The landfill was operated by Burke County as a municipal solid waste (MSW) landfill between 1972 and 1988 and has been closed to the reception of waste since 1988. 1.2 Regulatory Status The landfill is regulated under Rules .0500 and .0600 of the North Carolina Solid Waste Management Regulations (NCSWMR) for MSW landfills closed prior to October 9, 1993. The County monitors' groundwater at the landfill in accordance with criteria set forth in Rule .0600 of the NCSWMR. In March 1995, the North Carolina Department of Environment and Natural Resources (NCDENR), now the Department of Environmental Quality (NCDEQ), requested that the facility perform additional site contamination investigation activities due to the quantified detections of organic constituents in the groundwater on site. In response to this request a Water Quality Assessment Plan for the East Burke Landfill was submitted to the Solid Waste Section (SWS) in September of 1995. Updates on Groundwater Assessment Activities were submitted to NCDENR SWS in June 2003 and August 2003. 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program Groundwater monitoring at the East Burke Landfill is completed in accordance with the monitoring requirements of Rule .0600 of the NCSWMR. Groundwater samples are collected semiannually. The current compliance network consists of the following monitoring wells: MW-1(background), MW-2, MW-3, and AMW-1. A site plan indicating the facility and waste boundaries in addition to monitoring well locations can be found in Drawing 1. All monitoring wells are monitored for the constituents listed in Appendix I of 40 CFR Part 258 (NC Appendix 1) plus 1,4-dioxane.

Surface water samples are collected semiannually and are analyzed for the NC Appendix I constituents plus 1,4-dioxane. The surface water monitoring network consists of two sampling points: SW-1 located upstream from the sediment pond, and SW-2 located downstream from MW-3 and AMW-1. The approximate locations of the sampling points are shown on Drawing 1. Surface water from the site flows to Rhodhiss Lake, just upstream of the dam. Rhodhiss Lake is Classified and Water Supply IV. Surface Point Classification Monitoring Program SW-1 SW-2 Compliance Compliance .0600 .0600 3.0 MAY 2021 SEMIANNUAL SAMPLING EVENT 3.1 Field Work On May 3, 2021, personnel from LaBella Associates visited the East Burke Landfill to obtain water levels to the nearest 0.01 foot, purge and sample monitoring wells MW-1, MW-2, MW-3, and AMW-1, and sample surface monitoring points SW-1 and SW-2. Monitoring wells were purged and sampled using either disposable bailers or a 12-V submersible pump during the May 2021 sampling event. Measurements of temperature, pH, specific conductivity, dissolved oxygen, oxidation reduction potential, and turbidity were recorded in the site log book prior to purging, after each purge volume, and during sampling. Prior to sampling, laboratory -supplied containers were prepared with the following information: • Monitoring well number (completed by field personnel); • Date and time of sample collection (completed by field personnel); • Initials of sampling personnel (completed by field personnel); • Project name and number (completed by the laboratory); • Chemical preservative (completed by the laboratory); and • Requested chemical analysis (completed by the laboratory). Groundwater samples from each monitoring well were collected directly from the disposable bailers or the tubing for the 12-V submersible pump in the provided laboratory containers within 24 hours of the final purge volume. Immediately after collection, the samples were placed on ice in a laboratory -provided cooler. Copies of the field data logs are provided in Appendix 1. The surface water monitoring points SW-1 and SW-2 were collected directly from stream by lowering a clean, unpreserved sample container into the stream flow and dispensing the water into laboratory -prepared sample containers. Care was taken to avoid May 2021 Semiannual Water Quality Monitoring Report LaBella Associates Burke County - East Burke Landfill, Permit No. 12-02 August 2021 2 sample -induced turbidity. At the time of sampling, surface water was also measured for temperature, pH, specific conductivity, dissolved oxygen, oxidation reduction potential, and turbidity and recorded in the field data log. Immediately after collection, the samples were placed on ice in a laboratory -provided cooler. Copies of the field data logs are presented in Appendix 1. On June 29, 2021, personnel from LaBella Associates visited the East Burke Landfill for a resample of SW-1 and SW-2 for Appendix 1 total metals and dissolved metals. The same surface water procedure was followed for the resample. 3.2 Laboratory Analysis and Quality Control Pace Analytical Services, Inc. of Huntersville, North Carolina received the groundwater and surface water samples on May 5, 2021, and the resampled surface water samples arrived on June 30, 2021, under chain -of -custody control for analysis. LaBella requested a Level II data report for the final laboratory report. The samples were received by the laboratory in good condition, properly preserved, and within analysis hold times. In addition to samples collected for compliance monitoring at the East Burke Landfill, a Field Blank was collected by LaBella Associates personnel as part of the May 2021 sampling event. A Trip Blank was also prepared by the laboratory to accompany the volatile samples during shipment. The Field Blank was analyzed for the NC Appendix I list compounds and 1,4-dioxane while the Trip Blank was analyzed for NC Appendix I VOCs and 1,4-dioxane. Upon receipt of the laboratory data package, the data was reviewed by LaBella personnel for the following: • General typographical errors; • Correct analyses performed and within method specified hold times; • Correct analyte lists; • Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike Duplicate, and Laboratory Control Samples; • Blank qualified data (B-flags); • Detections above the Method Reporting Limits (MRL); • Detections above the 15A NCAC2L (NC2L) Groundwater Standards, NC Interim Maximum Allowable Concentrations (IMACs), 15A NCAC2B (NC2B) Surface Water Standards, or NC In -Stream Target Values (ISTV); and • Detections that are above historical levels. 4.0 HYDROGEOLOGY The surFicial aquifer is believed to include the regolith and the underlying fractured metamorphic bedrock. The regolith consists of residual soils, saprolite, and variably fractured and weathered layered metamorphic rock. In this regard, regolith behaves similar to unweathered bedrock, except that fractures are more numerous and better connected in the regolith, and will tend to have more isotropic hydraulic properties. May 2021 Semiannual Water Quality Monitoring Report LaBella Associates Burke County - East Burke Landfill, Permit No. 12-02 August 2021 3 Groundwater discharges into an unnamed tributary to Lake Rhodhiss, northeast of the landfill. A groundwater potentiometric surface map, developed from static water level data obtained on May 3, 2021 is presented as Drawing 1. Depth to groundwater was measured in the compliance monitoring wells at the site prior to sampling. The groundwater elevations were calculated relative to the surveyed measuring point (top of casing) for each monitoring well to ±0.01 ft. The groundwater elevations are summarized in Table 1 for the May 2021 sampling event. Historical groundwater elevations are summarized in Appendix 2, Table A2-1. Groundwater flow beneath the waste management unit is primarily to the northeast. Estimated horizontal groundwater gradients (i) from the May 2021 groundwater elevations are presented in Table 2. The horizontal gradient (i) calculated for the facility from the data was 0.069. Linear groundwater flow velocities (V) was estimated using the following modified Darcy equation: V = Ki/ne, where: V = average linear velocity; K = hydraulic conductivity; i = horizontal hydraulic gradient; and ne = effective porosity. Hydraulic conductivity (K) was estimated at 3.28 feet/day based on slug tests from a nearby site (John's River Landfill). An effective porosity (ne) of 20% was estimated based on typical values for piedmont aquifers. The estimated linear groundwater flow velocity under the facility is 412 feet/year (Table 2). Because of our conservative estimate of effective porosity, actual groundwater velocities may be significantly less than those calculated. Also, the modified Darcy equation makes the simplified assumptions of a homogeneous and isotropic aquifer, which may yield inaccurate results when applied to heterogeneous and/or anisotropic conditions such as are believed to exist at this site. Migration of groundwater contaminants are expected to follow the general groundwater flow paths and there are no known preferred pathways or barriers to groundwater flow that could significantly affect plume migration or the effectiveness of the groundwater monitoring network to monitoring plume migration. The current groundwater monitoring network remains sufficient for monitoring the groundwater at this facility. 5.0 DATA ANALYSIS The laboratory results from the May 2021 sampling event were received on May 28, 2021, for all monitoring wells (MW-1, MW-2, MW-3, and AMW-1) and surface water monitoring locations (SW-1 and SW-2). All analytical results can be found in Appendix 1. May 2021 Semiannual Water Quality Monitoring Report LaBella Associates Burke County - East Burke Landfill, Permit No. 12-02 August 2021 4 Table 3 summarizes the constituents detected at concentrations above the MDL in all monitoring well and surface water samples for the May 2021 sampling event. Constituents confirmed in exceedance of the appropriate standards are summarized in Table 4. Field Parameters for the May 2021 sampling event are summarized in Table 5. 5.1 Analytical Results and Comparison to Standards 5.1.1 Groundwater Analytical results from monitoring wells were compared directly to the North Carolina Groundwater Standards found in 15A NCAC 02L.0202 (NC2L Standards) or the NC Interim Maximum Allowable Concentrations (IMACs) for constituents with no listed NC2L Standard. Note that estimated concentrations below the Method Reporting Limit (MRL) are not considered exceedances of the standard, even if the estimated value is higher than the standard. Constituents detected in groundwater samples during the May 2021 sampling event are listed in Table 3 and exceedances of the NC21- or IMAC are presented in Table 4. Historically detected constituents in groundwater can be found in Appendix 2, Table A2-2 and historical groundwater field parameters can be found in Appendix 2, Table A2-4. The inorganic constituents detected at quantified concentrations above the MRL during the May 2021 event include: arsenic (MW-2); barium (MW-1, MW-2, MW-3, AMW-1); cobalt (MW-1, MW-2, MW-3); and nickel (MW-2, MW-3). The inorganic constituents detected at quantified concentrations in exceedance of their respective NC21- or IMAC include: arsenic (MW-2); and cobalt (MW-1, MW-2, and MW-3). The organic constituents detected at quantified concentrations above the MRL include: cis-1,2-dichloroethene (MW-2, MW-3, AMW-1); 1,4-dichlorobenzene (MW-2, MW-3); and 1,4-dioxane (MW-2, MW-3). The only organic constituent detected at a quantified concentration in exceedance of the NC21- or IMAC was 1,4-dioxane (MW-3). In general, these detections are consistent with or lower than historical data for the inorganic and organic constituents (Appendix 2, Table A2-2). 5.1.2 Surface Water Analytical results for surface water samples were compared directly to either the Water Supply, Freshwater Aquatic Life, or Fish Consumption Surface Water Standards (whichever was lower) found in 15A NCAC .0213 (NC213 Standards). For metals which have hardness -dependent NC213 Standards, the hardness of the sample collected was used to calculate the NC213 standard. For constituents which have NC213 standards for both chronic and acute exposure, the chronic exposure standard was used. For constituents with no NC213 standards, the results were compared to either the NC In - Stream Target Value (ISTV) or the EPA Nationally Recommended Water Quality Standard (NRWQS). Note that estimated concentrations below the MRL are not considered exceedances of the standard, even if the estimated value is greater than the standard. May 2021 Semiannual Water Quality Monitoring Report LaBella Associates Burke County - East Burke Landfill, Permit No. 12-02 August 2021 5 During the May 2021 sampling event, the constituents detected at quantified concentrations above the MRL include: barium (SW-1, SW-2); beryllium (SW-1); chromium (SW-1, SW-2); cobalt (SW-1, SW-2); copper (SW-1); lead (SW-1, SW-2); nickel (SW-1, SW-2); vanadium (SW-1, SW-2); zinc (SW-1, SW-2); and 1,4-dioxane (SW-1, SW-2). The constituents detected above the NC2B or ISTV were chromium (SW-1); cobalt (SW-1, SW-2); copper (SW-1); lead (SW-1, SW-2); nickel (SW-1); and zinc (SW-1). The constituents detected above the MRL during the June 2021 resampling event include: barium (SW-1, SW-2), cobalt (SW-1), lead (SW-2), and nickel (SW-1). The constituents detected in exceedance with the ISTV or NC2B during the resampling event include: cobalt (SW-1), and lead (SW-2). The May 2021 exceedances for cobalt (SW-1), and lead (SW-2) were confirmed by the resampling event. The exceedances refuted by the resampling event include: chromium (SW-1), cobalt (SW-2), copper (SW-1), lead (SW-1), nickel (SW-1), and zinc (SW-1). Historical surface water data can be found in Appendix 2, Table A2-3. Historical surface water field parameters can be found in Appendix 2, Table A2-5. 6.0 CONCLUSIONS Cobalt was detected in exceedance of the Groundwater Protection Standard in monitoring wells MW- 1, MW-2, and MW-3 during the May 2021 sampling event. Cobalt was also detected in surface water sample SW-1 in exceedance of the ISTV; however, the resampling event refuted the cobalt exceedance in SW-2 and confirmed the cobalt exceedance in SW-1. Arsenic was detected in monitoring well MW-2 in exceedance of the NC2L. 1,4-Dioxane was detected in exceedance of the NC21- in monitoring well MW-3. Chromium, copper, lead, nickel, and zinc were in exceedance of the NC2B in SW-1 during the May 2021 sampling event, but the exceedances were refuted by the resampling event. Lead was also detected in SW-2 during the May 2021 sampling event and the exceedance was confirmed during the resampling event. According to historical groundwater data, inorganic and organic constituents detected above the NC21- or IMAC in groundwater samples collected during the May 2021 sampling event are consistent with previous events. The confirmed surface water exceedance for cobalt in SW-1 was consistent with historical data; however, the confirmed exceedance for lead in SW-2 was new. Based on the results of this groundwater monitoring event, the groundwater monitoring network remains adequate to monitor groundwater at the site. The next semiannual sampling event is tentatively scheduled for November 2021.
