Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 1 1.0 INTRODUCTION 1.1 Site Information The Rockingham County Solid Waste Management Facility (the Facility) is owned and operated by Rockingham County and is operating under North Carolina Solid Waste Permit Nos. 79-01 and 79-04. The Facility is located off Shuff Road, west of the town of Wentworth in central Rockingham County, North Carolina. The property boundary is indicated on an excerpt from the 7.5 minute USGS topographic map for Bethany and Southwest Eden, North Carolina (Figure 1). The property is surrounded by rural wooded areas and farmland. The Rockingham County Solid Waste Management Facility consists of three waste disposal areas. Areas I, II, III, and IV (I-IV) and Area V are closed unlined municipal solid waste (MSW) landfill areas under Permit No. 79-01. The active Subtitle D MSW landfill is covered under Permit No. 79-04. 1.2 Site Geology The Facility is located in the Piedmont physiographic province. Geologically, the site is located in the Milton Belt, which contains schist and gneiss of amphibolite facies, with minor areas of granitic intrusive rock. Regional geology is shown on the Geologic Map of Region G, North Carolina (Carpenter, 1982). Carpenter mapped bedrock in the vicinity of the site as the mgs unit, which contains biotite gneiss and schist, locally interlayered with hornblende gneiss and schist and felsic gneiss. Map patterns and outcrop information for the Milton Belt indicate that the metamorphic rock is broadly folded, with foliation of moderate to gentle dips. Strikes for outcrops are variable, owing to the generally flat-lying nature of the geologic structure; the regional strike is to the east-northeast (Carpenter, 1982). Triassic diabase dikes shown in the region, mapped on the basis of aeromagnetic surveys and occasional outcrop, have consistent strikes of approximately 10 to 20 degrees west of north. Quaternary alluvium is mapped in the larger drainages in the site vicinity, including Jacob’s Creek and its tributaries. 1.3 Regulatory Status The Closed Landfill Areas I-IV were closed prior to implementation of RCRA Subtitle D requirements. The landfill is currently monitoring groundwater in accordance with criteria set forth in Rule .0500 of the North Carolina Solid Waste Management Regulations (NCSWMR) for municipal solid waste landfills (MSWLF) closed prior to October 9, 1993. The Closed Landfill Area V groundwater monitoring is completed in accordance with NCSWMR § 1633 (Detection Monitoring Program) and NCSWMR § 1634 (Assessment Monitoring Program). ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 2 The Subtitle D Landfill groundwater and surface water monitoring is completed in accordance with NCSWMR § 1633 (groundwater) and § 0602 (surface water). Statistical analysis of the laboratory data has been prepared in accordance with the required compliance demonstration of NCSWMR .1632(g) and (h). 2.0 FACILITY MONITORING PROGRAMS Groundwater monitoring programs for each of the landfills, surface water, and leachate storage system are discussed in the following sections and locations are shown on Drawing 1. 2.1 Closed Landfill Areas I-IV Monitoring Program The Closed Landfill Areas I-IV was closed prior to implementation of RCRA Subtitle D requirements. Groundwater monitoring at the facility is completed as required by the NCSWMR. Groundwater samples are collected semiannually and analyzed for all constituents listed in NCSWMR Appendix I. The groundwater monitoring network for the Closed Landfill Areas I-IV originally consisted of one upgradient well (MW-4A) and four downgradient wells (MW-3A, MW-6, MW-7, and MW-8). In a letter from the Solid Waste Section (SWS) dated July 28, 2000, which was received prior to the July 2000 event, MW-3A and MW-8 were approved for removal from the sampling requirements for detection monitoring, but continue to be monitored for water levels only. In the same letter, two additional pairs of wells, MW-12S/MW-12D and MW-13S/MW- 13D were added to the compliance monitoring system and sampled for the first time during the June 2001 event. Well pair MW-13S/MW-13D is sampled semiannually, while the pair MW-12S/MW-12D is sampled bi-annually (beginning in June 2001), as directed in the same correspondence.

Groundwater samples are collected semiannually and analyzed ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 3 for all constituents listed in NCSWMR Appendix I list, except for MW-9 and MW-11, which are sampled for the NC Appendix I plus additional detected Appendix II constituents during both semiannual events. MW-5 entered assessment monitoring and was sampled for the NC Appendix II list of constituents starting with the second semiannual groundwater monitoring event of 2010 through the first semiannual groundwater monitoring event of 2012. Modifications to the monitoring program were made per correspondence received by the County from the SWS dated October 4, 2010. Following the first semiannual 2012 groundwater monitoring event, MW-5 will remain in assessment monitoring but will monitor for a reduced list of parameters consisting of only NC Appendix I metals and NC Appendix I volatiles. The groundwater monitoring network at the Closed Landfill Area V consists of one upgradient/background well (MW-1A) and three downgradient wells (MW-5, MW-9, and MW-11). Monitoring well MW-2A, which was sampled during previous events, was removed from the list of sampling locations based on the SWS letter dated July 28, 2000. MW-2A continues to be monitored for water levels only. Rockingham County received a letter from the SWS dated January 8, 2004, instructing the County to proceed with an assessment of corrective measures at the Closed Area V Landfill. The County submitted an Update on Groundwater Assessment Activities to the SWS on May 6, 2005. In a letter dated October 4, 2010, the SWS granted conditional approval for the removal of NES-1 from the sampling requirements of semiannual monitoring, but NES-1 will continue to be monitored for water levels only.

Groundwater samples are collected semiannually and analyzed for all constituents listed in NCSWMR Appendix I. The groundwater monitoring network at the Subtitle D area consists of two upgradient/background wells and twenty-two downgradient wells summarized in the following table (MW-18 is monitored for static water level only). ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 4 Monitoring Well Date Installed Classification Monitoring Program Total Depth from TOC (ft) Lithology of Screened Interval MW-1/1S 1/26/95 Background Detection 54.26 Saprolite MW-1D 2/01/95 Background Detection 76.80 Bedrock MW-2 1/27/95 Compliance Detection 52.92 Saprolite MW-3 1/31/95 Compliance Detection 53.85 Saprolite MW-4 3/16/95 Compliance Detection 44.25 Saprolite/Bedrock MW-5D 1/31/95 Compliance Detection 50.15 Bedrock MW-6 1/31/95 Compliance Detection 44.76 Saprolite MW-7D 3/15/95 Compliance Detection 65.15 Bedrock MW-8 3/16/95 Compliance Detection 62.77 Bedrock MW-9 3/16/95 Compliance Detection 66.02 Bedrock MW-10D 3/13/95 Compliance Detection 55.00 Bedrock MW-11 3/14/95 Compliance Detection 41.05 Bedrock MW-12 2/03/95 Compliance Detection 42.75 Bedrock MW-13D 2/02/95 Compliance Detection 67.75 Bedrock MW-14 3/17/95 Compliance Detection 31.10 Bedrock MW-15 7/07/99 Compliance Detection 29.00 Saprolite MW-16S 7/20/99 Compliance Detection 34.50 Saprolite/Bedrock MW-16D 7/21/99 Compliance Detection 63.00 Bedrock MW-17S 7/20/99 Compliance Detection 30.50 Saprolite MW-17D 7/21/99 Compliance Detection 60.00 Bedrock MW-18 10/24/03 Observation Water Level 36.92 Saprolite MW-19 11/21/03 Compliance Detection 23.17 Saprolite/Bedrock MW-19R 9/20/12 Compliance Detection 33.00 Saprolite/Bedrock MW-20S 10/06/05 Compliance Detection 42.60 Partially Weathered Rock MW-20D 10/06/05 Compliance Detection 78.00 Bedrock 2.4 Surface Water Monitoring Program Surface water monitoring at the Facility is completed in accordance with the NCSWMR and the approved Water Quality Monitoring Plan. Surface water samples are collected semiannually and analyzed for the constituents listed in NCSWMR Appendix I. The surface water monitoring network includes one upstream surface water sampling point (SMP-3), three downstream surface water monitoring points (SMP-1, SMP-2, and SMP-4), and one surface water monitoring point (SMP-5) located at the end of the underdrain from Phase 3 before entering the sediment trap.

The following constituents are required for laboratory leachate analysis:  North Carolina Appendix I Metals  North Carolina Appendix I 8260 Volatiles  Total Suspended Solids (TSS)  Biochemical Oxygen Demand (BOD)  Nitrogen, Nitrate  Total Phosphorus  Chemical Oxygen Demand (COD)  Sulfate 3.0 FIRST SEMIANNUAL SAMPLING EVENT OF 2016 3.1 Field Work On March 29-31, 2016, personnel from Joyce Engineering (JOYCE) visited the Facility to obtain water levels to the nearest 0.01 foot, purge, and sample monitoring wells at the Closed Areas I-IV, Closed Area V, and Subtitle D Landfills. Four surface water monitoring points (SMP-5 was dry) and one leachate monitoring point was also sampled during the March 2016 event. In addition, at monitoring wells that are not part of the compliance network, depth-to-water measurements were obtained to the nearest 0.01 foot using an electronic water level indicator. Monitoring wells were purged and sampled using disposable bailers or a 12 volt plastic pump during the March 2016 event. Measurements of temperature, pH, specific conductivity, and turbidity were recorded 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). ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 6 During the sampling event, groundwater samples from each monitoring well were collected directly from the bailers and transferred to 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 on ice. Surface water samples were collected directly from stream flow, by lowering the prepared sample containers into the stream. 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 was also measured for temperature, pH, specific conductivity, and turbidity. After collection, the samples were placed in a laboratory provided cooler and chilled on ice. Leachate samples were collected from a leachate lagoon. Prepared sampling containers were filled, placed in a cooler, and chilled on ice. At the time of sampling, leachate was measured for temperature, pH, specific conductivity, and turbidity. On May 9, 2016, personnel from Joyce Engineering (JOYCE) was on-site to collect verification samples from the Subtitle D Area (Permit 74-09) monitoring wells MW-19, MW-19R, and MW-20S. Sampling was performed following the same proceedures described above. 3.2 Laboratory Analysis and JOYCE Quality Control The March 2016, groundwater, surface water, and leachate 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 reports. The samples were received by the laboratory on April 1, 2016, in good condition, properly preserved, and within analysis hold times. In addition to samples collected for compliance monitoring at the facility, a Field Blank was collected by JOYCE personnel as part of the March 2016 sampling. Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling containers during shipment. The Field Blank was analyzed for North Carolina Appendix I constituents plus mercury, tin and dichlorodifluoromethane while the Trip Blank was analyzed for NCSWMR Appendix I volatile organics plus dichlorodifluoromethane only. Upon receipt of complete initial laboratory data packages on April 11, 2016, 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 North Carolina SWSLs, groundwater and surface water standards; and  Detections that are above historical levels. ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 7 Due to suspect VOC detections in MW-19, MW-19R, and MW-20S that were inconsistent with recent historical trends, a verification sampling event was performed on May 9, 2016. The complete data package was received from Pace Analytical Services on May 20, 2016. 4.0 HYDROGEOLOGY Depth to groundwater was measured in each monitoring well at the site prior to purging. The groundwater elevation at each well was calculated relative to the surveyed measuring point (top of casing) for each monitoring well. Tables 1A, 1B, and 1C summarize the groundwater elevations. Groundwater elevation contours were interpreted from the March 2016 water level measurements to create the potentiometric surface map. Groundwater flow paths at the site converge on the creeks that bisect the site and border it to the west-southwest. Groundwater flow beneath the Closed Area I-IV and Area V Landfills is predominantly to the south. Flow beneath the Subtitle D Area Landfill is radial from the southeast to the north, northwest, and west. The potentiometric surface contours for groundwater are shown on Drawing 1. Horizontal groundwater gradients were estimated based on the March 2016 groundwater levels. Gradients were estimated from groundwater flow arrow segments that intersect potentiometric surface contours. These gradients are summarized in Table 2. The horizontal gradients were calculated as approximately 0.06 to 0.07 ft/ft for Closed Areas I-IV, approximately 0.06 ft/ft for Closed Area V, and range from 0.07 to 0.11 ft/ft for the Subtitle D area. These gradients are consistent with previous gradient estimates (CDM, 1996; JOYCE, 1998). Average hydraulic conductivities (K) from each slug-tested well were used to estimate average linear groundwater flow velocities. Linear groundwater flow velocities for wells screened in saprolite were computed using the following modified Darcy equation: V = Ki/n, where V = average linear velocity (feet/day), K = hydraulic conductivity (ft/day), i = horizontal hydraulic gradient, and n = effective porosity. The linear groundwater flow velocity estimates are approximately 1.47 to 1.84 ft/day in Closed Areas I-IV, 1.99 ft/day for the Closed Area V, and from 1.66 to 21.06 ft/day for the Subtitle D area as shown in Table 2. These ranges are consistent with previous estimates (CDM, 1996; JOYCE, 1998). The linear velocity equation and resulting rates make the simplified assumptions of a homogeneous and isotropic aquifer. This equation can over-estimate velocities when applied to heterogeneous and/or anisotropic conditions such as are believed to exist at this site. Site boring logs record that regolith sampled at the site often exhibited the remnant foliation and other parent rock textures. These characteristics can impart locally anisotropic groundwater flow ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 8 directions. The regolith and bedrock are hydraulically connected, but effective porosity typically declines markedly downward into underlying fractured bedrock (Harned, 1989). 5.0 DATA ANALYSIS AND STATISTICAL RESULTS Results from the March 2016 sampling event were received on April 11, 2016, and the results from the May 2016 verification sampling event were received on May 20, 2016, from Pace Analytical Services, Inc. Analytical results from the March and May 2016 sampling events are found in Appendix 1. Statistical comparisons of baseline monitoring data to compliance groundwater data are part of the required compliance demonstration [NCSWMR .1632(g), (h), and (i)] for the detection monitoring wells at the Subtitle D Landfill. Background data and statistical methods used to evaluate the data from and the Area V Landfill and Subtitle D Landfill are discussed as follows. 5.1 Analytical Results and Comparisons to Standards 5.1.1 Closed Landfill Areas I-IV The following constituents were detected at quantified concentrations above the solid waste section report limits (SWSL’s) during the March 2016 sampling event for the Closed Landfill Areas I-IV in one or more compliance monitoring wells.

Resample results included below constituent to be verified The inorganic and organic analytical results from the March 2016 sampling event and May 2016 verification sample event at the Subtitle D Landfill are summarized in Table 7 and field parameters are summarized in Table 8 of this report. The results, as reported by the laboratory, the laboratory quality assurance/quality control information, and the chains of custody are included in Appendix 1. Cobalt detections above the GWPS have been addressed in the Alternate Source Demonstration – Cobalt approved by the DENR in a letter dated May 9, 2011. Beryllium was detected above its GWPS in MW-7D, and arsenic in MW-17D, however, the detections were each below the site specific calculated background concentrations (see section 5.3). Since beryllium and arsenic were below the site specific calculated background values, there were no exceedances of the GPS as defined by rule .1634.g. No other inorganic constituents were detected above their NC 2L or GWPS. Organic constituent results included quantified detections above NC 2L standards for benzene in MW-19, benzene and vinyl chloride in MW-19R, and benzene for MW-20S. The benzene, along with trichlorofluoromethane, represents the first quantified organic detections reported for ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 11 MW-20S. A resample verification event for the organic constituents in exceedance from the March 2016 results also included the full Appendix I list of VOCs for MW-20S in order to confirm the first time detections of any organic constituents in MW-20S. The results of the May 9, 2016 resample event confirmed benzene above the NC 2L in MW-19; however it did not confirm the benzene exceedance in MW-19R, nor the detection of vinyl chloride. The results for MW-20S indicated the presence of constituents benzene; 1,2-dichloroethane; cis-1,2- dichloroethene; and vinyl chloride at estimated concentrations; however, it did not confirm benzene in exceedance of the NC 2L. 5.1.4 Surface Water There were no quantified detections of NC Appendix I constituents in surface water samples during the March 2016 sampling event. The inorganic and organic analytical results from the March 2016 monitoring event for surface water are summarized in Table 9 and field parameters are summarized in Table 10 of this report. The results, as reported by the laboratory, the laboratory quality assurance/quality control information, and the chains of custody are included in Appendix 1. Based on this data, it appears the surface water in the area is not being negatively impacted by the Closed Landfill Area 1-IV, Closed Landfill Area V, or Subtitle D Landfill. 5.1.5 Leachate The following constituents were detected at quantified concentrations in leachate during the March 2016 sampling event.

The results, as reported by the laboratory, the laboratory quality assurance/quality control information, and the chains of custody record are included in Appendix 1. 5.2 Statistical Methods The data were evaluated through the use of the Shapiro-Wilk Test, Parametric Prediction Limits, Parametric Tolerance Intervals, Aitchison’s Adjustment, Non-parametric Prediction Limits, and Poisson Prediction Limits, as appropriate. Background data, tests for normality, outliers, ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 12 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. Statistical background values were calculated using data from historical semiannual sampling events at the Subtitle D landfill. 5.3 Statistical Results There were no inorganic constituents in the Area V landfill that were detected above their NC 2L or GWPS during the first semiannual 2016 monitoring event. At the Subtitle D landfill, beryllium in MW-7D was detected above its GWPS, and arsenic in MW-17D was detected above the NC 2L standard. The arsenic and beryllium detections were statistically evaluated in accordance with the procedures outlined in 15A NCAC 13B.1632 (g) and (h) to determine if the reported concentration exceeded the facility background concentrations. Constituent Data Distribution Statistical Method used to Establish Background Background Concentration NC2L/ (GWPS) Arsenic (Sub D) 100% ND Upper Poisson Prediction Limit 98 µg/L 10 µg/L Beryllium (Sub D) 81 % ND Non Parametric Prediction Limit 71 µg/L (4 µg/L) The statistical worksheets for arsenic and beryllium are presented in Appendix 2. Based on the statistical evaluation, the detections of arsenic and beryllium were not identified as statistically significant and are representative of historical background concentrations. 6.0 CONCLUSIONS Based on the analytical results from the March 2016 sampling and May 2016 verification events, Rockingham County will continue to monitor the uppermost aquifer beneath the Area I-IV landfills in accordance with the requirements as outlined in Title 15A NCAC 13B.0500 while the Area V and Subtitle D landfills will continued to be monitored as outlined in Title 15A NCAC 13B .1633 & .1634. The next semiannual sampling event is tentatively scheduled for August 2016. The following paragraphs discuss the historical trends and conclusions regarding previous detections for MW-19 and MW-19R. Three VOCs, benzene, 1,2-dichloroethane (DCA) and vinyl chloride were historically detected in MW-19. Benzene and DCA were detected in MW- 19 for the first time in October 2011, after five years of sampling from that well. Vinyl chloride was first detected in April, 2012. Since first being detected, the concentration of benzene in MW-19 peaked in the December 2011 sampling event, and in four subsequent sampling events ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 13 has steadily declined. In the April 2013 event, the concentration of benzene in MW-19 dropped to below the 2L standard. The concentration of DCA peaked in April 2012 and has declined in the last two events, to a level below the standard. Vinyl chloride first appeared in April 2012 and has declined in the two subsequent sampling events to be below its standard, so in the October 2012 sampling event, only benzene remained above the standard at a concentration of 1.2 µg/L, as compared to the standard of 1 µg/L. Prior to the October 2012 sampling event, MW- 19 replacement well MW-19R was installed. JOYCE believed, based on field observations that the integrity of the seal in MW-19 may have been compromised as a result of significant erosion in the area of the well. At the request of NCDENR, MW-19 was left in place following the installation of MW-19R, and both wells were sampled. The benzene concentration in MW-19R was a non-detect in the April 2013 event. On February 8, 2013, JOYCE submitted an Addendum to the April 2012 Alternate Source Demonstration (ASD). As suggested in the April 19, 2012 ASD, the additional data submitted in the Addendum supported the conclusion that the likely source of the VOCs was an isolated random release rather than an ongoing release from the landfill. This was suggested by the sudden appearance and the rapid decline in concentration since a peak at the time of first detection or shortly thereafter. The decline suggested that there was not an ongoing source and that natural diffusion, dispersion and biodegradation is successfully degrading the VOCs. All three detected constituents were below the applicable standard. On March 25, 2013, in a response to the ASD Addendum, NC DENR concurred that the appropriate action at this point was to continue to monitor the decline for two additional sampling events (April 2013 and October 2013) before requiring any additional response actions. For the October 2013 event, benzene exceeded the 2L standard in both MW-19 and MW-19R, up from both being either below detection limits or below the 2L standard in the April 2013 event. Because this one data set represented a reversal of the prior downward trend for benzene in both wells, JOYCE requested that the review period be extended an additional two monitoring events (April 2014 and October 2014) before any decisions are made regarding the need to enter into assessment monitoring. For the September 2014 event, benzene exceeded the 2L standard in both MW-19 and MW-19R, up from both being below the SWSL and NC 2L standard in the April 2014 event. This one data set represented a reversal of the prior downward trend for benzene in both wells. In a phone conversation on November 13, 2014, Joyce discussed these results with Ervin Lane of NC DENR, and it was agreed that since the concentrations of benzene have fluctuated from just above to below the NC 2L standard over the last few events, we could wait to see the results of the next event (Spring 2015) before determining whether to initiate Assessment Monitoring. Since benzene concentrations in MW-19 & MW-19R were not exceedances in the March 2015 sampling and were non-detect in the September 2015 sampling event, therefore Assessment Monitoring was not required. During the March 2016 water quality monitoring event, the initial laboratory data results included exceedances of the NC 2L standards for benzene in MW-19; as well as benzene and ____________________________________________________________________________________________ First Semiannual Water Quality Monitoring Report of 2016 Joyce Engineering Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 July 2016 14 vinyl chloride in MW-19R. A verification sampling event was performed on May 9, 2016. The results of which confirmed the benzene detection above the NC 2L standard in MW-19; however, the verification sampling refuted the benzene and vinyl chloride exceedances in MW-19R. MW-19R is downgradient and closer to the Facility’s property line than MW-19 (see Drawing 1). The extent of the plume appears to be limited to within the facility property. 7.0 REFERENCES Camp Dresser & McKee (CDM). January 1996.

ND = Not detected above laboratory reporting limit (October 1996 - June 2006). Not detected above the laboratory detection limit (December 2006 - Present). '--- = Not Sampled and/or Not Reported. NI = Not Installed. An NI designation indicates the well was not installed, exterior well construction not complete, not developed, or prior to background sampling. NC 2L = North Carolina 2L Groundwater Standard. GWPS = Groundwater Protection Standard. Bold values are above the NC 2L Groundwater Standard or Groundwater Protection Standard (GWPS). When the NC 2L Standard has not been established, the GWPS will substitute. { } = When Method Blank concentrations are higher than Trip or Field (Equipment) Blank concentrations and there are multiple Method Blanks for a sample set, use the brackets to assign Method Blank data to specific data sets.
