(Waste Industries), Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the May 12 - 13, 2016, compliance monitoring event. Groundwater and surface water samples from the closed municipal solid waste landfill (MSW) were analyzed for North Carolina (NC) Appendix I constituents. Groundwater samples for the construction and demolition (C&D) facility were analyzed for NC Appendix I volatile organic constituents (VOCs), tetrahydrofuran, and RCRA metals as required in Title 15A NCAC 13B.0601 and Solid Waste Section (SWS) guidance documents. As presented, five inorganic constituents (arsenic, cobalt, copper, lead and zinc) were detected above their respective Solid Waste Section Limits (SWSLs) in samples from one or more downgradient MSW monitoring wells during the May 2016 monitoring event. Cobalt was detected above the SWS Groundwater Protection Standard (GPS) in samples from MW-10 and MW-15, as it has been during previous events. Arsenic was detected above the NC 2L Groundwater Standard at MW-19S and lead was detected above the NC 2L Standard during this event. As allowed by 15A NCAC 13B. 1632 (g) and (h), statistical analysis was performed to determine the source of above-standard concentrations of inorganic constituents detected above SWSLs in samples from downgradient monitoring points. The concentrations of cobalt were statistically determined to be below facility background concentrations and are considered to be naturally occurring; therefore, no further action is warranted. Cobalt and vanadium were also reported in one or more monitoring wells at estimated concentrations below the SWSLs, but above their respective groundwater standards in the samples collected at the closed MSW landfill. No further action is required because concentrations are estimated, and data are similar to historical and/or upgradient monitoring data. One inorganic constituent (mercury) was detected above the SWSL and groundwater standard in the sample collected from MW-17 at the closed C&D landfill during the May 2016 monitoring event. The concentration of mercury was statistically determined to be below facility background concentrations and are considered to be naturally occurring; therefore, no further action is warranted. No NC Appendix I organic constituents were detected in samples from the groundwater monitoring network at concentrations above the SWSLs. Also no NC Appendix I constituents were detected above SWSLs or applicable surface water standards during the May 2016 event. Leachate results were typical to historical results for this facility.

The Closed MSW Landfill facility is a Subtitle D facility and is monitored in accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B.1633. Groundwater at the closed C&D Landfill is monitored in accordance with Title 15A NCAC 13B.0601. The facility is located on the southern half of the Sampson County Disposal, LLC property and is comprised of one closed Subtitle D MSW disposal area and one closed C&D disposal area. Post-closure care for the facility is managed by Sampson County, LLC, a subsidiary of Waste Industries, Inc., under Permit No. 82-01 issued by the North Carolina (NC) Department of Environment and Natural Resources (DENR). The northern half of the landfill property is comprised of one active MSW landfill and one C&D landfill, which is covered under Permit No. 82-02. The results for that facility are submitted under separate cover. 1.1 Site Description and Background The location of the facility is shown on the inlay on Drawing 1. The Sampson County Landfill facility is located approximately 6.5 miles west of Clinton, North Carolina in Sampson County near the community of Snow Hill. Access to the site is from Roseboro Highway (N.C. Highway 24), which is located south of the site. The Bearskin Swamp is located along the eastern property boundary and drains to the southwest into Little Coharie Creek. The location of surface water features are shown on Drawing 1. Based on the topography as shown on Drawing 1, topographic surface elevations at the facility range from elevations of approximately 110 feet above mean sea level (AMSL) along the eastern portion of the facility to 275 feet AMSL in the central portion of the former MSW disposal area. The site is surrounded predominantly by wooded, agricultural or rural residential properties. Roseboro Highway (N.C. Highway 24) is located to the south of the site. The closed MSW and C&D facilities were formerly owned and operated by BFI/Allied Waste. The closed, unlined MSW and C&D disposal areas owned and maintained by Sampson County are located to the immediate south of the MSW permit 82-02 landfill. 1.2 Compliance Monitoring History Groundwater monitoring at the facility was initiated in October 1993. The facility’s approved MSW monitoring network is currently comprised of twelve monitoring wells, which monitor the uppermost aquifer beneath the facility. Monitoring wells MW-11, MW-14 and MW-14A are the facility’s three upgradient background wells. Wells MW-8, MW-9, MW-9A, MW-10, MW-10A, MW-12, MW-13, MW-15 July 2016 2 073-9603816.100 and MW-18 are crossgradient or downgradient compliance wells. Wells MW-16 and MW-17 are downgradient wells that monitor the closed C&D landfill. Wells MW-19S and MW-19D were installed in 2000 by G.N. Richardson and Associates (GNRA) as part of groundwater assessment activities; these two wells are not part of the approved compliance monitoring network. The wells were installed after volatile organic constituents (VOCs) were detected in some of the facility wells; these detections were attributed to the adjacent unlined County landfill. In addition to the groundwater monitoring points, the facility’s monitoring network includes two surface water sampling points, SW-1S (upstream) and SW-2S (downstream). Both surface water monitoring points are located along Bearskin Swamp on the eastern property boundary, which drains into Little Coharie Creek. Surface water sampling location SW-1S is located upstream of the landfill toward the northern end of the property and SW-2S is located downstream toward the southern end of the property where Highway 24 passes over Bearskin Swamp. These points are sampled in conjunction with the groundwater monitoring wells in accordance with the facility’s permit and approved Water Quality Monitoring Plan (WQMP). 1.3 Hydrogeologic Setting The facility is located in the western portion of the Coastal Plain Physiographic Province of North Carolina. The geologic units of this region are relatively young, dating from the Cretaceous Period to the present, and have been formed through transgression and regression of the Atlantic Ocean. The natural topography is flat to gently rolling with the upland surfaces gradually sloping downward in a southeasterly direction (S&ME 1992). The site is underlain by sands, silts, and clays of the Black Creek Formation, which consists of crossbedded layers of black to gray thinly-laminated clay and sand lenses of varied thickness and grain size. The formation is rich in mica, lignite, and iron sulfides. The Tuscaloosa formation underlies the Black Creek Formation and is comprised of gray to white sand and gravel with clay lenses (NCGS 1985). An undulating conformity forms the contact between the two formations with some interfingering of the two layers in the transition zone (NCGS 1960). The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of sands mixed with thin clay seams and larger seams of fine sand. Beneath the uppermost aquifer, a clay confining layer is present generally at a depth of approximately 20 - 25 feet below ground surface (BGS). The clay confining layer generally consists of black or dark gray silty clay, with thin seams of light gray fine sand (S&ME 1992). Groundwater occurs at depths varying from less than 2 feet to more than 25 feet BGS across the entire site. Depth-to-water measurements obtained during the May 2016 monitoring event, and summarized in Table 1, were used to prepare a groundwater surface contour map presented on Drawing 1. July 2016 3 073-9603816.100 Surface water and groundwater at the site generally flow to the northeast and east toward Bearskin Swamp, which is located along the eastern property boundary. The Bearskin Swamp flows slowly to the southwest and drains into Little Coharie Creek, located approximately two miles southwest of the facility. The groundwater surface contour map and interpreted flow directions are generally consistent with previously submitted interpretations for this facility. Based on the May 2016 groundwater surface contour map, the average hydraulic gradient in the shallow aquifer underlying the site as measured along the conceptual flow paths shown on the contour map was calculated to be approximately 0.018. Groundwater velocities were calculated using a hydraulic conductivity of 3.75 X 10-04 centimeters per second (cm/s), which is the average of the hydraulic conductivities calculated for the hydrogeologic units present at the facility. The estimated effective porosity of the shallow aquifer is also based on the average of the effective porosities for the hydrogeologic units are 0.186 (GNRA February 1999). 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 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 waste management unit is approximately 37 feet/year, which is generally consistent with previous estimates (Table 2). The range of groundwater flow is expected to vary depending on the hydrogeologic unit in which it occurs. 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 as part of the May 2016 sampling event are discussed in the following sections. 2.1 Visual Inspection Program In order to detect a potential release at the earliest possible time, the visual inspection program is used at the Sampson County Disposal, LLC Closed MSW and C&D Landfills by the sampling crews. 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 unit. During the May 2016 compliance July 2016 4 073-9603816.100 monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management areas by the sampling personnel. 2.2 Well Network and Groundwater Elevation Measurements The current compliance network of groundwater monitoring wells at the facility consists of 14 compliance wells and two groundwater assessment wells. Available monitoring well construction information for all site monitoring wells is summarized on Table 3 and the well locations are shown on Drawing 1. The well locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer underlying the facility, and to monitor for potential releases from the landfill unit. One upstream (SW-1S) and one downstream (SW-2S) surface water monitoring point are also monitored. Depth-to-water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. The respective groundwater elevations for this event are presented in Table 1. The historical water level data are also shown on this table. As presented, recent groundwater elevation data for the monitoring well network indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal variation from the long-term average limited to approximately 5 - 10 feet (plus or minus). The range in fluctuation appears to be greatest in the upgradient background well MW-14A, which is located in a groundwater recharge area. The range in fluctuation in the downgradient compliance wells, which are located near groundwater discharge areas, is much less, presumably due to the stabilizing effect of the hydraulic discharge boundary. 2.3 May 2016 Monitoring Event Personnel from Golder visited the facility on May 12 - 13, 2016, to purge and sample monitoring wells, to sample surface water monitoring points, and to sample the facility’s leachate collection system. Depth-to-water measurements were obtained from the network monitoring wells to the nearest 0.01 foot using an electronic water level indicator prior to purging the wells. The respective groundwater level elevations for this event are presented in Table 1. The historical water level data are also shown on this table. Most monitoring wells were purged and sampled using dedicated pumps and micropurge procedures. Measurements of pH, specific conductivity, temperature, turbidity, dissolved oxygen, and oxidation reduction potential were recorded on approximately 3-minute intervals, 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 the water, up to a maximum purge rate of 500 milliliters per minute. Purging was continued until stabilization was indicated by the water quality parameters. July 2016 5 073-9603816.100 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 dedicated pump discharge in the labeled, laboratory-supplied, pre-preserved sample containers after purging was completed based on stabilization of all water quality parameters, or removal of at least three well casing volumes for those wells that were bailed. 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 location, sampling equipment, sampling method, field observations, and water quality measurements. The surface water samples were collected directly from the stream, by lowering the sample containers into the stream flow with the bottles opening facing away from the current flow to prevent overflow and to minimize turbidity. Measurements of pH, specific conductivity, temperature, turbidity, dissolved oxygen, and oxygen reduction potential were measured directly from the stream and recorded during the collection of the surface water samples. The leachate sample was collected directly from the leachate piping manifold that empties into the secondary containment area for the leachate transportation vehicles. Measurements of pH, specific conductivity, temperature, and turbidity 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 method, field observations, and water quality measurements. 3.0 LABORATORY ANALYSIS PROGRAM The May 2016 groundwater, surface water, and leachate samples were submitted to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina under chain-of-custody control for analysis. As presented, groundwater and surface water samples at the facility were analyzed for NC Appendix I constituents and/or RCRA metals, as required. The leachate sample was analyzed for required parameters. The samples were received at the laboratory in good condition and properly preserved. 3.1 May 2016 Sampling Results Analytical results for the May 2016 groundwater, surface water, and leachate samples are summarized in Tables 4, 5, 6, 7, 8, 9, and 10 along with available historical data. The laboratory certificates-of-analysis, chain-of-custody form, and laboratory data reviews for this sampling event are included in Appendix B. July 2016 6 073-9603816.100 As presented, five inorganic constituents (arsenic, cobalt, copper, lead and zinc) were detected above their respective Solid Waste Section Limits (SWSL) in samples from one or more downgradient MSW monitoring wells during this monitoring event. No NC Appendix I VOCs were detected in samples from downgradient wells above the SWSLs during the May 2016 event. One inorganic constituent (mercury) was reported at a concentration above its SWSL in MW-17 during this event. No NC Appendix I VOCs were detected at concentrations above the SWSLs in samples from the C&D monitoring network during this event. There were no NC Appendix I inorganic or organic constituents detected above the SWSLs in the surface water samples. Also, leachate results were similar to previous monitoring events for this facility. 4.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the May 2016 groundwater sampling events. In addition to the field blank, a laboratory-prepared trip blank accompanied the volatile sample containers for the May 2016 sampling event to and from the laboratory. ENCO analyzed the field blank for NC Appendix I constituents and the trip blank for NC Appendix I volatile organic compounds. Reviews of the laboratory data were performed by Golder personnel and are included in Appendix B. Based on these reviews, copper was detected in the field blank at estimated concentrations during this event. Based on our review, the following copper concentrations are considered blank-qualified: MW-9, MW-9A, MW-11, MW-14, MW-14A, and MW-18 5.0 DATA EVALUATION The results of the data evaluations are presented in the following sections. 5.1 North Carolina Groundwater and Surface Water Standard Comparisons As presented in Table 4, arsenic at MW-19S, cobalt at MW-10 and MW-15, lead at MW-13, and mercury at MW-17 were detected at concentrations above their respective SWSLs and groundwater standards [i.e., NC 2L Standards or SWS Groundwater Protection Standards (GPS) groundwater samples] during the May 2016 sampling event. The concentrations of arsenic, cobalt, lead, and mercury were statistically evaluated as described below and determined to be representative of background conditions as described below and no further action is warranted. Cobalt and vanadium were also detected in samples from one or more upgradient and/or downgradient wells at estimated concentrations below the SWSL but above the GPS or NC 2L Standards; no further action is warranted as concentrations are estimated and similar to historical and background concentrations. No other exceedances of NC 2L Standards or SWS Groundwater Protection Standards were noted for this event. No constituents were detected in surface water samples above applicable surface water standards and SWSLs during this event. July 2016 7 073-9603816.100 5.2 Statistical Evaluations As presented, arsenic, cobalt, lead, and mercury were detected at concentrations above their respective SWSLs and applicable groundwater standards in samples from one or more downgradient monitoring wells during the May 2016 sampling event. To determine the source of these inorganic constituents, statistical analyses were performed as allowed by 15A NCAC 13B.1632 (g) and (h). The summary of statistical analysis and statistical worksheets are presented as Appendix C. Based on statistical evaluations, the concentrations of the aforementioned metals were not determined to be above facility background concentrations and were interpreted to represent naturally occurring concentrations. Therefore, no further action is warranted. 6.0 CONCLUSIONS Based on the May 2016 sampling data the Sampson County Disposal, LLC will continue monitoring this facility in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B.1633. The next scheduled compliance monitoring event is tentatively scheduled for November 2016. 7.0 REFERENCES GNRA (G.N.
