Groundwater, surface water, underdrain, and leachate sampling were completed by Environmental Sampling & Services, Inc. (ES&S) on February 1, 2021, and analytical testing was performed by Pace Analytical Services, LLC. The statistical analysis software package utilized, Sanitasr', follows a documented decision logic that incorporates the following applicable document: USEPA "Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities, Unified Guidance" (March 2009). 2.0 SITE BACKGROUND AND MONITORING NETWORK In compliance with North Carolina Department of Environmental Quality (DEQ) Solid Waste Management Regulations, Section .1600 "Requirements for Municipal Solid Waste Landfill Facilities," Jett Environmental Consulting statistically evaluated parameters from the First Semi -Annual 2021 event using inter -well prediction interval analysis. Prediction intervals are considered a powerful tool for groundwater statistical analysis, when feasible, due to their inherent low false negative and false positive rates utilizing confirmatory resampling, if necessary. The facility's monitoring network is comprised of eleven monitoring wells: MW-1 R2 (background), MW-2R, MW-3R2, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, and MW-11, which monitor the uppermost aquifer beneath the facility. The monitoring wells are sampled on a semi-annual basis, with the groundwater samples submitted to a qualified laboratory for required analyses in accordance with the facility's environmental monitoring program and permit requirements. The monitoring wells are equipped with dedicated bladder pumps and were purged and sampled via the low -flow method. Table 1 lists the groundwater monitoring wells for the site. Each of the wells was sampled during the First Semi -Annual 2021 event. Groundwater monitoring was initiated in August 1998. Statistical background is defined as samples collected from former upgradient well MW-1, former upgradient well MW-1 R, and current upgradient well MW-1 R2 from 1998 through the current event. The parameters subject to statistical evaluation during detection monitoring are noted in DEQ Section .1633 as constituents listed in Appendix I of 40 CFR Part 258 "Constituents for Detection Monitoring". The following is a chronology of well replacement and abandonment. Well MW-3R2 was added to the monitoring well network on August 17, 2006 as a replacement well for MW-3 and MW-3R. Monitoring wells MW-3 and MW-3R remain for water level data collection purposes only. Monitoring well MW-7 was installed in April 2010 to monitor groundwater beneath Cell 4, which began receiving waste in September 2010. MW- 8 was installed in April 2013 to monitor Cell 8A, which was constructed in January 2013. MW-10 was installed in October 2015 to monitor Cell 5A. The former background well MW-1 was abandoned in preparation for construction of Cell 5A and the new background well, MW-1 R, was installed in October 2015. MW-9 was installed June 2016 to monitor Cell 5A. Soil and bedrock removal in the Northern Borrow Area rendered well MW-1 R dry and inaccessible. Therefore, a replacement monitoring well (MW-1 R2) was installed in September 2018. New well MW-11 was also installed in September 2018 as part of the Cell No. 513 construction. The site has a surface water monitoring network consisting of one upstream surface water sampling point (SW-1) and four downstream points (SW-2, SW-3, SW-4, and SW-5). These points are sampled semi- annually for the 40 CFR Part 258 Appendix I list in conjunction with the groundwater monitoring wells. Each surface water monitoring point was sampled during the First Semi -Annual 2021 event. A sample point from the underdrain for Cell 1 (LID-1) was added to the monitoring program prior to the January 2008 sampling event. A sample point from the underdrain for Cells 4 and 8A (LID-2) was added to the monitoring program prior to the January 2014 sampling event. The underdrains are to be sampled Groundwater Statistical Analysis Report Foothills Regional Landfill, North Carolina 2 semi-annually (contingent on flow availability) for the 40 CFR Part 258 Appendix I list. Both underdrains were able to be sampled during the First Semi -Annual 2021 event. A leachate sample is also routinely collected for analysis. The leachate sample was analyzed for the 40 CFR Part 258 Appendix I list, biochemical oxygen demand, chemical oxygen demand, nitrate as N, nitrite as N, phosphorus, and sulfate. In accordance with a November 28, 2018 DEQ letter, 1,4-dioxane is no longer required be analyzed for the groundwater and surface water samples; however, will be analyzed annually for the leachate sample. The leachate was sampled and analyzed for 1,4-dioxane during the First Semi -Annual 2021 event. The facility was in an Assessment Monitoring Program in 2006. An Alternate Source Demonstration (ASD) for volatile organic compounds (VOCs) detected in wells MW-3 and MW-3R was approved by DEQ on December 14, 2006, and the facility reverted to a Detection Monitoring Program. An ASD for cobalt and a request to use background as the groundwater protection standard (GWPS) for cobalt was submitted to the DEQ in November 2016. The ASD is currently under DEQ review. An ASD for benzene and vinyl chloride at MW-2R was submitted to DEQ in June 2017; however, it was not approved in a letter from DEQ dated October 11, 2017 and Assessment Monitoring was initiated. Therefore, during the First Semi -Annual 2018 event, the initial Appendix II Assessment constituent list was sampled at each well. The constituents detected at quantifiable concentrations (barium, benzene, and cobalt) were consistent with past events and also on the Appendix I Detection Monitoring list. On May 18, 2018, the site requested deleting all non -Appendix I monitoring from future sampling events, with the exception of well MW-2R, which will continue with annual Appendix II monitoring. In correspondence dated July 9, 2018, DEQ approved the request to only include MW-2R for future annual Appendix II monitoring. The annual Appendix II monitoring for MW-2R was performed during the First Semi -Annual 2021 event. No Appendix II constituents, not also on the Appendix I list, were detected above their respective laboratory Practical Quantitation Limits (PQLs) during the First Semi -Annual 2021 event. The next annual Appendix II sampling event for MW-2R will be the First Semi -Annual 2022 event. 3.0 SITE HYDROGEOLOGY The following site hydrogeology summary was taken from the Second Semi -Annual Water Quality Monitoring Report of 2017, dated November 17, 2017 by Joyce Engineering. Geologically, the facility is located in the northwestern portion of the Inner Piedmont Belt of the Piedomont Physiographic Province, approximately 20 miles east of the thrust belt (Brevard Shear Zone) delineating the boundary between the westerly Blue Ridge Belt and the easterly Inner Piedmont Belt. The metamorphic rocks of the Inner Piedmont Belt generally group within the sillimanite facies of the amphibolite metamorphic sequence. Locally, the bedrock underlying the facility has been mapped as migmatitic granitic gneiss of the Ordovician and older Cambrian Periods. These rocks are described as ranging in composition from granitic to quartz dioritic with smaller biotite gneiss and amphibolite facies present locally. The unit as a whole exhibits a variable massive to foliated fabric. The uppermost aquifer beneath the facility is present within weathered bedrock saprolite and fractured bedrock. The saprolite ranges in texture from clayey silt in the upper, most weathered sections to micaceous sandy silt in the lower sections. Immediately above the competent bedrock surface, a variable thickness transitional zone composed of highly weathered and degraded friable bedrock is present. The uppermost aquifer is laterally continuous across the site, with depth to water ranging from less than 31 feet in low-lying areas to greater than 77 feet beneath topographic highs. Groundwater in the uppermost aquifer generally flows from recharge areas associated with broad gently sloping topographic areas towards topographically lower areas that are generally delineated by the presence of stream channels, some of which are perennial receiving streams (groundwater discharge areas) and others of which are intermittent Groundwater Statistical Analysis Report Foothills Regional Landfill, North Carolina 3 discharging streams. In the vicinity of the facility, the general groundwater flow direction is towards the south and west. Appendix A provides a potentiometric surface map utilizing groundwater level data from the First Semi - Annual 2021 event. Groundwater flow direction for the First Semi -Annual 2021 event was to the southwest, which is consistent with previous interpretations for this facility. Groundwater flow rate for the First Semi - Annual 2021 event was estimated at 176 feet/year, consistent with past events. Flow rate calculations are available in Appendix A. 4.0 DATA EVALUATION Appendix C contains a copy of the laboratory analytical report and field sampling forms for the First Semi - Annual 2021 groundwater, surface water, underdrain, and leachate sampling event. The analytical results for the First Semi -Annual 2021 event for the groundwater, surface water, underdrain, and leachate samples are summarized on Tables 2, 3, 4, and 5, respectively. Two VOCs were detected at a quantified concentration at or above a PQL in the groundwater samples: benzene at MW-2R and toluene at MW-8. The trace level VOC detections are typical for the site. As shown on Table 2, two Appendix I inorganic constituents (barium at MW-2R, MW-5, and MW-6; and cobalt at MW-4 and MW-6) were detected at quantified concentrations. Two Appendix I constituents (benzene at MW-2R and cobalt at MW-4 and MW-6) were detected above an NC Interim Maximum Allowable Concentration (IMAC) or 2L Standard during the First Semi -Annual 2021 sampling event. Cobalt (MW-8) and vanadium (MW-10) were detected above their respective IMAC, however at estimated concentrations below their PQL. Per 15A NCAC 02L .0202(b)(1), for the NC 2L Standards and NC IMAC Standards, only detections of a substance at or above the PQL can constitute a violation of the standard. Therefore, estimated values below the PQL are not considered a violation of a NC 2L Rule standard. As shown on Table 3, during the First Semi -Annual 2021 event, no inorganics were detected in surface water samples at quantified concentrations above a respective NC 2B Surface Water Standard. No VOCs were detected in surface water samples at quantified concentrations above their respective PQLs during the First Semi -Annual 2021 event (see Table 3). During the First Semi -Annual 2021 event, no VOCs were detected in the underdrain samples at quantified concentrations above their respective PQLs (see Table 4). The constituents detected in the leachate sample collected during the First Semi -Annual 2021 event were typical for leachate at this facility (see Table 5). 5.0 STATISTICAL PROCEDURES Statistical analyses (i.e., inter -well prediction limits) were performed to establish background concentrations and determine if the IMAC value -to -value exceedances for cobalt exhibited a statistically significant increase. Statistical analyses (i.e., lower confidence limits) were performed to determine if the 2L Standard value -to -value exceedance for benzene statistically exceeded the 2L Standard. 5.1 Outlier Analysis The background data were evaluated for the presence of statistical outliers. Methodologies for determining a statistical outlier are defined in the USEPA Unified Guidance. Any statistical outliers that were determined were removed from the background data set prior to performing prediction interval statistical analysis. According to the USEPA Unified Guidance above, data that are not normally or log -normally distributed are Groundwater Statistical Analysis Report Foothills Regional Landfill, North Carolina 4 not recommended for evaluation of outliers. In cases where the data were not normally or log -normally distributed, outliers were not removed from the data set. Background outliers flagged for removal are identified on the statistical plots provided in Appendix B. 5.2 Inter -Well Prediction Intervals The prediction interval is a statistical method used to compare a single observation to a group of observations. The prediction interval is calculated to include observations from the same population with a specified confidence. In groundwater monitoring, a prediction interval approach may be used to make comparisons between background and compliance data. The interval is developed to contain all future observations, within a certain probability. For the site, inter -well prediction intervals have been developed based on a 99% confidence that future observations will fall within the range. If any future observation exceeds the prediction interval, this is considered statistically significant evidence that the observation is not representative of the background group. During parametric prediction interval analysis, the mean and the standard deviation are calculated for the raw or transformed background data. The number of comparison observations, K, is defined to be included in the interval. If less than 15% of the background observations are non -detects, the non -detects are replaced with one half of the reporting limit prior to performing the analysis. If more than 15% but less than 50% of the background data are below the reporting limit, the data's sample mean and standard deviation are adjusted according to the Kaplan -Meier method. However, when the background data are not transformed -normal or contain greater than 50% observations below the reporting limit, SanitasTm automatically constructs a non -parametric prediction interval. During non -parametric analysis, the highest value from the background data is used to set the upper limit of the prediction interval. Due to the wide range of laboratory reporting limits utilized over time, the historical reporting limits were conservatively replaced with the current event reporting limit prior to performing statistical analyses. Summary tables and graphs for the inter -well prediction interval analysis are available in Appendix B. Included in Appendix B are time series plots for each of the inorganic constituents. For the First Semi -Annual 2021 event, two inorganic statistically significant increases were exhibited for the groundwater monitoring wells: cobalt at MW-4 and MW-6. The First Semi -Annual 2021 concentrations of total cobalt at MW-4 (17.4 ug/L) and MW-6 (10.9 ug/L) were above the background inter -well prediction limit based on pooled data from upgradient wells MW-1, MW-1R, and MW-1R2 (10 ug/L, which is equal to the PQL). An ASD for cobalt and a request to use background for the Groundwater Protection Standards (GWPSs) was submitted to the DEQ by the site on November 4, 2016. The statistical background value for cobalt was determined to be 44.1 ug/L based on an Upper Poisson Prediction Limit, which is higher than the detected concentration at MW-4. The ASD requested that the background value be considered the GWPS for cobalt per 15A NCAC13B.1634.(g).5. The ASD is currently under DEQ review. 5.3 Intra-Well Confidence Limits Per DEQ Regulation .1634(H), GWPSs are equal to the National Primary Drinking Water Standard - Maximum Contaminant Level (MCL) or North Carolina 15A NCAC 2L Water Quality Standard, whichever is lower. In instances where an MCL or 2L Standard are not established, the GWPSs were derived from the DEQ-Solid Waste Section published GWPSs. In order to determine if the groundwater concentrations exhibit a statistical exceedance of the GWPS, a statistical comparison was made to the GWPSs to determine if further action is warranted. The following text outlines the procedures that were used to statistically compare concentrations to GWPSs. Groundwater Statistical Analysis Report Foothills Regional Landfill, North Carolina 5 Per the USEPA Unified Guidance, a Confidence Interval is constructed from sample data and is designed to contain the mean concentration of a well analyte in groundwater monitoring, with a designated level of confidence. A confidence interval generally is used when samples are being compared to a GWPS, which is typically the MCL or alternate limit (i.e. 2L Standard or NC IMAC). A lower confidence interval analysis was used to statistically compare to GWPSs. The method constructs a normal confidence interval on the mean concentration of a constituent incorporating, at a minimum, the four most recent measurements. The lower confidence interval on the mean was compared to the GWPS to determine whether the mean concentration exceeded its GWPS. If the lower confidence interval on the mean exceeds the GWPS then there is statistically significant evidence that the mean concentration of that constituent exceeds the GWPS. The distribution of the data is evaluated by applying the Shapiro -Wilk or Shapiro -Francis test for normality to the raw data or, when applicable, transformed data. If less than 15 percent of the observations are non - detects, the non -detects will be replaced with one half the reporting limit prior to performing the normality test and constructing the confidence limit. Per .1634(g)(5), if background (statistical limit based on upgradient well data) is higher than the 2L Standard, then background may be utilized as the GWPS. Background for organics is considered the non - detect level (equivalent to the PQL). Organic concentrations detected above PQLs and GWPSs (See Table 2) were statistically compared to their respective GWPSs utilizing intra-well lower confidence limits. As provided in Appendix B, benzene at MW-2R statistically exceeded the GWPS for the First Semi -Annual 2021 event, consistent with recent events. Time series graphs for VOC detections during recent events are provided in Appendix B. 5.4 Statistical Results Summary For the First Semi -Annual 2021 event, two inorganic statistically significant increases were exhibited for the groundwater monitoring wells: cobalt at MW-4 and MW-6. The First Semi -Annual 2021 concentrations of total cobalt at MW-4 (17.4 ug/L) and MW-6 (10.9 ug/L) were above the background inter -well prediction limit based on pooled data from upgradient wells MW-1, MW-1R, and MW-1R2 (10 ug/L, which is equal to the PQL). However, cobalt concentrations at MW-4 have been slowly decreasing since the July 2012 event (25.4 ug/L). In addition, the First Semi -Annual 2021 concentration of cobalt at MW-6 (10.9 ug/L) was only slightly above the laboratory PQL (10 ug/L). Intra-well lower confidence limits determined benzene at MW-2R (2.0 ug/L) statistically exceeded the GWPS for the First Semi -Annual 2021 event, consistent with recent events. However, benzene concentrations at MW-2R have not increased since the peak concentration in January 2018 (2.6 ug/L). 6.0 CONCLUSIONS For the First Semi -Annual 2021 event, two inorganic statistically significant increases were confirmed exhibited for the groundwater monitoring wells: cobalt at MW-4 and MW-6, consistent with recent events. One Appendix I constituent (benzene at MW-2R) was confirmed detected above an NC IMAC or 2L Standard during the First Semi -Annual 2021 sampling event. Intra-well lower confidence limits determined benzene at MW-2R statistically exceeded the GWPS for the First Semi -Annual 2021 event, consistent with recent events. During the First Semi -Annual 2021 event, no Appendix I VOCs were detected in surface water and underdrain samples at quantifiable concentrations. No quantified detections of Appendix I metals were confirmed to exceed NC 2B Surface Water Standards for surface water points during the First Semi -Annual 2021 event. Groundwater Statistical Analysis Report Foothills Regional Landfill, North Carolina 6 The Foothills Regional Landfill will continue monitoring in accordance with the requirements for Detection and Assessment Monitoring as outlined in Title 15A NCAC 13B .1633 and .1634, respectively. The next semi-annual event is scheduled for July 2021. 7.0 RECOMMENDATIONS Wells in the proximity of MW-2R exist directly upgradient (MW-9) and directly downgradient (MW-3R2). No VOCs have been confirmed detected at quantified concentrations at MW-9 or MW-3R2; therefore, the extent of quantified VOC detections (i.e. benzene) has been defined to only MW-2R. As described in the site's June 2017 ASD for benzene/vinyl chloride at MW-2R, the VOCs appear to be related to landfill gas. Wells MW-9, MW-2R, and MW-3R2 would effectively cover the exterior perimeter of the cell (Cell 1A) suspected as the source of potential gas migration. The site implemented landfill gas extraction and collection upgrades in the Cell 1A area in late 2017 and installed a horizontal active landfill gas collection/mitigation trench in the vicinity of MW-2R in Fall 2018 (see map in Appendix A). Benzene concentrations at MW-2R have not increased since the peak concentration in January 2018 (2.6 ug/L). Two additional events of groundwater monitoring are recommended before any further actions are considered to determine if benzene levels at MW-2R (2.0 ug/L) decrease to levels below the lab PQL (1.0 ug/L) as a result of the landfill gas system upgrades. It is recommended that wells MW-4 and MW-6 continue in Detection Monitoring. The decrease in concentration of cobalt at MW-4 from 25.4 ug/L in July 2012 to 17.4 ug/L during the First Semi -Annual 2021 event, indicates a slow decreasing trend near the laboratory PQL (10 ug/L). The First Semi -Annual 2021 cobalt concentration at MW-6 (10.9 ug/L) was only slightly above the laboratory PQL (10 ug/L). Since the landfill is lined, it is unlikely the cobalt detections are related to a landfill release. The lack of receptors of water use in this shallow well, which would not feasibly produce a well with sufficient yield for potable use, is evidence of a lack of risk associated with this level of detection. Cobalt is naturally occurring at the site, evident by the historical cobalt detections in various wells across this site, and is a common element occurring naturally in minerals commonly found in the bedrock, soil, and sediments in the North Carolina Piedmont. According to A Geochemical Atlas of North Carolina (by Jeffery C. Reid, dated 1993 in the North Carolina Geological Survey's Bulletin 93), which displays the distribution of cobalt in stream sediments across the state, Caldwell County has been highlighted. Cobalt was found at concentrations as high as 10 mg/kg throughout Caldwell County; with a significant amount of variability. Metals in the soil and bedrock can easily leach into the groundwater, especially if the groundwater is acidic (pH < 7.0). The pH of groundwater samples from the Foothills Regional Landfill during the First Semi -Annual 2021 sampling event ranged from 5.17 to 7.98 SU. The pH of the samples from MW-4 and MW-6, which had the highest cobalt concentrations, were 5.17 and 5.63 SU, respectively. Review of leachate data for the last 10 years indicates cobalt has ranged from 7.3 to 37.8 ug/L, with an average concentration of 24.6 ug/L. The occurrence and levels of cobalt at the site has no indication of being related to a release from the waste unit. The site recommends utilizing the upcoming Second Semi -Annual 2021 (July 2021) and First Semi -Annual 2022 (January 2022) events to continue to verify the downward/stable trends of cobalt levels at MW-4/MW- 6 and benzene at MW-2R, since levels are approaching the laboratory PQL of 10 ug/L and 1.0 ug/L, respectively. The proposed actions are protective of human health and the environment and the values at this time do not further action, especially for a naturally occurring element (cobalt).

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited.
