A trace concentration of acetone was detected in the sample collected from sampling location SW-4 (8.0 µg/L, estimated). No other Appendix I VOCs were detected in either surface water sample. Low levels of arsenic, barium, cadmium, chromium and lead were reported in both of the surface water samples. None of the reported concentrations of these metals in the surface water samples exceed the corresponding 15A NCAC 2B surface water quality standards or the 15A NCAC 2L .0202 groundwater quality standards. Trace levels of cis-1,2-dichloroethene, methylene chloride, tetrahydrofuran and trichlorofluoromethane were reported in the groundwater sample collected from monitoring well MW-4, a trace level of trichlorofluoromethane was reported in the groundwater sample collected monitoring well MW-5, a trace level of methylene chloride was reported in the groundwater sample collected from monitoring well MW-6R. A trace concentration of chloroform was reported in the groundwater sample collected from monitoring well MW-7, and trace concentrations of bromodichloromethane, chloroform, and dibromochloromethane were reported in the groundwater sample collected from monitoring well MW-8. The concentrations of bromodichloromethane and dibromochloromethane reported in the groundwater sample collected from MW-8 exceed the corresponding 15A NCAC 2L groundwater quality standards. It is noted that all of the VOCs reported in the groundwater samples collected from MW-7 and MW-8 are trihalomethanes (THMs), which are commonly found in potable water from public water supplies treated by chlorination. Potable water used during drilling of monitoring wells MW-7 and MW-8 was from the public water supply available at the landfill facility. Therefore, it is concluded that the THMs detected in the groundwater samples collected MW-7 and MW-8 were from the potable water used during drilling. It is anticipated that the levels of THMs in groundwater at monitoring wells MW-7 and MW-8 will diminish over time. – 2 – December 18, 2017 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com The reported concentrations of lead in the sample from MW-5, cadmium, chromium and mercury in the sample from MW-6R and chromium in the sample from MW-8 exceed the corresponding 15A NCAC 2L groundwater quality standards. It is likely that the exceedances of the groundwater quality standards of the metals in the groundwater samples from MW-5, MW-6R and MW-8 are due to the elevated turbidity of the groundwater samples collected from these wells. It is anticipated that the turbidity of groundwater collected from these wells will improve when groundwater levels return to more typical levels as precipitation levels return to a more normal range. 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com December 18, 2017 Ms. Jaclynne Drummond North Carolina Department of Environmental Quality Division of Waste Management Solid Waste Section 2090 US 70 Highway Swannanoa, NC 28778 RE: Report of Results Semi-Annual Groundwater and Surface Water Monitoring: November 2017 Nash County C&D Landfill Nashville, Nash County, NC Permit # 64-03 Dear Ms. Drummond: This report presents the results of semi-annual groundwater and surface water quality monitoring conducted at the C&D landfill site referenced above (Figure 1) in November 2017. The scope of work performed included sampling and laboratory analysis of groundwater samples from eight on-site monitoring wells (MW-1 through MW-6R, MW-7 and MW-8) and surface water samples from two on-site locations (SW-3 and SW-4). Due to Phase 4 landfill expansion, existing Type II monitoring well MW-6 was abandoned in August 2017 and existing piezometer P-21 was converted to a permanent monitoring well as a replacement (designated MW-6R). In addition, two new Type II groundwater monitoring wells (MW-7 and MW-8) were installed hydraulically down gradient of Phase 4 to expand the existing groundwater monitoring well network in August 2017. The groundwater and surface water samples were collected in accordance with the NCDEQ, Division of Waste Management (DWM), Solid Waste Section (SWS) Groundwater Monitoring Guidance Document and the facility Water Quality Monitoring Plan. The sampling and data collection methods, as well as the current and historical results of field and laboratory testing of the water samples, are presented in the following sections. 1.0 POTENTIOMETRIC PATTERN AND GROUNDWATER FLOW Groundwater levels were gauged in the site groundwater monitoring wells on November 16, 2017 as part of the site monitoring. Depths to groundwater were measured using an electronic water-level meter that was thoroughly decontaminated between wells with a non- – 2 – December 18, 2017 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com phosphate soap and water wash followed in order by multiple rinses with distilled water, an isopropyl alcohol rinse, and multiple distilled water rinses. Depth-to-water measurements were made after the wells were opened for a sufficient period of time to allow water levels to equilibrate with atmospheric pressure. The locations of the site monitoring wells are depicted in Figure 2. Groundwater elevation data collected at the monitoring wells on November 16, 2017 are presented in Table 1. The depth to groundwater across the site measured relative to the top of the PVC casing of the Type II groundwater-monitoring wells on November 16, 2017 ranged from 13.02 feet (MW-7) to 44.08 feet (MW-5), which is consistent with the surface topography. It is noted, however, that the depths to groundwater measured in November 2017 were significantly lower (approximately 3 to 5 feet at most wells) than those measured in May 2017. A water-table elevation contour map that was developed based on the November 16, 2017 groundwater-gauging data for the Type II monitoring wells is presented as Figure 3. The pattern of the water-table contours indicates that the horizontal component of shallow groundwater flow at the site is generally to the northeast, which is consistent with the surface topography and drainage features at the site. The delineated direction of shallow groundwater flow is also consistent with previous estimates of groundwater flow direction at the site. The hydraulic gradient of the water table, based on the data depicted in Figure 3, is approximately 0.016 ft./ft. 2.0 RESULTS OF GROUNDWATER AND SURFACE WATER SAMPLING AND ANALYSIS Groundwater samples were collected from the site monitoring wells and surface water samples were collected from two on-site locations on November 16 and 17, 2017 for laboratory analysis to monitor the quality of groundwater and surface water at the site. It is noted that monitoring well MW-1 serves as the up gradient, background well for the facility, and monitoring wells MW-2 through MW-6R, MW-7 and MW-8 serve as the down gradient monitoring wells. The groundwater and surface water samples were collected and handled in accordance with the sampling protocols included in the site Water Quality Monitoring Plan as well as the SWS Groundwater Monitoring Guidance Document. Prior to groundwater sampling, monitoring well MW-7 was purged of stagnant water using pre-cleaned Teflon- lined disposable polyethylene tubing connected to a peristaltic pump under low flow (≤ 200 ml/min) conditions. Monitoring wells MW-1 through MW-6R and MW-8 were purged and sampled using disposable, bottom-loading PVC bailers due to the depth to groundwater. Surface water samples were collected directly into sample containers by direct submersion in the stream. All reusable sampling equipment was properly decontaminated between sampling locations with a non-phosphate soap and water wash, followed by multiple rinses – 3 – December 18, 2017 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com with distilled water. New disposable nitrile or latex gloves were worn during all sampling activities. Disposable sampling equipment/material (e.g., disposable bailers, gloves, etc.) was discarded after each use. During purging, measurements were made in the field of the pH, temperature, specific conductance and turbidity of the groundwater collected from the monitoring wells, in accordance with SWS requirements. The results of the field analyses of these parameters are presented in Table 1. Copies of Groundwater Sampling Forms containing pertinent information recorded in the field during purging and sampling at each groundwater monitoring well are presented in Appendix A. The results of the field-measured water- quality parameters indicate that the values measured in groundwater collected from the site monitoring wells were generally within the applicable stabilization criteria with the exception of turbidity at all monitoring wells except MW-1 and MW-7. Elevated turbidity at the remaining monitoring wells (ranging from 20.9 to 28.9 NTUs) is likely due to low groundwater levels at those locations resulting from a prolonged dry period in the area of the landfill. Groundwater at the site is acidic based on the pH values measured in the field (4.70 to 5.57). Specific conductance values ranged from 40 (MW-3 and MW-5) to 77 (MW- 4) µS/cm and turbidity values ranged from 8.2 (MW-7) to 28.9 (MW-3 and MW-8) NTUs. It is noted that groundwater in all monitoring wells purged with disposable bailers was allowed to recover and settle for approximately 24 hours before the final turbidity of the groundwater samples was measured and the samples collected. Surface water samples were collected from two locations at the site (SW-3 and SW-4). The sampling locations are depicted in Figure 2. SW-3 is located approximately 1,200-feet southeast (downstream) of the C&D Landfill along Pig Basket Creek. SW-4 is located upstream where Pig Basket Creek runs under a bridge at State Road 1411. All surface water samples were collected directly into sample containers by direct submersion in the stream in accordance with the protocol presented in the SWS Groundwater Monitoring Guidance Document. All groundwater and surface water samples were analyzed at a North Carolina-certified laboratory for Appendix I volatile organic compounds (VOCs) by SW 846 Method 8260 and the 8 RCRA metals by EPA 6000/7000 series methods. Summarized results of laboratory analyses for groundwater and surface water samples collected from the site in November 2017 are presented in Table 2. Summarized historical groundwater and surface water quality data (from 2008 to present) for the site are presented in Table 3. Copies of the original laboratory reports are included in Appendix B. – 4 – December 18, 2017 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com The laboratory analytical results for the surface water samples collected from the site in November 2017 indicate that a trace concentration of acetone was detected in the sample collected from sampling location SW-4 (8.0 µg/L, estimated).

None of the reported concentrations of these metals in the surface water samples exceed the corresponding 15A NCAC 2B surface water quality standards or the 15A NCAC 2L .0202 groundwater quality standards. The laboratory analytical results for the groundwater samples collected from the site monitoring wells in November 2017 indicate that trace levels of cis-1,2-dichloroethene, methylene chloride, tetrahydrofuran and trichlorofluoromethane were reported in the groundwater sample collected from monitoring well MW-4, a trace level of trichlorofluoromethane was reported in the groundwater sample collected monitoring well MW-5, a trace level of methylene chloride was reported in the groundwater sample collected from monitoring well MW-6R. A trace concentration of chloroform was reported in the groundwater sample collected from monitoring well MW-7, and trace concentrations of bromodichloromethane, chloroform, and dibromochloromethane were reported in the groundwater sample collected from monitoring well MW-8. The concentrations of bromodichloromethane and dibromochloromethane reported in the groundwater sample collected from MW-8 exceed the corresponding 15A NCAC 2L groundwater quality standards.

No other Appendix I VOCs were reported in any of the groundwater samples. The results of the metals analyses of the groundwater samples indicate that arsenic, barium, chromium and lead were detected in all of the samples, cadmium was detected in seven of the samples, mercury was reported in two of the samples, selenium was detected in four of the samples and silver was reported in one of the samples. The reported concentrations of lead in the sample from MW-5, cadmium, chromium and mercury in the sample from MW-6R and chromium in the sample from MW-8 exceed the corresponding – 5 – December 18, 2017 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com 15A NCAC 2L groundwater quality standards. It is likely that the exceedances of the groundwater quality standards of the metals in the groundwater samples from MW-5, MW- 6R and MW-8 are due to the elevated turbidity of the groundwater samples collected from these wells. It is anticipated that the turbidity of groundwater collected from these wells will improve when groundwater levels return to more typical levels as precipitation levels return to a more normal range. None of the reported concentrations of RCRA metals in the groundwater samples from the remaining monitoring wells exceed the corresponding 15A NCAC 2L .0202 groundwater quality standards. 3.0 CONCLUSIONS AND RECOMMENDATIONS The results of the November 2017 groundwater and surface water quality monitoring conducted at the Nash County C&D Landfill are generally consistent with the results of previous monitoring conducted at the site.
