(Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the September 11 - 14, 2017, compliance monitoring event at the closed unlined landfill, the closed Subtitle D landfill, and the active Subtitle D landfill, and the December 20, 2017, verification sampling event at the active Subtitle D landfill at the above-referenced facility. At the closed unlined landfill, two inorganic constituents (barium and cobalt) were detected at concentrations above their respective Solid Waste Section Reporting Limits (SWSLs) and applicable groundwater standards in the sample from OW-3. The concentrations of barium and cobalt are below the proposed site-specific groundwater protection standards presented in the November 3, 2016, 14-day Notification and Alternate Source Demonstration (ASD) and referenced in the May 15, 2017, 14-day Notification. The ASD provided data to support that barium and cobalt are naturally occurring and no further action is warranted. Eight NC Appendix I volatile organic compounds (VOCs) (benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; cis-1,2-dichloroethene; 1,2-dichloropropane; tetrachloroethene; trichloroethene; and vinyl chloride) were detected at concentrations that exceeded their respective SWSLs and NC 2L Standards in samples from one or more downgradient wells during the September 2017 event. The concentrations of VOCs detected in groundwater samples from the closed unlined landfill are generally consistent with historical data. At the closed Subtitle D landfill, two NC Appendix I inorganic constituents (chromium and cobalt) were detected above their respective SWSLs and applicable groundwater standards in samples from one or more downgradient monitoring wells during the September 2017 event. The concentrations of chromium and cobalt are below the proposed site-specific groundwater protection standards presented in the November 3, 2016, 14-day Notification and ASD and referenced in the May 15, 2017, 14-day Notification. The ASD provided data to support that chromium and cobalt are naturally occurring and no further action is warranted. No NC Appendix I VOCs were detected in groundwater samples above applicable groundwater standards during this event at the closed Subtitle D facility. At the active Subtitle D landfill, cobalt and silver were detected at concentrations that exceeded their respective SWSLs and applicable groundwater standards from one or more downgradient monitoring wells during the September 2017 event. The concentration of cobalt is below the proposed site-specific groundwater protection standard presented in the November 3, 2016, 14-day Notification and ASD and referenced in the May 15, 2017, 14-day Notification. The ASD provided data to support that cobalt is naturally occurring and no further action is warranted. The concentration of silver in the sample from MW-22 was considered suspect based on historical data and a verification sampling event was performed on December 20, 2017. Silver was detected at an estimated January 2018 i Project No. 0939-668717 Table of Contents COVER LETTER 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 ............................................... 4 2.1 Visual Inspection Program ........................................................................................................... 4 2.2 Well Networks and Groundwater Elevation Measurements ........................................................ 4 2.3 September 2017 Groundwater and Surface Water Monitoring Event ......................................... 5 2.5 Laboratory Analysis Program ....................................................................................................... 6 2.6 September 2017 Sampling Results ............................................................................................. 7 2.6.1 Closed Unlined Landfill ............................................................................................................ 7 2.6.2 Closed Subtitle D Landfill ......................................................................................................... 7 2.6.3 Active Subtitle D Landfill .......................................................................................................... 8 3.0 LABORATORY AND FIELD QA/QC ................................................................................................ 8 4.0 DATA EVALUATION ........................................................................................................................ 9 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons ....................... 9 4.1.1 Closed Unlined Landfill ............................................................................................................ 9 4.1.2 Closed Subtitle D Landfill ....................................................................................................... 10 4.1.3 Active Subtitle D Landfill ........................................................................................................ 11 5.0 CONCLUSIONS ............................................................................................................................. 11 6.0 REFERENCES ............................................................................................................................... 12 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 Table 12 Summary of Detected Constituents in Monitoring Wells at the Active Subtitle D Landfill Table 13 Summary of Field Parameters for Monitoring Wells at the Active Subtitle D Landfill Table 14 Summary of Detected Constituents and Field Parameters in Leachate Table 15 Summary of Previously Proposed Groundwater Protection Standards January 2018 ii Project No. 0939-668717 Drawings Drawing 1 September 11, 2017, Groundwater Surface Contour Map Appendices Appendix A Groundwater and Surface Water Sampling Logs Appendix B September 2017 and December 2017 Groundwater, Surface Water, and Leachate Certificate-of-Analysis, Chain-of-Custody Forms and Laboratory Data Review January 2018 1 Project No. 0939-668717 1.0 INTRODUCTION This report summarizes the monitoring results from the September 11 - 14, 2017, groundwater and surface water sampling and analysis event, and December 20, 2017, verification sampling 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 (CCUC) 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 CCUC 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 CCUC 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 CCUC 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 January 2018 2 Project No. 0939-668717 next NC Appendix II event being conducted during the spring 2019 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 II 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-1RR, OW-3, OW-4, OW-10D, OW-12, OW-14D, and OW-17D. Every third year (next events in 2018), methane, ethane, and ethene must also be analyzed semi-annually for MNA wells, and every fifth year (events in March and September 2021), hydrogen, sulfide, alkalinity, and volatile fatty acids must also be analyzed semi-annually. 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 CCUC initiated corrective action. The CCUC monitors water quality at the closed Subtitle D MSW facility by monitoring one upgradient monitoring well (MW-1RR), 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.1634(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. Therefore, 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 CCUC 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 January 2018 3 Project No. 0939-668717 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. 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 4 to 60 feet below grade. Depth-to-water measurements obtained during the September 2017 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 11, 2017, 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: Vgw = Ki/ne January 2018 4 Project No. 0939-668717 where Vgw = 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 56 feet/year and the average estimated linear groundwater flow velocity under the active landfill is approximately 121 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 2017 sampling event and the December 2017 verification sampling event are discussed in the following sections. 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 and December 2017 monitoring events, 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-1RR) 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-1RR, OW-7DA, OW-10D, OW-13D, OW-14D, and OW-17D are screened in fractured bedrock. 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-1RR) 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 January 2018 5 Project No. 0939-668717 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 are presented in Tables 1 through 3. As presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with an average variation of approximately 1.5 feet. 2.3 September 2017 Groundwater and Surface Water Monitoring Event Golder visited the facility on September 11 - 14, 2017, to purge and sample the 28 monitoring wells, sample the six surface water monitoring points, and sample the facility leachate at the closed and active landfills. Depth-to-water measurements were obtained from the monitoring wells to the nearest 0.01 foot using an electronic water level indicator prior to purging the wells. Monitoring wells were purged and sampled with a combination of portable and dedicated pumps and micropurge procedures. Measurements of pH, specific conductivity, dissolved oxygen, oxidation-reduction potential, temperature, and turbidity were recorded on approximately 3- to 5-minute intervals during the purge, depending on the purge rate. In general, the purge rate for each well was matched to the yield of the monitoring well, as determined by continuously monitoring the depth to water, up to a maximum purge rate of 300 milliliters per minute. Purging was continued until stabilization was indicated by the field parameters. Prior to sampling, the laboratory-supplied sample containers were prepared. Each sample container was labeled with the sample identification number, sampling personnel, date and time of sample collection, project name and number, and requested chemical analyses. The required groundwater samples were collected directly from the pump discharge lines in the labeled, laboratory-supplied, pre-preserved sample containers after purging was completed based on stabilization of all field parameters. After collection, the samples were placed in a cooler on ice, under chain-of-custody January 2018 6 Project No. 0939-668717 control. Copies of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling location, sampling equipment, sampling method, field observations, and field parameters. 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 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 December 2017 Verification Groundwater Monitoring Event Golder personnel visited the facility on December 20, 2017, to re-sample MW-22 at the active Subtitle D landfill to verify the silver concentration observed during the September 2017 event. The sample was collected utilizing techniques as those described above. After collection, the sample was placed in a cooler on ice, under chain-of-custody control. A copy of the sampling log is included in Appendix A. Included on the log is a description of the sampling equipment, sampling method, field observations, location, and water quality measurements. 2.5 Laboratory Analysis Program The groundwater, surface water, and leachate samples were shipped to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain-of-custody control, and were received within the dates of September 12 - 15, 2017, and December 21, 2017. 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, and naphthalene. Groundwater samples from MW-1RR, OW-3, OW-4, OW-10D, 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, 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. Surface water samples were analyzed for the NC Appendix I list of January 2018 7 Project No. 0939-668717 parameters. The leachate sample was analyzed for the NC leachate list of parameters and other permit- required parameters. 2.6 September 2017 Sampling Results Analytical results from groundwater, surface water, and leachate samples from the September water quality monitoring event are presented in the following sections. 2.6.1 Closed Unlined Landfill Analytical results for the September 2017 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 2017 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. At the closed unlined landfill, two inorganic constituents (barium and cobalt) were detected at concentrations above their respective Solid Waste Section Limits (SWSLs) in samples from one or more downgradient monitoring wells during the September 2017 sampling event. Ten VOCs (benzene; chlorobenzene; 1,4-dichlorobenzene; dichlorodifluoromethane; 1,1-dichloroethane; cis-1,2-dichloroethene; 1,2-dichloropropane; tetrachloroethene; trichloroethene; and vinyl chloride) were detected at concentrations that exceeded their respective SWSLs in samples from one or more downgradient wells during the September 2017 event. The concentrations of VOCs in groundwater samples from the closed unlined landfill are generally consistent with historical data. There were no NC Appendix I constituents detected above the SWSL in surface water monitoring points associated with the closed unlined landfill and the closed Subtitle D landfill during the September 2017 event. Detected constituents and concentrations are generally consistent with historical data. 2.6.2 Closed Subtitle D Landfill Analytical results for the September 2017 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. Four NC Appendix I inorganic constituents (barium, chromium, cobalt, and lead) were detected above their respective SWSLs in samples from one or more downgradient monitoring wells during the September 2017 event. No NC Appendix I VOC’s were detected above their respective SWSLs in samples from downgradient wells at the closed Subtitle D landfill during the September 2017. January 2018 8 Project No. 0939-668717 There were no NC Appendix I constituents detected above the SWSL in surface water monitoring points associated with the closed unlined landfill and the closed Subtitle D landfill during the September 2017 event. Detected constituents and concentrations are generally consistent with historical data. The surface water analytical results are summarized in Table 8 and the field parameters are summarized in Table 9. The leachate sampling results are summarized in Table 14. Concentrations of detected constituents were generally consistent with historical data. 2.6.3 Active Subtitle D Landfill Analytical results for the September 2017 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. At the active Subtitle D landfill, three NC Appendix I inorganic constituents (barium, cobalt, and silver) were detected at concentrations above the SWSLs in samples from one or more downgradient monitoring wells during the September 2017 event. The detection of silver in the sample from MW-22 is considered suspect due to the concentration being much higher than historical. A re-sampling event was performed on December 20, 2017, to verify the silver detection at MW-22. No NC Appendix I organic constituents were detected in groundwater samples above the SWSLs during this event at the active Subtitle D facility. As presented on Table 8, no NC Appendix I constituents were detected above the SWSLs from surface water points associated with the active Subtitle D landfill during the September 2017 event. The surface water analytical results are summarized in Table 8 and the field parameters are summarized in Table 9. The leachate sampling results are summarized in Table 14. Concentrations of detected constituents were generally consistent with historical data. 2.7 December 2017 Verification Sampling Results As presented, silver for MW-22 at the active Subtitle D landfill was not confirmed during the December 2017 verification event as it was detected at a concentration that was an order of magnitude below the September 2017 concentration. The original silver concentration for the September 2017 event is considered suspect. The laboratory certificates-of-analysis, chain-of-custody form, and laboratory data reviews for the sampling event are included in Appendix B. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the September 2017 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 2017 sampling event to and from the laboratory. ENCO January 2018 9 Project No. 0939-668717 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. Barium, copper, and tin were detected at estimated concentrations in the field blank and zinc was detected at estimated concentrations in the laboratory method blank. Based on data reviews performed by Golder, the concentrations in the following are considered blank-qualified: barium in samples from OW-7DA and OW-13D; copper in samples from MW-7, MW-15, MW-17, MW-22, SW-1, and SW-2; and zinc in samples from OW-3, OW-4, OW-6, OW-11, MW-7, MW-8, MW-9, MW-11, MW-13, MW-14, MW-15, MW-16, MW-17, MW-20, MW-22, SW-1, SW-2, SW-3, SW-4, and leachate. 4.0 DATA EVALUATION The results of the data evaluations are presented in the following sections. 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 are to be compared to their applicable NC 2L Water Quality Standards (NC 2L Standards) or Solid Waste Section Groundwater Protection Standards (GWPS). Concentrations of NC Appendix I inorganic and organic constituents in samples collected from surface water monitoring points are to be 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 As presented in Table 6, two inorganic constituents (barium and cobalt) were detected at concentrations above their respective SWSLs and applicable groundwater standards in the sample from OW-3 at the closed unlined facility. The concentrations of barium and cobalt are below the proposed site-specific groundwater protection standards presented in the November 3, 2016, 14-day Notification and Alternate Source Demonstration (ASD) and referenced in the May 15, 2017, 14-day Notification, which are summarized on Table 15. The ASD provided data to support that barium and cobalt are naturally occurring and no further action is warranted. Cobalt was also detected at concentrations below the SWSL, but above the GWPS, in the sample from downgradient well OW-4. Thallium was also detected at concentrations below the SWSL, but above the GWPS, in samples from upgradient well MW-1RR and downgradient wells OW-4, OW-7DA, OW-11, and OW-17D. Vanadium was detected at concentrations below the SWSL, but above the GWPS, in samples from wells OW-7DA, OW-10D, and OW-14D. Because these concentrations of cobalt, thallium, and vanadium are estimated below the SWSLs, no further action is warranted for these detections. January 2018 10 Project No. 0939-668717 Eight NC Appendix I volatile organic compounds (VOCs) (benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; cis-1,2-dichloroethene; 1,2-dichloropropane; tetrachloroethene; trichloroethene; and vinyl chloride) were detected at concentrations that exceeded their respective SWSLs and NC 2L Standards in samples from one or more downgradient wells during the September 2017 event. Benzene; 1,4-dichlorobenzene; cis-1,2-dichloroethene; 1,2-dichloropropane; and vinyl chloride were detected in the samples from OW-3 at concentrations above their respective SWSLs and NC 2L Standards. Constituent 1,4-dichlorobenzene was detected in the sample from OW-4 at a concentration above its SWSL and NC 2L Standard. Constituent 1,1-dichloroethane was detected in the sample from OW-10D at a concentration above its SWSL and NC 2L Standard. Tetrachlorothene was detected in the samples from OW-4 and OW-10D at concentrations above the SWSL and NC 2L Standard. Trichloroethene was detected in the samples from OW-4, OW-10D, OW-17D at concentrations above the SWSL and NC 2L Standard. Constituent 1,2-dichloroethane was detected at an estimated concentration above the NC 2L Standard, but below the SWSL, in the samples from OW-3 and OW-4. No additional actions are warranted for these estimated concentrations. The concentrations of organic constituents in groundwater samples from the closed unlined landfill are generally consistent with historical data. As presented in Table 8, no NC Appendix I inorganic or organic constituents were detected above their applicable surface water standards in surface water monitoring points associated with the closed unlined landfill during the September 2017 event. 4.1.2 Closed Subtitle D Landfill As presented in Table 10, two NC Appendix I inorganic constituents (chromium and cobalt) were detected above their respective SWSLs and applicable groundwater standards in samples from one or more downgradient monitoring wells during the September 2017 event at the closed Subtitle D facility. Chromium was detected above the SWSL and NC 2L Standard in the sample from MW-11. Cobalt was detected at concentrations above the SWSL and NC 2L Standard in the samples from MW-6. The concentrations of chromium and cobalt are below the proposed site-specific groundwater protection standards presented in the November 3, 2016, 14-day Notification and ASD and referenced in the May 15, 2017, 14-day Notification (Table 15). The ASD provided data to support that chromium and cobalt are naturally occurring and no further action is warranted. Cobalt was detected at a concentration below the SWSL, but above the NC 2L Standard, in sample from MW-7. Thallium was detected at concentrations below the SWSL, but above the NC 2L Standard, in samples from upgradient well MW-1RR and downgradient wells MW-6, MW-6D, MW-8, MW-9, and MW-11. Vanadium was detected at concentrations below the SWSL, but above the NC 2L Standard, in samples from downgradient wells MW-6, MW-6D, and MW-8. Because these concentrations of cobalt, thallium, and vanadium are below their respective SWSLs, no further action is warranted for these estimated detections. January 2018 11 Project No. 0939-668717 No NC Appendix I VOCs were detected at concentrations that exceeded the SWSL and NC 2L Standards in samples from groundwater monitoring wells during the September 2017 event at the closed Subtitle D landfill. As presented in Table 8, no NC Appendix I inorganic or organic constituents were detected above their applicable surface water standards in surface water monitoring points associated with the closed Subtitle D landfill during the September 2017 event. 4.1.3 Active Subtitle D Landfill As presented in Table 12, cobalt at MW-19 and silver at MW-22 were detected at concentrations that exceeded their respective SWSLs and GWPS during the September 2017 event at the active Subtitle D facility. The concentration of cobalt is below the proposed site-specific groundwater protection standard presented in the November 3, 2016, 14-day Notification and ASD and referenced in the May 15, 2017, 14-day Notification (Table 15). The ASD provided data to support that cobalt is naturally occurring and no further action is warranted. The original concentration of silver in the sample from MW-22 was considered suspect based on historical data and a verification sampling event was performed on December 20, 2017. Silver was detected at an estimated concentration below the SWSL and NC 2L Standard during the verification event. Therefore, the September 2017 concentration of silver in the sample from MW-22 was not confirmed and based on the verification result no further action is warranted. Cobalt was also detected at estimated concentrations below the SWSL, but above the GWPS, in the samples from MW-18 and MW-22. Thallium was detected at concentrations below the SWSL, but above the GWPS, in the samples from downgradient wells MW-14, MW-18, MW-19, and MW-22. Vanadium was detected at concentrations below the SWSL, but above the GWPS, in the samples from upgradient well MW-12 and downgradient wells MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-19, and MW-22. Because the concentrations of cobalt, thallium, and vanadium are below their respective SWSLs, no further action is warranted for these estimated concentrations. No NC Appendix I VOCs were detected above the SWSLs and applicable groundwater standards during the September 2017. As presented in Table 8, no NC Appendix I inorganic or organic constituents were detected at concentrations that exceeded the applicable surface water standards in samples from surface water monitoring points associated with the active Subtitle D landfill during the event. 5.0 CONCLUSIONS Due to the continued presence of VOCs above applicable groundwater standards in monitoring wells associated with the closed unlined landfill, the CCUC will continue to monitor the facility in accordance with the requirements of the Corrective Action Plan. Above-standard concentrations of NC Appendix I metals appear to be naturally occurring as reported in the November 3, 2016, 14-Day Notification and ASD and the May 15, 2017 14-Day Notification. The NC DEQ issued a response to the November 3, 2016, ASD on January 2018 12 Project No. 0939-668717 January 19, 2018, requesting additional information to be submitted within 120 days. The CCUC plans to prepare and submit and ASD addendum within the specified timeframe, but 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 2018. 6.0 REFERENCES Butler, J.R., and D.T. Secor, Jr., 1991. The Central Piedmont (Chapter 4) in J.W.
