This monitoring event satisfies requirements of the detection monitoring program under Solid Waste Permit No. 92-26 and Solid Waste Regulations 15A NCAC 13B .0544. The following report summarizes sampling procedures, field and laboratory results and groundwater characterization as required by North Carolina Solid Waste Regulations. The North Carolina Department of Environmental Quality (NCDEQ) Environmental Monitoring Reporting Form is included with the document. In addition to groundwater and surface water monitoring, 11 landfill gas monitoring wells (LG-1 through LG-11) were monitored in March and June 2015 to satisfy requirements in the facility’s Solid Waste Permit. In June 2014, landfill gas well LG-8 was abandoned and replaced with LG- 8R by Garrett & Moore. LG-8R is located in close proximity to groundwater monitoring well MW-1A. Landfill gas monitoring results are also summarized herein. 2.0 Field Methods 2.1 Groundwater and Surface Water Monitoring Groundwater gauging and sampling was completed at eight (8) monitoring wells (MW-1A, MW- 3A, MW-4S, MW-4D, MW-5, MW-6, MW-7 and MW-8). Surface water sampling was completed at three (3) established locations (SW-1, SW-2, and SW-3). Groundwater and surface water monitoring locations are shown on Figure 1. During the monitoring event, the wells were inspected for signs of damage or unusual conditions. The wells were found to be in good condition and free of obstructions. Low-flow (micro-purge) sampling procedures were used for well purging and groundwater sampling during the June 2015 sampling event, except for well MW-1A. The sample collection process was consistent with industry standard practices. The monitoring wells were gauged with a decontaminated electric water level meter to determine the depth to groundwater and then micro-purged at a rate of approximately 100 to 300 milliliters per minute using new disposable tubing attached to a peristaltic pump. A disposable bailer was used to purge and sample well MW-1A because the depth to water exceeded the maximum depth capability of the peristaltic pump. Well MW-1A was purged until essentially dry. A summary of well construction, depth to groundwater and groundwater elevation data is provided in Table 1. Field parameters consisting of temperature, pH, specific conductivity, turbidity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) were measured at regular (i.e., approximate three (3) to five (5) minute) intervals using a YSI Model 6920 Multi-parameter meter and flow-through cell during micro-purging until parameters stabilized to within approximately 10%. Field parameters were measured at well MW-1A following the removal of each well volume of water until parameters stabilized. 4 Groundwater samples were collected in laboratory containers provided by Environmental Conservation Laboratories (ENCO, a North Carolina certified laboratory) for Appendix I volatile organic compounds (VOCs) by United States Environmental Protection Agency (EPA) Method 8260B, Appendix I metals by EPA Methods 6010C/6020A, mercury by EPA Method 7470A, chloride and sulfate by EPA Method 300.0, total alkalinity by EPA Method 310.2 and total dissolved solids (TDS) by SM 2540C. Surface water samples were submitted to ENCO for Appendix I VOCs and 15 metals. Samples were transported to the laboratory under chain-of- custody protocols and analyzed at or below the specified NCDEQ Solid Waste Section Limits (SWSLs). Sample collection record sheets are provided in Appendix A. 2.2 Landfill Gas Monitoring Eight (8) landfill gas monitoring wells (LG-1 through LG-8) were installed at the site in June 2011 as presented in the Spring 2011 Groundwater Monitoring Report. Three (3) additional landfill gas monitoring wells (LG-9, LG-10, and LG-11) were installed at the site in October 2012 as sentinel downgradient wells for LG-3 and LG-4 that had registered elevated methane levels. In June 2014, landfill gas well LG-8 was abandoned and replaced with LG-8R. Landfill gas monitoring well locations are shown on Figure 1. Landfill gas quarterly monitoring events were conducted on March 31, 2015, and June 23, 2015, during this reporting period. Percent lower explosive limit (% LEL) measurements and other applicable parameters (i.e., % methane by volume, % oxygen and % carbon dioxide) were recorded at the landfill gas monitoring wells using a laboratory calibrated Landtec GEM 2000 instrument. 3.0 Field and Analytical Results 3.1 Groundwater Results As noted in Section 2 above, field parameters including temperature, pH, specific conductivity, turbidity, DO and ORP were measured and recorded during well purging activities. Stabilized field parameter measurements are provided in Table 2 along with the approximate total volume of water purged. Groundwater analytical results indicated that no VOCs were detected above their respective 15A NCAC 2L Standard (North Carolina Groundwater Quality Standard, or Interim Maximum Allowable Concentration, hereinafter referred to as the 2L Standard). Several metals were detected above their respective 2L standard as follows: Beryllium: MW-1A. Cobalt: MW-6. Note: (MW-1A, MW-4S, MW-7 and MW-8 had detections above 2L but were estimated concentrations (“J” flagged) indicating the reported concentration was between the method detection limit (MDL) and the method reporting limit (MRL). Iron: MW-1A, MW-4S, MW-6 and MW-8. 5 Lead: MW-1A. Manganese: MW-1A, MW-4S, MW-4D, MW-6 and MW-8. Thallium: MW-1A and MW-7 (both detections were estimated values (“J” flagged). Vanadium: MW-1A and MW-8 (both detections were estimated values (“J” flagged). No additional target compounds were detected in the groundwater samples that exceeded the 2L Standards. No 2L Standards are established for total alkalinity. Groundwater analytical results are summarized in Table 3 and the laboratory analytical report is provided in Appendix B. For quality assurance/quality control, a trip blank accompanied the samples and a duplicate sample (Duplicate) was collected at well MW-3A. The results compared favorably with the MW- 3A results. The trip blank did not contain any compounds above the laboratory MDL. 3.2 Surface Water Results Surface water analytical results indicated that no VOCs were detected in the samples collected above their respective 15A NCAC 2B Surface Water Standard (hereinafter referred to as the 2B Standards, or National Criteria per EPA). For metals, only Vanadium was detected, at estimated concentrations (“J” flagged), in the samples collected at SW-1 and SW-3. No 2B Standard has been established for Vanadium and therefore, by default, a detected concentration is considered above the standard. Surface water analytical results are summarized in Table 3 and the laboratory analytical report is provided in Appendix B. 3.3 Landfill Gas Results As noted above, quarterly landfill gas monitoring events were conducted on March 31, 2015, and June 23, 2015, at 11 landfill gas wells and the scale house during the reporting period. Wells LG-3 and LG-4 exhibited greater than 100% of the lower explosive limit (LEL) during the reporting period (i.e., 252% LEL at LG-3 in June, and 556% LEL and 656% LEL in March and June, respectively, at LG-4). Percent LEL measurements recorded at downgradient sentinel wells LG-9, LG-10, and LG-11 exhibited 0% LEL during the reporting period. Replacement well LG-8R exhibited 15% LEL during the reporting period. Landfill Gas Monitoring Data Forms for the reporting period are provided in Appendix C. Historical landfill gas monitoring data are summarized in Table 4. 4.0 Groundwater Characterization A water table contour map was prepared from the well gauging data collected on June 22, 2015, as shown on Figure 1. According to the figure, shallow groundwater continues to migrate generally toward the southwest as historically observed. The addition of the data point at well MW-8 indicates shallow groundwater flow in the central portion of the site is generally toward the south and the intermittent stream on-site. 6 The horizontal groundwater velocity was estimated from a previously calculated hydraulic conductivity value at well MW-5 using the equation V = KI/n where: V = estimated horizontal velocity K = calculated hydraulic conductivity from slug testing I = estimated shallow hydraulic gradient n = estimated effective porosity The estimated shallow groundwater velocity ranged from 0.016 feet/day south of the intermittent stream to 0.068 feet/day north of the intermittent stream as shown on Figure 1 and Table 5. 5.0 Summary and Conclusions No VOCs were detected in groundwater or surface water above their respective 2L or 2B standards. Seven (7) inorganic analytes (beryllium, cobalt, iron, lead, manganese, thallium and vanadium) were detected at concentrations at or above the 2L Standard in groundwater at the site as follows:  Beryllium – MW-1A;  Cobalt – MW-6, (MW-1A, MW-4S, MW-7 and MW-8 at estimated values);  Iron – MW-1A, MW-4S, MW-6 and MW-8;  Lead – MW-1A;  Manganese – MW-1A, MW-4S, MW-4D, MW-6 and MW-8;  Thallium – (MW-1A and MW-7 at estimated values);  Vanadium – (MW-1A and MW-8 at estimated values). Vanadium was detected in surface water samples SW-1 and SW-3. A 2B Standard has not been established for Vanadium and therefore; any detected concentration is considered to be above the standard. Vanadium has historically been detected at these two surface water locations. As anticipated with the use of low-flow sampling techniques, the turbidity values during this sampling event were zero (0) Nephelometric Turbidity Units (NTUs) for the seven (7) low-flow wells, thereby minimizing suspended solids in the samples. The turbidity value for well MW-1A that was purged and sampled with a bailer was 100 NTUs. The data supports the historical conclusion that the metals detected at the site are naturally occurring. Elevated % LEL readings continue to be observed at wells LG-3 and LG-4. The % LEL at LG-4 appears to be generally stable since November 2012 (i.e., fluctuating between 468% and 806%). The % LEL at LG-3 increased to above 100% in December 2014 and again in June 2015 after being at or below 54% since January 2013. The downgradient sentinel landfill gas wells for LG-3 and LG-4 continue to indicate that off-site migration of landfill gas is not occurring. Percent LEL measurements obtained from downgradient wells LG-9, LG-10, and LG- 11 remained at zero during the reporting period. 7 Quarterly landfill gas monitoring will continue at the site with the next two (2) events scheduled for September and December 2015. Semi-annual groundwater monitoring will continue at the site with the next event scheduled for December 2015.
