The Jackson County Solid Waste Department maintains a closed Municipal Solid Waste Landfill (MSWLF) located approximately 0.75 miles west of Dillsboro, North Carolina, on the northeast side of Old Dillsboro Road (Old U.S. Highway 74; Figure 1). Water quality monitoring at the landfill is governed by the North Carolina Department of Environmental Quality (DEQ), Division of Waste Management (DWM), Solid Waste Section (SWS), under Permit No. 50-02 issued to Jackson County. The landfill permit requires semiannual monitoring of groundwater and surface water quality. Over time, groundwater quality monitoring indicated persistent low-level concentrations of constituents that exceed groundwater standards. In response to the continued exceedances of analyzed constituents, an Assessment of Corrective Measures (ACM) was completed and a Corrective Action Plan (CAP) was implemented. The implemented remedy includes the extraction of leachate through dedicated submersible pumps installed within the landfill gas extraction wells and disposal of the leachate into the Tuckaseigee Water & Sewer Authority (TWSA) collection system. In addition to leachate extraction, groundwater natural attenuation parameters are monitored and natural attenuation processes are evaluated. The remedy was implemented in a phased approach with full implementation occurring on September 6, 2013. This report serves as the second semiannual water quality monitoring report for 2016 and as the eleventh report following approval of the CAP. This report provides an evaluation of groundwater and surface water quality. The water quality monitoring network is presented on Figure 2. The generalized groundwater flow direction in the upper parts of the underlying aquifer system (Figure 3) is also provided in this report. In addition to groundwater and surface water monitoring, this report includes volatile organic compound (VOC) analysis of the extracted leachate. The water samples are collected from selected monitoring points during the spring and fall of each year and are analyzed for the following (Table 1):  Appendix II VOCs  Appendix II SVOCs  Appendix II Metals  Polychlorinated Biphenyls (PCBs)  Appendix II Herbicides  Monitored natural attenuation (MNA) parameters: alkalinity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), chloride, carbon dioxide, cyanide, ethane, ethene, Fall 2016 Semiannual Water Quality Monitoring Report 2 February 2017 hydrogen, ferrous iron, methane, nitrate, sulfate, sulfide, total organic carbon (TOC), and volatile fatty acids. The fall 2016 sampling event was performed on October 11 and 12, 2016, and is being reported in accordance with requirements stipulated in the DEQ Solid Waste Management Rules codified under Title 15A Subchapter 13B of the North Carolina Administrative Code (15A North Carolina Administrative Code [NCAC] 13B). Fall 2016 Semiannual Water Quality Monitoring Report 3 February 2017 2 Semiannual Monitoring 2.1 Groundwater, Surface Water, and Leachate Sampling The closed MSWLF monitoring wells (MW-01, MW-02, MW-03, MW-04, MW-05R, MW-06, and MW- 07), surface water sample locations (SW-01 and SW-02), one leachate sample location (LT-01), and one domestic water well (DW-01) were sampled on October 11 and 12, 2016 by Altamont Environmental, Inc. (Altamont), which became Anchor QEA on December 29, 2016. Static groundwater level measurements and all field parameter data are included on the well sampling logs presented in Appendix A. The full suite of groundwater and surface water laboratory analytical results is presented in the laboratory analysis reports in Appendix B. Domestic well DW-02 could not be sampled during this event. Power to the well’s pump was turned off and the homeowner was not available. The monitoring wells, surface water sample locations, domestic wells, and leachate sample locations are depicted on Figure 2. 2.1.1 Monitoring Well Purging and Sampling Methods Prior to sampling the monitoring wells, the static water level was gauged in each well and an initial round of field parameters consisting of pH, specific conductivity, dissolved oxygen (DO), turbidity, temperature, and oxidation reduction potential (ORP) were measured. Altamont personnel used either low-flow techniques or disposable bailers to purge the monitoring wells and collect groundwater samples. Total depth, condition of the casing, and the groundwater recharge rate determined the purging and sample collection method employed at each monitoring well. 2.1.1.1 Monitoring Wells Monitoring wells MW-03, MW-04, MW-06, and MW-07 were purged using low-flow techniques in accordance with the procedures described in the United States Environmental Protection Agency’s (EPA’s) Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures (EPA 1996). During purging, the pH, specific conductivity, DO, ORP, turbidity, and temperature (field parameters) were measured and recorded approximately every 3 minutes. Well purging continued until these parameters generally stabilized for three consecutive readings. The required stabilization criteria were as follows:  pH values within +/- 0.1 Standard Unit (SU)  Specific conductivity values within +/- 5 percent  Temperature, DO, and turbidity values within +/- 10 percent  ORP values within +/- 10 millivolts Fall 2016 Semiannual Water Quality Monitoring Report 4 February 2017 Once the parameters had stabilized, a groundwater sample was collected by a technician wearing a new pair of nitrile gloves using laboratory-supplied sample containers. Monitoring well MW-01 was purged and sampled using a new, disposable polyethylene bailer. The well was purged of three successive well volumes prior to sample collection. During purging, a round of field parameters was measured and recorded at the start of purging and after each consecutive well volume was purged. After the third consecutive well volume was purged, a groundwater sample was collected. MW-02 and MW-05R were purged dry with a disposable bailer on October 11, 2016 and the groundwater sample was collected on the following day after the well had recharged. All field parameter data are shown on the well sampling logs, included in Appendix A. 2.1.2 Surface Water Sampling Methods Surface water samples SW-01 and SW-02 were collected on October 12, 2016, at designated locations from the Tuckasegee River, which is adjacent to and southwest of the landfill. Surface water sampling location SW-01 is representative of surface water quality upstream of the landfill; surface water sampling location SW-02 is representative of surface water quality downstream from the landfill. One round of field parameters was measured and recorded at each surface-water sampling location prior to collecting the sample (Appendix A). The surface water samples were collected in laboratory-provided sample containers by a technician wearing a new pair of nitrile gloves. 2.1.3 Leachate Sampling Methods Dedicated bottom-loading, air-powered pumps, air pressure lines, and a leachate force main collection system are installed at the landfill. Pumps are installed in landfill gas extraction wells EW-1R, EW-2R, EW-3R, EW-4, EW-5, EW-6, EW-7, EW-8, EW-9, and EW-10. The gas extraction well locations are presented on Figure 2. The leachate is pumped from the wells into a flow equalization tank, which is connected to the TWSA wastewater collection system. The flow equalization tank is situated to the northeast of the landfill adjacent to the existing landfill gas flare. A grab sample of leachate (LT-01) was collected by taking a sample as the leachate entered the flow equalization tank. One round of field parameters was measured and recorded after collecting the sample (Appendix A). 2.2 Sample Handling, Documentation, and Analysis Field parameters and additional observations pertaining to the closed MSWLF sampling locations are provided on sampling logs (Appendix A). Following sample collection, each groundwater, surface water, and leachate sample was immediately placed on ice in a sample cooler for transport to Prism Fall 2016 Semiannual Water Quality Monitoring Report 5 February 2017 Laboratory, a North Carolina-certified laboratory located in Charlotte, NC. The groundwater samples collected from the monitoring wells were analyzed for the following parameters:  Appendix II Metals using EPA Approved Methods (EPA Method) 6020B and 7470A  Appendix II VOCs using EPA Method 8260B  Appendix II semivolatile organic compounds (SVOCs) using EPA Method 8270D  Appendix II Herbicides using EPA Method 8151A  PCBs using EPA Method 8082A  MNA Parameters: ‒ Alkalinity using Standard Method (SM) 2320B ‒ BOD (5-Day) using SM 5210B ‒ Carbon dioxide, hydrogen, ethane, ethene, and methane using Analytical Method (AM) AM20GAX ‒ COD using SM 5220D ‒ Chloride, nitrate, and sulfate using EPA Approved Method 9056A ‒ Cyanide using SM 4500-CN E ‒ Ferrous iron using SM 3500-Fe D ‒ Sulfide using SM 4500-S F ‒ TOC using SM 9060A ‒ Volatile fatty acids using AM23G The surface water samples were analyzed for Appendix II parameters and PCBs (as listed above). The leachate sample was analyzed for Appendix I VOC parameters only. The domestic well sample (DW-01) was analyzed for Appendix I VOCs by EPA Method 524.2. Proper chain-of-custody documentation procedures were followed during collection and transportation of each sample (Appendix B). Four trip blank samples for quality control/quality assurance purposes were included in the sample coolers and analyzed for Appendix I VOCs. The reports of laboratory analysis are provided in Appendix B. Laboratory analyses performed on the samples are summarized in Table 1. Fall 2016 Semiannual Water Quality Monitoring Report 6 February 2017 3 Findings 3.1 Analytical Results The laboratory analytical results and field parameter data for the groundwater samples (from monitoring wells MW-01 through MW-07), surface water samples (SW-01 and SW-02), and leachate sample (LT-01) collected at the landfill are included in Appendices A and B in hard copy and also submitted separately to the DEQ DWM SWS in in the Electronic Data Deliverable (EDD) format per their guidelines (most recently updated on May 5, 2010). As stipulated in the SWS documents referenced above, all laboratory analytical results were reported and appropriately qualified as follows:  Non-detections: Non-detections (non-detects), are values reported by the laboratory as below method detection limits (MDLs). They are tabulated on Table 2 and are qualified with the “U” qualifier. The MDL is the minimum concentration of a substance that can be measured and reported by a laboratory with 99 percent confidence that the constituent concentration is greater than zero.  Solid Waste Section Limits: All detections (values above the MDL) were compared to constituent-specific Solid Waste Section Limits (SWSLs) established by DEQ. The SWSL is defined as the lowest concentration of a constituent in a sample that can be quantitatively determined with suitable precision and accuracy. A “J” qualifier is used by the laboratory for parameters that are detected at estimated concentrations greater than the MDL but less than the laboratory’s method reporting limit (MRL). The MRL is the minimum concentration of a target analyte that can be accurately determined by the referenced method.  Estimated or “J” Qualified: If the reported concentration is greater than the laboratory MDL and MRL but less than the SWSL, the analytical result is qualified as estimated, and is flagged with a “J” qualifier (italicized J-flag) by Anchor QEA, per SWS reporting requirements. In addition to non-detects, detected concentrations of constituents below the applicable SWSLs are included in Table 2.  Exceeds a 2L Standard: Detected concentrations of constituents in groundwater samples were compared to applicable North Carolina groundwater quality standards. For most constituents, this standard is the 2L standard, defined in 15A NCAC 2L.0202. Detected concentrations of analytes in groundwater with no established 2L standard were compared either to the interim maximum allowable concentrations (IMACs) for Class GA and GSA groundwater (in accordance with 15A NCAC 02L .0202 [c]) or Groundwater Protection Standards (GWPS), pursuant to 15A NCAC 13B.1634.  Exceeds a 2B Standard: Detections of analytes in surface-water samples were compared to the surface-water quality standards described in 15A NCAC 2B (2B standards). Fall 2016 Semiannual Water Quality Monitoring Report 7 February 2017 Table 2 presents the summary of detected constituents and outlines concentrations of analytes that were above applicable SWSLs, as well as detected analytes that exceeded their respective 2L standard, IMAC, GWPS, or 2B standard. 3.1.1 Groundwater Measured field parameters and analytical results of groundwater samples collected from the monitoring wells are discussed in the following sections. 3.1.1.1 Field Parameters During groundwater sampling on October 11 and 12, 2016, pH readings were obtained. The pH readings obtained from samples collected from wells MW-01, MW-03, MW-04, MW-05R, MW-06, and MW-07 were below 6.5 SU, thus outside the acceptable pH range of 6.5 to 8.5 SU specified in 15A NCAC 02L .0202[c] (Table 2). The recorded pH readings are consistent with historical data. The highest turbidity (recorded as out of range of the turbidimeter) was measured in the groundwater sample collected from well MW-05R. The lowest turbidity was measured (3.42 NTU) in the groundwater sample collected from well MW-04. 3.1.1.2 Appendix II Metals Five metals (cadmium, chromium, cobalt, thallium, and vanadium) were detected at concentrations above their respective water quality standards in the groundwater samples collected from one or more of the monitoring wells during the fall 2016 water quality monitoring event. Cadmium and chromium exceeded their respective 2L standard, the other three metals exceeded their IMACs. Cadmium was detected in monitoring well MW-01 at a concentration of 2.2 micrograms per liter (µg/L), which exceeded its 2L standard of 2 µg/L. Cadmium concentrations in the samples collected from MW-01 have exceeded the 2L standard during several prior sampling events, according to historical data. Cadmium has historically been detected in all of the monitoring wells on-Site, but below the 2L standard. Chromium was detected in monitoring well MW-05R at a concentration of 14 µg/L, which exceeded its 2L standard of 10 µg/L. According to historical data, chromium concentrations have exceeded the 2L standard in the samples collected from this monitoring well during several prior sampling events. Cobalt was detected above its IMAC in all seven collected groundwater samples. Concentrations of cobalt in these samples ranged from 1.2 J µg/L (MW-07) to 160 µg/L (MW-01). Historically, cobalt has been present above its water quality standard in groundwater samples from all seven monitoring wells. Fall 2016 Semiannual Water Quality Monitoring Report 8 February 2017 Thallium was detected in all of the groundwater samples collected from the landfill. Three of the groundwater samples contained concentrations that were above the IMAC water quality standard of 0.2 µg/L. Concentrations of thallium in these samples ranged from 0.40 J µg/L (MW-05R) to 1.7 J µg/L (MW-01). Historically, thallium has been present above its water quality standard in the samples collected from groundwater monitoring wells MW-01, MW-05R, and MW-06. Vanadium was detected in the groundwater samples collected from monitoring wells MW-02 and MW-05R at concentrations of 2.8 J µg/L and 22 J µg/L, respectively. Historically, vanadium has been present above its water quality standard in the samples collected from multiple groundwater monitoring wells. 3.1.1.3 Appendix II VOCs Four VOCs (1,4-dichlorobenzene, benzene, tetrachloroethene, and vinyl chloride) were detected at concentrations above their respective 2L standards in the groundwater samples collected from one or more monitoring wells during the fall 2016 water quality monitoring event. Concentration-versus- time graphs were created for samples from those monitoring wells that had VOC concentrations over their 2L standards during the fall 2016 sampling event. The graphs are provided as Figure 4 through Figure 7. 1,4-dichlorobenzene was detected at 6.9 µg/L, slightly above the 2L standard of 6.0 µg/L in the groundwater sample collected from MW-01 during the fall 2016 sampling event. This VOC was detected in monitoring wells MW-03, MW-04, MW-05R, MW-06, and MW-07 at concentrations above the SWSL but below the 2L standard (Table 2). Historical 1,4-dichlorobenze concentration trends in these wells have been stable and slightly above or slightly below the 2L standard (Figure 4). Benzene was detected at a concentration of 1.3 µg/L, just above the 2L standard of 1.0 µg/L in the groundwater sample collected from MW-01 during the fall 2016 sampling event. Benzene was detected in monitoring wells MW-03, MW-04, MW-05R, and MW-07 at concentrations below the SWSL and 2L standard. Overall, historical benzene concentration trends in these wells have been stable and slightly over the 2L standard (Figure 5). Tetrachloroethene was only detected in the sample collected from monitoring well MW-01 at a concentration of 1.2 µg/L (Table 2), above the 2L standard of 0.7 µg/L. Historical concentration trends for tetrachloroethene in this monitoring well show consistent and stable detections with occasional 2L exceedances (Figure 6). The concentration of vinyl chloride in the sample collected from monitoring well MW-05R was below the SWSL, but above the 2L standard during this sampling event. Vinyl chloride was not detected in any of the other monitoring wells during this sampling event (Table 2). Historically, vinyl chloride has regularly exceeded its 2L standard in monitoring wells MW-04, MW-05R, and MW-07 (Figure 7). Fall 2016 Semiannual Water Quality Monitoring Report 9 February 2017 A review of historical groundwater data indicates that three VOCs (1,4-dichlorobenzene, benzene, and vinyl chloride) have been detected at relatively consistent concentrations for the past several years. Historical surface water samples from the Tuckasegee River, which likely receives discharge from the saprolite groundwater-bearing zone, have consistently shown no detections of these compounds, or any other VOCs. 3.1.1.4 SVOCs Three SVOCs (Bis[2-ethylhexyl]phthalate, diethyl phthalate, and di-n-butyl phthalate) were detected in one or more groundwater samples collected from the monitoring wells during the fall 2016 sampling event (Table 2). All three SVOCs were detected at concentrations below their respective SWSLs and groundwater standards. 3.1.1.5 PCBs One PCB, Aroclor 1016, was detected in the groundwater sample collected from MW-03 at a concentration of 5.2 µg/L (Table 2). This PCB detection exceeded the IMAC established for all PCBs (0.09 µg/L). Samples were analyzed for PCBs during the fall 2010, fall 2012, and fall 2014 sampling events. This PCB detection is the first detection of a PCB at the Site. As such, the detection at this concentration is an outlier and future monitoring will determine its significance. 3.1.1.6 Natural Attenuation Parameters Groundwater samples collected from all monitoring wells were analyzed for additional parameters as follows: alkalinity, BOD, COD, carbon dioxide, chloride, cyanide, ethane, ethene, hydrogen, methane, iron (ferrous), nitrate, sulfate, sulfide, TOC, and volatile fatty acids (Table 2). These parameters were detected in one or more groundwater samples collected from the monitoring wells. Many of these parameters do not have established groundwater standards. Of the parameters that do have established groundwater standards, none of the parameters exceeded their respective standard. 3.1.2 Surface Water The following sections summarize measured field parameters and analytical results associated with the two surface water samples collected during the fall 2016 sampling event. 3.1.2.1 Field Parameters The pH readings for the upstream and downstream surface water samples collected during the fall 2016 sampling event were recorded at 7.70 SU and 7.25 SU, respectively. The measured pH reading for both surface water samples was within the 2B standard range of 6.0 to 9.0 SU. Turbidity measured in SW-01 and SW-02 was below the 2B standard, which is established at 25 NTU for the receiving water in streams not designated as trout waters. Fall 2016 Semiannual Water Quality Monitoring Report 10 February 2017 DO was measured at a concentration of 8.05 mg/L in SW-01 and 6.65 mg/L in SW-02. The 2B standard indicates “greater than or equal to 5.0 mg/L”; thus, each sample is within the acceptable DO range. 2B standards do not exist for the remaining field parameters measured in the surface water samples. 3.1.2.2 Appendix II Metals Eleven metals were detected in surface water samples collected from downstream and upstream surface water sampling locations (Table 2). The concentration of cadmium in the upstream surface water sample (SW-01) exceeded the 2B standard established at 0.15 µg/L. This is the first event in which cadmium was detected above the SWSL and 2B standard in either surface water standard. Zinc was detected above the SWSL in SW-01, but below the 2B standard. Concentrations of the remaining metals were all below their respective SWSLs and 2B surface water standards (Table 2). 3.1.2.3 Appendix II VOCs Acetone was detected in the upstream surface water sample at a concentration below the SWSL and 2B standard (Table 2). No VOCs were detected in the downstream surface water sample. This VOC is a common laboratory contaminant. No other VOCs were detected in the upstream or downstream surface water samples (Table 2). 3.1.3 Leachate No VOCs were detected in the leachate sample collected on October 11, 2016. This is the first sampling event that no VOCs have been detected in the leachate sample. This is likely due to the drought conditions that had occurred in the summer and fall of 2016. Leachate flow into the collection tank was minimal at the time of sample collection. On September 1, 2012, leachate extraction was initiated following installation of the leachate extraction pumps in 10 landfill gas extraction wells. Between April 5, 2016 and October 11, 2016, approximately 15,347 gallons of leachate were discharged through a permanent connection to the TWSA (Table 3). From September 1, 2012 to October 11, 2016 a total of approximately 331,010 gallons of leachate have been extracted and/or discharged from the landfill (Table 3). In fall 2013 the active portion of the approved corrective action remedy was initiated. Due to the lack of VOC detections in the leachate sample collected during the fall 2016 sampling event, it must be concluded that no VOCs were removed via leachate extraction between April and October 2016. Mass removal calculations are included in Table 3. Fall 2016 Semiannual Water Quality Monitoring Report 11 February 2017 3.2 Groundwater Flow Direction Groundwater levels in the saprolite1, partially weathered rock2 (PWR), and bedrock3 are monitored at the closed MSWLF. Three bedrock monitoring wells, MW-01, MW-02, and MW-06, are located in the northern and northwestern portions of the Site (Figure 3 and Table 4). Bedrock monitoring well (MW-07) is located southwest of the landfill (Figure 3). The fall 2016 water level data collected from these four bedrock wells were used to determine generalized bedrock groundwater flow direction, which is to the southwest (Figure 3). PWR monitoring well MW-03 and saprolite monitoring wells MW-04 and MW-05R (Figure 3) are located in the central, southwest, and southern parts of the landfill, respectively. The fall 2016 water- level data collected from monitoring wells MW-03, MW-04, and MW-05R (Table 4) indicate that groundwater flow direction in the saprolite and PWR is also generally to the southwest, toward the Tuckasegee River (Figure 3). 1 Saprolite is the result of in-place weathering to produce soil-like material that retains relict features of the parent rock. 2 PWR is rock generally found above the bedrock and is softer than the bedrock but not as soft as saprolite. 3 Bedrock is solid rock that underlies loose soil and saprolite. Fall 2016 Semiannual Water Quality Monitoring Report 12 February 2017 4 Summary The second semiannual water quality monitoring event of 2016 was performed on October 11 and October 12, 2016 at the Jackson County closed MSWLF. Table 2 of this report and the Reports of Laboratory Analysis (Appendix B) provide detailed analytical results and field data summarizing the groundwater and surface water quality at the landfill. 4.1 Groundwater Quality 4.1.1 Metals Sixteen metals were detected in the groundwater samples collected from one or more of the monitoring wells. Seven of the detected metals (barium, beryllium, cadmium, chromium, cobalt, copper, and zinc) were detected at concentrations above the associated SWSLs in one or more monitoring wells (Table 2). Five metals (cadmium, chromium, cobalt, thallium, and vanadium) were detected at concentrations above their associated groundwater quality standards in one or more of the monitoring wells (Table 2). Cobalt exceeded its 2L standard in all of the groundwater samples collected. These results are consistent with historical data. 4.1.2 VOCs & SVOCs Twelve VOCs were detected in the groundwater samples collected from one or more of the monitoring wells (Table 2). Five VOCs (1,4-dichlorobenzene, benzene, chlorobenzene, tetrachloroethene, and vinyl chloride) were detected at concentrations above their respective SWSLs (Table 2). Four VOCs (1,4-dichlorobenzene, benzene, tetrachloroethene, and vinyl chloride) were detected at concentrations above their respective 2L standards (Table 2). Concentration-versus-time graphs were created for samples from those monitoring wells that had VOC concentrations over their 2L standards. The graphs are provided as Figures 4 through 7. Three SVOCs (bis[2-ethylhexyl]phthalate, diethyl phthalate, and di-n-butyl phthalate) were detected in the groundwater samples collected from one or more of the monitoring wells (Table 2). All SVOC detections were reported at estimated concentrations below their respective SWSLs and water quality standards. 4.1.3 Other Constituents One PCB, Aroclor 1016, was detected in monitoring well MW-03 at a concentration that exceeded its IMAC standard. This is the first time a PCB has been detected in any of the monitoring wells. Fall 2016 Semiannual Water Quality Monitoring Report 13 February 2017 Groundwater samples were analyzed for Appendix II herbicides. No herbicides were detected in any of the collected groundwater samples. Six of the samples collected from the monitoring wells had pH readings that were recorded outside of the 2L standard range for pH (6.5 SU to 8.5 SU). These results are consistent with historical data and are characteristic of the natural groundwater quality of the region. The turbidity was measured from the lowest reading of 3.42 NTU in monitoring well MW-04 to the highest reading being out of the range of the turbidimeter in monitoring well MW-05R. Natural attenuation parameters (alkalinity, BOD, COD, chloride, carbon dioxide, hydrogen, ferrous iron, methane, nitrate, sulfate, and TOC) were detected in groundwater samples collected from one or more of the monitoring wells at various concentrations. Natural attenuation parameters are being obtained as part of the CAP and further evaluation of these parameters will be performed in future monitoring events. 4.2 Surface Water Quality Eleven metals were detected in both surface water samples SW-01 (upstream of the landfill) and SW-02 (downstream of the landfill) during the spring 2016 water quality monitoring event. With the exception of cadmium detected at a concentration above the 2B standard in the sample collected from SW-01, all detections were below respective SWSLs and 2B standards in both samples. With the exception of acetone being detected at an estimated concentration in the sample collected from SW-01, no VOCs were detected in either surface water sample location. On the basis of these data, the groundwater migrating from the landfill toward the Tuckasegee River is not impacting surface water quality with regard to metals and VOCs. Field parameters including pH, turbidity, and dissolved oxygen measured in both surface water samples were within the 2B standards established for these parameters. 4.3 Leachate Quality The leachate sample (LT-01) was collected from the flow equalization tank and analyzed for Appendix I VOCs only. No VOCs were detected in the collected sample. Fall 2016 Semiannual Water Quality Monitoring Report 14 February 2017 5 Future Activities Anchor QEA will continue to monitor the water quality on a semiannual basis at the Jackson County Closed Municipal Solid Waste landfill. During the fall of each year, domestic well owners will be contacted and groundwater samples will be collected from domestic wells if permitted to do so by the well owner and if possible to do so based upon well pump operability. Domestic well samples will be analyzed for VOCs only. Samples will be collected from monitoring wells, surface water monitoring points, and the leachate flow equalization tank during the spring and fall of each year. In addition to the natural attenuation parameters that were added as part of the approved corrective action, the analytical suites associated with the current and future sampling events are outlined in the 2011 CAP. The upcoming sampling event parameters are as follows: Sampling Event Analytical Suite (not inclusive of natural attenuation parameters) Spring 2017 Appendix I VOCs Fall 2017 Appendix I metals Appendix II VOCs Appendix II metals Appendix II SVOCs Cyanide and sulfide Spring 2018 Appendix I VOCs Appendix I Metals The next sampling event is scheduled for April 2017.

Extraction Leachate extraction at the landfill initiated on September 1, 2012. Volume Extraction volume measurements were recorded and provided by Jackson County staff. Calculations Cumulative Flow Interpolated between LT-01 Sample Dates. Differential Flow Represents the total flow between the LT-01 Sample Dates. Mass Removed mg/L milligrams per liter. J Indicates laboratory estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. October 2016 No VOCs were detected in the leachate sample collected during the October 2016 sampling event. Anchor QEA bases mass removal calculations on the assumption that the VOCs concentration in one sampling event is representative of leachate quality until the next sampling event occurs, and that the leachate removal system has a 100% removal and treatment efficiency. Mass Removed and Treated is estimated based upon a conversion of milligrams to pounds and liters to gallons and the multiplication of the Concentration by the Differential Flow for the specified period.
