(electronic copy) 4GOLDER December 30, 2020 20144247 Executive Summary On behalf of Winston-Salem/Forsyth County City/County Utilities Commission (WSFCU), Golder Associates NC, Inc. (Golder) is submitting this Water Quality Monitoring Report, which documents the results from the September 15 - 17, 2020, compliance monitoring event at the closed unlined landfill, the closed Subtitle D landfill, and the active Subtitle D landfill. Naturally occurring concentrations of barium, chromium, and cobalt were addressed in the May 21, 2018, Response to Alternate Source Demonstration - Request for Additional Information, prepared by Golder. Based on a follow up letter from the NC Department of Environmental Quality (DEQ) dated June 8, 2018, two additional background wells (MW-23 and MW-24) were installed to collect additional analytical data to evaluate background concentrations of inorganic constituents and an ASD addendum was submitted following the eighth sampling event. Site -wide, site -specific groundwater protection standards (GPS) were approved by the DEQ on July 8, 2020 as outlined in the ASD addendum for barium, chromium, and cobalt. These standards were used for comparisons to analytical results beginning with the second semi-annual compliance event for 2020. CLOSED UNLINED LANDFILL Vanadium was detected at estimated concentrations below the PQL, but above the NC 2L Interim Maximum Allowable Concentration (IMAC), in samples from two downgradient wells at the closed unlined facility during this event, as it has been historically. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the PQL, the detection of that substance at or above the PQL constitutes a violation of the standard." As these concentrations are estimated below the respective PQLs, no further action is warranted. Eight NC Appendix I volatile organic compounds (VOCs) were detected at concentrations that exceeded their respective PQLs and NC 2L Standards in samples from one or more downgradient wells during the September 2020 event. Benzene was detected in the samples from OW-3, OW-4, and OW-10D at concentrations above the PQL and NC 2L Standard. Constituent 1,4-dichlorobenzene was detected in the samples from OW-3 and OW-4 at concentrations above the PQL and NC 2L Standard. Cis- 1,2-dichloroethene and 1,2-dichloropropane were detected in the samples from OW-3 at concentrations above their respective PQLs and NC 2L Standards. Constituent 1,1-dichloroethane was detected in the samples from OW-1 OD and OW-17D at a concentration above the PQL and NC 2L Standard. Tetrachloroethene was detected in the samples from OW-4 and OW-10D at concentrations above the PQL and NC 2L Standard. Trichloroethene was detected in the samples from OW-4 and OW-10D, at concentrations above the PQL and NC 2L Standard. Vinyl chloride was also detected at concentrations above the PQL and NC 2L Standard, in the samples from OW-3 and OW-4; vinyl chloride was detected at an estimated concentration below the PQL but above the NC 2L Standard at OW-17D. The detected organic constituents and concentrations in groundwater samples from the closed unlined landfill are generally consistent with historical data. The constituent 1,4-dioxane was detected at OW-3 and OW-4 at concentrations above the PQL and NC 2L Standard as it has been previously. This parameter was analyzed as required in the May 29, 2018, memorandum from the NC Department of Environmental Quality and is not required by regulation or permit. CLOSED SUBTITLE D LANDFILL At the closed Subtitle D landfill, vanadium was detected at an estimated concentration below the PQL, but above the IMAC, in the sample from MW-6D during this event. As this concentration is estimated below the PQL, no 4GOLDER December 30, 2020 20144247 further action is warranted. No Appendix I constituents were detected at concentrations above their respective PQLs and groundwater standards during this event. ACTIVE SUBTITLE D LANDFILL At the active Subtitle D landfill, vanadium was detected at concentrations below the PQL, but above the IMAC, in samples from four downgradient wells at the active Subtitle D facility. As these concentrations are estimated below the PQL, no further action is warranted. SURFACE WATER AND LEACHATE Copper and lead were detected at concentrations above their applicable surface water standards during the September event in samples collected from NBC-2, SW-3, and SW-4 for copper and SW-1, SW-3, and SW-4 for lead. As concentrations are higher for upstream monitoring locations, these exceedances do not appear to be related to landfill activities. The Ieachate sampling results are generally consistent with historical data. Based on these results, the WSFCU will continue monitoring the uppermost aquifer beneath the closed unlined landfill in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B .1634 and will continue monitoring the uppermost aquifer beneath the closed and active Subtitle D landfills in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B .1633. The next sampling event is tentatively scheduled for March 2021. y GOLDER iv December 30, 2020 Table of Contents 109s«yzrA 1.0 INTRODUCTION.............................................................................................................................................1 1.1 Site Description and Background.........................................................................................................1 1.2 Compliance Monitoring History............................................................................................................1 1.3 Hydrogeologic Setting..........................................................................................................................3 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION.............................................................3 2.1 Visual Inspection Program...................................................................................................................4 2.2 Well Networks and Groundwater Elevation Measurements................................................................4 2.3 September 2020 Groundwater and Surface Water Monitoring Event.................................................4 2.4 Laboratory Analysis Program...............................................................................................................5 3.0 LABORATORY AND FIELD QA/QC..............................................................................................................5 4.0 DATA EVALUATION......................................................................................................................................5 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons...............................6 4.1.1 Closed Unlined Landfill...................................................................................................................6 4.1.2 Closed Subtitle D Landfill................................................................................................................7 4.1.3 Active Subtitle D Landfill.................................................................................................................7 5.0 CONCLUSIONS..............................................................................................................................................7 6.0 REFERENCES................................................................................................................................................7 TABLES Table 1 Historical Static Water Level Data for the Closed Unlined Landfill Table 2 Historical Static Water Level Data for the Closed Subtitle D Landfill Table 3 Historical Static Water Level Data for the Active Subtitle D Landfill Table 4 Summary of Estimated Horizontal Flow Velocities Table 5 Summary of Well Construction Information Table 6 Summary of Detected Constituents in Monitoring Wells at the Closed Unlined Landfill Table 7 Summary of Field Parameters from Monitoring Wells at the Closed Unlined Landfill Table 8 Summary of Detected Constituents in Surface Water Monitoring Point Table 9 Summary of Field Parameters from Surface Water Monitoring Points Table 10 Summary of Detected Constituents in Monitoring Wells at the Closed Subtitle D Landfill Table 11 Summary of Field Parameters for Monitoring Wells at the Closed Subtitle D Landfill 4 GOLDER v December 30, 2020 Table 12 Table 13 Table 14 DRAWING Drawing 1 APPENDICES Appendix A Appendix B Summary of Detected Constituents in Monitoring Wells at the Active Subtitle D Landfill Summary of Field Parameters for Monitoring Wells at the Active Subtitle D Landfill Summary of Detected Constituents and Field Parameters in Leachate September 15, 2020, Groundwater Surface Contour Map Groundwater and Surface Water Sampling Logs September 2020 Groundwater, Surface Water, and Leachate Certificate -of - Analysis, Chain -of -Custody Forms and Laboratory Data Review 20144247 4GOLDER vi December 30, 2020 20144247 1.0 INTRODUCTION This report summarizes the monitoring results from the September 15 - 17, 2020, groundwater and surface water compliance monitoring event at the Hanes Mill Road Landfill in Winston-Salem, North Carolina (NC) in accordance with Title 15A of the NC Administrative Code (NCAC) Subchapter 13B.1632 and NCAC Subchapter 13B.0544. The Hanes Mill Road Landfill, which comprises a closed, unlined municipal solid waste (MSW) landfill; a closed Subtitle D MSW landfill; and an active Subtitle D MSW landfill, is maintained by the Winston- Salem/Forsyth County City/County Utilities Commission (WSFCU) under Permit No. 34-02 issued by the NC Department of Environmental Quality (DEQ, formerly Department of Environment and Natural Resources). 1.1 Site Description and Background The location of the facility is shown on the inlay on Drawing 1. As presented, the Hanes Mill Road Landfill is located within the boundaries and jurisdiction of the City of Winston-Salem off Hanes Mill Road. The WSFCU operates an approximately 500-acre landfill facility that consists of a closed unlined MSW facility, a closed Subtitle D MSW facility, and an active Subtitle D MSW facility. The facility has been in operation since 1972 under Permit Number 34-02. The closed facility operated as an unlined unit until 1995; between 1995 and 2005, the unit operated as a Subtitle D lined unit that `piggy -backed' over the unlined facility. The unlined and `piggy- backed' areas were closed in 2005. The WSFCU currently operates a Subtitle D facility west of the closed unit. The unlined MSW facility is subject to Assessment Monitoring and Corrective Action in accordance with .1634 through .1637 of the Solid Waste Management Rules (SWMR) and the Transition Plan for the facility. The closed Subtitle D facility and the active Subtitle D MSW facility are subject to water quality monitoring in accordance with the Detection Monitoring Program (.1633 of the SWMR). The landfill is bounded to the south by industrial development, to the north, west, and southwest by residential subdivisions and undeveloped wooded properties, and to the east by U.S. 52. Topographic relief at the landfill ranges from approximately 790 to 940 feet above mean sea level. Surface drainage from the facility is predominantly radial toward several streams along the northern and southern portions of the property that flow into Grassy Creek, which transects the property from north to south and separates the closed landfill and the active landfill. Grassy Creek drains into Mill Creek located south of the Hanes Mill Road Landfill. 1.2 Compliance Monitoring History The WSFCU monitors water quality at the closed, unlined MSW facility by monitoring 10 downgradient monitoring wells (OW-3, OW-4, OW-6, OW-7DA, OW-10D, OW-11, OW-12, OW-13D, OW-14D, and OW-17D) semi-annually. The upgradient monitoring well and surface water sampling points are shared with the `piggy- backed' closed Subtitle D unit as described below. According to correspondence from NC DEQ dated March 4, 2010, NC Appendix II parameters should be monitored once every two years with the next NC Appendix II event being conducted during the spring 2021 event. During the other semi-annual events, analysis of NC Appendix I plus `detects' is required. Based on the March 4, 2010, correspondence, the NC Appendix 11 detects include mercury, tin, dichlorodifluoromethane, and naphthalene. According to correspondence from NC DEQ dated September 22, 2008, approval was granted to reduce the number of, and sampling frequency for, monitored natural attenuation (MNA) parameters and wells to include nitrate, sulfate, chloride, and total organic carbon for wells MW-1 RR, OW-3, OW-4, OW-10D, OW-12, OW-14D, and OW-17D. Every third year (next events in March and September 2021), methane, ethane, and ethene must also be analyzed semi-annually for monitored natural attenuation (MNA) wells, and every fifth year (next events in March and September 2021), hydrogen, sulfide, alkalinity, and volatile fatty acids must also be analyzed semi-annually. 4 GOLDER December 30, 2020 20144247 Based on recent sampling results for the unlined MSW facility, several volatile organic constituents (VOCs) continue to be detected at levels above applicable groundwater standards in samples from one or more monitoring wells. Based on these documented VOC exceedances of applicable groundwater standards, the WSFCU initiated corrective action. The WSFCU monitors water quality at the closed Subtitle D MSW facility by monitoring one upgradient monitoring well (MW-1 RR), and six downgradient monitoring wells (MW-6, MW-6D, MW-7, MW-8, MW-9, and MW-11) semi-annually. Due to historical detections of 1, 1 -dichloroethene in MW-8 at concentrations above the groundwater standard, Assessment Monitoring was initiated for this facility and the first complete Assessment Monitoring background event was conducted in October 2009. The March 2011 event was the fourth of four background events for Assessment Monitoring. The background results indicated that no NC Appendix II constituents were detected above applicable groundwater protection standards in the groundwater at the closed, Subtitle D facility, with the exception of chromium, cobalt, and vanadium, which appear to be representative of background conditions. Per NCAC Subchapter 13B Rule. 1 634(e), the closed Subtitle D facility was to remain in the Assessment Monitoring Program until two consecutive NC Appendix II sampling events indicate that concentrations of all NC Appendix II groundwater concentrations below applicable standards. The September 2012 event was the second of these events; the results indicated that no Appendix II constituents were above background and the closed Subtitle D facility reverted to Detection Monitoring. Two upstream surface water monitoring points (NBC-1 and SW-3) and two downstream monitoring points (NBC-2 and SW-4) are used to monitor both of the closed units and are sampled semi-annually for analysis of NC Appendix I parameters. The WSFCU monitors water quality at the active Subtitle D facility by testing one upgradient monitoring well (MW-12), and seven downgradient monitoring wells (MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-19) semi-annually. Three former piezometers converted to monitoring wells (MW-20, MW-21, and MW-22) were added to the monitoring network as part of the Cell 3/4 expansion. Two surface water points (upstream point SW-1 and downstream point SW-2) are used to monitor the active facility. Samples from the wells and surface water monitoring points are analyzed for NC Appendix I VOCs. A composite leachate sample is collected semi-annually from the two leachate holding tanks for both lined units and analyzed for the approved NC leachate parameter list plus other required parameters. On November 3, 2016, Golder submitted the 14-Day Notification and Alternate Source Demonstration (ASD) to the NC DEQ to address concentrations of barium and cobalt in the sample from monitoring well OW-3 at the closed unlined landfill; arsenic, chromium, and cobalt in samples from monitoring wells MW-6, MW-7, and MW-11 at the closed Subtitle D landfill; and cobalt in the sample from monitoring well MW-19 at the active Subtitle D landfill, which were above their respective NC 2L Standards and Solid Waste Section Limits (SWSLs) during the September 2016. The NC DEQ responded with a Request for Additional Information dated January 18, 2018, which was provided May 21, 2018, as Response to Alternate Source Demonstration - Request forAdditional Information. Based on a follow up letter from the NC DEQ dated June 8, 2018, two additional background wells (MW-23 and MW-24) were installed in November 2018 to collect additional analytical data over a two-year period to evaluate background concentrations of inorganic constituents at the closed unlined landfill, closed Subtitle D landfill, and the active Subtitle D landfill. Naturally occurring concentrations of barium, chromium, and cobalt were addressed in the May 21, 2018, Response to Alternate Source Demonstration - Request for Additional Information, prepared by Golder, which was submitted upon completion of the additional background monitoring. In this document, site -wide, site -specific groundwater protection standards (GPS) were presented and subsequently approved by the NC DEQ on July 8, 2020 for barium, chromium, and cobalt. These standards were used for comparisons to analytical results beginning with the second semi-annual compliance event for 2020. 4 GOLDER December 30, 2020 20144247 1.3 Hydrogeologic Setting Geologically, the facility is located within the Carolina Slate Belt of the central Piedmont Physiographic Province of North Carolina (NCGS, 1985 and 2004). The Carolina Slate Belt is comprised of late Proterozoic to Cambrian volcanic and sedimentary rocks that have been metamorphosed to lower greenschist facies by plutons (Butler and Secor, 1991). The facility is underlain primarily by the Ashe Formation, which consists of fine grained, thinly layered sulfidic biotite-muscovite gneiss interlayered with mica schist and phyllite. The Ashe Formation also consists of amphibolite and garnet amphibolite (HDR, 2003). The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of partially weathered, fractured, metamorphic intrusive rock. Groundwater occurs at depths ranging from approximately 3 to 62 feet below grade. Depth -to -water measurements obtained during the September 2020 monitoring event are summarized in Tables 1 through 3 and were used to prepare a groundwater surface contour map presented as an overlay on Drawing 1. As presented, the groundwater flow in the uppermost aquifer beneath the closed landfills is generally toward the southwest toward Grassy Creek, which separates the closed facility from the active facility. Groundwater flow in the uppermost aquifer beneath the active landfill is semi -radial, flowing primarily east toward Grassy Creek, but also north and south to tributaries of Grassy Creek. The groundwater contour map and interpreted flow directions are generally consistent with previously submitted groundwater contour maps and flow directions. Based on the September 15, 2020, groundwater surface contour map, the average hydraulic gradient in the shallow aquifer underlying the closed landfills was calculated to be approximately 0.02 foot/foot (Table 4). The hydraulic gradient underlying the active landfill was calculated to be approximately 0.04 foot/foot (Table 4). The hydraulic gradient calculations are consistent with values from previous reports. A hydraulic conductivity of 5.68E-04 centimeters/second is used based on an average of previous hydraulic conductivities calculated for the unconsolidated upper aquifer (HDR, 2003). An estimated effective porosity of 0.20 was used for the shallow aquifer to represent a range from saprolite to fractured rock (HDR, 2003). Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was calculated using the following modified Darcy equation: V9w = Ki/ne where V9w = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. The average estimated linear groundwater flow velocity under the closed landfills is approximately 61 feet/year and the average estimated linear groundwater flow velocity under the active landfill is approximately 118 feet/year (Table 4). The range of groundwater flow is expected to vary depending on the hydrogeologic unit in which it occurs. However, the linear velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this equation represents a likely average value for the uppermost aquifer and does not account for heterogeneous and/or anisotropic conditions that may be present in the uppermost aquifer at the facility. 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION Field activities conducted for the September 2020 sampling event are discussed in the following sections 4 GOLDER December 30, 2020 20144247 2.1 Visual Inspection Program In order to ensure that a potential release is detected at the earliest possible time, the visual inspection program is used by sampling personnel at the Hanes Mill Road Landfill. This program includes physical indicators such as potential water table mounding beneath the waste management unit, physical examination of any stresses in biological communities, visible signs of leachate migration (i.e., leachate seeps), unexplained changes in soil characteristics, and any other change to the environment due to the waste management units. During the September 2020 monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management areas. 2.2 Well Networks and Groundwater Elevation Measurements The network of groundwater monitoring wells at the closed unlined landfill consists of one upgradient monitoring well (MW-1 RR) and 10 downgradient monitoring wells (OW-3, OW-4, OW-6, OW-7DA, OW-10D, OW-11, OW-12, OW-13D, OW-14D, and OW-17D) and are monitored during each semi-annual monitoring event. Four surface water monitoring points (NBC-1, NBC-2, SW-3, and SW-4) are monitored semi-annually. Monitoring well and surface water point locations are shown on Drawing 1. Monitoring wells OW-3, OW-4, OW-6, OW-11, and OW-12 are screened in the shallow, unconfined aquifer. Monitoring wells MW-1 RR, OW-7DA, OW-10D, OW-13D, OW-14D, and OW-17D are screened in fractured bedrock. Two additional upgradient monitoring wells (MW-23 and MW-24) were installed in 2018 to collect additional background data for the saprolite aquifer. A summary of well construction details is provided in Table 5. The network of groundwater monitoring wells at the closed Subtitle D landfill consists of six downgradient monitoring wells (MW-6, MW-6D, MW-7, MW-8, MW-9, and MW-11). The upgradient monitoring well (MW-1 RR) and surface water sampling points (NBC-1, NBC-2, SW-3, and SW-4) are shared by the closed unlined landfill. Monitoring wells MW-6, MW-7, MW-8, and MW-11 are screened in the shallow, unconfined aquifer. Monitoring wells MW-6D and MW-9 are screened across saprolite and partially weathered rock. A summary of well construction details is provided in Table 5 The network of groundwater monitoring wells at the active Subtitle D landfill consists of one upgradient monitoring well (MW-12), and 10 downgradient monitoring wells (MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-19, MW-20, MW-21, and MW-22). Two surface water points (SW-1 and SW-2) are used to monitor the active facility. Monitoring wells MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-19, MW-20, and MW-22 are screened in the shallow, unconfined aquifer. Monitoring well MW-21 is screened in fractured bedrock. Upgradient monitoring well MW-12 is screened in fractured bedrock. A summary of well construction details is provided in Table 5. Depth -to -water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. A summary of the historical water level elevations is presented in Tables 1 through 3. As presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is generally consistent, with an average variation of approximately 1.5 feet. 2.3 September 2020 Groundwater and Surface Water Monitoring Event Golder visited the facility on September 15 - 17, 2020, to purge and sample the 30 monitoring wells, sample the six surface water monitoring points, and sample the facility leachate at the closed and active landfills. Monitoring wells were purged and sampled with a combination of portable and dedicated pumps and micropurge procedures as described in Section 2.3. 4 GOLDER December 30, 2020 20144247 The surface water samples were collected directly from stream flow, by lowering the sample containers into the stream with the opening facing away from the current flow, taking care to prevent the overflow of the sample containers and to minimize sample -induced turbidity. Measurements of pH, specific conductivity, dissolved oxygen, oxidation-reduction potential, temperature, and turbidity were recorded during the collection of the surface water samples. A composite leachate sample was collected from Tank A and Tank B. The leachate holding tanks collect leachate from both lined facilities. Measurements of pH, specific conductivity, and temperature were recorded during the collection of the leachate sample. After collection, the surface water and leachate samples were placed in a cooler on ice, under chain -of -custody control. Copies of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, sampling location, sampling method, field observations, and water quality measurements. 2.4 Laboratory Analysis Program The groundwater, surface water, and leachate samples from the September 2020 event were shipped to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control, and were received within the dates of September 16 - 18, 2020. The samples were received at the laboratory in good condition and properly preserved. Groundwater samples from OW-6, OW-7DA, OW-11, and OW-13D at the closed unlined landfill were analyzed for the NC Appendix I list of parameters plus mercury; tin; dichlorofluoromethane; naphthalene; and 1,4-dioxane. Groundwater samples from MW-1RR, OW-3, OW-4, OW-1 OD, OW-12, OW-14D, and OW-17D at the closed unlined landfill were analyzed for the NC Appendix I list of parameters plus mercury; tin; dichlorofluoromethane; naphthalene; 1,4-dioxane; and required MNA indicator parameters. Groundwater samples from the Subtitle D landfills (active and closed) were analyzed for the NC Appendix I list of parameters and 1,4-dioxane per the May 29, 2018, NC DEQ memorandum. Samples from background wells MW-23 and MW-24 were analyzed for the NC Appendix II list of metals. Surface water samples were analyzed for the NC Appendix I list of parameters and 1,4-dioxane. The leachate sample was analyzed for the NC leachate list of parameters and other permit -required parameters. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the September 2020 groundwater, surface water, and leachate sampling event. In addition to the field blank, laboratory -prepared trip blanks accompanied the volatile sample containers for the September 2020 sampling event to and from the laboratory. ENCO analyzed the field and trip blanks for the NC Appendix I list of parameters plus applicable NC Appendix II detects. Reviews of the laboratory data were performed by Golder personnel and are presented in Appendix B. Bromoform and dibromochloromethane were detected in the trip blank and copper in the field blank. Based on data reviews performed by Golder, detections in samples from NBC-1, SW-1, OW-3, OW-4, OW-10D, OW-14D, OW-17D, MW-6, MW-12, MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-19, MW-21 are considered blank -qualified. Bromoform and dibromochloromethane were possible sample vial contaminations as noted in the laboratory reports. Therefore, all detections of these constituents were blank -qualified. There were no other concentrations reported above laboratory detection limits in the field blank, trip blanks, or laboratory method blanks. A n DATA EVALUATION The results of the data evaluations are presented in the following sections. GOLDER December 30, 2020 20144247 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons The concentrations of detected inorganic and organic constituents in samples collected from monitoring wells at each landfill were compared to their applicable NC 2L Water Quality Standards (NC 2L Standards) or Interim Maximum Allowable Concentrations (IMACs). Concentrations of NC Appendix I inorganic and organic constituents in samples collected from surface water monitoring points were compared to applicable surface water standards. The results of comparisons to groundwater and surface water quality standards are presented in the following sections. 4.1.1 Closed Unlined Landfill Analytical results for the September 2020 groundwater samples at the closed unlined landfill are summarized in Table 6. Field parameters for the groundwater samples at the closed unlined landfill are summarized in Table 7. Analytical results for the September surface water samples are summarized in Table 8. Field parameters for the surface water samples are summarized in Table 9. The laboratory certificates -of -analysis, chain -of -custody form, and laboratory data reviews for the sampling event are included in Appendix B. Vanadium was detected at estimated concentrations below the PQL, but above the IMAC, in the samples from downgradient wells OW-7DA and OW-14D. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the practical quantitation limit (PQL), the detection of that substance at or above the PQL constitutes a violation of the standard." The groundwater standard for cobalt is 10 micrograms per liter (ug/L) and the groundwater standard for vanadium is 0.3 ug/L. As presented, the concentrations mentioned above were reported below the PQLs and are considered estimated (i.e., not quantifiable). As these concentrations are estimated below the PQL, no further action is warranted. Eight NC Appendix I VOCs were detected at concentrations that exceeded their respective PQLs and NC 2L Standards in samples from one or more downgradient wells during the September 2020 event. Benzene was detected in the samples from OW-3, OW-4, and OW-1 OD at concentrations above the PQL and NC 2L Standard. Constituent 1,4-dichlorobenzene was detected in the samples from OW-3 and OW-4 at concentrations above the PQL and NC 2L Standard. Cis- 1,2-dichloroethene and 1,2-dichloropropane were detected in the samples from OW-3 at concentrations above their respective PQLs and NC 2L Standards. Constituent 1, 1 -dichloroethane was detected in the samples from OW-1 OD and OW-17D at a concentration above the PQL and NC 2L Standard. Tetrachloroethene was detected in the samples from OW-4 and OW-10D at concentrations above the PQL and NC 2L Standard. Trichloroethene was detected in the samples from OW-4 and OW-10D, at concentrations above the PQL and NC 2L Standard. Vinyl chloride was also detected at concentrations above the PQL and NC 2L Standard, in the samples from OW-3 and OW-4; vinyl chloride was detected at an estimated concentration below the PQL but above the NC 2L Standard at and OW-17D. The detected organic constituents and concentrations in groundwater samples from the closed unlined landfill are generally consistent with historical data. The constituent 1,4-dioxane was also detected at OW-3 and OW-4 above the PQL and NC 2L Standard during this event. However, this parameter is not required by regulation or permit and was analyzed as required in the May 29, 2018, memorandum from the NC DEQ. Copper and lead were detected above their applicable surface water standards during the September event in samples collected from NBC-2, SW-3, SW-4 and SW-1 for copper and SW-3, SW-4 and SW-1 for lead. As concentrations are higher for upstream monitoring locations, these exceedances do not appear to be related to landfill activities. The leachate sampling results are generally consistent with historical data. GOLDER December 30, 2020 20144247 4.1.2 Closed Subtitle D Landfill Analytical results for the September 2020 groundwater samples at the closed Subtitle D landfill are summarized in Table 10. Field parameters for the groundwater samples at the closed Subtitle D landfill are summarized in Table 11. The laboratory certificates -of -analysis, chain -of -custody form, and laboratory data reviews for the sampling event are included in Appendix B. Vanadium was detected at estimated concentrations below the PQL, but above the IMAC, in the sample from and downgradient well MW-6D. As this concentration is estimated below the respective PQLs, no further action is warranted. 4.1.3 Active Subtitle D Landfill Analytical results for the September groundwater samples at the active Subtitle D landfill are summarized in Table 12. Field parameters for the groundwater samples at the active Subtitle D landfill are summarized in Table 13. The laboratory certificates -of -analysis, chain -of -custody form, and laboratory data reviews for the sampling event are included in Appendix B. As presented, vanadium was detected at estimated concentrations below the PQL, but above the IMAC, in the samples from downgradient wells MW-14, MW-15, MW-16, and MW-17. As these concentrations are estimated below the PQL, no further action is warranted. Concentrations of detected constituents were generally consistent with historical data. 5.0 CONCLUSIONS Due to the continued presence of VOCs at concentrations above applicable groundwater standards in monitoring wells associated with the closed unlined landfill, the WSFCU will continue to monitor that unit in accordance with the requirements of the Corrective Action Plan. The WSFCU will continue monitoring the uppermost aquifer beneath the closed unlined landfill in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B .1634 and will continue monitoring the uppermost aquifer beneath the closed and active Subtitle D landfills in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B .1633. The next compliance monitoring event for this facility is tentatively scheduled for March 2021. n.0 REFERENCES Butler, J.R., and D.T. Secor, Jr., 1991. The Central Piedmont (Chapter 4) in J.W.

Unless otherwise noted in an attached project narrative, all samples were received in acceptable condition and processed in accordance with the referenced methods/procedures. Results for these procedures apply only to the samples as submitted. The analytical results contained in this report are in compliance with NELAC standards, except as noted in the project narrative if applicable. This report shall not be reproduced except in full, without the written approval of the Laboratory. This report contains only those analyses performed by Environmental Conservation Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from outside organizations will be reported under separate cover. If you have any questions or require further information, please do not hesitate to contact me. Sincerely, Amanda L. Gaines Project Manager Enclosure(s) FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.

(G0007) Project: Hanes Mill LF- Closed Unlined Lab ID: CD15082 Overview (� �Eo www.encolabs.com This report is an amendment to the original report dated September 30, 2020 for this work order. This report was revised, at the client's request, to address the unusual detections in the 8260D analysis Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D LCS exhibited a high bias for 1, 1 -Dichloroethene, Bromodichloromethane, Carbon disulfide, and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichloroethene, Acetone, Bromochloromethane, Bromomethane, Carbon disulfide, Chloroethane, cis- 1,2-Dichloroethene, lodomethane, Methylene chloride, trans- 1,3-Dichloropropene, Trichlorofluoromethane, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for 1,1,1-Trichloroethane, 1,1-Dichloroethene, Bromodichloromethane, Carbon tetrachloride, Chlorobenzene, and Trichlroethene, were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of 1, 1 -Dichloroethene, Benzene, Chlorobenzene, and Toluene exceeded acceptance criteria; however, these analytes were not detected in the associated samples. The spike recoveries for Antimony and Thallium were outside control limits for the MS, MSD, and/or Post Digestion spike samples. The QC batches were approved based on acceptable LCS recovery of these analytes Quality Control Remarks No Comments Other Comments At the client's request, the reported detections of Bromoform and Dibromochloromethane in the 8260D analyses were investigated. Laboratory sources of contamination were eliminated, and the contamination is suspected to have originated in the sample vials, batch lot number 25072050. All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

(G0007) Project: Hanes Mill LF- Closed Unlined MNA Lab ID: CD15083 Overview (� �Eo www.encolabs.com This report is an amendment to the report dated October 19, 2020 for this work order. This report was revised, at the client's request, to include the 8260D results for 3402-MW-1 RR. This report is an amendment to the original report dated September 29, 2020 for this work order. This report was revised, at the client's request, to address the unusual detections in the 8260D analysis. Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D LCS exhibited a high bias for 1, 1 -Dichloroethene, Acetone, Bromodichloromethane, Carbon disulfide, cis- 1,2-Dichloroethene, Dibromomethane, and Trichloroethene; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichloroethene, Bromochloromethane, Bromomethane, Carbon disulfide, Chloroethane, Chloroform, Idomethane, Methylene chloride, Trichlorofluoromethane, Vinyl Acetate, Vinyl chloride, and Dichlorofluoromethane; however, these analytes were not detected in the associated samples. The spike recoveries for Benzene, Chlorobenzene, Toluene, Trichloroethene, and 1,4-Dioxane were outside control limits for the MS and MSD samples, the precision between duplicate spikes of Benzene, Chlorobenzene, Toluene, and Trichloroethene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recovery and precision between duplicate spike samples for 1, 1 -Dichloroethene was outside control limits for the MS and MSD samples; however, this analyte was not detected in the associated samples. The spike recoveries for Chloride and Nitrate/Nitrite were outside control limits for the MS and/or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks No Comments Other Comments At the client's request, the reported detections of Bromoform and Dibromochloromethane in the 8260D analyses were investigated. Laboratory sources of contamination were eliminated, and the contamination is suspected to have originated in the sample vials, batch lot number 25072050. All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

I Page 49 Of 53 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported.

(G0007) Project: Hanes Mill LF- Closed Sub D Lab ID: CD15081 Overview (� �Eo www.encolabs.com This report is an amendment to the original report dated September 30, 2020 for this work order. This report was revised, at the client's request, to address the unusual detections in the 8260D analysis Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D LCS exhibited a high bias for 1, 1 -Dichloroethene, Bromochloromethane, Carbon disulfide, cis- 1,2-Dichloroethene, Methylene chloride, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1, 1 -Dichloroethene, Acetone, Bromochloromethane, Bromomethane, Carbon disulfide, Chloroethane, lodomethane, Methylene chloride, trans- 1,3-Dichloropropene, Trichlorofluoromethane, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for 1,1-Dichloroethene, Bromochloromethane, Carbon disulfide, Chlorobenzene, Chloroethane, Methylene chloride, Trichlroethene, and Vinyl chloride were outside control limits for the MS, MSD, and/or Post Digestion spike samples, the precision between duplicate spikes of 1,1-Dichloroethene, Benzene, Chlorobenzene, and Toluene exceeded acceptance criteria; however, these analytes were not detected in the associated samples. The spike recoveries for Antimony and Thallium were outside control limits for the MS, MSD, and/or Post Digestion spike samples. The QC batches were approved based on acceptable LCS recovery of these analytes Quality Control Remarks No Comments Other Comments At the client's request, the reported detections of Bromoform and Dibromochloromethane in the 8260D analyses were investigated. Laboratory sources of contamination were eliminated, and the contamination is suspected to have originated in the sample vials, batch lot number 25072050. All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

I Page 20 Of 23 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact. R-04 The Reporting Limits for this analysis are elevated due to sample foaming. FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.

(G0007) Project: Hanes Mill LF- Active Sub D Lab ID: CD15079 Overview (� �Eo www.encolabs.com This report is an amendment to the original report dated October 2, 2020 for this work order. This report was revised, at the client's request, to address the unusual detections in the 8260D analysis. Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D LCS exhibited a high bias for 1,1-Dichloroethene, Carbon disulfide, and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichloroethene, 1,2-Dibromo-3-chloropropane, 1,2-Dichloroethane, Acetone, Bromochloromethane, Bromomethane, Carbon Disulfide, Carbon tetrachloride, Chloroethane, Chloroform, Chloromethane, cis- 1,2-Dichloroethene, Idomethane, Methylene chloride, trans-1,3-Dichloropropene, trans- 1,4-Dichloro-2-butene, Trichlorofluoromethane, Vinyl acetate, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene, and Trichloroethene were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of Benzene, Chlorobenzene, and Toluene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recovery for 1, 1 -Dichloroethene was outside control limits for MS and MSD samples; however, this analyte was not detected in the associated samples. Quality Control Remarks No Comments Other Comments At the client's request, the reported detections of Bromoform and Dibromochloromethane in the 8260D analyses were investigated. Laboratory sources of contamination were eliminated, and the contamination is suspected to have originated in the sample vials, batch lot number 25072050. All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

All detects for blanks are listed below by constituent. All laboratory method blanks, if any, have been `flagged' with a `B' where detected in other samples as appropriate and a laboratory narrative was provided. If the sample was flagged by the laboratory and is not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory contaminants -acetone, methylene chloride and phthalates), list below with explanation if flags should be removed. If flags need to be added for samples, also list below.
