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 facility, 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 November 2018 Page 1 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 November 2018 Page 2 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 DEQ 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 N20°E 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 November 2018 Page 3 Southern Intermittent Stream Fault — N80°E oriented fracture zone/fault that parallels the Southern Intermittent Stream. Based on an on -site outcrop measurement and fracture orientation data from the PW-31) core, the fracture zone is believed to dip 43' to the south; Seaboard Dike — N20°E 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 — N200E 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-51) Fault has an inferred connection with the Southern Intermittent Stream Fault beneath the Landfill; Regional Fault/Dike — major regional fault/mafic dike that extends N20°E 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 50' 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 November 2018 Page 4 (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 November 2018 Page 5 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 2018 annual groundwater and surface water monitoring activities were conducted at the Site during the period of October 31 through November 7, 2018. As described in Section 6 of this report, re -sampling activities were conducted on January 10, 2019 for one monitoring well (PW- 18) and two surface water locations (SW-1 and SW-2) to confirm the initial laboratory analysis. 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). 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 November 2018 Page 6 MW-1 (background) MW-3C MW-6 MW-10 MW-1 2A MW-12B MW-12D MW-15A OW-DR2 OW-LFS2 PW-31) PW-4I PW-5D PW-6I PW-61) PW-10I PW-1 OD PW-12I PW-13I PW-14D PW-15D PW-16D PW-18 PW-SF1 W-4A Monitoring well construction information and groundwater elevations for the 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 Intermittent Stream, Southern Intermittent Stream, and on the Randleman Lake. The nine surface water stations sampled for the water quality monitoring program include: SW-1 SW-3 SW-5 SW-7 SW-DRP-11 SW-2 SW-4 SW-6 SW-DRP-2 * The surface water samples collected from the Randleman Lake are collected at two discrete depths, 1' below the surface and l' above the bottom of the Lake. Seaboard Chemical/Riverdale Drive Landfill November 2018 Water Quality Monitoring Report Page 7 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 2018 annual groundwater and surface water monitoring activities were conducted at the Site during the period of October 31 through November 7, 2018. 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. After purging of the monitoring wells, 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 November 2018 Page 8 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 November 2018 Page 9 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 November 2018 Page 10 5.0 Hydrogeological Conditions The depth to groundwater was measured in the 25 compliance monitoring wells during the October/November 2018 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 across the Site is northeastward toward Randleman Lake. The vertical hydraulic gradient in the shallow bedrock aquifer, as measured between monitoring wells MW-3C and OW-DR2 during the November 2018 monitoring event, was 0.014 feet/feet upward. 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 gallons per minute 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/November 2018 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 November 2018 Page 11 6.0 Laboratory Analytical Results Final analytical results for the samples collected during the period of October 31 through November 7, 2018 were received from the laboratory on November 21, 2018. 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/November 2018 monitoring event are shown in a series of figures. Groundwater quality maps representing the bedrock aquifer 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). The historical groundwater analytical results for specific VOCs, including the 2018 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 during sample collection 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 impacted 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. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report November 2018 Page 12 VOCs were detected in a limited area across Randleman Lake to the northeast of the Site. Concentrations of VOCs and 1,4-dioxane at levels above the North Carolina 2L Groundwater Quality Standards were detected at off -site bedrock monitoring wells PW- 141), PW-151), and PW-161), 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). A review of the October/November 2018 analytical data noted the presence of chlorinated VOCs in groundwater monitoring well PW-18 which were inconsistent with past monitoring results. The chlorinated compounds cis-1,2-dichloroethene and trichloroethene were reported in well PW-18 at concentrations above the laboratory quantitation limits. This well was re -sampled on January 10, 2019 to verify the initial analytical results. The results of the re -sampling indicated concentrations of chlorinated VOCs were below the laboratory quantitation limits and consistent with historic water quality results. The cause for the initial reporting of low concentrations of chlorinated VOCs in monitoring well PW-18 is likely due to sampling or laboratory analytical interferences. The laboratory analytical results of the initial sample collected from PW- 18 and the re -sampling event are provided on Table 2. Overall, the October/November 2018 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 Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report November 2018 Page 13 surface water results for VOCs and 1,4-dioxane are summarized in Table 3 and the ENCO laboratory report is provided in Appendix A. 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 laboratory analytical data indicated no VOCs or 1,4-dioxane concentrations above the laboratory reporting limits in any of the Randleman Lake surface water samples. The locations of the surface water monitoring stations are shown on Figure 2 and a summary of the Randleman Lake surface water analytical results are provided in Table 3. Based on field observations during the October/November 2018 monitoring activities, the Randleman Lake was approximately two (2) feet above normal pool elevation of 682 feet msl. 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. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report November 2018 Page 14 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 23 ug/l. Both of the downstream surface water monitoring stations on the Southern Intermittent Stream (SW-3 and SW-4) reported detectable 1,4-dioxane concentrations of 13 ug/1 and 48 ug/l, respectively. No other Site VOCs were reported above the laboratory reporting limit in the sample collected from surface water monitoring station SW-5. In addition to the reported concentration of 1,4-dioxane in the samples collected from surface water monitoring stations SW-3 and SW-4, several Site VOCs were also reported in these samples. A summary of the analytical data 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. 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, these two surface water monitoring stations are typically dry except during periods of heavy rainfall. Due to the abnormal amount of rainfall at the Site during the fall of 2018, surface water flow was observed at both SW-1 and SW-2 locations. Surface water samples were collected at the SW-1 and SW-2 locations during the October/November 2018 monitoring event. Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report November 2018 Page 15 No Site VOCs were reported in either of the Northern Intermittent Stream sampling locations. The compound 1,4-dioxane was reported in both SW-1 and SW-2 locations at concentrations of 12 ug/1 and 22 ug/l, respectively. Based on the initial 1,4-dioxane laboratory analytical results for the surface water samples collected from SW-1 and SW-2, re -sampling activities were conducted to verify the 1,4-dioxane laboratory analytical results. The results of the January 10, 2019 re -sampling event reported a 1,4-dioxane concentration of below laboratory reporting limits at the SW-1 location and 15 ug/l at the SW-2 location. A summary of the laboratory analytical results for both the October/November 2018 monitoring event and January 2019 re -sampling event is provided on Table 3. A copy of the laboratory analytical reports are provided with Appendix A. 6.3 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 November 2018 Page 16 7.0 Conclusions The major findings of the annual groundwater and surface water monitoring activities for October/November 2018, including the January 10, 2019 re -sampling event, at the Site include the following: • Based on the October/November 2018 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 2018 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. • The surface water samples collected from the Randleman Lake during the October/November 2018 monitoring event did not report detectable concentrations of 1,4-dioxane or VOCs above the laboratory reporting limit. • During the October/November 2018 monitoring event, concentrations of 1,4- dioxane above the laboratory reporting limit were reported in the surface water monitoring stations on the Northern and Southern Intermittent Streams. As summarized on Table 3, the reported concentrations of 1,4-dioxane in Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report November 2018 Page 17 Northern and Southern Intermittent Stream surface water samples exceeded the NC Protective Value for 1,4-dioxane of 3.1 ug/l. • Based on the October/November 2018 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 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 regulated buffer area between monitoring wells PW-14D/15D/16D and PW-18. Overall, the October/November 2018 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.

I Page 44 Of 47 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J 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. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL 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. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. QM-10 LCS/LCSD were analyzed in place of MS/MSD. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

J 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. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL 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. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. QI-04 The internal standard(s) for this sample were outside the acceptance limits due to sample matrix interference which was confirmed by reanalysis. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-10 LCS/LCSD were analyzed in place of MS/MSD.

I Page 43 Of 46 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J 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. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL 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. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-10 LCS/LCSD were analyzed in place of MS/MSD.

U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL 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. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. QM-10 LCS/LCSD were analyzed in place of MS/MSD.
