The existing landfill was initially permitted in the early 1970’s by the state of North Carolina as a private industrial landfill used to dispose of residue from the automobile shredder under Permit Number 34-17, and was owned and operated by Atlantic Scrap and Processing, LLC. The landfill received automotive shredder residue (ASR, or “fluff”) consisting of plastic, glass, rubber, foam, fabric, etc., that was generated by the on-site operations. The landfill stopped receiving waste and was closed in the mid-1990s. In 2005, the facility received a permit for a mining operation to recover additional metal from the ASR waste. Currently the facility is operating a landfill mining operation under Permit Number 34-20. The OmniSource Landfill includes approximately 14 acres located within OmniSource-Southeast property located at 1426 West Mountain Street in Kernersville, North Carolina. Access to the landfill area is limited from the southern end by means of the fenced scrap processing area and from other directions by berms, topography, and the side-slopes of the landfill. The site location is shown in Figure 1 on an excerpt from the 7.5-minute USGS topographic map for the area. 1.2 Site Geology and Hydrogeology The OmniSource Landfill is located in the Piedmont physiographic providence of North Carolina and is underlain by intrusive granitic rocks of Pennsylvanian to Permian age which are part of the Carolina Slate Belt Geologic Unit. The groundwater level measurements taken on April 12, 2017 were used to construct the groundwater surface contours shown in Drawing 1. Historical static water levels are provided in Table 1. Groundwater flow at the site is toward the northeast. Using the hydraulic gradients along the flow paths shown on Drawing 1, the linear flow velocity (V) was estimated using the modified Darcy equation: V=Ki/n. The average hydraulic gradient (i) based on the flow paths shown on Drawing 1 is 0.0646 ft/ft. An effective porosity (n) of 30% was estimated based on typical values for piedmont aquifers. Hydraulic conductivity (K) of 1.73 ft/day was estimated from slug testing done by JOYCE at nearby site is Kernersville, NC in November of 2013. The calculated groundwater flow rate averages approximately 136 ft/yr. A summary of the hydraulic gradients and linear flow velocities is provided in Table 2. ______________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering OmniSource Kernersville Landfill, Permit No. 34-20 August 2017 2 1.3 Regulatory Status The OmniSource Landfill is currently monitoring groundwater in accordance with criteria set forth in Title 15A Subchapter 13B .0500 of the North Carolina Solid Waste Management Rules (NCSWMR) as well as the approved sampling and analysis plan dated October 2011. 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program The original groundwater monitoring network consisted of 4 monitoring wells installed in 1989; MW-1, MW-2, MW-3 and MW-4. In 2001, MW-4R was installed to replace MW-4 and MW-1R replaced MW-1 to further expand scrap metal processing activities. Monitoring wells MW-2, MW-3, MW-4, and MW-4R were destroyed during mining operations. Replacement wells MW-12, MW-13, and MW-14 were installed in 2012. The current groundwater compliance monitoring network consists of four monitoring wells, including one upgradient well (MW-1R) and three downgradient wells (MW-12, MW-13, and MW-14). These wells are summarized below, along with their current monitoring program status. The locations of the monitoring wells are shown on Drawing 1. Monitoring Well Classification Monitoring Program Total Depth from TOC (ft) MW-1R Upgradient Detection 104.73 MW-12 Downgradient Detection 28.82 MW-13 Downgradient Detection 26.15 MW-14 Downgradient Detection 33.68 TOC = Top of casing. Groundwater samples are collected semiannually during the second and fourth quarters. Samples are analyzed for all constituents listed in the NCSWMR Appendix I during the first and second semiannual events. 2.2 Surface Water Monitoring Program Surface water at the OmniSource Kernersville Landfill is monitored semiannually in conjunction with the groundwater sampling events. Samples are collected from four surface water monitoring points (SW-1, SW-2, SW-3 and SW-4). The locations of the surface water monitoring points are shown on Drawing 1. Surface water samples are collected and analyzed for the NCSWMR Appendix I list of constituents during both semiannual monitoring events. The results are compared to the 15A NCAC 2B (NC2B) Surface Water Standards in a value-to-value comparison. These surface water monitoring points are summarized below, along with their current monitoring program status. ______________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering OmniSource Kernersville Landfill, Permit No. 34-20 August 2017 3 Surface Point Classification Monitoring Program SW-1 Upstream/Compliance Surface Water SW-2 Downstream/Compliance Surface Water SW-3 Downstream/Compliance Surface Water SW-4 Downstream/Compliance Surface Water 3.0 FIRST SEMIANNUAL SAMPLING EVENT OF 2017 3.1 Field Work and Visual Inspection In order to detect potential releases of leachate in a timely manner, a visual inspection program has been implemented at the OmniSource Kernersville Landfill. This inspection program involves field personnel making the following observations:  Observation of stress induced on the biological community (e.g., dead or dying vegetation);  Indications of leachate impact (e.g., seeps, impacted surface water);  Observations of erosion; and  Negative changes around the waste facility. On April 12, 2017, Joyce Engineering (JOYCE) personnel visited the facility to purge and sample the facility’s monitoring wells MW-1R, MW-12, MW-13, and MW-14. Prior to purging, the depth to static water level was measured for all monitoring wells with an electronic water level indicator, accurate to 0.01 foot. Monitoring wells were purged and sampled, in accordance with the October 2011 Sampling & Analysis Plan, using either a 12-volt submersible pump or disposable bailer. Measurements of temperature, pH, specific conductivity, 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 12-volt pump or disposable bailers in the provided laboratory containers either immediately after purging or within 24 hours of the final purge volume. Immediately after collection, the samples were ______________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering OmniSource Kernersville Landfill, Permit No. 34-20 August 2017 4 placed in a laboratory-provided cooler and chilled on ice. Field data logs are provided in Appendix A. Surface water samples from SW-1, SW-2, SW-3 and SW-4 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 to avoid sampling- induced turbidity. At the time of sampling, surface water was also measured for temperature, pH, specific conductivity, and turbidity. After sample collection, the samples were placed in a laboratory-provided cooler and chilled on ice. Field data logs are provided in Appendix A. 3.2 Laboratory Analysis and Quality Control The April 12, 2017, groundwater and surface water samples were submitted to Pace Analytical Services of Huntersville, North Carolina. The samples were analyzed for the NCSWMR Appendix I constituents. JOYCE requested a Level II data report for the final laboratory report. The samples were received by the laboratory on April 13, 2017, in good condition, properly preserved, and within analysis hold times. In addition to samples collected for compliance monitoring at the OmniSource Kernersville Landfill, a Field Blank was collected by JOYCE personnel as part of the April 2017 sampling event. Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling containers during shipment to and from the laboratory. The April 2017 Field Blank was analyzed for the NCSWMR Appendix I constituents while the April 2017 Trip Blank was analyzed for the NCSWMR Appendix I volatile organics only. 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 groundwater and surface water standards; and  Detections that are above historical levels. 4.0 DATA ANALYSIS 4.1 Groundwater Data Analysis and Comparisons to Standards The Laboratory Analytical Report from the April 2017 sampling event was received April 24, 2017, from Pace Analytical and is included in Appendix B with the chains-of-custody. Constituents that were detected at quantified concentrations above the North Carolina ______________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering OmniSource Kernersville Landfill, Permit No. 34-20 August 2017 5 Department of Environmental Quality (NCDEQ) Solid Waste Section Limits (SWSL) in groundwater during the April 2017 sampling event are summarized in Table 3. Analytical results from monitoring wells were compared directly to the North Carolina Groundwater Standards found in 15A NCAC 02L.0202 (NC2L Standards) or the NCDEQ Solid Waste Section Groundwater Protection Standards (GWPS) for constituents with no listed NC2L standard. Constituents in exceedance of the appropriate standards are summarized in Table 4. Field parameter data for the April 2017 sampling event are summarized in Table 5. Inorganic constituents barium beryllium copper and zinc were detected at quantified concentrations above the SWSL in one or more monitoring wells. No organic constituents were detected at quantified concentrations above the SWSL. No inorganic or organic constituents were detected above the NC2L or GWPS. 4.2 Surface Water Data Analysis and Comparisons to Standards Analytical results for surface water samples were compared directly to either the Freshwater Aquatic Surface Water Standards or Human Health Surface Water Standards (whichever is lower) found in 15A NCAC 02B (NC2B Standards). Constituents in exceedance of the appropriate standards are summarized in Table 4. Field parameter data for the April 2017 sampling event are summarized in Table 5. The results for the upstream surface water sample, SW-1, indicated one inorganic constituent with a quantified concentration above the SWSL during the April 2017 sampling event. Zinc was quantified at a concentration of 54.8 µg/L in SW-1, which is above the respective NC2B standard for freshwater aquatic life (FAL), which is 36 µg/L. In addition, three organic constituents, tetrachloroethene, Carbon Tetrachloride and Chloroform were detected above the SWSL in SW-1. Tetrachloroethene was found at a concentration of 5.2 µg/L, which exceeds the NC2B human health standard, for (3.3 µg/L). Since surface water sampling point SW-1 is upstream of the OmniSource landfill, it is highly unlikely that the constituents detected in SW-1 are due to a release from the landfill. Zinc was also detected at qualified concentrations exceeding the NC2B standard at 36.8 µg/L. SW-3 is the surface point located just downstream from SW-1 on the property. The most likely source of detected constituents in SW-1 and SW-3 is the former Destructo-Chemway/CaroLawn property, which is directly upstream of the SW-1 location. This property is a NC Inactive Hazardous Site, which was the source of a major spill of hazardous material, including chlorinated solvents, in 1977. The spill flowed down the creek where SW-1 is located and eventually contaminated the Kernersville Reservoir. We believe the organic constituents and some of the inorganic constituents detected in SW-1 are residuals from this incident. Zinc was the only constituent detected in surface water samples SW-2 and SW-4 at quantified concentrations above its respective SWSL during the April 2017 sampling event. No constituent detected was higher than the NC2B standard for freshwater aquatic life. The April 2017 result is not higher than historical values for zinc in SW-2 and it is lower than the concentration of zinc detected in the upstream sample, SW-1, which had a zinc concentration of 54.8 µg/L. The fact ______________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering OmniSource Kernersville Landfill, Permit No. 34-20 August 2017 6 that zinc concentrations consistently decrease moving progressively downstream from SW-1 supports the contention that the origin of the zinc is the CaroLawn site. Historical surface water data can be found in Table 7. 5.0 CONCLUSIONS There were no exceedances of groundwater protection standards in any of the monitoring wells during the April 2017 sampling event. The facility should remain in detection monitoring. The next semiannual sampling event is tentatively scheduled for October 2017. 6.0 REFERENCES Brown, Philip M., Chief Geologist, 1985, Geologic Map of North Carolina, The North Carolina Geologic Survey, scale 1:500,000.
