All sampling was conducted according to North Carolina Solid Waste Management Guidelines. The samples were submitted to a North Carolina certified laboratory and tested for the Federal Appendix I list of volatile organic constituents for detection monitoring and the eight RCRA metals. Results from the monitoring well sample analyses show that the concentrations of three RCRA metals (arsenic in 8102-MW-2A; chromium in 8102-MW-2A, 8102-MW-5, 8102-MW-6, and 8102- MW-7; and lead in 8102-MW-7) exceeded the 15A NCAC 2L (2L) Standard for Class GA groundwater on the date that the samples were collected. Barium, cadmium, chromium, lead, and mercury were detected in one or more of the monitoring well samples at concentrations that did not exceed the 2L Standards. Results from the monitoring well sample analyses show that the concentrations of four Appendix I volatile organic constituents (1,1-dichloroethane in 8102-MW-1; benzene in 8102-MW-1; methylene chloride in 8102-MW-1; and vinyl chloride in 8102-MW-3, 8102-MW-5, and 8102- MW-6) exceeded the 2L Standards on the date that the samples were collected. Thirteen Appendix I volatile organic constituents (1,1-dichloroethane; 1,1-dichloroethene; 1,2-dichloroethane; 1,4- diclorobenzene; acetone; benzene; chlorobenzene; chloroethane; chloroform; cis-1,2- dichloroethene; tetrachloroethene; total xylenes; and trichloroethene) were detected in one or more of the monitoring well samples at concentrations that did not exceed the 2L or NC Groundwater Protection (NCGP) Standards. 1,4-dioxane was detected in 8102-MW-2A, 8102-MW-5, and 8102-MW-6 at concentrations that exceeded the 2L Standard. May 2019 Sampling Report June 25, 2019 Rutherford County South Landfill Page 1 1,4-dioxane was detected in 8102-SW-2 at 5.2 ppb. There is no established 2B standard for this constituent. One RCRA metal (mercury in 8102-SW-2) was detected at concentrations that exceeded the 15A NCAC 2B Standard for Class B/C Surface Waters (213) in the surface water samples collected from the creek that flows along the northeast boundary of the landfill property. One RCRA metal that does not have an established 2B standard (barium) was detected in both surface water samples. Three RCRA metals (chromium in 8102-SW-1 and 8102-SW-2, lead in 8102-SW-2, and mercury in 8102-SW-1) were detected at concentrations below the 2B Standards. 2.0 INTRODUCTION Scarlett Geophysical Consulting, P.C. (SGC) was contracted by Rutherford County, North Carolina, to sample the ground and surface water at ten monitoring well and two surface water locations at the Rutherford County South Landfill. The site location is shown on Figure 1. 3.0 SCOPE OF WORK The scope of work for this sampling event was to sample ten monitoring wells and two stream locations for Federal Appendix I volatile organic constituents as listed in 40 CFR, Part 258, and the eight RCRA metals, and to prepare and submit reports to the client and NC Division of Solid Waste Management documenting the sample collection procedures and analytical results. 4.0 METHODS EMPLOYED 4.1 Monitoring Well Sampling Groundwater sampling took place on May 10, 2019. Water levels were measured in each well to provide data for water volume calculations (Table 1). The wells were then purged by removing three well volumes or bailing the wells dry prior to obtaining water samples. The water samples were collected using properly decontaminated Teflon bailers. Immediately upon collection, the May 2019 Sampling Report June 25, 2019 Rutherford County South Landfill Page 2 water samples were field tested for temperature, specific conductance, and pH. These data are summarized in Table 2. Field data sheets are included as Appendix A. Samples were placed in laboratory cleaned and supplied containers, packed on ice, and placed under chain -of -custody. Samples were shipped to the laboratory under chain -of -custody upon completion of the field work. Analyses were conducted by Research & Analytical Laboratories, Inc., a North Carolina certified laboratory. The monitoring well locations are shown on Figure 2. 4.2 Stream Sampling Surface water sampling took place on May 10, 2019. Samples 8102-SW-1 and 8102-SW-2 were collected from a stream that flows southeastward along the northeast boundary of the South Landfill property. This stream flows into the Second Broad River, which bounds the landfill to the east. All stream samples were analyzed for the same parameters as the ground water samples. The stream sample locations are shown on Figure 2. 5.0 RESULTS The results of the laboratory analyses are summarized in Tables 3 and 4, and the complete laboratory reports are included as Appendix B. 5.1 Groundwater The groundwater sample analyses revealed eight constituents that had concentrations at or above the 2L Standards in one or more of the wells sampled. These analytical results are listed below and shown in the Notification Table (Table 5). • Arsenic was detected in 8102-MW-2A at 10.4 ppb. The 2L Standard is 10.0 ppb. • Chromium was detected in 8102-MW-2A at 28.2 ppb, 8102-MW-5 at 15.0 ppb, 8102-MW- 6 at 10.7 ppb, and 8102-MW-7 at 57.2 ppb. The 2L Standard is 10.0 ppb. • Lead was detected in 8102-MW-7 at 17.0 ppb. The 2L Standard is 15.0 ppb. • 1,1-Dichloroethane was detected in 8102-MW-1 at 57.7 ppb. The 2L Standard is 6.0 ppb. May 2019 Sampling Report June 25, 2019 Rutherford County South Landfill Page 3 • 1,4-Dioxane was detected in 8102-MW-2A at 11.2 ppb, 8102-MW-5 at 24.2 ppb, and 8102- MW-6 at 53.7 ppb. The 2L Standard is 3.0 ppb. • Benzene was detected in 8102-MW-1 at 1.2 ppb. The 2L Standard is 1.0 ppb. • Methylene chloride was detected in 8102-MW-1 at 14.1 ppb. The 2L Standard is 5.0 ppb. • Vinyl chloride was detected in 8102-MW-3 at 0.2 ppb, 8102-MW-5 at 2.7 ppb, and 8102- MW-6 at 0.5 ppb. The 2L Standard is 0.03 ppb. The following constituents were detected in one or more of the wells at concentrations above the method detection limits (MDL) but below the 2L or NCGP Standards. The analytical results are documented in Table 3 and Table 4. • Barium • Cadmium • Chromium • Lead • Mercury • 1, 1 -Dichloroethane • 1, 1 -Dichloroethene • 1,2-Dichloroethane • 1,4-Dichlorobenzene • Acetone • Benzene • Chlorobenzene • Chloroethane • Chloroform • cis-1,2-Dichloroethene • Tetrachloroethene • Total xylenes • Trichloroethene The volatile organic constituents present in the groundwater samples are likely due to past waste disposal; however, contributions by ongoing farming activities immediately north and south of the May 2019 Sampling Report June 25, 2019 Rutherford County South Landfill Page 4 old property boundaries and vehicles involved in active maintenance of the landfill cover cannot be ruled out. Groundwater flow direction data indicate that all groundwater from the disposal area is intercepted by perennial streams to the north, south, and east. There is no evidence indicating that volatile organic constituent concentrations resulting from waste disposal at South Landfill currently exceed the 2L or NCGP Standards at locations beyond the property boundaries. The interval since the last waste disposal suggests that significant impacts on groundwater contamination from the source area are unlikely to increase in the future. The inorganic constituents present in the groundwater samples may be influenced by past waste disposal, but it is likely that local geology has an impact. 8102-MW-4A, which is upgradient from the waste disposal area (see Figure 2), shows minimal volatile organic impact, yet historically has shown inorganic constituent concentrations similar to those in the downgradient monitoring wells. The presence of measurable concentrations of barium, chromium, and mercury in the upgradient surface water sample for this event in addition to cadmium and selenium during prior events suggests the likely influence of contributions from off site sources (local geological and/or cultural). 5.2 Surface Water The surface water sample analyses revealed one constituent with concentrations above the 2B Standard. This analytical result is listed below and shown in the Notification Table (Table 5). • Mercury was detected in 8102-SW-2 at 0.05 ppb. The 2B Standard is 0.012 ppb. One RCRA metal (listed below) for which no standard has been established was detected at a concentration above the MDL and below the Solid Waste Section limit. • Barium concentrations exceeded the MDL (1.1 ppb) in 8102-SW-1 and 8102-SW-2. No 2B Standard has been established for barium. May 2019 Sampling Report June 25, 2019 Rutherford County South Landfill Page 5 Two constituents (chromium in 8102-SW 1 and 8102-SW-2 and mercury in 8102-SW-1) were detected in the surface water samples at concentrations above the method detection limits (MDL) but below the 2B Standards. One volatile organic constituent for which no 2B Standard has been established was detected in one surface water sample. • 1,4-Dioxane was detected in 8102-SW-2 at 5.2 ppb.
