrate samples too small a mass of tissue was available to run both. As noted above in Section 4.1, this does not add additional uncertainty to the analytical results, and the results from the primary are considered usable. Many Table 3+ PFAS were not detected in all media however EPCs are needed for all Table 3+ PFAS to estimate TDI. If a Table 3+ PFAS was not detected in any exposure media in an EU, it was not included in the calculation of exposures. However, if a Table 3+ PFAS was detected in some media of an EU, it was carried forward in the quantification of exposures using the RL as the EPC for media where that compound was not detected. The use of the RL as EPCs will lead to overestimates of exposures. In some instances with a high frequency of non-detect results (e.g. benthic invertebrates, offsite vegetation) substituting zeros for the RLs for non-detect results reduces TDI estimates for these receptors by up to 90%. Uncertainties in the Ecological SLEA Analysis: This analysis did not assess hazards to exposed receptors for Table 3+ PFAS outside of HFPO-DA due to the lack of Table 3+ PFAS specific TRVs. Under Paragraph 14 of the CO, Chemours is evaluating toxicity of PFMOAA, PMPA, PFO2HxA, PEPA, and PFESA‐BP2 to mammalian and aquatic life receptors. These tests include mammalian repeated dose and immunotoxicity studies and aquatic toxicity testing. These results will enable an evaluation hazard for these Table 3+ PFAS. The potential for toxicity of individual Table 3+ PFAS to be influenced by the composition of Table 3+ PFAS mixtures is considered an uncertainty, but this is an uncertainty that occurs with the TR0795 45 December 2019 majority of multichemical hazard assessments and in particular hazard assessments related to any PFAS. The southern hognose snake is a listed species at risk that may potentially be found in the Site. This species is primarily a carnivore and likely has similar exposure to a carnivorous or invertivorous mammal or bird so it is unlikely that an evaluation would indicate potential hazard given the low HQs for HFPO-DA noted herein, but this is considered an uncertainty as no reptiles were evaluated in the Ecological SLEA. Toxicity data on reptiles for any PFAS is scarce (McCarthy et al., 2019; Conder et al., 2019). Larger ranging carnivores that consume small birds and mammals were not included in this evaluation as the collection of small bird and mammal tissue samples to understand exposure to these receptors is a significant undertaking and was not feasible in the SLEA development timeframe. Typically, large ranging carnivores have low exposures due to their large home ranges relative to impacted areas of sites. However, given the large area of detectable Table 3+ PFAS in offsite groundwater and vegetation samples, exposure to these receptors could be significant for Table 3+ PFAS that are not metabolized by small birds and mammals. Based on the available supporting lines of evidence, Table 3+ PFAS to which carnivores may be exposed are primarily PFESA-BP2, PFO4DA, PFO5DA. Vegetation samples were collected from the offsite area to represent terrestrial exposures and from the Cape Fear River to represent aquatic exposures. However, this SLEA did not include the collection of plant samples from the onsite area. Considering elevated concentrations in soil and earthworms near the onsite seeps, this is considered an uncertainty that may underestimate exposure to onsite herbivores. Asian clam samples were collected as they were highly abundant in the aquatic EU and sediment grab samples did not indicate sufficient mass of invertebrate tissues of other species could be collected for analysis in the available time frame. Since Asian clams are abundant, it is likely they are being consumed by wildlife, however they may not represent the highest exposure for benthic invertivores as clams derive their exposure from the overlying water in addition to sediment and porewater. Benthic invertebrates with burrowing or tube-forming feeding habits may have higher exposures due to a closer association with sediment porewater. Uncertainties in the CSM: The higher detection frequency of Table 3+ PFAS in vegetation and insects from the offsite EU and the high detection frequencies of PMPA and HFPO-DA, which are markers for air emission (Geosyntec, 2019b, c) supports that aerial emissions were the migration pathway to the offsite area. It is unclear if the presence of Table 3+ PFAS in plants and insects resulted from both aerial deposition on to the organism directly or from TR0795 46 December 2019 the aerial deposition to soil and subsequent uptake from soil pore water into plants, and consumption of those plants by insects. Understanding the relative contribution of each pathway is complicated by the low frequency of detection in offsite soils. The detection limits in soil are not as sensitive as water (by 2-3 orders of magnitude), and potentially less sensitive than wet weight tissue analysis, therefore the higher detection frequencies in these media may be an artifact of RLs. Alternatively, due to the low log Koc of most Table 3+ PFAS, compounds in soil may rapidly partition to groundwater resulting in non- detects for soil samples but may remain on the tissues of plants and insects resulting in higher detection frequencies. Studies from a PFAS manufacturing facility in the Netherlands with similar release mechanisms provides some indication that these two pathways are both important contributors. Concentrations of HFPO-DA in plant samples from offsite areas were reduced by about half after washing (Mengelers et al., 2018). These results may also suggest that exposure to Table 3+ PFAS may be reduced by washing vegetation; based on this, natural weathering/raining may reduce exposure to ecological herbivores as well, though this has not been studied The similar profiles between plants and insects indicates that air emissions is the primary source regardless of specific uptake pathways into organisms, though no information regarding the timing of deposition either onto organism tissues or in soil porewater for subsequent uptake into organisms is available and may have occurred prior to emission reduction controls put in place by Chemours. The sediment samples collected from the Cape Fear River were widely non-detect for Table 3+ PFAS indicating bulk sediment is not a sink or potential long-term source of Table 3+ PFAS. However, given the noted analytical sensitivities between soil and aqueous matrices and the lower organic carbon partitioning of Table 3+ PFAS there is uncertainty in the potential for Table 3+ PFAS to be present in sediment porewater at detectable concentrations while at concentrations lower than the reporting limit for Table 3+ PFAS in sediment. This could result in exposures to benthic invertebrates that may not be accounted for by the bulk sediment analyses. PFESA-BP2 has been detected by other studies in human blood serum and alligator blood serum (Kotlarz et al, 2019; Guillette et al. 2019; Robuck et al. 2019). However, in this evaluation PFESA-BP2 was not detected in plants from offsite and aquatic areas or in Cape Fear River surface water (but was detected in onsite and offsite Pond water) and was not detected in fish tissue samples. BSAF for earthworm were moderate but complicated by non-detect results in soil and therefore possibly underestimated. The high frequency of detection (FOD) in blood with present information appears to be inconsistent with the low FOD in environment. TR0795 47 December 2019 6 SUMMARY This Ecological SLEA evaluated the presence of Table 3+ PFAS in multiple abiotic and biotic media in the terrestrial areas on and surrounding the Site and in the adjacent Cape Fear River. Ecological hazard and exposure assessments for all PFAS, especially for more recently studied PFAS such as the Table 3+ PFAS, are in their infancy, and a number of uncertainties remain. Overall this Ecological SLEA aimed to evaluate the extent and magnitude of exposures with a reasonable degree of confidence, but conclusions resulting from the data, analyses and interpretation described herein are presented in the context of the uncertainties described above. Up to 17 individual Table 3+ PFAS were detected in samples of onsite soils, invertebrates, terrestrial and aquatic vegetation and fish. Very few (less than two) Table 3+ PFAS were detected in sediment, benthic invertebrates and offsite soils. Concentrations were generally highest in the onsite area relative to the Cape Fear River and offsite terrestrial areas, and predominant exposures are related to consumption of terrestrial and aquatic plants by herbivorous wildlife like rabbits and muskrats. NVHOS, PFMOAA, PMPA, Byproduct4, and PFO2HxA represent the highest exposures to these receptors, and mammalian toxicity evaluation of PFMOAA, PMPA, and PFO2HxA will be very helpful in evaluating the potential hazards of these exposures. Sediment sampled in Cape Fear River and soil sampled in offsite area were primarily non-detect for Table 3+ PFAS, though due to difference between soil and sediment analytical method sensitivities compared to aqueous samples Table 3+ PFAS may be present in these samples where aqueous phases are present (groundwater, porewater). No adverse hazards were identified to ecological receptors from current exposures to HFPO-DA onsite or offsite. The primary exposures are related to the onsite seep areas and consumption of plants in the offsite area. Under the CO, Chemours is implementing significant source control of air emissions and discharges to the Cape Fear River which will significantly reduce exposures to ecological receptors.

All sampling methods, locations, and relevant safety hazards were reviewed and discussed with team members and Chemours representatives. 1.1.1 Decontamination Methods Sample containers were provided by TestAmerica (Sacramento, California). Containers were new and were used only once for each sample. Disposable equipment (i.e. gloves) was not reused and therefore, did not require decontamination. All non-disposable sampling equipment was decontaminated immediately before sample collection using a de-ionized water rinse, scrub with de- ionized water containing non-phosphate detergent (i.e. Alconox®), and a final rinse with de-ionized water. 1.1.2 Sample Shipping, Chain of Custody, and Holding Times Samples were collected, labeled, containerized, and placed into a heavy plastic bag inside an insulated sample cooler with ice. Prior to shipment of the samples to the laboratory, a chain of custody (COC) form was completed by the field sampling team. Sample locations, identifications numbers, descriptions, number of samples collected, and specific laboratory analyses to be performed were recorded on the COC. The COC was signed by the field personnel relinquishing the samples to the courier and was signed by the laboratory upon receiving the cooler. 2 TERRESTRIAL PLANT SAMPLE COLLECTION: Objective: to collect 60 grams (wet) of forage plant material that represents plant material consumed by herbivores. One composite sample per EU. 2.1 Methodology: •At each ISM increment location, look for the following for sampling: o Preferred: Broadleaf plants, within 1 to 2 ft of the ground. Target collecting leaves (berries/fruit if present) and seeded grasses (fescues, ryegrass, wheatgrass) o Secondary: any grasses, weeds with non-waxy leaves •Photograph selected plant(s). •Collect ~ 2 grams of plant material targeting leaves, seeds or berries, not woody stems. •Wipe any loose dirt off the plant with a dry paper towel, but do not wash. •Place in a HDPE sampling container; continue adding to sample at next soil aliquot location. 2.2 Laboratory Analysis Notes: •Minimum mass: 60 grams (estimated pending info from lab; may be revised) •Sampling jar: HDPE •Analyte list: Same PFAS analyte list as soil samples; % moisture 2.3 Examples of appropriate plants: Ferns Wildflowers (Trumpetweed, wood anemone, green and gold) Seeded grasses: 2.4 Avoid waxy cuticles on plants: 3 TERRESTRIAL SOIL INVERTEBRATE SAMPLE COLLECTION 3.1 Objective: •Collect 30 grams (wet) of invertebrate tissue that represents organisms consumed by invertivores. One composite sample per EU. 3.2 Methodology: •At each ISM aliquot, collect additional 0 to 6-inch soil samples and sieve (use the largest sieve size that allows soil to pass through easily) •Collect invertebrates found any of the grabs and place in a HDPE jar: o Sieve enough additional soil to capture 1-2 earthworm (preferred) o Sieve enough additional soil to collect 2-3 grams of non-earth worm invertebrates (if earthworms are not collected) o Collect any invertebrates easily caught above soil (grasshoppers, crickets/katydids,caterpillars) o Feel free to use best professional judgement - if after a couple sieves the area seems very low in invertebrates, move on. If you hit a spot with an abundance of earthworms, collect additional mass from that location. In an ideal world we would have earthworms from all 30 aliquots in an EU but collecting enough sample mass is the critical item. •Continue adding invertebrates to the sampling jar during each aliquot in an EU •At the completion of the EU, evaluate tissue mass for earthworms alone: o If > 30 grams, then composite only earthworm tissues in HDPE jar for analysis o If < 30 grams, add in additional invertebrates to reach mass with preferences for larger invertebrates •Photograph and document final composite sample species make up •Allow sample organisms to depurate (i.e. poop) any consumed soil (primarily by earthworms) by leaving in jar on filter paper for 24 hours. •Remove invertebrates to a clean HDPE jar prior to placing on ice for shipment to the laboratory. 3.3 Laboratory Analysis Notes: •Minimum mass: 30 grams •Sampling jar: HDPE •Analyte list: Same PFAS analyte list as soil samples; % moisture 3.4 Carcass sampling for whole body estimates: 3.4.1 Background: Whole body concentrations of chemicals are preferred for ecological exposures. To best leverage the SLEA fillet sampling, we will be calculating fillet to whole body ratios based on weighted average whole- body concentrations for up to 3 samples of catfish and 3 samples of bass. Every attempt should be made to composite based on specific species or families (i.e., catfish should not be composited with bass). 3.4.2 Methods: •3 samples will be analyzed for PFAS in carcass along with the fillet sample (preference for different locations) o Preferable on single fish samples over composites o Prefer 3 individual or composite samples made up of the same species (or family) for each of bass and catfish •For each sample: o Measure whole body fish weight and standard length of all fish samples o Place all fish for a single composite sample in the same HDPE bag o Samples that will be analyzed for skin-off fillet only, will be labeled on the outside of theHDPE bag with the sample ID (see Work Plan Table 2). o For the samples that will also be analyzed for carcass tissues, label with both the sample ID, and the sample-ID with “-Carcass”. o The laboratory has been provided instructions on sample processing for skin-off fillet and carcass. o In a clean space, away from potential sources (i.e, mechanical equipment/exhaust/etc.) and using clean equipment/materials, remove fillets and weight all fillet meat (free to subsample fillet for lab following weighing); record weight in field notes or summary table (see last page here). o Weight all remaining fish tissue (carcass – bones, organs, any remaining fluids) and place in sampling container for lab (same type of containers for fillet samples are fine). o Clean equipment/materials used for filleting between each fish processed to ensure that there is no cross contamination between samples. o Place individual or composite samples in appropriate (PFAS-free) containers (HDPE bags) o Send samples (fillet and carcass) to the lab for analysis o Carcass sample IDs: please use the same Fillet ID with a “-Carcass” and run for the same list of analytes •If compositing multiple fish, weight each fish using these steps individually prior to composting the fillets and carcasses together. . 3.4.3 Laboratory notes: •Minimum tissue mass: 40 g (30 g for PFAS, 10g for % moisture; ok if short on mass for % moisture) •Sampling container: HDPE bags •Analysis: Method 537/Table 3+ PFAS, % moisture (if sufficient mass) 3.5 Collection and analysis of up to 5 small, benthic fish: 3.5.1 Background: The SLEA captures angler focused species rather than wildlife focused species. To better understand exposures to wildlife, we would like to collect up to 5 samples of smaller benthic fish that are more commonly consumed by wildlife. The goal is to capture exposure to fish- eating birds and mammals which are primarily opportunistic feeders, therefore is a highly abundant species is observed during sampling these are likely highly consumed by wildlife. 3.5.2 Methods: •Field team preference on sampling methods •Preference is to retain fish without major injuries (so as not to lose fluids) •Prior to measurement, euthanize fish quickly without loss of fluid from body cavity •Measure and weigh all individual fish samples prior to processing •Whole body fish should be collected and provided to the lab without further processing •Composite same species, genus, or family of fish (assuming the same feeding strategy) as needed for tissue mass; it would be best to target an abundant species/genus/family with the same feeding strategy (i.e., either primarily benthic feeding or primarily water column feeding and fish of the same size, generally). 3.5.3 Target species: •Sucker species: white sucker, spotted sucker, lake or creek chubsuckers •Shad species: gizzard shad, American shad and threadfin shad •Sunfish species: Bluegill sunfish, spotted sunfish •Minnow species: fathead minnows, shiners Note: List is provided as examples; Field staff have our support in selecting other appropriate smaller (< 12 inches) benthic fish based on species observed during sampling. 3.5.4 Laboratory notes: •Minimum tissue mass: 40 g (30 g for PFAS, 10g for % moisture; ok if short on mass for % moisture) •Sampling container: HDPE bags •Analysis: Method 537/Table 3+ PFAS, % moisture (if sufficient mass) •Please indicate on COC that these are to be processed as WHOLE BODY samples and not skin- off fillet samples. •Recommend Sample IDs CFR-06 (or 07 depending on location)-FISH-WHOLE-1 to CFR-07- FISH- WHOLE-05 3.5.5 Contingency Plan: If low success in capturing additional small whole-body fish for analysis, the need for remobilization and additional sampling in later August will be evaluated based on the completed fish sampling to date. 3.6 Crawfish Trapping and Analysis: 3.6.1 Background: Consumption of benthic invertebrates by wildlife is a complete exposure pathway, and crawfish have been identified as a relatively easy benthic invertebrate that is consumed by wildlife (river otters, minks). 3.6.2 Methods: •Crawfish traps will be deployed at the 4 Cape Fear River EUs •3 baited crawfish traps will be deployed at each EU at different locations for three discrete samples •Check traps at the end of sampling day and collect crawfish. o If insufficient mass (< 40 g) collect crawfish and freeze, leave traps in place to collect additional mass o If sufficient mass, collect and submit to laboratory as whole-body organism for analysis •Measure individual crawfish weights and lengths prior to submitting to the lab. 3.6.3 Laboratory notes: •Minimum tissue mass: 40 g (30 g for PFAS, 10g for % moisture; ok if short on mass for % moisture) •Sampling container: HDPE jars or bags •Analysis: Method 537/Table 3+ PFAS, % moisture (if sufficient mass) 3.6.4 Contingency Plan: If low sampling success, benthic grab sampling for invertebrates may be added to the Sediment Characterization efforts. Site personal have indicated areas near Site are generally softer sediment with relatively high invertebrate density. If crawfish trapping is unsuccessful prior to sediment characterization mobilization, additional sampling notes for benthic grab sampling will be provided. Please contact either Wendy or Jennifer with any questions or concerns during fish, crawfish, plant or soil invertebrate sampling. 4 COLLECTION OF CO-LOCATED SOIL AND EARTHWORMS 4.1 Standard Operating Procedure The Fayetteville soil and earthworm collection effort will target areas of seeps along the Cape Fear River on the Site. These areas are expected to have a high abundance of earthworms based on anecdotal site observations and are expected to represent areas of highest exposure for ecological receptors. The following procedure will be employed to collect collocated soil and earthworm samples at each Seep sampling location (Figure 1). There are five total sampling locations planned for co- located soil and earthworms, however these locations are also being sampled separately for bank soils (see Bank Soil SOP), therefore two soil samples (one for co-located soil/earthworms, one for spatial composites of surface soil) are collected at each seep. •Identify an area approximately 2’ x 2’ that is relatively clear of heavy brush and debris. Sample locations should target the areas near the seep channel and riverbank edge; an example area is shown in Figure 2. •Clear away vegetation and leaf debris as needed to expose surface soil; photograph sample plot and surrounding areas, mark with GPS/record coordinates •Set up a ¼ inch sieve with new or decontaminated HDPE or stainless-steel bin/catcher underneath sieve. •Take a single shovel of surface soil and visually inspect for earthworms. o If earthworms are present, place soil in the sieve and catcher. Sieve soil to expose earthworm. o If no earthworms are visually identified, discard shovel of soil. •Continue collecting, visually evaluating and ,compositing soil samples, targeting 30g of earthworms (5 to 6 big worms); a minimum of 10 grams of tissue is needed for a viable sample but the lab requests 30g where possible. •Once a sufficient mass of worms has been collected in the sieve: o Photograph and then remove the sieve from the catcher/bin o Homogenize soil in bin by mixing with a decontaminated stainless-steel spoon and collect 2x 16-oz jars of homogenized soil for analysis o After soil is collected into sample jars, prepare earthworms. Using lab provided PFAS free water, rinse the earthworms on screen until they are free of soil. Using stainless steel tweezers (or similar), place worms in a glass sampling jar lined with filter paper and a small volume (2-3 drops) of DI water for moisture. Photograph contents of jar. Store jar at ambient temperatures away from sunlight overnight to allow earthworms to depurate. o The next morning, remove earthworms from original container into a clean glass sampling container and place in freezer (if possible) or in a cooler with ice until delivery to the laboratory. •5 soil and 5 earthworm tissue samples will be submitted to the laboratory for analysis of Table 3+ SOP, Method 537-mod. Soil samples will also be analyzed for total organic carbon and tissue samples will also be analyzed for percent moisture. •Sample ID: LOCATION# - MEDIA – DATE as MMDDYY Example: SEEP1-SOIL-091219 or SEEP1-WORM-091319 Figure 1: Seep sample locations for composite soil and co-located soil and earthworm sampling. Note, locations of seeps are approximate. Figure 2: Example areas near seeps to target for co-located earthworm and soil sampling. 5 COMPOSITE SOIL SAMPLING ALONG RIVERBANK 5.1 Standard Operating Procedure The Fayetteville bank soil collection effort will target areas of seeps along the Cape Fear River on the Site. The following procedure will be employed to collect composite soil samples at eight locations (Figures 1 and 2). •At each sampling location, a single composite sample of 6 sub-samples will be collected. While the specific locations of subsamples will vary, similar spatial coverage will be targeted. o For samples collected at each seep location (Figure 1), the 6 sub-samples will be distributed as follows: 3 subsamples will be collected from each side of the seep (Figure 3). Subsamples will be collected outside of the seep channel, targeting 2 ft from the seep channel edge, and spaced 2 ft apart along the seep channel. Samples will be collected as close to the River as safely feasible. o For samples collected at near the Lock and Dam (Figure 2), the 6 sub-samples will be distributed as follows: 6 subsamples oriented parallel to the riverbank (Figure 4). Subsamples will be collected approximately 2 feet from the river and will be spaced approximately 2 feet apart. •Identify an area along the outlet of each sampling location that allows the collection of composite samples according to Figures 3 and 4. Mark out the 6 subsample locations with flags or other markers and photograph from multiple angles, record GPS of each subsample. •For each sample: o At each subsample location, collect a soil sample from 0 to 1 ft using a decontaminated stainless-steel shovel. o Approximately the same sample volume should be collected from each subsample location. o Place subsampled soil in a large decontaminated stainless steel or HDPE bin for compositing. o Composite and homogenize the six subsamples. o Photograph the sample after mixing. o From the soil composite, fill two 16 oz jars for laboratory analysis. •8 composite bank soil samples will be collected for analysis of Table 3+, Method 537 and Total organic carbon. •Sample ID: LOCATION# - MEDIA – DATE as MMDDYY-COMP Example: SEEP1-SOIL-091219-COMP or CFR07a-SOIL-091419- COMP Figure 1: Composite Soil Sample Locations at Seeps.

Rationale: Asian clams have been identified as highly abundant in areas of sandy/gravel banks along this stretch of the Cape Fear River (CFR). Highly abundant organisms provide food sources for wildlife and efficient sample collection when high tissue mass is needed. Sample Locations: pre-determined sampling locations are not included in the SOP. Sampling Methods: https://www.epa.gov/sites/production/files/2014-03/documents/3M6.PDF •Based on previous site surveys and recognizance, the approximate area of sandy/gravel banks have been approximated. Staff will mobilize to the general areas, and using a GoPro observe the bottom to identify the presence of clam beds. •Whole body homogenize (rationale: small, thin shelled, likely consumed whole by organisms; conserve internal juices/water from clams; uncertainty – some organisms do open shellfish and eat only soft tissues, and this may underestimate exposure for that scenario) 7 COLLECTION AND ANALYSIS OF 5 SAMPLES OF AQUATIC VEGETATION. 7.1 Sample Locations: Aquatic vegetation samples will be collected from within and along the banks of the CFR. Samples will be collected from along the western bank of the CFR, in the area of each Sediment sample location (SED1 through SED5; Figure 1. Note SED6 not included for veg. 7.2 Sampling Methods: •Any live aquatic vegetation is considered acceptable for sampling – including floating vegetations (e.g. duckweed), submerged vegetation and emergent vegetation (i.e. roots/stems below water but leaves above). Leaf litter, debris and other dead vegetation should not be collected. •Collection methods may vary by type of vegetation: o Floating vegetation can be collected from the surface of the water using a net and placed in sampling containers by gloved hand. o Submerged vegetation that is easily loosened from sediment can be disturbed to loosen and removed either using a gloved hand or net. o Emergent aquatic vegetation that can be safely reached from the vessel, can be pulled directly from sediment using a gloved hand and placed in sampling containers. •In the vicinity of the Sampling location, collect any observed floating vegetation first. •Move to the western bank to collect emergent and submerged vegetation as observed. •If limited aquatic vegetation is observed, subsamples from multiple locations can be composited as needed to collect 20-30 grams of tissue, but please discuss with EcoSLEA task lead (Jenn Arblaster) prior to composting. •Once collected, samples should be weight to confirm sample mass, photographed, described in field notes (i.e. % submerged, % floating, % emergent in sample), placed in sampling jars, sealed jars placed into Ziplock bags and placed on ice for transport to lab. 8 COLLECTION AND ANALYSIS OF 6 SAMPLES OF SURFACE SEDIMENT. 8.1 Sample Locations: SED1 through SED6 (Figure 1 SED1 34.850394° -78.826705° SED2 34.848660° -78.825936° SED3 34.843501° -78.823967° SED4 34.837534° -78.823236° SED5 34.831484° -78.822477° SED6 34.822039° -78.820892° 8.2 Sampling Methods: •At each sampling location, a petite ponar will be used to collect a three-point composite of surface sediment. The ponar is approximately 3-4 inches deep and the full depth can be considered ‘surface sediment’. •It may be worthwhile to use a GoPro to observe the sediment bottom for any large debris prior to attempting. Sampling locations can be adjusted as needed to avoid refusal due to debris. If refusal is encountered, sample locations can be moved up to 50 ft as needed in any direction. Record coordinates of all sample locations. •While on station, lower the ponar to collect a grab sample of surface sediment. On vessel, observe the sample for acceptance and photograph (note sample ID in photo). Acceptable samples will have greater than 2 inches of sediment recovery. •In field notes, characterize sediment texture, color (using Munsell chart) and note any odors or sheen. •Using a stainless-steel spoon/scoop, collect sediment avoiding sediment in contact with the sides of the sampler, and place in a stainless-steel bowl for composting. •From within an approximate 25 ft radius of the first grab sample, repeat to collect two more subsamples. •Homogenize sediment until consistent color and texture is achieved removing any large debris (rocks, sticks, shell hash, etc.), and place sample in 2x 16 oz jars and place sealed jars into Ziplock bags. Samples should be sealed and placed on bagged, wet ice for delivery to the laboratory. •All non-dedicated or non-disposable sampling equipment (e.g., stainless steel reusable equipment used in sediment sampling) will be decontaminated between samples (not subsamples in the same composite) in the following manner: Water rinse; Scrub with de-ionized water containing non-phosphate detergent (e.g.,Alconox®); Tap water rinse; and De-ionized water rinse. 9 COLLECTION AND ANALYSIS OF UP TO 3 SAMPLES OF OTHER BENTHIC INVERTEBRATES 9.1 Sampling locations: Sampling locations are flexible and can be determined in the field based on invertebrate abundance. SED locations can be used as starting point for field teams. 9.2 Sampling Methods: •In the general area of each SED sampling location field staff should observe sediment surface for features that would result in refusal, and features like piled/disturbed sediment, burrow holes, or bubbles which may indicate the presence of invertebrates. •When ready to collect a grab sample, lower the ponar to sediment surface and collect a sample. •Place sediment from sampler into a sieve using stainless steel scoop/spoon. Gently sieve out sediments using river water to expose invertebrates, photograph and collect using forceps. Place invertebrates in a sampling container and keep on ice. •If invertebrates are collected at a location, note coordinates with GPS. •Field staff may need to use judgement regarding the success of collecting invertebrates at a specific location and can collect additional grabs or move to a new location as deemed appropriate. •Invertebrates collected from the surrounding area of the same SED location can be directly collected in the same sampling jar (however if a single location results in 15g+ of tissue it should be kept separate as a discrete sample). •As samples are collected from different SED locations, these should be collected in separate jars labeled with the location ID. •At the end of the field day, individual samples will be weighed, and a compositing approach will be determined in coordination with the EcoSLEA task lead (Jenn Arblaster) as needed. Samples will be composited and stored on bagged wet ice until transport to the laboratory. •If insufficient mass for 2-3 samples and pending time in the field, the task leads may request an additional Asian clam sample. Please plan on connecting with Task leads prior to demobilizing. TR0795 November 2019 Figure 1: Proposed Sampling Locations for Benthic Invertebrates and Sediment Samples for Ecological SLEA.

Sample Receipt The following items are noted for this data set: • All samples were received in satisfactory condition and within EPA temperature guidelines on: o August 1, 3, 6, 16, 21, 23, 24, and 28, 2019. o September 13, 17, 25, 27, and 30, 2019 o October 23, 2019 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: • Non-detect results for Byproduct 4, Byproduct 5, PFECA-G, PFMOAA, PFO4DA, and R-EVE in one or more soil or tissue samples were qualified R and are considered to be unusable due to very poor matrix spike (MS) relative percent recoveries (RPR). • The result for PFBS in one tissue sample has been qualified B, and may be biased high, or may be a false positive, because an associated lab method blank contained a comparable concentration. ADQM Data Review Narrative - FAY 2019 SLEA Samp update rev.doc 2 of 3 • Several analytical results have been qualified J as estimated, and non-detect results qualified UJ indicating an estimated reporting limit, due to poor or very poor recovery of surrogate, laboratory blank spike, or matrix spike compounds; sample preparation and/or analysis which exceeded the laboratory hold times; 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. 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. ADQM Data Review Narrative - FAY 2019 SLEA Samp update rev.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 ReportAssociated MS and/or MSD analysis had relative percent recovery (RPR) values less than the data rejection level.
