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) 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. Four active groundwater monitoring wells comprise the groundwater monitoring network at the East Burke Landfill. 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 NC Appendix I list of constituents.

Two surface water monitoring points comprise the surface water monitoring program for the East Burke Landfill. The monitoring point locations are shown on Drawing 1. All surface water monitoring points are monitored semiannually for the NC Appendix I list of constituents. Surface Point Classification Monitoring Program SW-1 Compliance .0600 SW-2 Compliance .0600 3.0 FIRST SEMIANNUAL SAMPLING EVENT OF 2016 3.1 Field Work and Visual Inspection In order to detect potential releases of leachate and/or landfill gas migration in a timely manner, a visual inspection program has been implemented at the East Burke Landfill. This inspection program involves field personnel making the following observations:  Observation of stress induced on the biological community (i.e., dead or dying vegetation);  Indications of leachate impact (i.e., seeps, impacted surface water);  Observations of erosion; and  Negative changes around the waste facility. On May 2, 2016, personnel from JOYCE visited the East Burke Landfill to purge and sample monitoring wells MW-1, MW-2, MW-3, and AMW-1. The visual inspection indicated no unusual issues or concerns. Depth-to-water measurements were obtained to the nearest 0.01 foot using an electronic water level indicator for all monitoring wells in the compliance network prior to purging. Monitoring wells were purged and sampled using disposable bailers or a 12-volt pump. Measurements of temperature, pH, specific conductivity, and turbidity were recorded in the site log book prior to purging, after each purge volume, and prior to 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 in the provided laboratory containers either immediately after purging or within 24 First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – East Burke Landfill, Permit No. 12-02 July 2016 3 hours of the final purge volume. Immediately after collection, the samples were placed on ice in a laboratory provided cooler. Field sampling logs are provided in Appendix A. Surface monitoring point SW-1 was not sampled on May 2, 2016, because there was no flowing water to collect. SW-2 was sampled during the May 2, 2016 event. The surface water samples were collected directly from stream flow by lowering the prepared sample containers into the stream flow. Care was taken not to overflow the sample containers (which could lead to preservative loss) and avoid sample-induced turbidity. At the time of sampling, surface water is also measured for temperature, pH, specific conductivity, and turbidity and recorded in the site log book. Immediately after collection, the samples were placed on ice in a laboratory-provided cooler. The field sampling logs are provided in Appendix A. 3.2 Laboratory Analysis and JOYCE Quality Control The May 2016 groundwater and surface water samples were submitted to Pace Analytical Services, Inc. of Huntersville, North Carolina under chain-of-custody control for analysis. JOYCE requested a Level II data report for the final laboratory report. The samples were received by the laboratory on May 5, 2016, 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 JOYCE personnel as part of the May 2016 sampling event. Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling during shipment. The Field Blank was analyzed for the NC Appendix I list compounds while the Trip Blank was analyzed for NC Appendix I VOCs. Upon receipt of the laboratory data package, the data was reviewed by JOYCE personnel for the following:  General typographical errors;  Correct analyses performed and within method specified hold times;  Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike Duplicate, and Laboratory Control Samples;  Blank qualified data (B-flags);  Detections above the NC2L Groundwater Standards, Groundwater Water Protection Standards (GWPS), and/or NC2B Surface Water Standards; and  Detections that are above historical levels. Review of the laboratory reports indicated that the laboratory data package was acceptable. The complete analytical data packages and chains-of-custody are included in Appendix A. First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – East Burke Landfill, Permit No. 12-02 July 2016 4 4.0 DATA ANALYSIS 4.1 Groundwater Analytical Results and Comparison to Standards There were five detections above the NC2L or GWPS for constituents in compliance monitoring wells during the May 2016 monitoring event. Please see Table 3 for the quantified detections from the first semiannual sampling event of 2016. See Table 4 for the detections that were reported above the relevant water quality standard. In general, these detections are consistent with historical data. Historical groundwater data can be found in Appendix B. 4.2 Surface Water Analytical Results and Comparison to Standards There were no constituents detected at quantified concentrations in surface water during the May 2016 sampling event. Additionally, there were no constituents detected at quantified concentrations above the 15A NCAC 2B (NC2B) surface water standards in surface water monitoring points during the May 2016 monitoring event. Historical surface water data can be found in Appendix C. 5.0 HYDROGEOLOGICAL CONDITIONS The surficial aquifer is believed to include the regolith and the underlying fractured metamorphic bedrock. The regolith consists of alluvium, 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. 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 2, 2016 is presented as Drawing 1. The potentiometric surface map depicts groundwater flow primarily toward the northeast. Depth to groundwater was measured in the compliance monitoring wells at the site prior to sampling. The May 2016 and historical groundwater elevations are provided in Table 1. The groundwater elevations were calculated relative to the surveyed measuring point (top of casing) for each monitoring well. Horizontal groundwater gradients along representative flow paths were estimated from the May 2016 groundwater contours shown on Drawing 1 and are summarized in Table 5. Horizontal groundwater gradient across the site is approximately 0.057 ft/ft based on the flow path shown on Drawing 2. Linear groundwater flow velocities for wells screened in saprolite were computed using the modified Darcy equation: V = Ki/n, where V = average linear velocity, K = hydraulic conductivity, i = horizontal hydraulic gradient, and n = effective porosity. The mean of hydraulic conductivities from slug-tests conducted at the Burke County John’s River facility (K = 3.28 ft/day) was used in these calculations, along with an estimated effective porosity of n = 0.20 (20%) for regolith. First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – East Burke Landfill, Permit No. 12-02 July 2016 5 The estimated linear groundwater flow velocity under the facility is 346 feet/year (Table 5). 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. 6.0 CONCLUSION The Burke County East Burke Landfill will continue monitoring groundwater and surface water in accordance with criteria set forth in Rules .0500 and .0600 of the NCSWMR. The next semiannual sampling event is tentatively scheduled for December 2016. 7.0 REFERENCES North Carolina Dept. Environment, Health, and Natural Resources (NCDEHNR), 1995, N.C.
