The November 2015 monitoring event is the 2nd of the requested semiannual groundwater monitoring events for year 2015. In addition to the report, the signed Environmental Monitoring Reporting Form and the electronic data deliverable (EDD) are being submitted. This groundwater and surface water sampling event was conducted on November 10, 2015. The report provides details pertaining to the sampling event including field activities, laboratory analysis, water quality findings and conclusions. Historical groundwater and surface water results are also included in the report. In summary, the results of the surface water monitoring event indicate conditions consistent with historic field and analytical data. The results of the groundwater monitoring event indicate ongoing groundwater impact at the assessment monitoring wells MW-3S and MW-3A with benzene detections. Originally assessment monitoring at wells MW-3S and MW-8 was triggered by the detection of benzene. Vinyl chloride was present at concentration above 2L Standard in well MW-6, Phase 1 detection well, for the first time. However neither benzene nor vinyl chloride were detected in wells MW-8 and MW-12S during this monitoring event. There is no indication of any risk to the public at this time. The next water quality monitoring event at the C&D Landfill is scheduled for May 2016.

This report provides background information, description of field activities, data, summary and analysis of the laboratory analytical results from the groundwater and surface water monitoring sampling event performed in November 2015. 1 INTRODUCTION C&D Landfill, Inc. operates the Construction and Demolition Debris Landfill (C&D Landfill) Phase 1 and Phase 2 located at 802 Recycling Lane, Greenville, Pitt County, North Carolina. The location of the landfill is shown on Figure 1. This C&D Landfill Phase 1 became operational in 2001 and Phase 2 became operational in 2009. The baseline monitoring was conducted in August 2009 at the Phase 2 of the C&D Landfill. Based on review of previously prepared documentation, groundwater monitoring has been performed at the permitted landfill since May 2001 for Phase 1 and since August 2009 for Phase 2. State and federal regulations applicable to landfills are enforced by the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Solid Waste Section (SWS). The C&D Landfill (Phase 1 and Phase 2) is permitted by the NCDEQ DWM under Permit No. 74-07, which requires semiannual monitoring of groundwater and surface water quality. This monitoring event is the second (2nd) semiannual monitoring event for year 2015. This report provides an evaluation of surface water and groundwater quality for the C&D Landfill Phase 1 and Phase 2. Currently, the monitoring program network at the landfill consists of twelve (12) groundwater monitoring wells within Phase 1, seven (7) groundwater monitoring wells within Phase 2, and four (4) on-site surface water sampling locations. There are two monitoring programs on-going at the site, the assessment monitoring program related to monitoring wells MW-3S, MW-3A, MW-8, and MW-12S, and detection monitoring related to the remainder of the monitoring wells. Phases 1 and 2 are separated by a man-made (channelized) drainage feature that may have once been a natural stream that originates onsite. This drainage feature predates either phase of the landfill. Within Phase 1 area there is one up gradient, background well designated as MW-1S, and eight (8) down gradient compliance wells being designated as MW-2S, MW-3S, MW-4, MW-5, MW-6, MW-7, MW-3A, and MW-8, as well as three deeper wells MW-1D, MW-2D, and MW-3D. Within Phase 2 area there is one up gradient, background well designated as MW- 9A, and six (6) down gradient compliance wells being designated as MW-10, MW-11, MW-12S, MW-13, MW-14S, and one deeper well MW-14D. Monitoring well MW-12S is located across and downgradient of the man-made drainage feature from Phase 1 well MW-8. The surface water sample locations are designated as SW-1, SW-2, SW-3, and SW-4. SW-1 is a background surface water location. SW-1 and SW-3 monitor a natural stream on the south side of Phase 1 that originates offsite to the east, with SW-1 as background. SW-2 and SW-4 monitor a channelized stream on the west side of Phase 2 that originates offsite to the north, with SW-3 as background. SW-2 is located below the confluence of the interstitial man-made drainage feature and the channelized stream on the west side of Phase 2. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 2 The locations of the monitoring wells and surface water points are showed on Figure 1. The four deeper wells mentioned above, MW-1D, MW-2D, and MW-3D (Phase 1) and MW- 14D (Phase 2) are to be sampled annually during every spring monitoring event. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 3 2 FIELD ACTIVITIES On November 10, 2015 Environment 1, Incorporated personnel collected groundwater samples from fifteen (15) groundwater monitoring wells and four (4) surface water sampling locations at the C&D Landfill for laboratory analysis of constituents listed in Appendix I of the 40 Code of Federal Regulations (CFR) Part 258 (Constituents for Detection Monitoring), Appendix II of the CFR Part 258 (Constituents for Assessment Monitoring), tetrahydrofuran, cyanide, and sulfide. The four deeper wells were not sampled during this monitoring event, because they are set up to be sampled during spring monitoring events only. The groundwater and surface water samples were collected and handled in accordance with the sampling protocols included in the Sampling and Analysis Plan dated May 2008 and Groundwater Assessment Work Plan dated June 2009, both prepared for the site by David Garrett & Associates, as well as the SWS Guidelines for Groundwater, Soil, and Surface Water Sampling. Groundwater was purged and samples were collected from the monitoring wells using bailing sampling procedures. Total well depth, condition of the casing, and the groundwater recharge rate were used to determine the purging and sample collection method employed at each monitoring well. Prior to groundwater sampling, each monitoring well was purged of a minimum of three well volumes of water. During purging, measurements were taken in the field of conductivity, pH, temperature, water levels, and turbidity. Measured field parameters and additional observations pertaining to the C&D Landfill sampling locations are provided in the laboratory analytical report, which is included in Attachment 1. All groundwater samples were placed into laboratory-supplied sample bottles by a technician wearing a new pair of nitrile gloves. Surface water samples were collected into sample containers by direct submersion in the creek and/or tributary. One round of surface water field parameters consisting of conductivity, pH, temperature, and turbidity, was measured and recorded at each sampling location prior to collecting the sample. Surface water samples were placed into laboratory-supplied sample containers by a technician wearing a new pair of nitrile gloves. All reusable sampling equipment was properly decontaminated between sampling locations. Disposable sampling equipment and material was discarded after each use. Following collection, each groundwater and surface water sample was immediately placed on ice in a sample cooler for delivery to Environment 1, a North Carolina certified laboratory located in Greenville, North Carolina. Proper chain-of-custody documentation practices were followed during collection and transportation of each sample; the documentation is included in Attachment 1 of this report. Chain-of-custody provides details of the laboratory analyses requested and performed on the samples. The laboratory analytical report is provided in the Attachment 1 also. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 4 3 GROUNDWATER LEVELS AND FLOW Groundwater levels were gauged in the monitoring wells on November 10, 2015. Depths to groundwater were measured using an electronic water level meter that was thoroughly decontaminated between wells. Depth-to-water measurements were taken after the wells were opened for a sufficient period of time to allow water levels to equilibrate with atmospheric pressure. Water level data and groundwater elevation data are summarized on Table 1. The depth to groundwater across the site measured relative to the top of the polyvinyl chloride (PVC) casing ranged from 2.43 feet (MW-11; Phase 2) to 10.94 feet (MW-3S; Phase 1), consistent with site surface topography. Based on the water level data collected during this monitoring event, a Groundwater Surface Contour Map was prepared and is presented as Figure 1. Groundwater levels during this monitoring event were slightly higher than the May 2015 levels, due to the wetter weather conditions. The pattern of the water-table contours indicates that the horizontal component of shallow groundwater flow at the site is generally to the south and southwest, which is consistent with the site surface topography and drainage features. In general, the groundwater flow direction is primarily towards the southwestern property boundary and continues to flow in the direction of areas where there are no identified groundwater users, and rather flat gradients extending through agricultural and wooded marshy land leading to the Tar River. Much of the downgradient area is beneath the 100-year flood level and is not anticipated to undergo development or groundwater use in the near future. The estimated values for hydraulic conductivity and porosity, as well as the calculated hydraulic gradient and groundwater flow velocity are presented in Table 1. The hydraulic gradient of the water table that is a horizontal gradient, calculated based on data from Figure 1, varies from approximately 0.001 to 0.014 at the site. The corresponding calculated flow velocities fluctuate between 0.002 to 0.107 feet per day. Please note that for all the monitoring wells, the estimated value for hydraulic conductivity comes from individual well aquifer tests performed by EFM, Inc. and effective porosity in the shallow aquifer are values approximated based on the grain-size data from lab testing of site soils for Phase 2 Design Hydrogeologic Report. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 5 4 WATER QUALITY FINDINGS Concentrations of detected constituents in groundwater samples were compared to analyte- specific Solid Waste Section Limits (SWSLs) established by the SWS and NCDEQ rule 15A NCAC 02L .0202 Groundwater Quality Standards (2L). Concentrations of detected constituents in surface water samples were compared to analyte-specific SWSLs and the 15A NCAC 2B.0211 surface water quality standards (2B) established for class C waters. If the reported concentration is less than the SWSL, the analytical result is qualified by the laboratory and SCS as estimated per the SWS requirement, and is flagged with a “J” qualifier. Table 2 presents summary of detected constituents only, in groundwater. Table 3 presents summary of detected constituents only, in surface water. In both tables, constituent analytical results that exceed their associated 2L or 2B standard, where applicable, are shaded. Table 4 presents summary of historically detected constituents only, in the groundwater and/ or surface water samples collected at the C&D Landfill. A hard copy of the laboratory report from Environment 1, Incorporated with a copy of the chain- of-custody form is included in Attachment 1. All laboratory analytical results and field parameter data for groundwater and surface water are included in an electronic data deliverable (EDD) spreadsheet format file specified by the SWS (available as electronic file only). 4.1 GROUNDWATER ANALYTICAL RESULTS The summary of constituents detected in the groundwater during the November 2015 semiannual water quality monitoring event is provided in the sections below. 4.1.1 VOLATILE ORGANIC COMPOUNDS (VOCS) Benzene, 2-butanone, carbon disulfide, ethylbenzene, styrene, tetrahydrofuran, toluene, and vinyl chloride were detected in one or more of the monitoring wells associated with Phase 1 during this monitoring event. Benzene was detected at concentration above the applicable SWSL and 2L standard in the two assessment wells MW-3S and MW-3A. Vinyl chloride was reported at concentration above the 2L standard in the monitoring well MW-6. Tetrahydrofuran was detected in two monitoring wells associated with Phase 2 during this monitoring event. No other VOCs were reported above their respective compliance limits in the groundwater samples collected from Phase 1 and Phase 2 monitoring wells. All detections are summarized on Table 2. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 6 4.1.2 SEMIVOLATILE ORGANIC COMPOUNDS (SVOCS) AND HERBICIDES Appendix II SVOCs (per 40 CFR 258) and herbicides were not detected in the groundwater samples collected from Phase 1 and Phase 2 assessment monitoring wells during November 2015 monitoring event. 4.1.3 METALS Sixteen (16) metals were detected in one or more of the monitoring wells associated with Phase 1 during November 2015 monitoring event. Out of the sixteen detected metals, arsenic, barium, cobalt, and selenium were found at concentrations equal to or above the applicable SWSLs in one or more of the collected groundwater samples. Arsenic, cobalt, and vanadium were found at concentrations in excess of their applicable 2L standards. Arsenic was detected in well MW-3S at a concentration above its 2L standard. Cobalt was detected above its respective 2L standard in wells MW-3S, MW-3A, MW-4, MW-5, MW-6, MW-7, and MW-8. Vanadium was also present at concentrations in excess of established 2L standard for this metal in all Phase 1 monitoring wells, including the background well MW-1S. Except for vanadium, no other detected metals were present at concentrations above compliance limits in the background well MW-1S, but ALL these metals have been detected in the background well MW-1S. Sixteen (16) metals were detected in one or more of the monitoring wells associated with Phase 2 during this monitoring event. Out of sixteen detected metals, barium, cadmium, lead, vanadium, and zinc, were found in excess or equal to the applicable SWSLs. Cobalt and vanadium were found at concentrations in excess of their applicable 2L standards. Cobalt was found at concentration above the respective 2L standard in MW-14S (detection well). Vanadium was present in the monitoring wells MW-10, MW-12S, MW-13, and MW-14S at concentrations above its 2L standard, including the background well MW-9A. The well MW- 12S is located across the shallow drainage feature from MW-8 (Phase 1 well). Cobalt detected in the groundwater sample collected from the background well MW-9A was reported at concentration below 2L standard. No other metals were reported above their respective compliance limits in the groundwater samples collected from Phase 1 and Phase 2 monitoring wells. All detections are summarized on Table 2. 4.1.4 INORGANIC PARAMETERS Neither cyanide, nor sulfide were detected in the groundwater samples collected from either Phase 1 or Phase 2 assessment wells. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 7 4.1.5 FIELD PARAMETERS The pH readings measured in Phase 1 monitoring wells ranged between 5.8 (MW-2S) Standard Units (SU) to 6.9 SU (MW-7) and for wells MW-1S, MW-2S, MW-3A, MW-4, and MW-8 were outside the 2L standard pH range of 6.5 to 8.5 SU specified in the 15A NCAC 02L .0202[c] (Table 2). The pH readings measured in Phase 2 monitoring wells ranged between 5.6 SU (MW-10) to 7.2 SU (MW-9A) and for all wells, with the exception of well MW-9A, were outside the 2L standard pH range. In overall, values of pH appear to be within a normal range at all locations. Turbidity values at the time of sampling all monitoring wells ranged from 1.30 (MW-11; Phase 2) to 393 (MW-14S; Phase 2) nephelometric turbidity units (NTUs). Specific conductivity values ranged between 138 (MW-14S; Phase 2) and 3,010 (MW-3S; Phase 1) microsiemens per centimeter (µS/cm). 4.2 SURFACE WATER ANALYTICAL RESULTS The summary of constituents detected in the surface water during the November 2015 semiannual water quality monitoring event is provided in the sections below. 4.2.1 VOCS VOCs were not reported for the collected surface water samples. Table 3 and analysis report in Attachment 1 provide further details. 4.2.2 METALS Fifteen (15) metals were detected in one or more surface water samples. None of the detected metals were present at concentrations above the applicable SWSLs and/ or 2B surface water quality standards for these constituents (Table 3). 4.2.3 FIELD PARAMETERS The pH readings measured in all surface water samples ranged between 6.4 to 6.8 SU and were within the 2B surface water quality standard pH range of 6.0 to 9.0 SU specified in the 15A NCAC 2B (Table 3). Turbidity values at the time of sampling the surface water samples ranged from 9.52 (SW-1) to 27.4 (SW-2) NTUs. Specific conductivity values ranged between 127 (SW-4) and 292 (SW-1) µS/cm. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 8 5 SUMMARY The results of the November 2015 groundwater and surface water quality monitoring event performed at the C&D Landfill indicate that the overall water quality is steady and consistent with the results reported during previous semiannual sampling events. The results are summarized in more detail in the sections below. 5.1 VOCS DETECTION SUMMARY During the November 2015 monitoring event benzene and vinyl chloride were present at concentrations in excess of their SWSL and 2L Standards. In addition, 2-butanone, carbon disulfide, ethylbenzene, styrene, tetrahydrofuran, and toluene were reported in one or more of the monitoring wells at concentrations above MDL, however below the applicable SWSLs and 2L Standards. Benzene was found in MW-3S and MW-3A, Phase 1 assessment wells, at concentrations in excess of the 2L Standard established for benzene. The presence of benzene has been consistent with its historical detections reported for well MW-3S. The detected concentration appeared slightly higher comparing to the one reported during May 2015 monitoring event. Historically benzene has been reported in the groundwater samples collected from well MW-3A, however for the first time during this monitoring event the reported concentration was in excess of the 2L Standard. During November 2015 monitoring event vinyl chloride was found in one monitoring well MW- 6 at concentration in excess of the 2L Standard. Vinyl chloride has not been reported in this well before. During November 2015 monitoring event 2-butanone was found in the groundwater sample collected from monitoring well MW-4 (Phase 1) at concentration below its SWSL and 2L Standard. Previously 2-butanone was reported for the first time as present in the groundwater sample collected from monitoring well MW-5 (Phase 1) at concentration below its SWSL and 2L Standard in May 2015. Before May 2015 event 2-butanone had not been reported as present in the groundwater at the site. During November 2015 monitoring event carbon disulfide was found in the groundwater sample collected from monitoring well MW-5 (Phase 1) at concentration below its SWSL and 2L Standard. Previously in May 2015 carbon disulfide was found in the groundwater samples collected from several monitoring wells at concentrations below its SWSL and 2L Standard also. Before May 2015 event carbon disulfide had not been reported as present in the groundwater at the site. During November 2015 monitoring event ethylbenzene and styrene were found in the groundwater sample collected from monitoring well MW-3S (Phase 1 assessment well) at concentrations below the applicable SWSLs and 2L Standards. These are the first detections of ethylbenzene and styrene reported in the groundwater sample collected from this well. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 9 Tetrahydrofuran was detected in the groundwater samples collected from seven (7) monitoring wells MW-3S, MW-3A, MW-5, MW-7, MW-8, MW-11, and MW-12S during November 2015 monitoring event. Tetrahydrofuran has been consistently present in the groundwater at the site, since sampling for this parameter began in 2011. There is no regulatory standard established for tetrahydrofuran, therefore the implications of these results have yet to be determined. Toluene was reported in MW-3S (Phase 1 assessment well) groundwater sample during this monitoring event at concentration below its SWSL and 2L Standard. Since January 2010 monitoring event this is the second toluene detection in the groundwater sample collected from MW-3S well. Neither constituent shows a trend and has not been tied to the landfill operations. VOCs were not detected in the surface water at the site. Historically, presence of VOCs in the surface water samples is inconsistent and no trends could be discerned from the collected data. The historical analytical data for previously detected VOCs in the groundwater and surface water are presented in Table 4. 5.2 HERBICIDES DETECTION SUMMARY Herbicides were not detected during November 2015 monitoring event. Data from May 2010, 2012, 2013, and 2014 monitoring events indicate trace values of common herbicides that might have been used during the former agricultural activities at the site. The impact might originate from a man-made drainage ditch between Phase 1 and Phase 2, but the full history of this portion of the site is unknown. 5.3 METALS DETECTION SUMMARY Arsenic, cobalt, and vanadium were found in the groundwater at concentrations equal to or in excess of the respective 2L Standards during November 2015 monitoring event in one or more Phase 1 and Phase 2 monitoring wells. These detections however, do not appear to indicate any consistent pattern. Arsenic was detected in MW-3S above its 2L Standard during November 2015 monitoring event. Arsenic has been consistently present in MW-3S groundwater, however this is the first arsenic detection at concentration in excess of the respective 2L Standard. Arsenic was reported in the background well MW-1S (Phase 1) during this monitoring event. Historically arsenic has been consistently present in the groundwater across the site, including the groundwater from background wells, however majority of the detected concentrations stay below the 2L Standard. Cobalt was found in excess of its 2L Standard in wells MW-3S and MW-3A (assessment wells), MW-4, MW-5, MW-6, MW-7, MW-8 (assessment well), and MW-14S. Historically, cobalt has been present in the groundwater samples collected from all abovementioned wells at concentrations above 2L Standard, however no data trends can be discerned. Cobalt has been reported in the groundwater samples collected from background wells MW-1 and MW-9A since May 2010 monitoring event, however the concentrations were found below its 2L Standard. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 10 Vanadium was detected in all sampled monitoring wells above 2L Standard, including both, Phase 1 background well MW-1S and the Phase 2 background well MW-9A. Vanadium has been consistently present in the groundwater across the site. Detected concentrations during the November 2015 monitoring event appear higher for majority of the wells comparing to the May 2015 reported detections. It has to be noted that the highest turbidity value was measured at 393 NTUs (well MW-14S) at monitoring wells. Also, turbidity measured at wells MW-9A and MW-14S was higher comparing to the measurements obtained during previous monitoring events. Detected metals in surface water samples were found below their respective 2B standards established for analyzed constituents. No trends can be discerned from the surface water data. Metal concentrations in groundwater are often dependent on the turbidity or suspended particulates (from the aquifer formation) retrieved with the groundwater sample and also metals naturally occurring in the in-situ soil. The turbidity is a function of the sampling method, well construction, well development, depth to groundwater, and grain size/consolidation of the water- bearing zone. Since unfiltered samples are acidified in the field at the time of sample collection, metals contained within the particulates are dissolved into the water sample. Thus, the presence of turbidity in groundwater samples often results in elevated (false positive) analytical concentrations for metals. Therefore, the presence of elevated metal concentrations does not necessarily indicate a groundwater impact. Additionally, certain metals are considered naturally occurring within the in-situ soils and not caused by a release from a landfill. The historical analytical data for metals detected in the groundwater and surface water are presented in Table 4. 5.4 INORGANIC AND FIELD PARAMETERS During November 2015 monitoring event neither cyanide nor sulfide was reported present in any of the groundwater samples collected from the assessment monitoring wells. The results of the field-measured groundwater quality parameters indicate that the values measured in the collected samples were consistent with historic reported values. The pH readings measured in some of the monitoring wells were outside the 2L standard pH range specified in the 15A NCAC 02L .0202[c] and indicate slightly acidic groundwater. In general, values of pH appear within a normal range at all locations. The turbidity values appeared higher comparing to the ones reported during May 2015 monitoring event in majority of the collected samples, especially in the ones collected from wells MW-9A and MW-14S. The results of the field-measured surface water quality parameters indicate that the values measured in the collected samples were generally consistent with the historic data. The highest turbidity measurement was taken at the SW-2 sampling location. C&D Landfill, Water Quality Monitoring Report November 2015 Semiannual Sampling Event 11 5.5 CONCLUSIONS The results of the groundwater monitoring event indicate ongoing groundwater impact at the assessment monitoring wells MW-3S and MW-3A, with benzene detections. Originally assessment monitoring at wells MW-3S and MW-8 was triggered by the detection of benzene. Benzene continues to be present in well MW-3S above the SWSL and 2L Standard, as well as in well MW-3A, for the first time during the November 2015 monitoring event at concentration reported above both SWSL and 2L Standard. Vinyl chloride was reported in the groundwater sample collected from well MW-6 only, for the first time at concentration reported above 2L Standard in this well. Neither benzene nor vinyl chloride were detected in the assessment wells MW-8 and MW-12S during the November 2015 monitoring event. However, monitoring well MW-12S will continue to be included in the assessment program, in order to observe detections at this well, and if they are associated with the ones found at nearby assessment well MW-8. The groundwater quality impact does not appear severe and may not be attributable to landfill activities. There is no indication of any risk to the public at this time. The results of the surface water monitoring event indicate conditions consistent with historic field and analytical data, and do not demonstrate an impact on surface water quality due to landfill activities. The next water quality monitoring event at the C&D Landfill is scheduled for May 2016.

Depth To Water was measured on November 10, 2015 for monitoring wells. 2. TOC = top of casing. TOC elevation in feet MSL (mean sea level). 3. Well Depth and Screened Interval in feet below GS. 4. Depth To Water in feet from TOC. 5. Phase I monitoring wells (MW-3A through MW-8) were surveyed (July 2001 and November 2002) by Burgess Land Surveying from Greenville, South Carolina. 6. Phase II monitoring wells (MW-9A through MW-14S) construction data obtained from records furnished by David Garrett, PG, PE. 7. K - hydraulic conductivity. Values obtained from slug testing performed by EFM, Inc. 8. ft = feet. 9. n - effective porosity. Values approximated based on the grain-size data from lab testing of site soils for Phase II Design Hydrogeologic Report. 10. I - hydraulic gradient. Values obtained by dividing water level elevation difference by horizontal distance between closest two contour lines to each well location. 11. v - flow rate; GW flow rate calculated based on the modified Darcy equation: v = (K*I)/n. 12. During May 2014 monitoring event MW-5 well depth was measured at 21.06 feet. Well depth was not measured and groundwater sample was not collected during November 2014 monitoring event due to well damage. Well depth changed for May 2015 monitoring event since MW-5 was reinstalled.
