Trace levels of acetone were reported in surface water samples SW-1 and SW-2. The reported concentrations of acetone are well below the 15A NCAC 2B surface water quality standard. No other Appendix I VOCs were reported in either surface water sample. Low levels of various RCRA metals were reported in both surface water samples. However, the reported concentrations of metals in the surface water samples do not exceed the corresponding 15A NCAC 2B surface water quality standards. None of the reported concentrations of the RCRA metals detected in the groundwater samples collected from the site on October 3, 2016 exceed the corresponding 15A NCAC 2L .0202 groundwater quality standards. The results of analyses of the groundwater samples for Appendix I VOCs are generally consistent with the historical data presented in Table 3. Trace levels of acetone were reported in the samples collected from monitoring wells MW-3, MW-4, MW-6, and MW-8. The reported concentrations of acetone were well below the 15A NCAC 2L groundwater quality standard. It is also noted that acetone was detected in an associated blank sample at a similar concentration to those detected in the groundwater samples. PCE was reported in the groundwater sample collected from MW-8 (2.1 µg/L) at a concentration that exceeds the corresponding 15A NCAC 2L .0202 groundwater quality standards. No other Appendix I VOCs were reported in any of the groundwater samples. The results of a preliminary site assessment conducted in November 2010, as well as Phase 2, 3 and 4 site assessments conducted in April and May 2012, April 2013, and August 2014, respectively, indicate that the source of PCE in groundwater at MW-8 is unrelated to the Phase I/II landfill and is located in the vicinity of the maintenance shelter located north of MW-8. The results of the preliminary site assessment are reported in the January 2011 Preliminary Site Assessment Report, the results of the second phase of assessment are reported in the June 2012 Phase 2 Hydrogeologic and Groundwater Quality Assessment Report, the results of the third phase of assessment are reported in the May 2013 Phase 3 Hydrogeologic and Groundwater Quality Assessment Report, and the results of the Phase 4 site assessment are reported in the October 2014 Phase 4 Hydrogeologic and Groundwater Quality Assessment Report, all of which were previously submitted to the NCDENR Solid Waste Section. 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 C ell ● nautilusgeocon@gmail.com October 26, 2016 Ms. Elizabeth S. Werner, Hydrogeologist North Carolina Department of Environmental Quality Division of Waste Management Solid Waste Section 1646 Mail Service Center Raleigh, NC 27699-1646 RE: Report of Results Semi-Annual Groundwater and Surface Water Monitoring: October 2016 Central Carolina Tire Monofill Landfill Phase I/II Cameron, Harnett County, NC Permit # 43-04 Dear Ms. Werner: This report presents the results of semi-annual groundwater and surface water quality monitoring conducted at the landfill site referenced above (Figure 1) on October 3, 2016. The scope of work performed included sampling and laboratory analysis of groundwater samples from eight on-site monitoring wells (MW-2 through MW-9) and surface water samples from two on-site locations (SW-1 and SW-2). 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 October 3, 2016 as part of the site monitoring. Depths to groundwater were measured using an electronic water level probe that was thoroughly decontaminated between wells with a non-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 groundwater 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 October 3, 2016 are presented in Table 1. The depth to groundwater across the site, relative to the top of the PVC casing of – 2 – October 26, 2016 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com the monitoring wells, ranged from 2.50 feet at MW-2 to 15.63 feet at MW-9, which is consistent with the surface topography. A water-table elevation contour map that was developed based on the October 3, 2016 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 east-southeast, which is consistent with the surface topography and drainage features at the site. The average hydraulic gradient of the water table, based on the data depicted in Figure 3, ranges from approximately 0.037 ft./ft. in west-southwest portion of the site to approximately 0.017 ft./ft. in the east-northeast portion of the site. 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 October 3, 2016 for laboratory analysis to monitor the quality of groundwater and surface water at the site. 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. It is noted that monitoring well MW-9 serves as the upgradient, natural background well for the facility, and monitoring wells MW-2 through MW-7 serve as the downgradient monitoring wells. Monitoring well MW-8 is located immediately north of the landfill. Based on its location relative to the groundwater elevation contours, MW-8 is located hydraulically cross- gradient to the northern-most area of the landfill and hydraulically up gradient of most of the landfill area. All reusable sampling equipment was properly decontaminated between sampling locations with a non-phosphate soap and water wash, followed by multiple rinses with distilled water. New disposable nitrile or latex gloves were worn during all sampling activities. Disposable sampling equipment/material was discarded after each use. Prior to groundwater sampling, all monitoring wells were purged using pre-cleaned Teflon-lined disposable polyethylene tubing connected to a peristaltic pump under low flow conditions. 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 (see Groundwater Sampling Forms). Groundwater at the site is acidic to slightly acidic based on the pH values measured in the field (3.70 to 5.89). Specific – 3 – October 26, 2016 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com conductance values ranged from 58 (MW-7) to 202 (MW-6) µS/cm. Turbidity values ranged from 2.31 (MW-7) to 13.1 (MW-2) nephelometric turbidity units (NTUs). Surface water samples were collected from locations SW-1 and SW-2. The sampling locations are depicted in Figure 2. SW-1 is located approximately 140-feet south-southeast of the south- central sedimentation pond and within the drainage feature that parallels the southern limits of scrap tire disposal within the Phase I/II landfill. SW-2 is located approximately 250-feet south- southeast of the southeastern sedimentation pond and within the primary drainage feature that parallels the eastern limits of the Phase I/II landfill. The surface water samples from SW-1 and SW-2 were collected 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 on October 3, 2016 are presented in Table 2. Summarized historical groundwater and surface water quality data for the site are presented in Table 3. Copies of the original laboratory reports are included in Appendix B. The laboratory analytical results for surface water samples SW-1 and SW-2 indicate that trace levels of acetone were reported in samples SW-1 and SW-2 (6.6 µg/L and 5.6 µg/L, respectively). The reported concentrations of acetone were well below the 15A NCAC 2B surface water quality standard. No other Appendix I VOCs were reported in either sample. Low levels of various RCRA metals were reported in both surface water samples. However, the reported concentrations of metals in the surface water samples do not exceed the corresponding 15A NCAC 2B surface water quality standards. The laboratory analytical results for the groundwater samples collected from the site monitoring wells on October 3, 2016 indicate that trace levels of acetone were reported in the samples collected from monitoring wells MW-3, MW-4, MW-6, and MW-8. The reported concentrations of acetone were well below the 15A NCAC 2L groundwater quality standard. It is also noted that acetone was detected in an associated blank sample at a similar concentration to those detected in the groundwater samples. Tetrachloroethene (PCE) was reported at a concentration of 2.1 µg/L in the groundwater sample collected from MW-8, which exceeds the 15A NCAC 2L .0202 groundwater quality standard of 0.70 µg/L. It is noted that the results of a preliminary site assessment conducted in November 2010, as well as Phase 2, 3 and 4 site assessments conducted in April and May 2012, April 2013, and August 2014, respectively, indicate that the source of PCE in groundwater at MW-8 is unrelated to the Phase I/II landfill and is located in the vicinity of the maintenance shelter north of MW-8. No other Appendix I VOCs were reported in any of the groundwater samples. – 4 – October 26, 2016 11112 BRANDING IRON PLACE, WENDELL, NC 27591 919-366-3663 Office ● 919-995-0363 Cell ● nautilusgeocon@gmail.com The results of the metals analyses of the groundwater samples indicate that arsenic was reported in three of the samples, barium and lead were reported in all of the samples, cadmium was reported in seven of the samples, chromium was reported in three of the samples, mercury was not reported in any of the samples, selenium was reported in six of the groundwater samples, and silver was reported in three of the samples. None of the reported concentrations of the metals detected in any of the groundwater samples exceed the corresponding 15A NCAC 2L .0202 groundwater quality standards. 3.0 CONCLUSIONS AND RECOMMENDATIONS The results of the October 3, 2016 groundwater and surface water quality monitoring conducted at the Central Carolina Tire Monofill Landfill Phase I/II are generally consistent with the results of previous monitoring conducted at the site.
