The 318-acre landfill property is bounded by Lower Creek to the north and east, and the Catawba River to the south. The Catawba River forms Lake Rhodhiss along the southeastern property line (Figure 1). Lake Rhodhiss is a long, narrow lake formed by the Rhodhiss Hydroelectric Dam located approximately 12 miles downstream of the landfill. The John’s River flows into the Catawba River near the southwest corner of the landfill property. A MSW transfer facility is located in the eastern half of the property. A site plan showing all the pertinent features of the facility is provided in Drawing 1. The site has rolling topography with elevations ranging from 975 feet to 1,150 feet above mean sea level (MSL). The central portion is generally gently sloping and contains the higher elevations; relatively steep slopes and significant drainage features are located around the perimeter. The 100-year flood boundary extends onto the landfill property. The adjacent property to the west of the Johns River Waste Management Facility consists of undeveloped, heavily wooded land. Properties within 2,000 feet of the landfill boundary are covered by surface water or are heavily wooded. The C&D-over-MSW waste disposal unit consists of 28 acres in the southwest corner of the landfill property. The municipal solid waste (MSW) landfill began operation in April 1988, but was closed in 1997 to comply with Rule .1627(c)(10)(A) of the NCSWMR, a regulation governing MSW Landfills units that were not designed with a base liner and leachate collection system. Burke County has operated a permitted Construction and Demolition (C&D) disposal area on top of the closed portions of the MSW landfill since 1998. The results of the second semiannual sampling event for the old C&D-over-MSW landfill will be presented in a separate report. A Permit to Construct for Phase 1A was issued in March 2014 and Burke County completed construction of Phase 1A of the C&D landfill expansion in July 2014. A Permit to Operate for Phase 1A was issued by the North Carolina Department of Environment and Natural Resources , now the Department of Environmental Quality (NC DEQ), on August 14, 2014. In accordance with the approved Water Quality Monitoring Plan (WQMP) for the facility (dated August 2012), there are four groundwater monitoring wells designated as compliance wells for Phase 1A: MW- 21(background), MW-20, MW-22S, and MW-38. 1.2 Site Geology The Johns River Waste Management Facility is in close proximity to the Brevard Shear Zone, and is underlain by highly metamorphosed rocks including gneiss and schist, as well as calc- silicate rocks, felsic rocks, and metavolcanic rocks. The dominant rock type at the facility is biotite-muscovite schist, as seen in outcrops, boulders, and rock cores located on site. The structures within limited outcrops indicate that these rocks are complexly-folded, with attitudes that vary from vertical to horizontal. The site regolith is typical of the inner piedmont and 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 2 consists mostly of silty sand, clayey sand, and sandy silt. The regolith is up to 100 feet thick and varies in thickness with topography. An abundance of rounded gravel, cobble, and boulder-sized alluvial deposits are exposed along the banks of the Catawba River, which borders the site. The greatest accumulation of these deposits is along the southwestern site boundary. These river deposits are 40 feet or more above the current river elevation and have been described as ancient river terrace deposits. 1.3 Regulatory Status The following report of groundwater monitoring data from the JRWMF Phase 1A C&D expansion has been prepared in accordance with the North Carolina Solid Waste Management Rules (NCSWMR) 15A NCAC 13B §.0544 (Monitoring Plans and Requirements for C&D Landfill Facilities). The Phase 1A expansion is currently operating under the Detection Monitoring Program. 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program Groundwater monitoring at the JRWMF Phase 1A is performed in accordance with NCSWMR §.0544. Groundwater samples are collected semiannually and analyzed for constituents according to the approved Water Quality Monitoring Plan (WQMP) for the facility dated August 2012. Following is a summary of the compliance monitoring wells. Well ID Date Installed Classification Monitoring Program Total Depth of Well (ft) Lithology of Screened Interval Constituent List MW-20 5-18-95 Compliance Detection 67.0 Saprolite Comp. MW-21 5-18-95 Background Detection 45.0 Saprolite Comp. MW-22s 6-1-96 Compliance Detection 25.0 Saprolite Comp. MW-38 5-09-11 Compliance/ Performance* Detection 71.0 Bedrock Comp., LFG Notes: Comp. = Compliance Parameters: NCSWMR Appendix I and/or Appendix II organics and inorganics plus C&D parameters, as required for routine assessment or detection monitoring. LFG = Landfill Gas Indicators: Dissolved CH4 and dissolved CO2. *MW-38 is also a performance well for the C&D-over-MSW Landfill. The current compliance groundwater monitoring network at the facility consists of one upgradient well (MW-21), and three downgradient wells (MW-20, MW-22S and MW-38). In January 2014, in response to the County’s permit application for the C&D expansion area, the DEQ requested that the County sample several additional wells and/or piezometers in the vicinity of Phases 1 and 2 of the expansion. The County agreed to sample PZ-31, PZ-30S, PZ-34, MW-36(PZ-36), PZ-12, and MW-15S semiannually beginning with the spring 2014 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 3 sampling event. The County also agreed to sample the following other wells/piezometers in the event of GPS exceedances, as follows:  PZ-30D will be added in the event that there are GPS exceedances at PZ-30S;  PZ-35 will be added in the event that there are GPS exceedances at PZ-34;  MW-15D will be added in the event that there are GPS exceedances at MW-15S;  PZ-16S will be added in the event that there are GPS exceedances at PZ-35 or PZ-12; and  PZ-16D will be added in the event that there are GPS exceedances at PZ-16S.  PZ-34 was inadvertently destroyed during the spring of 2014; therefore, PZ-35 is now sampled instead. The additional piezometers/wells are to be sampled for the facility’s COCs (excluding alpha- BHC and beta-BHC). Sampling of the additional piezometers/wells will be conducted for two years (four sampling events), after which the DENR will reevaluate the need for continued sampling of the additional piezometers/wells. 2.2 Surface Water Monitoring Program The current surface water monitoring points are SMP-5, SMP-6, and SMP-7. Surface water monitoring point SMP-5 (located at the southwestern property line) and SMP-6 (located at the southeastern property line) are both located downstream from existing sediment basins. Surface water monitoring point SMP-7 is located downstream from the Phase 1A expansion area. The surface water monitoring program is designed to monitor for possible impacts from both the C&D over MSW Landfill and the Phase 1A C&D Landfill; surface water samples are analyzed for the NCSWMR Appendix I list of constituents plus detected Appendix II constituents during both semiannual events. Surface Point Classification Monitoring Program Location SMP-5 Compliance Surface Water Creek on west side of landfill, downstream of sediment basin. SMP-6 Compliance Surface Water Creek on east side of landfill, downstream of sediment basin. SMP-7 Compliance Surface Water Creek southeast of Phase 1A and east of sediment basin SB-2A. Downstream of PZ-12. 3.0 FIRST SEMIANNUAL SAMPLING EVENT OF 2016 3.1 Field Work 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 John’s River Waste Management Facility. This inspection program involves field personnel making the following observations: 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 4  Indications of stress on the biological community (e.g., dead or dying vegetation);  Indications of leachate impact (e.g., seeps, impacted surface water);  Observations of erosion;  Condition of monitoring wells; and  Negative changes around the waste facility. On May 3-4, 2016, personnel from JOYCE visited John’s River Waste Management Facility to purge and sample monitoring wells MW-20, MW-21, MW-22S, and MW-38. Additional wells/piezometers MW-15S, PZ-12, PZ-30S, PZ-31, PZ-35, and PZ-36 were also sampled. Surface monitoring points SMP-5, SMP-6, and SMP-7 were also sampled during the May 2016 event. The usual inspections 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. Table 1 presents current and historical groundwater elevation data. Monitoring wells were purged and sampled using disposable bailers. Measurements of temperature, pH, specific conductivity, and turbidity were recorded in the site log book as well as on field data logs prior to purging, after each purge volume, and during sampling. Field data logs for the June 2016 event are provided in Appendix A, and the field parameters are summarized in Table 2. Laboratory-supplied containers were prepared and labeled (either by the laboratory or in the field, as indicated) 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 dispensed directly from the disposable bailers into the provided laboratory containers either immediately after purging or within 24 hours of the final purge volume. Immediately after collection, the samples were placed in a laboratory-provided cooler and chilled with ice. Surface water samples were collected directly from stream flow by lowering the prepared sample containers into the stream flow. Care was taken not the overflow the sample containers (which could lead to preservative loss) and avoid sample-induced turbidity. At the time of sampling, surface water was also measured for temperature, pH, specific conductivity, and turbidity and recorded in the site log book. After sample collection, the samples were placed in a laboratory provided cooler and chilled on ice. Field data logs are provided in Appendix A, and the field parameters are summarized in Table 2. 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 5 3.2 Laboratory Analysis and JOYCE Quality Control The First Semiannual (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. The groundwater samples were analyzed for the NC Appendix I list of constituents, plus additional required C&D parameters. Surface water samples were analyzed for the NC Appendix I list of constituents (plus detected Appendix II constituents form the old C&D-over- MSW landfill) during both semiannual events. JOYCE 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 required hold times. In addition to samples collected for compliance monitoring at the John’s River Waste Management Facility, a Field Blank was collected by JOYCE personnel as part of the June 2016 sampling event. Also, a Trip Blank prepared by the laboratory accompanied the volatile sampling containers from and to the laboratory. The Field Blank was analyzed for the NC Appendix I, plus previously detected Appendix II list of constituents, plus iron, manganese and tetrahydrofuran, and the Trip Blank was analyzed for Appendix I list of constituents plus additional detected Appendix II volatile organic compounds and tetrahydrofuran. Upon receipt of the laboratory data package, JOYCE personnel reviewed the data package for quality assurance/quality control (QA/QC) purposes and for possible regulatory issues. If any QA/QC or regulatory issues were found, the laboratory would be contacted to resolve the issue, and a resampling event might be scheduled, if needed. The laboratory analytical packages can be found in Appendix B of this report. The data package was reviewed 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 exceeding the North Carolina 15A NCAC 2L .0202 Groundwater Standards (NC2L), DENR-SWS Groundwater Water Protection Standards (GWPS), and North Carolina 15A NCAC 2B Surface Water Standards (NC2B); and  Detections that are above historical levels. 4.0 ANALYTICAL RESULTS AND STATISTICAL ANALYSIS The constituents with quantified detections above the SWSL in one or more compliance monitoring wells are presented in Table 3 and the constituents with exceedances of the NC 2L Standards or GWPS in one or more compliance monitoring wells are presented in Table 4. The constituents with quantified detections above the SWSL in one or more of the additional wells/piezometers are presented in Table 5 and the constituents with exceedances of the NC 2L Standards or GWPS in one or more additional wells/piezometers are presented in Table 6. The complete laboratory reports and chains of custody are included in Appendix B. Historical data are presented in Appendices D, E, and F. 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 6 4.1 Analytical Results for Inorganic Constituents Four inorganic constituents were detected above the NC 2L/GWPS in one or more monitoring wells during the May 2016 sampling event. The constituents were Chromium, Cobalt, plus the C&DLF parameters iron and manganese. Chromium was detected above the NC 2L Standard in MW-20 for the first time. Vanadium was also detected above the NC 2L Standards in MW-21 for the first time. Iron was reported above the NC 2L Standard in MW-20, MW-22S and MW- 38; and manganese was reported above the NC 2L Standard in MW-20, MW-21, and MW-38. However, an ASD was approved for iron and manganese by DENR for the Johns River facility on April 12, 2012. In general, the detections and concentrations are consistent with historical data and below calculated background values (see Section 4.3.2). 4.2 Analytical Results for Organic Constituents Three organic constituents, benzene, 1,1-dichloroethane, and 1,4-dichlorobenzene, as well as vinyl chloride, were detected above the NC 2L Standards in compliance monitoring well MW-38 during the May 2016 sampling event. In addition, results from the additional wells/piezometers indicated NC 2L exceedances of benzene and tetrachloroethylene in MW-15S, and of benzene, 1,4-dichlorobenzene, and tetrachloroethene in MW-36. The results for MW-15S and MW-36 were consistent with historical data, but the vinyl chloride in MW-38 was not consistent. A verification sample for vinyl chloride in MW-38 was performed on June 9, 2016; and, the results did not confirm the vinyl chloride exceedance or detection. No other exceedances were noted in any of the other wells/piezometers. The exceedances noted in MW-15S, MW-36, and MW-38 are believed to be due to landfill gas migration from the C&D-over-MSW Landfill and are being addressed in the Corrective Action Plan for that landfill. In general, the detections and concentrations are consistent with historical data. 4.3 Statistical Analyses 4.3.1 Statistical Methods and Background MW-9 was the facility background well from 1994 until May 2005, when it was abandoned. MW-17 was the facility background well from May 1999 until June 2011. Both MW-9 and MW-17 were sampled between May 1999 and May 2005. Due to gas related impacts to MW-17, MW-20 became the facility background well in December 2010. Both MW-17 and MW-20 were sampled between December 2010 and June 2011. With the opening of Phase 1A of the C&D expansion in August 2014, MW-21 (formerly PZ-1) became the facility background well and MW-20 became a compliance well for Phase 1A. Facility background data used to evaluate the May 2016 groundwater monitoring data include all data collected for wells MW-9, MW-17, and MW-20 from September 1994 through the May 2015 event, plus the May 2015 to the current results from MW-21. The background data for inorganic constituents were evaluated using the Shapiro-Wilk Test, Parametric Prediction Limits, Parametric Tolerance Intervals, Aitchison’s Adjustment, Non- 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 7 Parametric Prediction Limits, and/or Poisson Prediction Limits as appropriate. Background data, tests for normality, outliers, Aitchison’s adjustment, tolerance interval, or prediction limits are used, as appropriate based on the background data. The statistical test by which downgradient data are compared to facility background data is based upon the nature of the data and the number of data values that are less than the laboratory limit of detection. All statistical tests are evaluated at the 0.05 level of significance, 95% confidence level, and are conducted as one-tailed tests. 4.3.2 Inorganic Constituents The inorganic constituents detected at quantifiable concentrations (excluding blank-qualified data) above the North Carolina SWSL in downgradient monitoring wells in the May 2016 sampling event were barium, cobalt, chromium, vanadium, zinc, iron, and manganese, as well as the additional C&DLF parameters. The May 2016 results represent the first time chromium detection in MW-20 and vanadium detection in MW-21 were reported above the NC 2L for Phase 1A; however, the results were below calculated background values. Iron and manganese were addressed in an ASD approved by DENR in April 2012. Details of the statistical analyses of background data can be found in Appendix C. A summary of the statistical analyses is given below and in Table 7. Constituent Data Distribution Statistical Method used to Establish Background Background Concentration NC2L or GWPS* Cobalt 46% ND Aitchison’s Adjusted Parametric Prediction/ Upper Tolerance Limit 93.6 1 µg/L* Chromium 68% ND Non-parametric Prediction Limit 290 10 µg/L Vanadium 64% ND Non-parametric Prediction Limit 630 0.3 µg/L* ND = Not Detected (truncated data). 4.4 Analytical Results for Surface Water Copper and Zinc were detected in SMP-7 at quantified concentrations. Copper was above the 15A NC AC 02B Surface Water Standards (NC2B) during the May 4, 2016 event, so a verification sample was collected for copper and total water hardness on May 17, 2016. The results of the verification sample did not confirm the copper detection. In general, the 2016 first semiannual surface water results are consistent with historical data. Current and historical surface water data can be found in Appendix F. 5.0 HYDROGEOLOGICAL CONDITIONS Based on outcrop and drilling information, the water table appears to occur within regolith everywhere across the site. This regolith consists of alluvium, residual soils, saprolite, and variably fractured and weathered layered metamorphic rock. Inspection of drill cuttings and site outcrops indicates that water in the regolith is transmitted largely through fractures. 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 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 8 properties. Along the low-lying areas of the Catawba River and its tributaries, the water table occurs within surficial alluvial deposits overlying the residual soils and weathered bedrock. Groundwater discharges into creeks to the east and west of the landfill and to the Catawba River to the south. A groundwater potentiometric surface map, developed from static water level data obtained in May 2016, is presented as Drawing 1. The potentiometric surface map depicts groundwater flow primarily to the south. 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 8. Horizontal gradients across the site ranged from 0.0360 to 0.0602 ft/ft, with an average of approximately 0.0503 ft/ft. This is consistent with previous estimates. 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 average of hydraulic conductivities from slug-tests conducted at the facility (K = 3.28 ft/day) was used in these calculations, along with an effective porosity of n = 0.40 (40%) based on laboratory porosities for soil samples from the facility. The estimated linear groundwater flow velocity under the facility ranged from 108-180 feet/year, with an average flow velocity of approximately 142.4 feet/year (Table 8). 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. The groundwater flow direction and rate have shown no significant seasonal variations over several years of monitoring. The groundwater flow regime on this site is well constrained and predictable. 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 There were several organic constituents detected above the NC 2L Groundwater Standards at the Johns River Landfill during the May 2016 sampling event. A vinyl chloride detection above the NC 2L was initially reported in MW-38 for the first time. A verification sample for vinyl chloride in MW-38 was collected on June 9, 2016, and the analytical results did not confirm the initial detection. The other organic detections reported in excess of NC 2L Standards in MW-38 1st Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Burke County – Johns River Landfill, Phase 1A, Permit No. 12-03 August 2016 9 and the additional wells and piezometers are generally consistent with previous sampling events, attributed to the old C&D-over-MSW Landfill covered by a separate report, and are being addressed by the Corrective Action Plan for the facility. Inorganic detections included the first time chromium detection in MW-20 and a vanadium detection in MW-21, both of which were reported above the NC 2L Standard; however, the detections were not above the calculated statistical background concentrations (see Section 4.3.2); therefore, we request that the background be considered the Groundwater Protection Standards (GPS) for chromium and vanadium per rule .1634(g)(5) of the NCSWMR. An ASD was approved for iron and manganese by DEQ (formerly DENR) on April 12, 2012. Copper was detected above the NC 2B Surface Water Standards in SMP-7 during the May 3-4, 2016 sampling event, but the copper detection was refuted in a May 17, 2016 verification sampling event for SMP-7. Surface water monitoring is consistent with previous monitoring events. The groundwater flow regime is consistent with previous events and the groundwater monitoring network remains adequate to monitor the site. Based on analytical results from the May 2016 sampling event, Phase 1A of the John’s River Landfill will remain in Detection Monitoring. The next semiannual sampling event is scheduled for the second quarter of 2016. 7.0 REFERENCES Hinchee, R.E., A. Leeson, L. Semprini, and S.K. Ong. 1994.
