The Site consists of two properties, the facility where the former Seaboard Chemical Corporation (Seaboard) conducted operations (the Seaboard Facility) and the closed municipal Riverdale Drive Landfill (Landfill), as shown on Figure 2. The Seaboard Facility is located at 5899 Riverdale Drive, Jamestown, NC and consists of approximately 13 acres. Between 1974 and 1989, Seaboard operated solvent recovery and fuel blending processes at the facility. The corporation declared bankruptcy in 1989 and was not able to fund the cost of performing the necessary site closure and remediation. Removal activities were conducted during 1990 and 1992 to remove all remaining waste materials and certain tanks and equipment from the Seaboard Facility. The removal was conducted by Seaboard Group I which was formed by parties that may have used the services of Seaboard in the past. The adjacent Landfill, a closed unlined municipal solid waste landfill, consists of approximately 150 acres and bounds the Seaboard Facility on two sides. The Landfill was operated from the 1950’s until October 1993. The Landfill was permitted by the North Carolina DEQ Solid Waste Section in 1979. During Landfill operations, sections of the two tributary streams that cross the landfill property were piped and solid waste was used to fill the drainage valleys. The two streams are referred to as the Southern Intermittent Stream and the Northern Intermittent Stream. During filling of the Southern Intermittent Stream valley, a leachate collection system was installed adjacent to the stream channel to collect leachate migrating from the overlying solid waste. In 1989, a leachate collection system was added to control surface seeps (leachate leaks) along the Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 2 slopes of the Landfill. From approximately 1966 to 1970, Landfill operations also included the disposal and open burning of spent solvents in shallow pits located just north of the former Landfill scale house (Figure 2). Periodically, these burn pits were cleaned of residue that accumulated in a mound to the south of the burn pits. Presently, this mound consists of approximately 600 cubic yards of contaminated residue capped by a synthetic liner and is referred to as the “soil residue mound”. The Landfill is now capped and maintained under an approved post-closure plan. Seaboard Group II was formed in 1994 and entered into an agreement with the City of High Point (the City) to jointly perform a remedial investigation and prepare a baseline risk assessment and feasibility study for the Site, including both the closed Seaboard Facility and Landfill. The Seaboard Group II and the City then entered into an Administrative Order on Consent (AOC) dated January 30, 1996 with NC DEQ to perform the remedial investigation. The feasibility study was conducted under a separate AOC dated July 22, 1997. Remedial investigations conducted at the Site have documented the presence of chlorinated and non-chlorinated volatile organic compounds (VOCs) in soils, Landfill leachate, groundwater, and surface water. The remedial investigation results indicate that the VOC-affected groundwater is migrating to Randleman Lake, which adjoins the Site along the northern and eastern property boundary of the Landfill. The Randleman Lake was created by the impoundment of the Deep River in 2006 by the Randleman Lake Dam, which is located approximately 11.5 miles downstream of the Site. The Remedial Recommendation Document (February 2005) presented a remedial strategy for the impacted media at the Site based on the results of the remedial investigation, baseline risk assessment, and feasibility study. The remedial design consisted of groundwater extraction and treatment in combination with institutional controls including site access control, recorded land use restrictions, and restriction of water Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 3 supply well construction. The groundwater and surface water monitoring program is designed to evaluate the effectiveness of the remedy. The Remedial Recommendation Document was conditionally approved by the NC DENR in September 2005. Seaboard Group II and the City entered into a Remedial Action Settlement Agreement (RASA) with NC DEQ on December 29, 2008. The RASA provides for the design and implementation of the approved remedial action program for the Site as well as completion and reporting of annual groundwater and surface water monitoring activities. 1.2 Site Geology The Site is located in the central Piedmont Physiographic Province, in the northern portion of the Carolina Slate Belt. Granite is the predominant rock type in the area and outcrops are observed along the creeks and within the Site. The geology of the Site consists of fractured granitic gneiss which has been intruded by mafic dikes. The mafic dikes are generally oriented N20oE and are sub-vertical, dipping to both the northwest and the southeast. The mafic dikes generally do not occur as single massive tabular bodies, but normally occur as a swarm of thinner tabular and/or irregular dikes within larger fracture zones within the granitic gneiss. The thickness of individual mafic dikes ranges from less than one foot to more than 30 feet. Smaller mafic dikes that are not associated with fracture zones are disseminated throughout the granitic gneiss. Several prominent geologic structures have been identified and mapped at the Site, including these significant geologic features: Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 4 Southern Intermittent Stream Fault - N80oE oriented fracture zone/fault that parallels the Southern Intermittent Stream. Based on an on-site outcrop measurement and fracture orientation data from the PW-3D core, the fracture zone is believed to dip 43o to the south; Seaboard Dike – N20oE oriented mafic dike that extends from the Seaboard Facility to the vicinity of monitoring well PW-13I and north of the Deep River; PW-5D Dike/Fault – N20oE oriented diabase dike /fault that extends northward from the east side of the Seaboard Facility near PW-8S to the vicinity of monitoring well PW-5D north of the Deep River. The PW-5D Fault has an inferred connection with the Southern Intermittent Stream Fault beneath the Landfill; Regional Fault/Dike – major regional fault/mafic dike that extends N20oE near PW-6I/6D and extends north of the Deep River; and Deep River Fault – southward-dipping fault that forms the east-west segment of the Deep River. Based on an on-site outcrop measurement and fracture orientation data from the PW-5D core, the fracture zone is believed to dip 50o to the south. 1.3 Site Hydrogeology The Site hydrogeology is characteristic of the regional piedmont aquifer system and consists of three aquifer units: the saprolite and partially weathered rock (PWR) aquifer, shallow bedrock aquifer, and deep bedrock aquifer. The saprolite/PWR aquifer is the uppermost aquifer across much of the Site, but is locally absent where the water table occurs below the top of bedrock. The thickness of the saprolite/PWR aquifer, where present, is generally less than 20 feet but extends to depths of 90 feet in limited areas Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 5 (PW-13I). The shallow bedrock aquifer extends from the top of competent bedrock to a depth where groundwater flow becomes limited due to the lack of open fractures. The base of the shallow bedrock zone at the Site is variable but generally believed to occur at depths of 200 to 400 feet. The deep bedrock aquifer extends downward from the base of the shallow bedrock aquifer and is characterized by low permeability and limited groundwater flow. The primary zone of groundwater movement at the Site is considered to occur within the saprolite/PWR and shallow bedrock aquifer zones. The saprolite/PWR and shallow bedrock aquifers are hydraulically connected. The potentiometric surface of shallow groundwater in the saprolite/PWR aquifer is generally a subdued replica of the original topography of the Site. The saprolite/PWR aquifer is locally absent where the water table occurs below the top of bedrock (generally beneath the topographic highs). Groundwater flow within the shallow bedrock aquifer is primarily through fractures in the bedrock and is strongly controlled by subsurface geologic structures such as faults, fracture zones, and mafic dikes. Based on the results of two constant rate discharge tests conducted in August and September 1997, the calculated bulk hydraulic conductivity values at the Site range from 0.5 to 3 feet/day (ft/d) in the saprolite/PWR aquifer zone, and 0.1 to 0.6 ft/d in the shallow bedrock aquifer zone. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 6 2.0 Water Quality Monitoring Program The water quality monitoring network at the Site is evaluated on an annual basis. The locations of the groundwater and surface water samples collected during the annual monitoring event are shown on the attached Figure 2. The primary objectives of the annual groundwater and surface water monitoring program are:  Monitor VOC concentrations and migration of the VOC-affected groundwater;  Monitor groundwater elevations, hydraulic gradients and flow directions;  Monitor surface water quality in Randleman Lake, Northern Intermittent Stream, and Southern Intermittent Stream to assess impacts from groundwater discharge. The 2017 annual groundwater and surface water monitoring activities were conducted at the Site during the period of October 10-17, 2017. Groundwater level gauging was conducted at the monitoring wells to be sampled to evaluate groundwater flow patterns at the Site (Figure 2). Surface water sampling was conducted at nine surface water stations which included; four stations along Randleman Lake (SW-6, SW-7, SW-DRP-2, and SW-DRP-11), three stations on the Southern Intermittent Stream (SW-3, SW-4, and SW-5), and two monitoring stations on the Northern Intermittent Stream (SW-1 and SW-2). Please note that surface water station SW-1 was dry at the time of this monitoring event and no sample was collected. 2.1 Groundwater Monitoring Network The existing groundwater monitoring network consists of 25 monitoring wells which have been selected to evaluate the lateral and vertical extent of the contaminant plume as well as the effectiveness of the groundwater extraction system. The 25 monitoring wells sampled for subsequent laboratory analysis include: Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 7 MW-1 (background) MW-3C MW-6 MW-10 MW-12A MW-12B MW-12D MW-15A OW-DR2 OW-LFS2 PW-3D PW-4I PW-5D PW-6I PW-6D PW-10I PW-10D PW-12I PW-13I PW-14D PW-15D PW-16D PW-18 PW-SF1 W-4A Monitoring well construction information and groundwater elevations for wells at the Site are provided on Table 1. 2.2 Surface Water Monitoring Network The current surface water monitoring network consists of nine monitoring stations as shown on Figure 2. The surface water monitoring stations are located along the northern and southern intermittent streams, and on the Randleman Lake. The nine surface water stations sampled for the water quality monitoring program include: SW-1 SW-2 SW-3 SW-4 SW-5 SW-6 * SW-7 * SW-DRP-2 * SW-DRP-11 * * The surface water samples collected from the Randleman Lake are collected at two discrete depths, 1’ below the surface and 1’ above the bottom of the Lake. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 8 3.0 Water Quality Sample Collection Samples of groundwater and surface water were collected in accordance with the approved Annual Monitoring Plan – 2010 dated March 17, 2010. A brief description of the sample collection procedure is provided below. The 2017 annual groundwater and surface water monitoring activities were conducted at the Site during the period of October 10 - 17, 2017. 3.1 Field Sample Procedures Prior to groundwater sampling, water levels were obtained from each well using an electric water level meter capable of measuring the depth to water to the nearest 0.01 feet. This information was later used to determine the elevation of the water table in each monitoring well relative to surveyed datum (Table 1). The depth to water in each well was also used to determine the volume of standing water in the well casing. This information allowed for the purging of a minimum of three casing volumes from each well prior to sample collection to assure a fresh groundwater sample was collected. New nitrile gloves were worn by sampling personnel and each well was purged and sampled with a decontaminated submersible pump or a new disposable bailer which was discarded after use. After the monitoring wells had been allowed to recover from purging, normally 12-14 hours, samples were collected in the following order:  VOCs and 1,4-dioxane  Field parameters (pH, conductivity, temperature, and dissolved oxygen) The samples were collected directly in the laboratory-supplied containers which had been pre-filled with the appropriate preservative. No filtering of the samples was performed. After collection, the samples were placed in a cooler on ice for shipment to the analytical laboratory. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 9 Surface water samples were collected directly into the laboratory-supplied containers as grab samples. Sampling personnel wore new disposable nitrile gloves for each surface water sample collected. The surface water samples collected from the four stations along the Randleman Lake were collected at two discrete intervals: a shallow sample collected 1 foot below the surface, and a deeper sample collected 1 foot above the bottom of the Lake. The Randleman Lake water samples were collected using a stainless steel discrete- interval Kemmerer water sampler. The actual depths of the shallow and deeper Randleman Lake surface water samples are provided in Table 4. As with the groundwater samples, these samples were stored in a cooler on ice prior to delivery to the analytical laboratory. 3.2 Field Quality Assurance Three trip blank samples were prepared by the analytical laboratory and accompanied the sample shipments until receipt by the laboratory. The trip blank samples were analyzed for VOCs. Temperature blanks were also provided with the sample shipments to assure the proper temperature was maintained until delivery to the analytical laboratory. 3.3 Sample Delivery/Chain of Custody All groundwater and surface water samples were stored in coolers on ice immediately after collection. Individual sample containers for each monitoring well or surface water sample were placed in zip lock plastic bags to reduce the potential for cross contamination between sample locations. Chain-of-Custody control documents were prepared and shipped with each cooler. Custody seals were also used for each cooler to maintain sample integrity until delivery to the analytical laboratory. The sample coolers were shipped via Federal Express for next morning delivery to the analytical laboratory. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 10 4.0 Laboratory Analysis The groundwater and surface water samples were analyzed for VOCs by EPA Method 8260 and 1,4-dioxane by EPA Method 8260C SIM. The laboratory performing the water quality analysis is Environmental Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina, which is a NC Certified Laboratory. Internal quality control samples, including matrix spikes/matrix spike duplicates, were performed by ENCO for each set of samples. The ENCO laboratory report, including internal quality control samples, is provided with this report in Appendix A. Field parameters (pH, specific conductivity, temperature, and dissolved oxygen) were also measured by the sampling personnel for each groundwater and surface water sample using calibrated meters. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 11 5.0 Hydrogeological Conditions The depth to groundwater was measured in the 25 compliance monitoring wells during the October 2017 monitoring event. The groundwater elevations were calculated relative to the surveyed measuring point (top of casing) for each monitoring well. A groundwater potentiometric map is provided as Figure 2. This potentiometric map primarily represents groundwater flow in the bedrock aquifer. The groundwater elevation data for the Site are summarized in Table 1. In the bedrock aquifer, the general groundwater flow direction from the Seaboard Facility is northeastward toward Randleman Lake. The vertical hydraulic gradient in the shallow bedrock aquifer, as measured between monitoring wells MW-3C and OW-DR2 in October 2017, was 0.056 feet/feet downward. In the area across Randleman Lake to the northeast, groundwater elevation data for well PW-18 and other monitoring wells indicate that the horizontal hydraulic gradient is to the south/southeastward, toward Randleman Lake. An Extraction Rate/Capture Zone Test was conducted by ERM NC, PC in August 2002. This test used well PW-DR1 as the primary extraction point to determine the potential capture zone using various pumping rates. Consistent with the results of this test, pumping at a relatively low rate of 10 - 20 gpm from PW-DR1 effectively contains the contaminant plume. The filling of Randleman Lake began in 2006 and the lake level reached normal pool elevation (682 feet msl) in 2008. Based on the data collected during the October 2017 monitoring event, groundwater levels at monitoring wells located adjacent to the lake have risen 10 - 12 feet as compared to pre-lake water level conditions. Inland from the lake, groundwater levels at wells located on the western portion of the Site have risen approximately 4 feet due to the lake impoundment. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 12 6.0 Laboratory Analytical Results Final analytical results for the samples collected during the period of October 10 – 17, 2017 were received from the laboratory on October 26, 2017. A summary of the analytical results are provided for groundwater (Table 2), surface water (Table 3), and field parameters (Table 4). 6.1 Groundwater Analytical Results The analytical results for selected groundwater contaminants collected during the October 2017 monitoring event are shown in a series of figures. Groundwater quality maps are provided for 1,2-dichloroethane (Figure 3), vinyl chloride (Figure 4), chlorobenzene (Figure 5), 1,4-dioxane (Figure 6), and total VOCs (Figure 7) in the bedrock aquifer. The historical groundwater analytical results for specific VOCs, including the 2017 data, are summarized in Table 2 and the ENCO laboratory reports are provided in Appendix A. Measurements of pH, temperature, specific conductance, and dissolved oxygen as determined in the field are provided in Table 4. Additional monitoring well information including the latitude/longitude of each well location is provided in Table 5. The main mass of VOC-affected groundwater generally extends northeastward across the Site to the Randleman Lake basin. As shown on Figure 7, relatively high concentrations of VOCs originate in the vicinity of the northeast corner of the Seaboard Facility near the location of three former surface impoundments. Prior to their closure and capping between 1984 and 1986, the area of the former impoundments served as a primary source area of VOC releases to the groundwater at the Seaboard Facility. Relatively high VOC concentrations in groundwater also originate in the area of the soil residue mound, a contaminant source area located at the Landfill which has also been closed and capped. VOCs were detected in a limited area to the northeast across Randleman Lake from the Site. Concentrations of VOCs and 1,4-dioxane at levels above the respective North Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 13 Carolina 2L Groundwater Quality Standards were detected at off-site bedrock monitoring wells PW-14D, PW-15D, and PW-16D, which are located on the north side of the Randleman Lake basin from the Site. The extent of the VOC contaminant plume on the north side of the Randleman Lake appears to be limited primarily to property encompassed by the Lake’s buffer zone, which is maintained and regulated by the Piedmont Triad Regional Water Authority (PTRWA). It was noted that the total VOC and 1,4-dioxane concentrations in groundwater monitoring well PW-16D had significantly decreased during this monitoring event. A review of the sample collection methodology and laboratory protocol did not identify a possible cause for these analytical results. This well was re-sampled on November 29, 2017 to verify the VOC and 1,4-dioxane analytical results. The results of the re-sampling indicated concentrations of VOCs and 1,4-dioxane are consistent with historic water quality results. While a cause for the initial low contaminant concentrations in monitoring well MW-16D was not identified, the results of the re-sampling event were used for preparation of the contaminant isoconcentation maps. The laboratory analytical results of the initial sample collected from PW-16D and the re-sampling event are provided on Table 2. Overall, the October 2017 groundwater analytical results and the general distribution of VOCs in the Site’s groundwater are consistent with the historical groundwater quality monitoring results. 6.2 Surface Water Analytical Results Surface water sampling was conducted at the Southern Intermittent Stream, Northern Intermittent Stream, and at various locations and depths in the Randleman Lake. The surface water results for VOCs and 1,4-dioxane are summarized in Table 3 and the ENCO laboratory report is provided in Appendix A. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 14 Randleman Lake The Randleman Lake surface water sampling stations include:  SW-6 – Upstream and background sample location for the Site,  SW-DRP-2 – Adjacent to the Site near Lift Station 1 and PW-DR1,  SW-7 – Downstream of the Site at the I-85 bridge, and  SW-DRP-11 – Downstream (~1 mile) at Richland Creek confluence. The compound 1,4-dioxane was reported in all four of the Randleman Lake surface water monitoring stations, including the upstream background sample, during the October 2017 monitoring event. The upstream surface water monitoring station (SW-6) reported shallow/deep 1,4-dioxane concentrations of 13/14 ug/l. The three downstream surface water stations also reported detectable concentrations of 1,4-dioxane above the laboratory reporting limit of 2.0 ug/l. The sample collected from surface water monitoring station SW-DRP-2 reported the shallow/deep concentrations of 1,4-dioxane as 19/21 ug/l. The reported shallow/deep concentrations of 1,4-dioxane at surface water monitoring station SW-7 were 26/20 ug/l. The reported shallow/deep concentrations of 1,4-dioxane at surface water monitoring station SW-DRP-11 were 31/31 ug/l. The North Carolina 2B Surface Water Standard for 1,4-dioxane is 3.1 ug/l. No other VOCs were reported in any of the Randleman Lake surface water samples above the laboratory reporting limits. The locations of the surface water monitoring stations are shown on Figure 2 and a summary of the Randleman Lake surface water analytical results is provided in Table 3. Based on field observations during the October 2017 monitoring activities, the Randleman Lake was approximately two (2) feet below normal pool elevation of 682 feet msl. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 15 Southern Intermittent Stream The Southern Intermittent Stream surface water sampling stations include:  SW-5 – Upstream of Seaboard Facility and downstream of City MRF,  SW-3 – Downstream of Seaboard Facility and upstream of Landfill, and  SW- 4 – Downstream of both Seaboard Facility and Landfill. The compound 1,4-dioxane was reported in all three of the Southern Intermittent Stream surface water monitoring stations. The upstream surface water monitoring station (SW-5) reported a 1,4-dioxane concentration of 14 ug/l. Both downstream surface water monitoring stations on the Southern Intermittent Stream (SW-3 and SW-4) reported detectable concentrations of 1,4-dioxane of 9.7 ug/l and 1,700 ug/l, respectively. No other Site VOCs were reported above the laboratory reporting limit in surface water monitoring stations SW-3 and SW- 5. In addition to the reported concentration of 1,4-dioxane in the sample collected from surface water monitoring station SW-4, several Site VOCs were also reported in this sample. A summary of the analytical report for the Southern Intermittent Stream samples is provided in Table 3. Northern Intermittent Stream The Northern Intermittent Stream surface water sampling stations include:  SW-1 Surface Water Station – Upstream of the Landfill, and  SW-2 Surface Water Station – Downstream of the Landfill. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 16 The flow path of the Northern Intermittent Stream was re-routed in 2011 and no longer passes through a pipe beneath the Landfill. Due to a limited watershed area, surface water monitoring station SW-1 is typically dry except during periods of heavy rainfall. Surface water sample SW-1 was dry during the October 2017 monitoring event and no sample was collected. The surface water station SW-2 was formally located at the end of the pipe beneath the Landfill which has now been converted into a collection sump for leachate accumulation. Surface water station SW-2 has now been relocated to the outfall of the re-routed Northern Intermittent Stream as shown on Figure 2. A surface water sample was collected at the SW-2 location during the October 2017 monitoring event. No Site VOCs or 1,4-dioxane was reported in this sample above the laboratory reporting limits. 6.3 Surface Water Re-Sampling Activities Based on the October 2017 1,4-dioxane laboratory analytical results of the surface water samples collected from the Randleman Reservoir and the Southern Intermittent Stream, additional sampling activities were conducted to verify the 1,4-dioxane laboratory analytical results. A sample was also collected for Site VOCs from the SW-4 surface water monitoring station to verify the reported October 2017 results. As described below, the limited re-sampling event was conducted on November 29, 2017 and the laboratory analytical report was received on December 11, 2017. Randleman Lake The Randleman Lake sampling stations include SW-6, SW-7, SWDRP-2, and SWDRP-11. On November 29, 2017, surface water samples were collected from all four of the surface water stations on the lake at shallow (1’ below surface) and deep (1’ above bottom) locations. A description of the laboratory analytical results is provided below: Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 17  SW-6 Surface Water Station – This is the upstream and background sample location on the Randleman Lake. The initial surface water monitoring results from the October 2017 monitoring event reported shallow/deep 1,4-dioxane concentrations of 13/14 ug/l. The November 29, 2017 re-sampling did not report any concentration of 1,4-dixane above the laboratory reporting limit of 2.0 ug/l in the shallow or deep sample.  SW-DRP-2 Surface Water Station – This surface water station is located on the east-west segment of the lake adjacent to Lift Station 1 and the primary extraction well PW-DR1. The laboratory results of the October 2017 shallow/deep samples reported 1,4-dioxane concentrations of 19/21 ug/l. The November 29, 2017 re-sampling event reported a shallow/deep 1,4-dioxane concentration of 3.4 ug/l in both shallow and deep samples at the SW-DRP-2 location.  SW-7 Surface Water Station – This surface water sample location is to the southeast of the Site where Interstate 85 crosses the Randleman Lake. The laboratory results of the October 2017 shallow/deep samples reported 1,4- dioxane concentrations of 26/20 ug/l. The November 29, 2017 re- sampling event reported a shallow/deep 1,4-dioxane concentration of 8.9/9.1 ug/l at the SW-7 location.  SW-DRP-11 Surface Water Station – This surface water station is located approximately one mile downstream of the Site at the confluence of the Randleman Lake and Richland Creek.

The November 29, 2017 re- sampling event reported a 1,4-dioxane concentration of 20 ug/l in both shallow and deep samples at the SW-DRP-2 location. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 18 Southern Intermittent Stream The Southern Intermittent Stream sampling stations include SW-3, SW-4, and SW-5. All three of the surface water stations on the Southern Intermittent Stream were re-sampled on November 29, 2017. A description of the laboratory results is provided below:  SW-5 Surface Water Station – This surface water station is located upstream of the former Seaboard Facility and downstream of the City’s Material Recovery Facility. The laboratory results of the October 2017 surface water sample reported a 1,4-dioxane concentration of 14 ug/l. The November 29, 2017 re-sampling event reported a 1,4-dioxane concentration of 8.6 ug/l at the SW-5 location. Note that while SW-5 is the upstream sample location on the Southern Intermittent Stream, it is also topographically downgradient of the Soil Residue Mound.  SW-3 Surface Water Station – This surface water station is located downstream of the former Seaboard Facility and upstream of the Landfill. The laboratory results of the October 2017 surface water sample reported a 1,4-dioxane concentration of 9.7 ug/l. The November 29, 2017 re- sampling event reported a 1,4-dioxane concentration of 15 ug/l at the SW- 3 location.  SW-4 Surface Water Station – This surface water station is located downstream of both the former Seaboard Facility and the Landfill. The laboratory results of the October 2017 surface water sample reported a 1,4-dioxane concentration of 1,700 ug/l along with numerous Site VOCs. The November 29, 2017 re-sampling event reported a 1,4-dioxane concentration of 1,500 ug/l and confirmed the presence of the Site VOCs at the SW-4 surface water sampling location. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 19 Northern Intermittent Stream As noted above, the flow path of the Northern Intermittent Stream was re-routed in 2011 and no longer passes through a pipe beneath the Landfill. Due to a limited watershed area, surface water monitoring station SW-1 and SW-2 are typically dry except during periods of heavy rainfall.  SW-1 Surface Water Station – This surface water station is located upstream of the Landfill. Surface water sample SW-1 was dry during the October 2017 monitoring event and no sample was collected. This surface water station was also dry during the November 29, 2017 re-sampling event and no sample was collected.  SW-2 Surface Water Station – This surface water station is located at the outfall of the Northern Intermittent Stream and downstream of the Landfill. A surface water sample was collected at the SW-2 location during the October 2017 monitoring event which did not report 1,4- dioxane or any Site VOCs above the laboratory reporting limits. This surface water station was dry during the November 29, 2017 re-sampling event and no sample was collected. A summary of the laboratory analytical results for both the October and November 2017 monitoring events is provided on Table 3. A copy of the laboratory analytical reports are provided with Appendix A. 6.4 Quality Control Samples Three trip blanks were submitted and analyzed for quality assurance purposes. No VOCs were detected at a concentration equaling or exceeding its laboratory quantitation limit in any of the trip blanks. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 20 7.0 Conclusions The major findings of the annual groundwater and surface water monitoring activities for October 10 – 17, 2017, including the November 29, 2017 re-sampling event, at the Site include the following:  Based on the October 2017 monitoring data, groundwater levels at monitoring wells located adjacent to the Randleman Lake have risen approximately 10 to 12 feet compared to pre-lake water level conditions. Inland from the lake, the 2017 groundwater levels at wells located on the western portion of the Site are approximately 4 feet higher compared to pre-lake water level conditions.  The overall groundwater flow pattern (Figure 2) at the Site continues to be toward Randleman Lake on both sides of the Lake basin. Pumping of the extraction well PW-DR1 over the past year indicates a significant capture zone for monitoring wells along the northern section of the Landfill adjacent to the Randleman Lake. The observed capture zone also extends to the bedrock wells on the north side of the Randleman Lake. The capture zone can be maintained by pumping extraction well PW-DR1 at a rate of approximately 15 gallons per minute.  During the October 2017 monitoring event, concentrations of 1,4-dioxane above the laboratory reporting limit were reported in the surface water monitoring stations on the Southern Intermittent Stream and the Randleman Lake. As summarized on Table 3, the reported concentrations of 1,4-dioxane in Southern Intermittent Stream and Randleman Lake surface water samples exceeded the NC 2B Surface Water Standard for 1,4-dioxane of 3.1 ug/l. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 21  To further evaluate the reported concentrations of 1,4-dioxane in the surface water at the site, additional surface water samples were collected. All surface water stations were re-sampled on November 29, 2017 and analyzed for 1,4- dioxane to provide for further evaluation of the surface water quality at the Site. The results of the November 29, 2017 surface water re-sampling event confirmed the presence of 1,4-dioxane above the NC 2B Surface Water Standard at several locations. The results of the November 29, 2017 surface water re-sampling event indicates the surface water samples collected from the Southern Intermittent Stream and from the Randleman Lake contain concentrations of 1,4-dioxane which exceed the existing 2B NC Surface Water Standards. A study is currently underway to evaluate the cause for the apparent change in the contaminant concentrations in the Southern Intermittent Stream surface water sample location and investigate technically feasible options to reduce the contaminant concentrations. The results of this study and recommendations to address the identified issues will be provided to NC DEQ upon completion.  During the October 2017 monitoring event, the Northern Intermittent Stream downgradient surface water monitoring station (SW-2) sample did not contain any Site VOCs or 1,4-dioxane concentrations above the laboratory reporting limits. The SW-1 surface water monitoring station was dry at the time of the October 2017 monitoring event. During the re-sampling event conducted on November 29, 2017, both SW-1 and SW-2 surface water monitoring stations were dry and no samples were collected.  Based on the October 2017 monitoring results and historical data, the main VOC plume extends from the former Seaboard Facility and Landfill soil residue mound through the Southern Intermittent Stream valley northeastward to Randleman Lake. The VOCs and 1,4-dioxane detected on the north side of Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report October 2017 Page 22 the lake across from the Site in monitoring wells PW-14D, PW-15D, and PW- 16D represents the northern extent of the VOC plume. Based on historical groundwater analytical results, the northern extent of Site VOCs in the groundwater north of Randleman Lake is likely located in the PTRWA buffer area between monitoring wells PW-14D/15D/16D and PW-18. Overall, the October 2017 groundwater monitoring results are generally consistent with historical monitoring data. The geometry and migration of VOC-affected groundwater at the Site have not been substantially altered by the filling of Randleman Lake to normal pool. Pumping of extraction well PW-DR1 at a rate of 15-20 gallons per minute has demonstrated a significant capture zone created by the drawdown on both sides of Randleman Lake.           FIGURES           TABLES TABLE 1 GROUND WATER ELEVATION DATA SEABOARD CHEMICAL/RIVERDALE DRIVE LANDFILL SITE JAMESTOWN, NORTH CAROLINA Page 1 of 23 Depth (feet BGL) Elevation (feet MSL) MW-1 57.71 47.71-57.71 743.98-733.98 789.40 791.69 11/14/2000 27.28 764.41 9/4/2001 27.99 763.70 9/17/2002 29.55 762.14 9/11/2003 23.86 767.83 8/16/2004 25.70 765.99 12/19/2005 25.55 766.14 8/21/2006 25.97 765.72 9/24/2007 26.33 765.36 2/23/2009 25.35 766.14 3/29/2010 24.89 765.72 11/1/2011 27.69 764.00 11/16/2012 27.23 764.46 12/9/2013 28.36 763.33 12/8/2014 28.54 763.15 New Survey 788.85 790.46 10/26/2015 27.99 763.47 11/14/2016 27.50 762.96 10/11/2017 28.43 762.03 MW-2A 19 4-19 709.9-694.9 711.80 713.90 11/14/2000 13.46 700.44 9/4/2001 17.43 696.47 9/17/2002 10.25 703.65 9/11/2003 10.60 703.30 8/16/2004 7.83 706.07 8/21/2006 13.04 700.86 9/24/2007 14.17 699.73 2/23/2009 10.67 703.23 3/29/2010 6.11 707.79 11/1/2011 8.18 705.72 11/16/2012 12.90 701.00 MW-2B 30 30 681.0 711.00 712.57 11/14/2000 12.78 699.79 9/4/2001 13.01 699.56 9/17/2002 10.61 701.96 9/11/2003 10.62 701.95 8/16/2004 7.75 704.82 8/21/2006 12.25 700.32 9/24/2007 14.64 697.93 2/23/2009 10.35 702.22 3/29/2010 6.05 706.52 11/1/2011 9.16 703.41 1/16/2012 12.21 700.36 MW-2C 48 28-48 685.56-665.56 711.40 713.56 11/14/2000 16.12 697.44 9/4/2001 14.02 699.54 9/17/2002 18.41 695.15 9/11/2003 12.78 700.78 8/16/2004 14.80 698.76 12/19/2005 NM NM 8/21/2006 17.53 696.03 9/24/2007 16.86 696.70 2/23/2009 14.25 699.31 3/29/2010 10.97 702.59 11/1/2011 14.55 699.01 11/16/2012 15.82 697.74 DEPTH TO WATER (feet BTOC) GROUND WATER ELEVATION (feet MSL) TOP OF CASING ELEVATION (feet MSL) GROUND ELEVATION (feet MSL) SCREENED INTERVAL TOTAL DEPTH (feet BGL) MONITOR WELL I.D.

The analyte was detected in the associated method blank. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content.

The analyte was detected in the associated method blank. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content.
