SCS Engineers, PC (SCS) was contacted by the County to address the issue for them. The letter outlined two alternatives for the County’s response, which are: initiate an assessment monitoring program, or initiate an Alternate Source Demonstration (ASD). Since Appendix I Inorganic Constituent Exceedances in the monitoring wells have been documented since before waste was placed in the landfill and on a continuing basis since baseline sampling, an assessment program is not justified. This ASD includes a geological review, total and dissolved metals groundwater sampling, and statistical analyses using both historical baseline groundwater data and compliance monitoring data upgradient and downgradient of the units being monitored. Monitoring wells downgradient of the unlined Construction and Demolition disposal cell (MW-12, MW-12D, MW-14, MW-14D, MW-15, and MW-15D) are not subject to the ASD requirements and were therefore not included in this report. 2 GEOLOGIC SETTING The Buncombe County Landfill site is located in the Blue Ridge Mountains approximately 9 miles north of Asheville, North Carolina. The landfill site consists of 557 acres bounded by the French Broad River to the south and west, Blevin Branch to the north, and Flat Creek to the east. The site consists of moderate to steep slopes separating narrow hills and ridges from small incised secondary drainages. The Buncombe County Landfill Site Figure is provided as Appendix A. 3 SITE GEOLOGY The Geologic Map of North Carolina shows the site to be underlain by a Precambrian Migmatitic biotite-hornblende gneiss unit (NCGS 1985). The site vicinity was mapped as primarily granite and undifferentiated gneiss (Weiner 1970 and GRAM 1999). Small localized areas of alluvium and/or colluvium were encountered near the base of the secondary drainage features. These soils generally consisted of clays to silty sand with rock fragments. Typically, the uppermost layer consisted of residuum soils (saprolite) which generally consist of stiff sandy silts and dense clay. The saprolite grades into partially weathered rock (PWR). The thickness of saprolite and PWR was greatest in upland areas, and least in the bottom of secondary drainage features. Depth to bedrock, ranges from 3.5 feet to 29 feet. The top of bedrock is typically a reflection of surface topography, with shallow bedrock in the secondary drainage features, and deeper bedrock in upland areas. 4 SITE HYDROGEOLOGY As with bedrock, the potentiometric surface is a subdued reflection of surface topography. The bedrock fracture flow system behaves similar to an anisotropic porous media, based on the Alternate Source Demonstration 2 potentiometric mapping results of pumping tests conducted during previous investigations at the Buncombe County site (CDM, 1995, 2002). Groundwater Contour Maps from the October 2016 Semi-Annual Sampling event are provided in Appendix A. Dissolved chemicals in groundwater may be derived from rock weathering, biological processes, and anthropogenic sources. Dissolution of minerals in bedrock and overlying geologic materials commonly release naturally occurring constituents to the groundwater (Chapman and others, 2013). Groundwater from diverse environments may contain naturally occurring trace elements such as iron, manganese, zinc, lead, copper, nickel, vanadium, molybdenum, and arsenic (Rose and others, 1979). According to Naturally Occurring Contaminants in the Piedmont and Blue Ridge Crystalline- Rock Aquifers and Piedmont Early Mesozoic Basin Siliciclastic-Rock Aquifers, Eastern United States, 1994–2008, dissolved concentrations of trace constituents can range widely depending on their occurrence in the saprolite and PWR (Chapman and others, 2013). 5 REGIONAL STREAM SEDIMENT A geochemical atlas of North Carolina, U.S.A. was prepared using National Uranium Resource Evaluation (NURE) stream-sediment data. Stream sediment of weathered bedrock typical of the nearby source formations was developed to assist mineral exploration. These data also serve to provide a baseline from which to assess naturally occurring metals in landfill saprolite and PWR. The maps included herein represent findings for arsenic, barium, beryllium, chromium, cobalt, copper, iron, lead, manganese, nickel, selenium, silver, vanadium, and zinc. The sediment graphics indicate the natural presence of the metals in the soils of that region of the state where the landfill is located. Note that the sediment study did not include antimony, cadmium, and thallium. However, the presence of the other metals at the site would indicate that naturally occurring metals in the mountain region are common. Stream Data Maps are provided as Appendix B. 6 GROUNDWATER MONITORING The Solid Waste Management Rule 15A NCAC 13B.1632 requires new MSWLF units establish background groundwater quality to demonstrate compliance with groundwater monitoring requirements. The initial baseline sampling event for the Buncombe County Solid Waste Management Facility was completed in October 1996 with the remaining three background sampling events completed in June, August, and September of 1997. Monitoring the background wells MW-1 and MW-1D, and the compliance wells MW-2, MW-2D, MW-3, MW-4, MW-4D, MW-5, MW-5D, MW-6, MW-7, MW-8, MW-8D. Arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, nickel, vanadium, and zinc were all detected in the baseline sampling events prior to beginning operations. Exceedances of the North Carolina groundwater standards were noted also for the metals barium, chromium, lead and nickel as shown in Table 1 Initial Baseline Sampling, Appendix C. Alternate Source Demonstration 3 Since the Buncombe County Landfill (Permit #11-07) initially opened, the groundwater and surface water has been monitored twice annually. Many of the wells, including background, show metals detections. Background well MW-1 has shown detectable concentrations of additional metals antimony, iron, manganese, selenium, silver, and thallium since the baseline sampling. Background well MW-1D has shown detectable concentrations of additional metals iron, manganese, and silver since the baseline sampling. The background and compliance wells on the site have shown detections of metals above the exceedance level since the initial reports in 1998 were filed with the North Carolina Department of Environment and Natural Resources. Antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, iron, lead, manganese, nickel, thallium, and vanadium have all been detected above groundwater quality standards. Compliance Monitoring Well Exceedance Summary Report is provided as Appendix D. 7 TIME SERIES GRAPHS Graphical methods are typically used with quantitative statistical evaluations. Graphical methods provide information that may not be otherwise apparent from quantitative statistical evaluations, so it’s good practice to evaluate data using these methods prior to performing statistical evaluations. Time series graphs of the metals concentrations and field turbidity measurements demonstrate a strong correlation with turbidity measurements for the metals barium, beryllium, cadmium, chromium, iron, lead, manganese, nickel, and vanadium. Arsenic, cobalt, and thallium time series graphs did not correlate well with turbidity measurements because of small data sets and changing laboratory detection limits. Time Series Graphs are provided as Appendix E. Outliers data which appears anomalous or outside the range of expected values may indicate errors, may indicate data unrelated to the rest of the data set, or may be perfectly valid data that indicates contamination or unusual hydrogeological conditions. Possible reasons for outliers are recording errors, unusual sampling and laboratory procedures or conditions, or inconsistent sample turbidity. The trend of decreasing turbidity and metals concentrations can be attributed to better sampling equipment and methods practiced over the years. To try to ascertain whether or not the metals were in the water and not suspended particles, SCS previously tested filtered samples and additionally redeveloped some of the wells resulting in lower concentrations between filtered and unfiltered samples. SCS again tested filtered samples in the last semi-annual groundwater monitoring event where turbidity measurements were lower than historical sampling turbidity measurements. Dissolved metals concentrations were only marginally below the unfiltered sample concentrations. The results of the Fall 2016 activities would indicate that the metals are dissolved in the groundwater. 8 STATISTICAL ANALYSIS Background is defined as groundwater which is not influenced by releases from a site. Specifically, a background groundwater data set may represent either a location or a time period that has not been influenced by a release from the site. The concentration of a chemical will Alternate Source Demonstration 4 naturally vary both spatially and temporally. The analytical process introduces additional variability. Because of both natural and introduced variability, background can best be understood as a distribution (ITRC, 2013). Statistical analysis was performed to determine if the distribution of concentrations are consistent with the distribution of concentrations in background samples. In accordance with Solid Waste Management Rule 15A NCAC 13B.1632, historical compliance groundwater monitoring data were pooled and the analytical results were used to create a statistical baseline for statistically significant increases in constituent concentrations. The parametric analysis of variance (ANOVA) is a statistical method which is used to do the analysis of variance between and within multiple groups of data. The ANOVA tests the null hypothesis that samples in two or more groups are drawn from populations with the same mean values. Chemstat 6.2.1.0 statistical software was used to analyze the compliance monitoring data. Parametric ANOVA analysis. The Parametric ANOVA analysis showed no statistical difference between compliance well metal concentrations and background well data for antimony, arsenic, cadmium, iron, manganese, and thallium. The Parametric ANOVA analysis showed a statistical difference between compliance well metal concentrations and background well data for barium, beryllium, chromium, lead, nickel, and vanadium. There were no detectible concentrations of cobalt in the compliance monitoring samples and the parametric test could not be performed, it should be noted however that cobalt was detected in the background wells during baseline sampling. Parametric ANOVA Analysis results are provided as Appendix F. Intrawell comparisons were made where statistically different metals exceedances were noted. Concentrations of barium were statistically higher than background (MW-1/ MW-1D compliance data) concentrations in MW-2. Barium was detected in MW-2 during the baseline sampling at a concentration higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-2. Concentrations of beryllium were statistically higher than background concentrations in MW-2 and MW-6. Beryllium was detected in MW-2 and MW-6 during the baseline sampling at concentrations higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-2 and MW-6. Concentrations of chromium were statistically higher than background concentrations in MW-6. chromium was detected in MW-6 during the baseline sampling at a concentration higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-6. Concentrations of lead were statistically higher than background concentrations in MW-2. Lead was detected in MW-2 during the baseline sampling at a concentration higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-2. Concentrations of nickel were statistically higher than background concentrations in MW-7. Nickel was detected in MW-7 during the baseline sampling at a concentration higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-7. Concentrations of vanadium were statistically higher than background concentrations in MW-6 and MW-7. Vanadium was detected in MW-6 during the baseline sampling at a concentration Alternate Source Demonstration 5 higher than the compliance monitoring results demonstrating natural occurrence for this constituent in MW-6 and MW-7. 9 CONCLUSION The ASD is being performed to demonstrate that natural variability in the fractured bedrock and saprolite aquifer system has resulted in metals concentrations that vary both spatially and temporally. This natural variation was identified as the source of the sporadic detections of metals above its background limit. Metal concentrations in the groundwater have been shown to be naturally occurring substances present in the environment. This natural variation has been documented in stream sediments, baseline groundwater sampling conducted before waste was placed in the landfill, and quantitative statistical evaluations. 10 REFERENCES CDM, 1997.
