Page 1 of 2 Compounds Detected At or Above Groundwater or Surface Water Standards during the January 2023 Sampling Event (1/18-19/2023) - Southern Unit of the Pitt County Municipal Solid Waste Landfill (Permit #74-01) Preliminary analysis of cause and significance of concentrations detected at or above groundwater or surface water standards: 1,4-Dioxane, chromium, barium, and benzene were detected at concentrations exceeding the 15A NCAC 02L groundwater standards in six monitoring wells for the Southern Unit. However, none of these constituents were detected at concentrations above state standards in groundwater samples collected from just below the southern property ditch (which generally acts as a local groundwater discharge feature) or in the downgradient surface -water sample. These results suggest that 1,4-dioxane, benzene, and concentrations in excess of naturally occurring barium are not migrating off -site at this time. Further, 1,4-dioxane was not detected in the "deep" down -gradient well P20D, which previously had low level concentrations detected during the July 2022 sampling. The absence of target compounds indicates that benzene and non-native baium have not migrated out of the Surficial/Yorktown Aquifer at the site. Barium, benzene, and 1,4-dioxane were detected above the 15A NCAC 02L standards in wells P16R, P19, and P20R. Completed cap and stormwater upgrades are expected to reduce the concentrations of all contaminants in groundwater downgradient of the Southern Unit over time. However, more time is needed before significant reductions are achieved. The detection of 1,4-dioxane in well P29, which is located between the Northern and Southern Landfill Units, indicates that the Northern Unit is likely also a source for target contaminants. Cap repairs were designed to limit the infiltration of rainwater into the Southern mound and reduce leachate volume and concentrations.

Laboratory Report and Chain -of -Custody Forms for Water Samples 1.0 INTRODUCTION The inactive Pitt County Solid Waste Municipal Landfill (Facility Permit #74-01, Figure 1) is comprised of a Northern Unit that closed in 1990 and a Southern Unit that reached capacity and closed in 1995. Based on its closure date, the Southern Unit is subject to the September 1993 rules for municipal solid waste landfills (15A NCAC 13B .1600). The Northern Unit, on the other hand, is subject to the conditions of the solid waste permit and 15A NCAC 13B .0500. Pitt County (the County) is currently working to address 1,4-dioxane and benzene groundwater contamination at the Southern Unit of the inactive Pitt County Solid Waste Municipal Landfill (Facility Permit #74-01, Figure 1). In 2017, the County confirmed slight exceedances of the NC Groundwater Quality Standard (NCAC 02L) for benzene in two groundwater samples collected from the landfill's monitoring well network. Exceedances of the NCAC 02L groundwater standard for 1,4-dioxane were confirmed in January 2019. Testing for 1,4-dioxane began in response to a May 2018 directive from the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Solid Waste Section (SWS) that required all North Carolina landfills to begin testing for the constituent as part of their routine groundwater monitoring (Appendix A). Groundwater contamination at the facility is believed to be related to the degradation of the low -permeability, clay caps that cover each unit. Over time, erosion of the caps, as well as cracking due to heating/cooling, desiccation, and/or subsidence due to decomposition of fill material, increases the permeability of these barriers and allows infiltration of water that can leach contaminants downward into the underlying groundwater. Following approval from the SWS, the County has collected groundwater samples from just beneath the southern ditch to monitor the extent of 1,4-dioxane and benzene contamination at the facility. This ditch serves as a groundwater discharge location for the Southern Unit. To date, 1,4-dioxane and benzene have not been detected in exceedance of the NCAC 02L standards in these samples, which suggests that 1,4-dioxane and benzene contamination above the NCAC 02L groundwater standard does not extend off the facility property. On November 4, 2020, the County began construction on an extensive cap and a stormwater system repair and upgrade project at the Southern Unit as part of an approved pilot study for corrective action (Appendix A). These improvements are designed to greatly reduce the infiltration of water through the cap in order to protect the groundwater from further contamination via leaching from landfill waste. The County completed construction on this $1.065 million project in June of 2021. The County continues to monitor groundwater and surface water at the Southern Unit on a semi-annual schedule. An extension of the pilot study through July 2023 was approved by the NCDEQ Division of Waste Management, Solid Waste Section, in a letter dated November 15, 2022. The remainder of this report presents the results January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 2 of 14 of the January 2023 semi-annual monitoring event and provides an update of the ongoing pilot study at the Southern Unit of the Pitt County Landfill. 1.1 Site Background The Pitt County Landfill occupies approximately 156 acres along Allen Road west of the city of Greenville, NC (Figure 1). The landfill is comprised of a Northern Unit that closed in 1990 and a Southern Unit that reached capacity in 1995. An east -west trending railroad (Norfolk Southern Railroad) separates the Northern and Southern Units. The Pitt County landfill is unlined, and leachate is not collected. The Northern Unit received waste from 1974 until 1990, and the Southern Unit received waste from 1991 until 1995. Due to the closure dates, only the Southern Unit is subject to the September 1993 rules for municipal solid waste landfills (15A NCAC 13B .1600). Pitt County monitors the Northern Unit in accordance with the conditions of the solid waste permit and 15A NCAC 13B .0500. 1.2 Physical Setting and Hydrogeology The Pitt County Landfill lies in the central portion of the Coastal Plain Physiographic Province of North Carolina where Cretaceous to Recent age Coastal Plain sedimentary formations overlie Mesozoic and older basement bedrock (Horton and Zullo, 1991). Coastal Plain sediments and sedimentary rocks have significant variations in permeability and water -producing capabilities. High -permeability strata that readily produce usable quantities of water are aquifers, and low - permeability sediments that restrict the movement of groundwater, either into or out of aquifers, are confining beds. Coastal Plain aquifers typically use the predominant geologic formation name that is associated with the aquifer. The two uppermost aquifers at the Pitt County Landfill are: the unconfined Surficial/Yorktown aquifer and the confined Peedee Aquifer. The Surficial/Yorktown Aquifer is locally composed of fossiliferous clays and sands. The clays within the unit tend to serve as confining layers and restrict recharge to underlying aquifers (GMA and McGill, 2001). The Peedee Aquifer consists of unconsolidated sands and sandstones of the of Late Cretaceous age Peedee Formation (Winner & Coble, 1996). In the western half of Pitt County, the Peedee Aquifer lies directly beneath the Surficial/Yorktown Aquifer, and the elevation of the top of the Peedee Aquifer is above sea level (GMA and McGill, 2001). A detailed description of the local site hydrogeology is provided in the Water Quality Monitoring Plan for the Southern Unit (GMA, 1994). In general, a sandy clay extends from the original land surface beneath the landfill to varying depths of 6 to 13 feet. A portion of this clay may have been excavated from adjacent to the Southern Unit mound and used as part of the clay cap for the mound. Coarser, more permeable sediments (silty fine sand, clayey sand, and very clayey sand) typically exist at depths of 10 to 16 feet. Underlying these more permeable sediments, at a depth of approximately 16 feet below the original land surface, is a thin, discontinuous, dark gray clay that ranges from 0.5 to 3.0 feet in thickness, with an average thickness of 1 foot. This clay layer exists at an elevation of approximately 66 feet above mean sea level and has January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 3 of 14 previously been referred to as the "66-foot clay" (GMA, 1994). Below this clay layer lie silty, fine sands. During the installation of deep monitoring well P20D, GMA observed a silty, clay layer from approximately 45 to 48 feet below the land surface. Below this clay layer, GMA observed a fine, phosphatic sand. GMA believes the deepest on -site monitoring wells (e.g. MW1R, MW3, and P20D) may penetrate the top of the Peedee Aquifer, which is estimated to be about 25 feet thick at the location of the landfill (GMA and McGill, 2001). We provide a general summary of the stratigraphy below. Average depth of strata relative to original land surface (feet) Lithology 0 — 9.5 sandy clay 9.5 — 16 silty fine sand, clayey sand, and very clayey sand 16 — 17 dark gray clay 17 — 45 silty, fine sand 45 — 48 silty, clay 48 — 60+ fine, phosphatic sand 1.3 Contaminants of Concern and Site Regulatory Status As described in the introduction, the Southern Unit of the Pitt County Landfill is currently under assessment for low-level exceedances of the NC Groundwater Quality Standard (NCAC 02L) for benzene. The County first confirmed a slight exceedance of the NCAC 02L groundwater standard for benzene in 2017. Since that time and following approval from the NCDEQ, DWM, SWS, the County has collected groundwater samples from just beneath the southern ditch to monitor the extent of benzene contamination at the facility. This ditch serves as the groundwater discharge location for the Surficial Aquifer at Southern Unit. To date, the County has not detected benzene in exceedance of the NCAC 02L standard in these samples, which suggests that benzene contamination above the NCAC 02L groundwater standard does not extend off the facility property. Pitt County is also currently assessing the Southern Landfill Unit for exceedances of the NCAC 02L standard for 1,4-dioxane. In May 2018, the NCDEQ DWM SWS directed all North Carolina landfills to begin testing for 1,4-dioxane as part of their routine groundwater monitoring. 1,4- Dioxane is used primarily as a chlorinated solvent stabilizer, but it can also be found in paint strippers, varnishes, waxes, and a variety of consumer products (US EPA, 2014). 1,4-Dioxane is fully miscible in water, and it migrates readily with groundwater. This compound is short-lived in the atmosphere, but it does not volatilize rapidly from water. 1,4-Dioxane was detected at the landfill in July 2019, and the County immediately and voluntarily chose to perform an updated potential receptor investigation to determine if any water -supply wells might be at risk. Pitt County opted to conduct the potential receptor survey January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 4 of 14 as a proactive measure in the interest of public health. The updated potential receptor survey, conducted by GMA in September 2018, did not identify any well being used as a drinking water source within 2,000 feet of the facility (GMA, 2018). Exceedances of the NCAC 02L groundwater standard for 1,4-dioxane were confirmed at the Southern Unit of the Pitt County Landfill in January 2019. GMA suspects that the detection of 1,4-dioxane in multiple monitoring wells adjacent to the Southern Landfill Unit relates to degradation of the integrity of one or both landfill caps and the stormwater drainage systems designed to quickly shunt surface water off the landfill mounds. Pitt County emplaced the clay caps above the Landfill in the mid-1990s. Over time, erosion of the cap, as well as cracking due to heating/cooling, desiccation, and/or subsidence due to decomposition of fill material, can increase the permeability of this type of barrier. Cap degradation has likely allowed infiltration of water that has leached contaminants downward into the underlying groundwater. Eliminating infiltration of water through the cap, and ensuring that the stormwater conveyance system operates as designed, are primary goals for reducing, or eliminating, the release of additional contaminants into the groundwater. GMA, on behalf of the County, submitted a proposal to the SWS on June 21, 2019 to further assess and address 1,4-dioxane contamination at the landfill. Specifically, we proposed to: 1) Delineate the vertical and horizontal extents of 1,4-dioxane by installing two additional groundwater monitoring wells (one Type II monitoring well located between the two landfill units and one double -cased, deep Type III monitoring well south of the Southern Mound) and six surface water staff gauges. 2) Conduct a pilot study to document and establish the effectiveness of cap upgrades and repairs to limit the infiltration of rainwater through the soil cap, and to evaluate if the repairs have reduced leachate volumes and contaminant concentrations. During the pilot study, the County proposed to: a) conduct geophysical testing of the Southern Unit to evaluate landfill cap integrity, b) repair any areas of concern identified by the geophysical testing, c) inspect surface water drainage structures on the mound to ensure that they are operating as designed, and then d) repeat geophysical testing after cap repairs are made to document the results of the cap repairs. 3) Install two in -stream piezometers approximately 1.5 feet below the ditch bottom at the locations of the currently collected porewater samples. The in -stream piezometers provide repeatable locations to collect representative groundwater samples, measure groundwater levels, and determine any discharge relationships just below the stream bed. January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 5 of 14 The NCDEQ-SWS approved the proposed activities on June 26, 2019 (Appendix A), and the County immediately began to implement the pilot study. We provide an update regarding the status of the approved activities in Section 2.0 below. 2.0 1,4-DIOXANE ASSESSMENT AND PILOT STUDY UPDATE North Carolina Administrative Code 15A NCAC 13B .1634 requires the County to characterize the nature and extent of any release. The County began assessing the horizontal extent of 1,4- dioxane during the January 2019 monitoring event by voluntarily sampling three additional wells that were present at the facility, but no longer part of the required groundwater monitoring program. In June of 2019, the County installed the two monitoring wells and the six surface water staff gauges described in GMA's Pilot Study proposal in June of 2019. A single -cased (Type -II) monitoring well was installed between the Northern and Southern mounds, just north of well P16R (Figure 1). This well, designated as well P29, is hydrologically separated from well P16R by two drainage ditches along the railroad, and the well is screened from 7 to 12 feet below the land surface. A 60-foot-deep, double -cased (telescoping, Type -III) groundwater monitoring well was installed on the south side of the Southern Unit, just off the toe of the slope of the Southern Mound (Figure 1). This well, designated as well P20D, allowed the County to further assess the vertical extent of 1,4-dioxane at the Southern Unit. The outer casing of P20D extends to 45 feet below land surface, and the well is screened from 50 to 60 feet below land surface. In accordance with the approved Pilot Plan, in August 2019, GMA also installed two shallow, in - stream piezometers (PZ1 and PZ2) below the ditch bottom along the southern property boundary near the locations of the historically collected porewater samples (Figure 1). Each piezometer has a 9-inch-long screen, with the top of the screen set 1 foot below the ditch bottom. The County uses the instream piezometers to collect representative groundwater samples to monitor benzene migration and to evaluate groundwater discharge relationships to the ditch. To evaluate the integrity of the Southern Landfill Unit cap, and to provide a baseline from which to evaluate hydrologic improvements following cap upgrades and repairs, Geo Solutions Limited, Inc. completed electromagnetic (EM) and ground -penetrating radar (GPR) surveys of the Southern Landfill Unit on June 26t", July 1st and July 2"d 2019 (GMA, 2019). The EM survey identified multiple areas of elevated apparent conductivity that may correspond to leachate moving away from the landfill. Additionally, the EM survey indicated that solid waste appears to extend beyond the toe of the slope to the edge of the gravel road in the proximity of monitoring January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 6 of 14 wells MW6R, P16R, and P20R. This finding was consistent with GMA's observations of trash during the installation of well P20D. The GPR survey identified several areas that had only a thin landfill cap that was completely eroded away in some locations. The identified areas included the northwestern upper slope of the mound, the western narrow berm, and the southern toe north of monitoring wells P28 and P19. The GPR results indicated that the impermeable cap thickness at the Southern Landfill was, on average, 10 inches and ranged from 0 to 30 inches. Full details of the geophysical evaluation can be found in Geo Solutions' report, which was provided as Appendix F of the July 2019 monitoring report from GMA (GMA, 2019). A revised version of that report is included as Appendix B in the July 2021 South Monitoring Report and Pilot Study (GMA, 2021b). The revised report includes a correction to the estimates of the thickness of the impermeable cap layer based on a corrected understanding of cap construction at the facility. This correction did not affect the implications or conclusions of the original geophysical evaluation. After completion of the geophysical survey, the County contracted with an engineering firm (The Wooten Company) to design cap repairs and stormwater upgrades that will eliminate or greatly reduce the infiltration of precipitation into the Southern Unit. The County provided the geophysical report to Wooten to aid their design of cap repairs and stormwater upgrades for the facility. The Wooten Company (Wooten) resurveyed the Southern Landfill Unit in early 2020, and in June 2020, Wooten submitted a final design to the County. This design included repairing the cap on the western end of the Southern Landfill, regrading multiple areas to eliminate ponding on the mound, restoring the stormwater conveyance system to operate as originally designed, and adding new drainage pipes to the southwest corner of the mound. The County chose to make these substantial upgrades to protect the groundwater from further contamination via leaching from landfill waste. Construction activities commenced at the site on November 4, 2020. The County's contractor originally anticipated completing the work by March 2021, but the project experienced significant weather -related delays due to long periods of high rainfall from December 2020 through February 2021 (NCSCO, 2021). Repairs at the Southern Unit were completed in June of 2021. As -built drawings for the Southern Unit cap repair and stormwater upgrades are provided in Appendix C in the July 2021 South Monitoring Report and Pilot Study (GMA, 2021b). Following completion of the cap repairs and stormwater system upgrades, GMA contacted Geo Solutions Limited, Inc. to complete a post -repair geophysical evaluation of the Southern Unit. The purpose of this evaluation was to document the remedial effort of the Pitt County Landfill by comparing the pre -repair and post -repair geophysical data. Geo Solutions completed repeat EM and GPR surveys of the Southern Landfill Unit on August 2"d thru August 4t", 2021 (GMA, 2021b). January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 7 of 14 A comparison of the EM response before and after cap improvements showed a weaker EM response in areas where new low permeability material was placed to repair eroded areas of the cap, and in areas where regrading was performed to improve surface water drainage toward the catch basins (Figure 2). The weaker EM response in these locations was due to the EM profiler being further above the waste following repairs. Based on GPR data, the most apparent changes in landfill cap thickness from 2019 to 2021 are along the northern repaired slope where the cap was significantly thickened (15 to 20 inches) during the recent repair (GMA, 2021b). The areas of leachate seeps identified in 2019 appeared similar in EM response to the 2021 electromagnetic survey. It is likely too soon to see improvements at seep locations due to the slow velocity of groundwater at this site. Future geophysical evaluations targeting only the locations of previously identified seeps may provide a means to monitor the effectiveness of the recently completed cap improvements. Regardless, geophysical results confirm improvements to the landfill cap thickness and surface water drainage that should greatly reduce the infiltration of precipitation into the Southern Landfill Unit. The County is currently monitoring groundwater levels and contaminant concentrations to assess the effectiveness of the cap and stormwater system upgrades, as approved by the NCDEQ-SWS in their June 26, 2019 letter (Appendix A). An extension of the pilot study through July 2023 was approved by the NCDEQ Division of Waste Management, Solid Waste Section, in a letter dated November 15, 2022. The County will continue monitoring until at least July 2023 to allow time for the existing groundwater to drain from the Southern mound prior to making a full assessment of hydraulic improvements resulting from the repair of the Southern cap. The County continues to monitor both the Northern and Southern Landfill Units on their approved schedules (semi-annually for the Southern and annually for the Northern). 3.0 JANUARY 2023 SEMI-ANNUAL MONITORING EVENT GMA performed the semi-annual monitoring event at the Southern Unit on January 18 to 19, 2023. Historically, the County has monitored the Southern Landfill Unit for the parameters identified in Appendix I of 40 CFR Part 258 plus 1,4-dioxane on a semi-annual basis and for the parameters listed in 40 CFR Part 258 Appendix II on an annual basis. Based on the lack of detections of Appendix II parameters over the last 20 years, GMA, on behalf of the County, requested that the NCDEQ SWS allow a reduction in sampling frequency for Appendix II constituents. Specifically, we requested that the NCDEQ SWS allow the County to sample for Appendix II constituents on a biennial basis with the next scheduled Appendix II sampling event occurring during July 2024. The NCDEQ SWS approved this request on July 2, 2020 (Appendix January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 8 of 14 A). Therefore, during the January 2023 monitoring event, the County analyzed all groundwater and surface -water samples for Appendix I parameters and for 1,4-dioxane, but did not analyze for Appendix II parameters. Sampling procedures and analytical methods complied with the approved Water Quality Monitoring Plan dated September 8, 1994, and subsequent groundwater policy memos issued by the NCDEQ-SWS (Appendix A). Twenty-eight groundwater -monitoring wells and two temporary groundwater piezometers comprise the groundwater -monitoring network for the entire landfill facility (Figure 1, Table 1). GMA also monitors surface water levels at thirteen staff gauges in the ditches surrounding the site. The water -quality monitoring network used for the January 2023 semi-annual monitoring of the Southern Unit consisted of two background monitoring wells (P4 and MW1R), seven shallow' wells located around the Southern Mound (P12, P16R, P17, P19, P20R, P28, and MW6R), a 'deep' well located south of the Southern mound (P20D), a well located between the Northern and Southern Landfill Unit (P29), two temporary groundwater piezometers (PZ1 and PZ2), a hydraulically-upgradient surface water sample location (SW1), and a hydraulically- downgradient surface water sample location (SW2) (Figure 3). Monitoring well P11R was removed from the sampling schedule, and monitoring well MW1R was added to the sampling schedule for the January 2023 monitoring event per approval by the NCDEQ DWM SWS in a letter dated November 15, 2022. 3.1 Groundwater Hydrology GMA measured static water levels in all monitoring wells, both temporary piezometers (Table 2), and at 12 of the 13 staff gauges (Table 3) on January 18, 2023. Staff gauge SG5 has been damaged by mowing at the facility and has not been replaced to date. Depth to groundwater in monitoring wells at the site ranged from approximately 1.24 to 13.69 feet below the land surface. Estimates of groundwater velocity (Table 4) ranged from approximately 0.002 to 0.033 feet/day, or 0.77 to 11.89 feet/year. These represent relatively slow groundwater velocities. An equipotential map prepared using these water -level measurements (Figure 3) shows that the horizontal component of groundwater flow at the Southern Unit was generally directed to the south and southeast. A portion of the Northern Landfill Unit lies hydraulically upgradient of the Southern Unit, but the highest groundwater levels at the facility are located offsite, just northwest of the landfill boundary near the Pitt County Solid Waste and Recycling site on Stantonsburg Road. Groundwater samples collected and analyzed from wells (MW1R and P4) in this hydraulically-upgradient area represent background groundwater chemistry. During the January 2023 monitoring event as well as the previous monitoring events in January 2022 and July 2022, the groundwater elevation measured in well P16R was lower than the surface water elevation at the nearby staff gauge, SG3, indicating that groundwater from the January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 9 of 14 Southern mound was not discharging to the ditch at this location. Prior to these three monitoring events, the opposite relationship has been true. Since July 2019 when a staff gauge was first installed at this location, the groundwater elevation in well P16R had consistently been higher than the surface water elevation at SG3, which indicated that shallow groundwater within the Southern Unit was discharging to the ditch in this area. GMA believes that the change in the direction of shallow groundwater flow at this location may be the beginning indications of hydraulic improvement resulting from the cap repairs and stormwater improvements completed at the Southern Unit. Further monitoring and assessment is needed to determine if this relationship continues in the future or whether this is due to seasonal and/or annual variation in rainfall. The groundwater elevations at instream piezometers PZ1 and PZ2 were slightly higher than the surface water elevation during the January 2023 monitoring event (Tables 2 and 3). The water level measurements collected at PZ1 and PZ2 indicates that groundwater was discharging to the southern boundary ditch in this area during the January 2023 monitoring event. 3.2 Sample Collection and Analyses For monitoring of the Southern Unit, GMA analyzed water samples collected from eleven monitoring wells, two temporary piezometers, and two surface water sampling locations as shown on Figure 2. During sampling, GMA collected field water -quality parameters to document adequate purging prior to sample collection and to aid in evaluating groundwater chemistry at the site (Table 5). We provide copies of the well sampling records in Appendix B. Sampling procedures and analytical methods complied with the approved Water Quality Monitoring Plan dated September 8, 1994, and subsequent directives issued by the SWS (Appendix A). GMA transferred all samples to Environmental Conservation Laboratories, Inc. (ENCO) in ice - filled coolers under chain -of -custody protocol for analysis of Appendix I parameters and 1,4- dioxane (Table 6). Copies of the chain -of -custody forms and analytical reports are provided in Appendix C. Consistent with the May 29, 2018 NCDEQ-SWS memo, ENCO analyzed the samples using EPA -approved analytical methods sufficiently sensitive to detect the presence of regulated constituents at or below the applicable standard (unless no such method currently exists, e.g. for vinyl chloride analysis). 3.3 Analytical Results and Discussion Twenty-nine parameters (acetone, arsenic, antimony, barium, benzene, beryllium, bromodichloromethane, 2-butanone, carbon disulfide, chlorobenzene, chloroform, chromium, cobalt, copper, 1,4-dichlorobenzene, 1,1-dichloroethane, cis-1,2 dichloroethane, 1,4-dioxane, January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 10 of 14 ethylbenzene, lead, m,p-xylenes, nickel, o-xylene, selenium, toluene, vanadium, vinyl chloride, total xylene, and zinc) were detected at concentrations above their method detection limits during the January 2023 sampling event (Table 7). Five of those constituents (barium, benzene, chromium, 1,4-dioxane, and vinyl chloride) were detected at concentrations exceeding the NCAC 02L standard, and three parameters (beryllium, cobalt, and vanadium) were detected at concentrations above their Interim Maximum Allowable Concentration (IMAC) during this monitoring event (Table 7). Samples from wells P16R, P19, and P20R contained benzene (2.3 µg/L, 3.6 µg/L, and 2.3 µg/L respectively) above the 1.0 µg/L NCAC 02L groundwater standard. Importantly, benzene was not detected in either in -stream piezometer sample (PZ1 and PZ2). Therefore, there continues to be no evidence that benzene is migrating off of the landfill property at this time. 1,4-Dioxane was detected in wells MW6R, P16R, P17, P19, P20R, and P29 (6.7 µg/L, 78 µg/L, 3.6 µg/L, 150 µg/L, 84 µg/L, and 53 µg/L, respectively) at concentrations exceeding the NCAC 02L groundwater standard of 3.0 µg/L. The detection of 1,4-dioxane in well P29 located between the two landfill units indicates that 1,4-dioxane may be leaching from both the Southern and Northern mounds. 1,4-Dioxane was also detected in the downgradient surface water sample SW2, in the southern ditch, but the concentration was below the NCAC 02B surface water standard. Incongruently, the lab did not detect 1,4-dioxane in the sample collected from the "deep" down -gradient monitoring well P20D. Low level concentration of 1,4- dioxane was detected in well P20D for the first time in the previous July 2022 sampling event (GMA, 2022b). Samples from wells MW6R, P16R, P19, and P20R contained concentrations of barium (2000 µg/L, 880 µg/L, 1800 µg/L, and 940 µg/L respectively) above the NCAC 02L standard of 700 µg/L. Barium occurs naturally in the native soils at the Pitt County Landfill as evidenced by the ubiquitous occurrence of this alkaline metal in all samples collected at the site, including those located in up -gradient off -site areas. GMA has previously demonstrated that barium is often a constituent of the particulate matter in many of the groundwater samples collected at the Pitt County Landfill and that dissolved barium concentrations do not exceed the NCAC 02L standard in some locations (GMA, 2011 and 2015). Despite the apparent natural occurrence of barium at this site, the concentrations of barium detected in wells MW6R and P19 are unlikely to be solely attributable to natural sources. Chromium was detected in the "deep" down -gradient monitoring well P20D (11 µg/L) exceeding the NCAC 02L standard of 10 µg/L. In recent years, concentration levels of chromium at well P20D have fluctuated above and below the NCAC 02L standard (GMA 2020b, 2021a, 2021b, 2022a, and 2022b). Low level concentration of chromium was detected in down -gradient surface water sample SW2, but the concentration was below the NCAC 02B surface water January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill April 18, 2023 Page 11 of 14 standard. The lab did not detect any of the target parameters above the 2B surface -water standards in any surface water samples for the Southern Unit (SW1 and SW2). Low, estimated (i.e.'Tflaggefl concentrations of vinyl chloride was detected in the "shallow" down -gradient monitoring well P19 (0.43 J µg/L) exceeding the NCAC 02L standard of 0.03 µg/L. In recent years, concentration levels of vinyl chloride at well P19 have consistently been detected above the NCAC 02L standard. Zinc, copper, chloroform and carbon disulfide were detected in the equipment blank. GMA believes that zinc concentrations are related to residual powder from the manufacturing process used to produce the powder -free' nitrile gloves that we used during sampling. Nitrile gloves are also the likely source of the carbon disulfide detected in the equipment blank (USGS, 2012). Chloroform is a common laboratory contaminant related to the cleaning of glassware, equipment, etc. (USEPA, 2014b). The source of copper in the equipment blank is unknown. GMA will review sampling procedures before the next groundwater sampling event. 4.0 CONCLUSIONS AND FUTURE WORK 1,4-Dioxane, barium, benzene, chromium, and vinyl chloride were detected at concentrations exceeding the NCAC 02L groundwater standards at multiple locations during the January 2023 monitoring event. However, these constituents were not detected at concentrations above state standards in groundwater samples collected from just below the southern property ditch, which acts as a local groundwater discharge feature, or in the downgradient surface -water sample. These results suggest that the contaminants of concern (1,4-dioxane, benzene, and concentrations in excess of naturally occurring barium) are not migrating off -site at this time. Further, neither 1,4-dioxane nor benzene were detected in the sample collected from the deep monitoring well located down -gradient of the Southern Landfill Unit (1320D). Barium was detected in this well, but the concentration (80.0 ug/L) was well below the NCAC 02L standard of 700 ug/L, and below concentrations detected in upgradient, off -site monitoring wells. The absence of these target compounds indicates that 1,4-dioxane, benzene, and non-native barium have not migrated out of the Surficial/Yorktown Aquifer at the site. In June 2021, the County completed the planned cap and stormwater system repairs and upgrades at the Southern Unit (GMA, 2021b). These upgrades were part of an approved pilot study for corrective action following detections of 1,4-dioxane and benzene above the NCAC 02L groundwater standards. These improvements were designed to greatly reduce the infiltration of water through the cap in order to protect the groundwater from further contamination via leaching from landfill waste. The County is currently monitoring groundwater levels and contaminant concentrations to assess the effectiveness of the cap and stormwater January 2023 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal tandfill April 18, 2023 Page 12 of 14 system upgrades, as approved by the NCDEQ-SWS in their June 26, 2019 letter (Appendix A). Lower water elevations in well P16R compared to the adjacent ditch (SG3) (tables 2 and 3), continue to show a reversal of shallow groundwater flow in the vicinity of well P16R since the cap and stormwater system upgrades (GMA 2022a and 2022b). This trending change in flow direction away from the ditch further indication of hydraulic improvement associated with the cap repairs at the Southern Unit, but further assessment is needed. An extension of the pilot study through July 2023 was approved by the NCDEQ Division of Waste Management, Solid Waste Section, in a letter dated November 15, 2022, to allow time for the existing groundwater to drain From the Southern mound prior to making a Full assessment of hydraulic improvements resulting From the cap repair. At present, it is too soon to see reductions in contaminant levels associated with the cap repairs. The County continues to monitor groundwater at the Southern Unit on a semi-annual schedule. The next semi-annual monitoring event at the Pitt County Solid Waste Municipal Landfill is scheduled for July of 2023 and will include Appendix I parameters plus 1,4-dioxane. 5.0 REPORT CERTIFICATION This report was prepared by Groundwater Management Associates, Inc.

Within the Pilot Study Update and Request foran Extension of the Pilot Study, Pitt County is requesting approval of three monitoring requests: • First, to address the 1,4-Dioxane detected in the groundwater, the County completed a cap improvement project with geophysical surveys and stormwater system upgrades as part of an approved pilot study that began in 2019 for groundwater corrective action (FIDs 1323159 and 1323161). Continued monitoring is needed to assess the effectiveness of the upgrades so the County is requesting an extension of the pilot study until July 2023. • Second, the County is requesting to remove wells P5, P6, and P9 from the Northern Unit and P11R from the Southern Unit from routine monitoring. Groundwater levels will continue to be collected from these wells. • Finally, the County is requesting to add well MW1R to the routine monitoring schedule for the Southern Unit. Based upon a review of the Pilot Study Update and Request for an Extension of the Pilot Study, the Section approves the requests as written at this time.

To address the 1,4-Dioxane being detected within the groundwater at the landfill, Pitt County is proposing to: 1) Delineate the vertical and horizontal extent of 1,4-Dioxane by installing two additional groundwater monitoring wells (Type II and Type III) and six surface water gauges; 2) Initiate a one-year pilot study to determine the effectiveness of cap upgrades and repairs to see if they have limited the infiltration of rainwater into the soil cap, and if they have reduced leachate volumes and concentrations. Geophysical testing of the Southern Unit only will also be conducted to evaluate landfill cap integrity. The County will repair any areas identified by the geophysical testing and will inspect surface water drainage structures on the mound to ensure that they are operating as designed. Once repairs are made, geophysical testing will be repeated to document hydrologic benefits from cap repairs and to determine if the repairs have significantly reduced rainfall infiltration; and 3) Install two instream piezometers approximately 1.5 feet below the ditch bottom at the locations of the currently collected porewater samples. The instream piezometers will be used to collect representative groundwater samples, measure groundwater levels, and determine any discharge relationships at repeatable locations just below the stream bed. Based upon a review of the Proposal for 1,4-Dioxane Assessment and Pilot Study at the Pitt County Municipal Solid Waste Landfill, the Section approves the activities as described.

Receipt The samples were received on 1/23/2023 10:00 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 6.00 C. GC/MS VOA Method 8260D: The laboratory control sample (LCS) & laboratory control sample duplicate (LCSD) for analytical batch 752-707 recovered outside control limits for several analytes. A MRL (reporting limit) sample was analyzed and all analytes were detected. The client samples with detects will be reanalyzed for those compounds. Method 8260D: The continuing calibration verification (CCV) associated with batch 752-708 recovered outside acceptance criteria, low biased, for several compounds. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Non -detections of the affected analytes are reported. Any detections are considered estimated. Method 8260D: The continuing calibration verification (CCV) associated with batch 752-708 recovered above the upper control limit for several compounds. Non -detections of the affected analytes are reported. Any detections are considered estimated. Method 8260D: The laboratory control sample (LCS) and/ or laboratory control sample duplicate (LCSD) for analytical batch 752-708 recovered outside control limits for the following analytes: 1,2-Dichlorobenzene, 2-Butanone (MEK), Acetone, Bromoform, Chlorobenzene, m-Xylene & p-Xylene, o-Xylene, Styrene and 1,4-Dichlorobenzene. Method 8260D: The CCV for analytical batch 752-707 recovered outside control limits for the following analyte(s): 1,2-Dibromo-3-Chloropropane, 2-Butanone (MEK), 2-Hexanone, 4-Methyl-2-pentanone (MIBK), Acetone, Acrylonitrile, Bromomethane, Chloroethane, Chloromethane, Vinyl acetate and Vinyl chloride have been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified. Method 8260D: The method blank for analytical batch 752-872 contained 2-Butanone (MEK) above the method detection limit (MDL). Associated samples were not re -analyzed because results were less than the reporting limit (RL) OR practical quantitation limit (PQL). 2-Butanone limits have recently increased to a reporting limit (RL) of 20ug/L. Method 8260D: The following analytes have been identified, in the reference method and/or via historical data, to be poor and/or erratic performers: 2-Butanone (MEK), Acetone, Chloroethane and Vinyl acetate. These analytes may have a 50% D. Method 8260D: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for analytical batch 752-872 recovered outside control limits for the following analyte(s): 2-Butanone (MEK). 2-Butanone (MEK) has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. Method 8260D: The LCS & LCSD was biased low for Styrene. The compound was a non -detect in the client samples. Styrene was detected in the MRL sample; therefore, the data were reported. (LCS 752-872/4) and (LCSD 752-872/5) Method 8260D: The continuing calibration verification (CCV) associated with batch 752-872 recovered outside acceptance criteria, low biased, for 1,1,2,2-Tetrachloroethane, Vinyl chloride and 1,4-Dichlorobenzene. A reporting limit (RL) standard was analyzed, and the target analytes are detected. Since the associated samples were non -detect for the analyte(s), the data are reported.
