One monitoring well (8103-MW-12) was dry on the date that samples were collected. Six of the wells (8103-MW-2, 8103-MW-4, 8103- MW-6, 8103-MW-7, 8103-MW-8, and 8103-MW-9) comprise the Subtitle D groundwater monitoring system for the municipal solid waste disposal area of the landfill. Six monitoring wells comprising two well nests (8103-MW-10A, 8103-MW-10B, 8103-MW-10C, 8103-MW-10D, 8103- MW-11A, and 8103-MW-11B) were installed in August 1998 to provide additional data on the nature and extent of the contaminant plume emanating from the disposal area. 8103-MW-10A has an extremely slow recharge rate and is not used as a sampling location. Five monitoring wells (8103-MW-3, 8103-MW-12, 8103-MW-13, 8103-MW-14, and 8103-MW-15) comprise the groundwater monitoring system for the construction and demolition (C&D) and yard waste disposal areas and the transfer station facility. 8103-MW-2 provides the upgradient groundwater data for the facility’s water quality monitoring. All sampling was conducted in accordance with North Carolina Solid Waste Management Guidelines. Samples from 8103-MW-2, 8103-MW-3, 8103-MW-4, 8103-MW-6, 8103-MW-7, 8103-MW-8, 8103-MW-9, 8103-MW-10B, 8103-MW-10C, 8103-MW-10D, 8103-MW-11A, 8103-MW-11B, 8103-MW-13, 8103-MW-14, and 8103-MW-15 were submitted to a North Carolina certified laboratory for analysis using the Federal Appendix I list of constituents for detection monitoring. The Appendix I detection monitoring constituent list is a subset of the Federal Appendix II assessment monitoring constituent list. Samples from 8103-MW-4, 8103-MW-6, 8103-MW-7, 8103-MW-8, 8103-MW-9, 8103-MW-10B, 8103-MW-10C, 8103-MW-10D, 8103-MW-11A, and 8103-MW-11B were also analyzed for triggered Federal Appendix II assessment monitoring Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 1 constituents. In this report, the term "triggered Appendix II constituent" refers to any Appendix II constituent not included in the Appendix I list that was detected above the quantitation limit established by the Solid Waste Section during a previous sampling event. Samples from surface water locations 8103-SW-2, 8103-SW-3, 8103-SW-4, and 8103-SW-5 were analyzed for Federal Appendix I detection monitoring constituents. In addition to Appendix I and triggered Appendix II parameters, samples from 8103-MW-2, 8103- MW-4, 8103-MW-6, 8103-MW-8, 8103-MW-9, 8103-MW-10D, and 8103-MW-11A were analyzed for the MNA parameters set forth in the NC Solid Waste Section CAP approval letter dated August 17, 2007. The results of the laboratory analyses and field tests for the MNA parameters are discussed in Section 5.3. In addition to Appendix I parameters, samples from 8103-MW-2, 8103-MW-3, 8103-MW-13, 8103-MW-14, and 8103-MW-15 were analyzed for the C&D parameters set forth in the NC Solid Waste Section approved monitoring plan. Surface water samples 8103-SW-2, 8103-SW-3, 8103- SW-4, and 8103-SW-5 were also analyzed for the C&D parameters. The results of the laboratory analyses for the C&D parameters are discussed in Section 5.4. Results from the fifteen monitoring wells sampled indicate that four Appendix I inorganic constituents (chromium in 8103-MW-2, 8103-MW-7, 8103-MW-10B, 8103-MW-10C, and 8103- MW-11B; cobalt in 8103-MW-2, 8103-MW-3, 8103-MW-4, 8103-MW-6, 8103-MW-7, 8103-MW- 10B, 8103-MW-10C, 8103-MW-10D, 8103-MW-11A, 8103-MW-11B, and 8103-MW-13; thallium in 8103-MW-6, 8103-MW-13, 8103-MW-14, and 8103-MW-15; and vanadium in 8103-MW-2, 8103-MW-3, 8103-MW-4, 8103-MW-6, 8103-MW-7, 8103-MW-8, 8103-MW-10B, 8103-MW- 10C, 8103-MW-11A, 8103-MW-11B, 8103-MW-13, 8103-MW-14, and 8103-MW-15) were present in concentrations exceeding the 15A NCAC 2L Standards for Class GA Groundwater (2L) or NC Groundwater Protection (NCGP) Standards. Ten Appendix I inorganic constituents (arsenic, barium, beryllium, cadmium, chromium, copper, lead, nickel, selenium, and zinc) were detected in one or more of the monitoring well samples at concentrations at or above the Method Detection Limits (MDLs), but below the 2L or NCGP Standards.

The surface water samples were collected from creeks along the northern, western, and southern perimeters of the landfill property. 2.0 INTRODUCTION Central Sanitary Landfill is a Solid Waste Management Facility (SWMF) located off of Business Highway 74 at the south end of Laurel Hill Drive south of Rutherfordton in Rutherford County, North Carolina. Figure 1 is a map showing the site location. Groundwater and surface water sampling locations are shown on Figure 2. Scarlett Geophysical Consulting, P.C. (SGC) was contracted by Rutherford County to conduct sampling efforts to satisfy the following groundwater monitoring requirements: • 2015 semi-annual C&D water quality monitoring • 2015 semi-annual Appendix I detection monitoring • 2015 semi-annual Appendix II (triggered constituents only) assessment monitoring • 2015 semi-annual MNA monitoring Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 4 To complete the semi-annual C&D water quality monitoring requirement, samples from 8103-MW- 2, 8103-MW-3, 8103-MW-13, 8103-MW-14, 8103-MW-15, 8103-SW-2, 8103-SW-3, 8103-SW-4, and 8103-SW-5 were analyzed for the Appendix I constituent list and the C&D parameters set forth in the NC Solid Waste approved monitoring plan plus aluminum. 8103-MW-12 was dry on the date that samples were collected. To complete the semi-annual Appendix I and triggered Appendix II monitoring requirements, samples from 8103-MW-2, 8103-SW-2, 8103-SW-3, 8103-SW-4, and 8103-SW-5 were analyzed for Appendix I inorganics and volatile organics and samples from 8103-MW-4, 8103-MW-6, 8103- MW-7, 8103-MW-8, and 8103-MW-9, 8103-MW-10B, 8103-MW-10C, 8103-MW-10D, 8103- MW-11A, and 8103-MW-11B were analyzed for the full list of Appendix I constituents and triggered Appendix II constituents 1,3-dichlorobenzene; 1,3-dichloropropane; dichlorodifluoromethane; 4,4'-DDD; 4,4'-DDT; alpha-BHC; beta-BHC; delta-BHC; endrin; gamma-BHC (Lindane); and mercury. Monitoring wells 8103-MW-6, 8103-MW-7, 8103-MW-8, and 8103-MW-9 were installed in November 1994 and March 1995 after three of the Appendix I baseline sampling rounds had been completed. The March 1995 sampling event was the first in which they were included. Monitoring wells 8103-MW-10A, 8103-MW-10B, 8103-MW-10C, 8103-MW-10D, 8103-MW- 11A, and 8103-MW-11B were installed in August-September 1998 and were first included in the September 1998 sampling event. 8103-MW-10A was installed to provide deep groundwater samples, and 8103-MW-10D was installed to provide water level data. 8103-MW-10A has a very low recharge rate (less than 0.03 gallons over 24 hours); therefore, 8103-MW-10D has been designated the deep sample well. Monitoring wells 8103-MW-12 and 8103-MW-13 were installed in June 2002 and May 2001 to monitor the C&D waste disposal area of the landfill. 8103-MW-12 and 8103-MW-13 were first sampled in June 2002. Monitoring wells 8103-MW-14 and 8103-MW- 15 were installed in February 2008 to supplement the C&D area monitoring, and were first sampled in May 2008. Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 5 To complete the semi-annual MNA water quality monitoring requirement, samples from 8103- MW-2, 8103-MW-4, 8103-MW-6, 8103-MW-8, 8103-MW-9, 8103-MW-10D, and 8103-MW-11A were analyzed for the MNA parameters set forth in the NC Solid Waste Section CAP. 3.0 SCOPE OF WORK To fulfill the groundwater monitoring requirements, SGC completed the following tasks: • Sampled fifteen monitoring wells and four surface water locations at the Central Sanitary Landfill SWMF. 8103-MW-12 was dry on the date that samples were collected. • Obtained field values for pH, temperature, and conductivity at each sample location • Obtained field values for ORP, DO, and turbidity at the MNA sample locations • Analyzed the appropriate samples for Appendix I and triggered Appendix II constituents by a North Carolina certified laboratory using State approved methods • Analyzed the appropriate samples for MNA parameters • Analyzed the appropriate samples for C&D parameters • Determined groundwater flow rates and directions at the monitoring well locations • Prepared a report for the State 4.0 METHODS EMPLOYED 4.1 Monitoring Well Sampling Groundwater monitoring well sampling took place September 28-October 7, 2015. The monitoring well locations are shown on Figure 2. A representative from SGC opened each well and measured the static water level from the top of the PVC casing. The volume of water in the well was calculated. These data are summarized in Table 1. The wells were purged until a minimum of three well volumes was removed, the well was purged dry, or the indicator field parameters were stabilized (for the wells purged using pneumatic pumps). Following purging, groundwater samples were collected and pH, temperature, and conductivity were measured and recorded on the groundwater sampling field data sheets. Field measurements for oxidation-reduction potential Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 6 (ORP), dissolved oxygen (DO), and turbidity were obtained from the designated MNA wells. A groundwater sampling field data sheet for each well is included in Appendix A. Table 2 summarizes the results of the field data. Samples from 8103-MW-3, 8103-MW-4, 8103-MW-10D, and 8103-MW-11A were collected using the dedicated pumps installed in each well. Samples from 8103-MW-2, 8103-MW-6, 8103-MW-8, and 8103-MW-9 were collected using a properly decontaminated pneumatic pump and dedicated tubing. Samples from 8103-MW-7, 8103-MW-10B, 8103-MW-10C, 8103-MW-11B, 8103-MW- 13, 8103-MW-14, and 8103-MW-15 were collected using properly decontaminated teflon bailers. Immediately upon collection, each sample was placed in laboratory supplied glassware, packed on ice, and placed under chain-of-custody. The sampling technician wore new latex gloves, which were changed between wells and used separate bailers at each of the bailed wells to minimize the possibility of cross contamination. New bailer cord was used for each purging/sampling event where a pneumatic pump was not available. The surface water samples were collected by immersing laboratory supplied containers in the water to be sampled. After collection, each sample was packed on ice and placed under chain-of-custody. All samples were submitted to Research & Analytical Laboratories, Inc. (R&A), a North Carolina certified laboratory, for analysis. 4.2 Stream Sampling Surface water sampling took place on September 28, 2015. Sample 8103-SW-2 was collected from a tributary of Cleghorn Creek immediately upstream from the confluence. This stream flows to the southwest along the northwest boundary and south along the west boundary of the landfill property. Sample 8103-SW-3 was collected from Stonecutter Creek, a stream that flows to the southwest along the southeastern toe of the landfill. Sample 8103-SW-4 was collected from the same stream as 8103-SW-2 approximately 2,500 feet upstream on the northern boundary of the landfill property. The original 8103-SW-5 sampling location is an intermittent stream downgradient from the C&D landfill. This feature drains into the Cleghorn Creek tributary upstream from the 8103-SW-2 sampling location. This location is usually dry and rarely available for sampling; therefore, the sampling location has been moved to the Cleghorn Creek tributary 50 Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 7 feet upstream from the intersection with the drainage feature. Comparison of the data collected at the new location with the 8103-SW-2 data should reveal whether or not conditions upgradient from the drainage feature are impacting surface water quality. The new location is designated 8103-SW- 5a and is shown on Figure 2. Immediately upon collection, pH, temperature, and conductivity were measured and recorded on the surface water sampling field data sheets. A surface water sampling field data sheet for each location is included in Appendix A and the field data are summarized in Table 2. All stream samples were analyzed for the same Appendix I and C&D parameters as the groundwater samples. The stream sample locations are shown on Figure 2. 4.3 MNA Sampling The October 2007 event was the first to include a comprehensive set of baseline MNA parameters. The subsequent history for the semi-annual sampling events designed to evaluate the effectiveness of MNA as a groundwater protection strategy is documented in Table 8. The MNA performance wells are 8103-MW-2, 8103-MW-4, 8103-MW-6, 8103-MW-8, 8103-MW-9, 8103-MW-10D, and 8103-MW-11A. 8103-MW-4, 8103-MW-10D, and 8103-MW-11A have dedicated bladder pumps, and were purged and sampled in general accordance with the EPA guidelines for low-flow groundwater sampling. Low-flow sampling was accomplished in 8103-MW-2, 8103-MW-6, 8103-MW-8, and 8103-MW-9 using a properly decontaminated portable pneumatic pump and dedicated tubing. 5.0 RESULTS 5.1 Groundwater 5.1.1 Analytical Results Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 8 The results of the laboratory analyses for Appendix I constituents in the groundwater monitoring wells are summarized in Tables 3 and 4. Table 5 summarizes the results of the laboratory analyses for triggered Appendix II constituents. Table 6 summarizes the results of the laboratory analyses for MNA parameters in 8103-MW-2, 8103-MW-4, 8103-MW-6, 8103-MW-8, 8103-MW-9, 8103- MW-10D, and 8103-MW-11A.

The results of the laboratory analyses for C&D parameters are presented in Table 7 and discussed in Section 5.4. 5.1.2 Hydraulic Conductivity In-situ hydraulic conductivity tests were performed on wells 8103-MW-2, 8103-MW-4, 8103-MW- 6, 8103-MW-7, 8103-MW-8 and 8103-MW-9 on March 20, 1995. These tests resulted in hydraulic conductivity values ranging from 2.9 x 10-6 to 1.6 x 10-4 cm/sec. These data are included in Table 9 and were used to calculate groundwater flow velocities across the site. A complete discussion of the test methods and calculations is presented in BPA Environmental & Engineering’s July 7, 1995, report "Monitoring Well System Upgrade, Central Sanitary Landfill, Rutherford County, North Carolina." 5.1.3 Groundwater Flow Direction and Rate The static levels in the monitoring wells were measured September 28-October 7, 2015. The depths to the water table ranged from 8.94 to 82.35 feet below the tops of well casings on these dates and groundwater elevations ranged from 803.37 to 949.39 feet. Groundwater and well casing elevation data are included in Table 1. A groundwater contour map was constructed and is presented as Figure 2. Based on field data, groundwater appears to be flowing in a radial pattern from the fill area towards the east, south, and west. Groundwater flow lines were drawn through each well as shown on Figure 2. The groundwater gradient at each well was calculated assuming a constant groundwater gradient along the flow line between adjacent groundwater elevation Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 14 contours, two monitoring wells along the same flow path, or between a well or contour line and the nearest stream. Based on a variation of Darcy's Law, the rate of groundwater movement within the regolith aquifer was calculated at each monitoring well using the following equation: V = Ki n where V = velocity (ft/day) K = hydraulic conductivity (ft/day) i = groundwater gradient (ft/ft) n = porosity (dimensionless) Calculated hydraulic conductivity and gradient values and estimated effective porosity values for each well were used in the velocity calculations. The 20 percent effective porosity value is based on porosity and specific yield versus grain size distribution relationships presented in Fetter (1988) and is typical for the type of soil (sandy silt with some clays) comprising the regolith at the landfill. The calculated groundwater velocities ranged from 0.53 to 21.42 ft/yr (average = 8.25 ft/yr) and are included in Table 9. 5.2 Surface Water No Appendix I inorganic constituents exceeded the 2B Standards in any of the four surface water samples collected on September 28, 2015.

Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 16 The results of the laboratory analyses for Appendix I constituents in the surface water samples are summarized in Tables 10 and 11, and the complete laboratory reports are included in Appendix B. 5.3 Monitored Natural Attenuation Evaluations of MNA performance based on the results of semi-annual samples collected since October 2007 are encouraging. The presence and ratios of reductive dehalogenation chlorinated ethenes and other MNA parameter concentrations in the wells that are in the primary plume migration routes (8103-MW-4, 8103-MW-6, and 8103-MW-11A to the west and 8103-MW-10D to the east) are consistent with the impacts expected from biodegradation processes at work in a mixed contaminant plume. MNA parameters that exceeded 2L Standards are listed in Section 5.1.1. The results of the MNA field parameter measurements are included in Table 2, and the results of the MNA laboratory parameter analyses are presented in Table 6. The MNA data are presented in Electronic Data Deliverable format in Appendix B (EDD Sep-Oct 2015 MNA). 5.4 C & D Monitoring The ground and surface water sample analyses revealed that three C&D parameters exceeded the 2L or NCGP Standards for groundwater and one parameter exceeded the 2B Standard for surface water. The groundwater parameters are listed in Section 5.1.1 and included below. The below results also include surface water results. A complete summary of the C&D laboratory data is provided in Table 7. The C&D data are presented in Electronic Data Deliverable format in Appendix B (EDD Sep-Oct 2015 C&D). • Iron was detected in 8103-MW-2 at 22,100.0 ppb, 8103-MW-3 at 4,950.0 ppb, 8103-MW- 13 at 1,690.0 ppb, 8103-MW-14 at 1,290.0 ppb, 8103-MW-15 at 519.0 ppb, and 8103-SW- 3 at 1,500.0 ppb.

Results below 0.20 ppb are estimated (J) values. 5.5 Notifications Groundwater constituent concentrations that exceeded the 2L or NCGP standards are listed in Section 5.1.1, Section 5.3, Section 5.4, and in Tables 3, 4, 5, 6, and 7. Surface water constituent concentrations that exceeded the 2B standards are listed in Section 5.2 and in Tables 7, 10, and 11. A summary of groundwater notifications is provided in Table 12 and a summary of surface water notifications is provided in Table 13. The volatile organic constituents present in the groundwater samples are likely due to past waste disposal activities; however, contributions by ongoing borrow, maintenance, and transfer station activities cannot be ruled out. Continued operation of the C&D facility adjacent to the old disposal area is also a potential contributor. There is no evidence indicating that volatile organic constituents resulting from waste disposal at Central Landfill currently exceed the 2L or NCGP Standards at locations beyond the facility boundary. The inorganic constituents present in the groundwater samples may have been influenced by past waste disposal, but it is likely that local geology has an impact. The sample from the upgradient well, 8103-MW-2, had a very low concentration of 1,4-dichlorobenzene for this sampling round. This well typically shows no detectable volatile organic impacts but shows a number of inorganic concentrations similar to those in downgradient wells. The surface water sample location that is upgradient from all facility operations (8103-SW-4) shows inorganic constituent concentrations that are similar to those detected in the downgradient surface water samples. 5.6 Quality Assurance Rutherford County Central Sanitary Landfill April 11, 2016 Rutherford County, NC Page 18 A duplicate sample was collected from 8103-MW-7 and submitted for analysis as "Duplicate." This sample was analyzed for Appendix I volatile organic constituents. 1,4-dichlorobenzene and cis-1,2-dichloroethene were detected at or slightly above the MDL in the original sample but were BQL in the duplicate. All other Appendix I volatile organic results are consistent with the 8103- MW-7 results. The results of the duplicate sample analyses are included in Appendix B. Trip blank samples accompanied the sample bottles from the time they left the laboratory until their return. The laboratory did not report the presence of any Appendix I constituents above the detection in the trip blank sample.
