L U22 -Aquifer 6114 Fourwood Drive Matthews, NC 28104 Attention: Mr. Jim McClain Reference: Comprehensive Site Assessment Carolina Concrete, NCDENR Incident No. 87717 11509 Reames Rd, Charlotte, Mecklenburg Co., NC S&ME Project No. 1354-05-687C Dear Mr. McClain: S&ME, Inc. (S&ME) submits the attached Comprehensive Site Assessment (CSA) to Carolina Concrete, Inc., in general accordance with S&ME's Proposal No. 1354-17027-06, dated September 11, 2006. Based on the results presented in the CSA, the petroleum release from the former 10,000-gallon above ground diesel storage tank (AST) has impacted the groundwater quality at a level slightly above the 15A NCAC 2L .0202 groundwater quality standards, and the impact appears to be localized around the area of the former AST. The concentration of C9-C22 Aromatics in a source ` area monitor well installed at the location of the former AST was 650 micrograms per liter (µg/L), compared to the groundwater quality standard of210 µg/L. No petroleum contaminants i were detected in three other shallow monitor wells located within 75 feet (upgradient, sidegradient and downgradient) of the source area monitor well. Groundwater flow from the area of the former AST is to the north. Several water supply wells supplying potable water to the users are located within 1,500 feet of the former AST, however, the nearest water supply well in the approximate downgradient direction is located approximately 970 feet to the northeast.

Senior Geolotist Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 EXECUTIVE SUMMARY S&ME, Inc. (S&ME) was retained by Carolina Concrete, Inc. to conduct a Comprehensive Site Assessment (CSA) at former Carolina Concrete facility located at 11509 Reames Rd, Charlotte, Mecklenburg County, North Carolina (Figure 1). The facility is currently operated by Ready Mixed Concrete. The CSA is associated with a petroleum release from a I0,000-gallon diesel above ground storage tank (AST) system that was removed in October 2005. This CSA does not include an evaluation of the vertical extent of impacted groundwater or aquifer testing, as approved by Ms. Amber Lindon with the North Carolina Department of Environment and Natural Resources (NCDENR) during a telephone call with Al Quarles and Paul Hattenhauer (Culp Elliott & Carpenter, P.L.L.C, legal counsel for Carolina Concrete, Inc.) on September 19, 2006. 1. SOURCE INFORMATION Diesel fi-om a I0,000-gallon aboveground storage tank (AST) was released to the environment. The source was likely a combination of surface spillage and leaks from the dispenser. The quantity of the release is unknown. 2. INITIAL ABATEMENT The AST and petroleum -impacted soil were removed during October and November 2005. The soil was disposed at the Allied Waste/CMS Landfill in. Concord, North Carolina. The excavation was approximately 30 feet wide by 40 feet long to a depth of approximately 18 feet below land surface, where groundwater was observed entering the base of the excavation. In an effort to reduce the contaminant levels in the groundwater at monitor MW-1, S&ME performed two Aggressive Vapor Fluid Recovery (AFVR) events using well MW-1, on June 13 and September 21, 2006, with 80 and 176 gallons of water removed, respectively. 3. RECEPTOR INFORMATION Water is supplied to nearby businesses and residences by municipal water and water supply wells. S&ME identified eight (8) active water supply wells within 1,500 feet of the former AST. One of these eight wells was capped but not abandoned. Two other properties were indicated by 110 Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 Mecklenburg County to have wells, however, the presence of these two wells was not confirmed by S&ME. The nearest well is approximately 280 feet south (upgradient) of the former AST on property owned by Carolina Concrete (different property than the subject site). The nearest downgradient water supply well is located approximately 970 feet to the northeast. Based on the USGS Topographic Map of the area, there is one surface water body within 1,500 feet of the former AST: an intermittent stream located approximately 550 to 600 feet to the north. The site is not located within a Wellhead Protection Area and there are no underground utilities in the area of the former AST. 4. SAMPLING/INVESTIGATION RESULTS During October 2005 and prior to AST/Soil removal, soil sampling around the AST area indicated Total Petroleum Hydrocarbons (TPH), Diesel Range Organics (DRO) and Gasoline Range Organics (GRO) in the soil with maximum concentrations of 3,100 milligrams per kilogram (mg/kg) of DRO and 5-7 mg/kg of GRO. Sidewall soil samples collected following soil removal indicated maximum TPH concentrations of 6.2 mg/kg for DRO and 1.3 mg/kg for GRO, both less than the NCDENR's cleanup levels of 40 mg/kg for DRO and 10 mg/kg for GRO. The July 25, 2006 groundwater sampling results of the source area well MW-1 indicated levels of C9- C22 Aromatics at a concentration of 650 micrograms per liter (µg/L) compared to the 15A NCAC 2L .0202 groundwater quality standard (2L Standard) of 210 µg/L. Groundwater sampling from three additional monitoring wells in October 2006 did not indicate the presence of any semi -volatile organics (EPA Method 625) or C9-C22 Aromatics (MADEP Method VPH/EPH), Wells MW-2, MW-3 and MW-4 are located approximately 45 feet, 65 feet and 75 feet from MW-1, respectively. Thus, the extent of impacted groundwater above the 2L Standards appears to be limited to the area of the former AST. The underlying bedrock is metamorphosed quartz diorite and tonalite. The upper soil consist of reddish brown sandy silt to silty sand to depths of 29 feet below land surface. The groundwater surface in the area of the former AST is approximately 14 feet below land surface (approximately 2 feet below land surface at monitor well MW-3). Groundwater flow is to the north from well MW-1 toward well MW-4, under a hydraulic gradient of approximately 0.01 ft/ft. Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 The soil cleanup levels are 40 mg/kg for TPH-DRO and 10 mg/kg for TPH-GRO. Soil sampling at the time of soil excavation did not indicate levels above the cleanup levels. The groundwater cleanup levels are the 2L Standards. Only one contaminant, C9-C22 Aromatics, detected in only one well (MW-1) exceeded the groundwater cleanup levels. 5. CONCLUSIONS AND RECOMMENDATIONS Sol] sampling results do not indicate the presence of petroleum -impacted soil above the cleanup levels. The extent of petroleum -impacted groundwater above the groundwater cleanup levels appears to be limited to the area of the former AST (downgradient monitor well MW-4 is approximately 75 feet from the source area well MW-1). Only one contaminant (C9-C22 Aromatics) in one well (MW- I ) was detected above the 21, Standards. Groundwater flow is to the north. The nearest downgradient water supply well is approximately 970 feet to the northeast. Based on the findings presented in this CSA, we recommend the following: • Abandon monitor wells MW-2, MW-3 and MW-4. • Quarterly monitoring of monitor well M W-1 until such time the concentration of C9-C22 Aromatics decreases to below the 2L Standard, followed by requesting a Notice of No Further Action from the NCDENR and the abandonment of monitor well MW-1. w Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 1.0 SITE HISTORY AND SOURCE CHARACTERIZATION 1.1 PROPERTY DESCRIPTION The property is located at 11509 Reames Rd, Charlotte, North Carolina and is approximately 6.9 acres. The property includes one 2-story block building, several storage silos, mixing equipment, sand and gravel storage areas and a stormwater pond. The property is owned by Carolina Concrete who acquired the property in March 1989, according to the Mecklenburg County POLARIS website. A 10,000-gallon, above groui:d diesel storage tank (AST) was located in the southeast portion of the property). See Site Photographs in Appendix 1. 1.2 SOURCE OF RELEASE A release of diesel from the former 10,000-gallon diesel AST system impacted the soil and groundwater. The quantity of diesel released is not known. The source was likely a combination of surface spillage and leaks from the dispenser. 1.3 PREVIOUS ACTIVITIES Previous assessment and remediation activities at the site include the following: 1. Phase I Environmental Site Assessment: S&ME performed a Phase I ESA for this site with the results submitted in a report dated November 16, 2005. The Phase I ESA indicated one recognize" ei7.viioni77e;7tai coi7diti,o77, the 10,000-gallon AST system. Sori sampling and remediation activities were also performed prior to November 16, 2005. 2. Soil Sampling and Remediation: In support of the above Phase 1 ESA, S&ME performed a Phase II ESA that included soil sampling around the AST system. On October 14, 2005, S&ME collected soil samples using a hand auger at four locations (14A-1 through HA-4) in the area of the AST and dispenser for laboratory analysis of Total Petroleum Hydrocarbons (TPH), Diesel Range Organics (DRO) and Gasoline Range Organics (GRO). The locations are provided in Appendix I (Figure 2 and Site Photographs from S&ME's January 9. 2006 Soil Remediation Report). The sample depths and TPH results are presented in Table 1. TPH-DRO levels ranged 470 to 3,100 milligrams per kilogram (mg/kg) and TPH-GRO levels ranged from less than 5 mg/kg to 57 mg/kg. The North Carolina Department of Environment and Natural Resources (NCDENR) cleanup levels are 40 mg/kg for TPH-DRO and 10 mg/kg for TPH-GRO. Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 On October 18, 2005, S&ME collected one soil sample (GP-1), via Geoprobe, east of the AST fi-om a depth of approximately 18 feet below ground surface (ft-bls) to evaluate the vertical extent of impacted soil. The sample location is provided in Appendix I (Figure 2). TPH-DRO was detected at a level of 27 mg/kg and TPH-GRO was detected at a level of 0.87 mg/kg. On October 27, 2005, following removal of the AST, concrete berm/pad and apparent petroleum - impacted soil by Carolina Concrete, S&ME collected one composite sample (CS-1) of the excavated, stockpiled soils for laboratory analysis (benzene, ethylbenzene, toluene and xylenes using EPA Method 8260). The purpose of this sampling was to obtain approval for soil disposal at the BFI Landfill in Concord, North Carolina. The analytical results indicated the presence of ethylbenzene (0.130 mg/kg), toluene (0.006 mg/kg) and xylenes (0.400 mg/kg). Excavation of apparent petroleum -impacted soil continued.through October 31, 2005, to a depth of approximately 18 feet below land surface where groundwater was observed to be seeping into the excavation. On October 31, 2005, S&ME collected four sidewall samples (SW-1 through SW-4).for laboratory analysis: The locations of the samples are provided in Appendix I (Figure 2). No bottom sample was collected since the groundwater was encountered due to the presence of groundwater at base of the excavation. Sample SW-1 was the only sample with TPH-DRO (1,700 mg/kg) and "TPH-GRO (12 mg/kg) at levels above .the cleanup levels. Due to these TPH levels, additional soil was excavated from that side of the pit. On November 9, 2005, a second sidewall sample (SW-1 A) was collected for laboratory analysis, and the results were below the cleanup levels. The results of the above soil sampling and remediation were reported in S&ME's January 19.. 2006 Soil Remediation Report. Copies ofthe laboratory reports are included in Appendix 11. 3. Groundwater Assessment: On February 8, 2006, McCall Brothers under contract with S&ME, installed one monitor well (MW-1) at the location of the former AST (Figure 2). The well was installed within a bore hole drilled using 8.25-inch outer diameter hollow -stem augers, and constructed of 2-inch diameter PVC screen (set from 14 to 29 feet below land surface) and riser pipe. The annulus was filled with sand (12 to 29 feet), bentonite (10 to 12 feet) and grout (to land surface). A Non -Residential Well Completion Record for well MW-I is included in Appendix I11. On February 9, 2006, the depth to groundwater below land surface was approximately 14.5 feet below land surface. 2 Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 On February 9, 2006, S&ME collected a groundwater sample from well MW-1 for laboratory analysis using EPA Methods 602/625 and MADEP Methods VPH/EPH. The results indicated the presence of benzene (1.9 µg/L), naphthalene (64 µg/L) and C9-C22 Aromatics (760 µg/L) at levels above the 2L Standards of 1, 21 and 210 µg/L, respectively. The sampling results from well MW-1 are summarized in Table 2 and a copy of the laboratory report is included in Appendix 11. The above results were included in S&ME's February 20, 2006, Groundwater Sampling Report. 1.4 GEOGRAPHICAL SETTING AND LAND USE The subject site is approximately 6.9 acres located approximately 1300 feet northwest of the intersection of Reames Road and NC Highway 115 (Old Statgsville Road) in Charlotte, North Carolina. The former AST was located in the southeast corner of the property approximately 490 feet north of Reames Road. The site is mostly developed with a small wooded area to the north. One two -store building includes the office, restrooms, control equipment and two maintenance bays. Concrete mixing equipment and material storage areas are located west and northwest of the building. A stormwater retention pond is located north of the building. The surrounding land use is developed for residential or commercial use. S&ME reviewed the 1993 Derita Quadrangle of the United States Geological Survey (USGS) 7.5- minute series topoUaraphic Inap from 1 erraserver to examine the topography and drainage of the subject property and vicinity. The surface elevation of the subject property varies from approximately 840 feet above mean sea level (MSL) along the access road, 820 feet above MSL in the former AST area to approximately 795 in the northwestern portion of the property along a drainage feature that flows to the north from the southeastern portion of the property to the northwestern portion of the property. Based on a review of this map, it appears that the groundwater in the vicinity of the former AST would flow to the north to northeast toward a tributary of Dixon Branch (part of the Catawba River Basin). Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 1.5 CSA SCOPE OF WORK S&ME developed a CSA Workplan in general accordance with NCDENR guidance published in the Groundwater Section Guidelines for the Investigation and Renaediation of Soil and Groundwater, July 2000 (i.e. the Guidelines) and a September 19, 2006 conversation with Ms. Amber Lindon of the NCDENR. The assessment was conducted pursuant to Title 15A of the North Carolina Administrative Code (NCAC), Subchapter 2L, Section .0106 (c) as requested in NCDENR's Notice of Violation dated April 4, 2006. S&ME performed the following activities: • Reviewed previous' investigation reports; • Reviewed available geologic and hydrogeologic publications to describe regional geologic and hydrogeologic units; • Conducted a water supply well survey within 1,500 feet of the site; • Conducted a survey of underground and overhead utilities at the site; • Installed three additional groundwater quality monitoring wells, collected groundwater samples, and analyzed the samples for petroleum constituents; • Measured the elevation of each monitoring well, measured groundwater levels, and estimated the direction of groundwater flow and hydraulic gradient across the site; • Prepared this CSA Report to summarize the results of the assessment. 2.0 LOCAL RECEPTOR SURVEY Information pertaining to potential receptors identified within the 1,500 foot search radius, of the subject site is summarized in the following sections. 2.1 WATER SUPPLY WELLS The receptor survey was conducted by S&ME on October 20, 2006. The survey consisted of a site visit, a review of the 2005 aerial obtained from the Mecklenburg County POLARIS website, and an area reconnaissance completed in a vehicle that included public roadways within 1,500 feet of the subject site. The locations of water supply wells identified are illustrated on Figure 3, with property and available well information provided in Table 4. 4 Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 S&ME identified eight (8) active potable water supply wells (#1 through 47 and 49) within 1,500 feet of the former AST. One of these eight wells (#9) was capped (not in use) but not abandoned. Two other properties were indicated by Mecklenburg County to have wells (#8 and #10), however, the presence of these two wells was not verified by S&ME. The nearest well (# ]) is approximately 280 feet south (upgradient) of the former AST on property owned by Carolina Concrete (different property than the subject site). The next nearest wells (44 and #5) are located to the east (sidegradient) approximately 500 and 540 feet from the former AST. The nearest approximate downgradient water supply well is well #8, located approximately 970 feet to the northeast. Based on topography, groundwater flow from the former AST area is likely to turn to the northwest (away from water supply well 48) prior to leaving the property. Note that the three monitor wells located within 75 feet of the former AST to the west-northwest, north and north-northeast did not contain detectable levels of petroleum contaminants, suggesting that the potential for impact to the off -site water supply wells fi-om the on -site diesel release is low. No subsurface utilities were identified within the former AST area. 2.3 ADJACENT PROPERTY OWNERS AND OCCUPANTS Information on property owners was obtained from the Mecklenburg County POLARIS Website. The parcel identification numbers, owner's name and address are summarized on Table 5. Petroleum impacted groundwater is not anticipated to migrate off -site to the adjacent properties. 2.4 PUBLIC WATER SUPPLIES Based on S&ME's survey, there are no public water supply wells used for potable drinking water located within the search radius. Municipal water is supplied to the property and nearby businesses and residences by the Charlotte -Mecklenburg Utilities Department, which obtains its water from Lake Norman (-7.5 miles northwest of the site) and Mountain Island Lake (-5.25 miles west of the site). 2.5 SURFACE WATER A drainage feature crosses the property from the southeast corner and intersects an intermittent stream in the northwestern portion of the property approximately 550 feet northwest of the former AST. Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 This intermittent stream flows generally to the west to southwest, where it enters Long Creek and eventually the Catawba River over 12 miles fi-om the site. 2.6 WELLHEAD PROTECTION AREAS The site is not located within a Wellhead Protection Area. 2.7 DEEP AQUIFERS OF THE COASTAL PLAIN The site is not located in the Coastal Plain, but rather the Charlotte Belt of the Piedmont Physiographic Province. 2.8 LAND USE The site is mostly developed with a building, concrete mixing -equipment, material supply areas and a storm water retention basin. Part of the property to the east and north is wooded. Adjacent properties are either wooded or contain commercial businesses. Properties further to the south, west and north include commercial businesses and properties further to the east include residences. 3.0 GEOLOGIC FRAMEWORK 3.1 REGIONAL AND SITE GEOLOGY According to the 1988 Geologic Map of the Charlotte I ° X 2° Quadrangle, North Carolina and South Carolina, the subject property is located within the Charlotte Belt of the Piedmont Physiographic Province. In general, the bedrock in the region consists of igneous and metamorphic rock. The bedrock at the site is reported to consist of metamorphosed quartz diorite and tonalite, gray, usually medium- to coarse grained. generally foliated rock composed dominantly of plagioclase, quartz, biotite, hornblende, and epidote. The soils overlying the bedrock generally consist of granular material weathered in -place fi-om the previously existing bedrock, grading downward from a clay -rich soil (residuum) without structure from the original rock, to saprolite and partially weathered rock with structure fi-om the original rock. Generally, grain size and the quantity of rock fi-agments increase with depth as the unweathered rock Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 is approached. The depth to rock can vary greatly to near land surface to over 100 feet below land surface, but is generally encountered between 30 and 60 feet below land surface. At this site and well locations MW-1, MW-2 and MW-4, the lithology generally consists of red clayey to sandy silts to approximately I 1 to 13 feet below land surface, underlain by brown silty sand (saprolite) to the termination depths (25 to 29 feet below land surface). At MW-3, organic rich top soil was observed in the upper 6 inches followed by approximately l foot of red clayey sandy silt then brown silty sand to 20 feet below land surface. 3.2 REGIONAL AND SITE HYDROGEOLOGY The site is located in the Piedmont Physiographic Province. The groundwater surface generally occurs in the soils (Surficial Aquifer) overlying the bedrock (Bedrock Aquifer) and is typically within 25 feet of land surface. Generally, the Surficial Aquifer and Bedrock Aquifer are connected, with groundwater from the Surficial Aquifer migrating downward into the Bedrock Aquifer, or to a local discharge zone, i.e., local streams. The groundwater is recharged by precipitation, and generally flows from topographic highs to topographic lows, with the groundwater surface often a reflection of the surface topography. The groundwater surface at the site is within the saprolite overlying the partially weathered rock. Bedrock was not encountered to depths of 29 feet below land surface. 4.0 ASSESSMENT ACTIVITIES The CSA assessment was conducted pursuant to Title 15A of the North Carolina Administrative Code (NCAC), Subchapter 2L, Section .0106 in general accordance with the procedures outlined in the Guidelines, with modifications based on a September 19, 2006 telephone call with Ms. Amber Lindon of the NCDENR, Mr. Al Quarles of S&ME and Mr. Paul Hattenhauer of Culp Elliott & Carpenter, P.L.L.C. Activities not performed in this CSA include I ) installation and sampling of a deep monitor well to evaluate vertical extent of impacted groundwater, and 2) aquifer testing. Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 The equipment used to advance borings and collect samples was decontaminated before and after use to minimize the potential for cross -contamination. Sample identifications, depth, and analytical methods are summarized in Tables 1 and 2. 4.1 SOIL SAMPLING AND ANALYSIS S&ME performed three soil borings using hollow -stem auger drilling methods for the purpose of installing monitor wells. Soil samples were collected from the hand auger borings in two -foot intervals. Soil cuttings were observed for lithologic characterization and for the apparent presence of petroleum. No apparent petroleum was observed in the soil cuttings at well locations MW-2, MW-3 and MW-4. The boring/well locations are presented in Figure 2. The lithology at each location is presented on the Non -Residential Well Construction Records in Appendix Ill. The results of previous soil sampling reported in S&ME's Phase I ESA Report and Soil Remediation Report, are summarized in Table 1. The locations of the samples are presented in Appendix 1 (Figure 2 and Site Photographs). Laboratory reports for these samples are included in Appendix 11. The results of soil sampling and analysis performed following the removal of the petroleum -impacted soil to the groundwater surface During October and November 2005, did not indicate the presence of TPH above the cleanup levels in the four side.walls of the excavation. Groundwater was encountered at the base of the excavation, thus, no bottom sample was collected. 4.2 WELL INSTALLATION On October 11 and 12, 2006, S&ME installed three additional shallow wells (MW-2, MW-3 and MW-4) at the locations indicated on Figure 2. The locations were selected to be in the upgradient direction and still within the Carolina Concrete property (MW-2) and downgradient direction (MW-3 and MW-4) based on surface topography. Non -Residential Well Construction Records are included in Appendix III. The wells were installed within bore holes drilled using 8.25-inch outer diameter hollow -stem augers, and constructed of 2-inch diameter PVC screen (set from 10 to 25 feet below land surface for wells MW-2 and MW-4 and from 5 to 20 feet below land surface for well MW-3) and riser pipe. The annulus for each boring/well was filled with #2 sand from the base of the Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28 2006 borehole to 1 to 2 feet above the top of screen, two feet of bentonite above the sand pack and grout to land surface. 4.3 GROUNDWATER SAMPLING AND ANALYSIS Monitor well MW-1 (installed at the location of the former AST) was sampled on February 6, June 16 and July 25, 2006, prior to the CSA activities. The June 16 and July 25, 2006 sampling events were performed following AFVR events performed on June 13 and September 21, 2006, with 80 and 176 gallons of water removed, respectively. The groundwater sampling results are summarized in Table 2 and copies of the laboratory reports are included in Appendix 11, Note that the concentrations of benzene and naphthalene decreased to levels below the 2L Standards. The concentrations of C9-C22 Aromatics also decreased, however, the concentrations were still above the 2L Standards. The three new wells (MW-2, MW-3 and MW-4) were sampled on October 13 and 20, 2006, for Semi -Volatile Organics using EPA Method 8270 and C9-C22 Aromatics using MADEP Methods VPH/EPH. No contaminants were detected above laboratory method detection limits. The sampling results are summarized in Table 2 and copies of the laboratory reports are included in Appendix 11. Based on the most recent groundwater sampling results, only one contaminant (C9-C22 Aromatics) in one well (MW-1) was detected at a concentration above the 2L Standards. The horizontal extent of petroleum impacted groundwater appears to be localized around the former AST area (Figure 4). 5.0 GROUNDWATER LEVELS AND FLOW On October 23, 2006, the depth to groundwater ranged from approximately 13.8 feet (at MW-1) to 17 feet (at M WA) below land surface in the area of the former AST, to approximately 2 feet below land surface within the drainage feature located east to northeast of the former AST (Table 3). The ground surface elevation at the fonner AST (MW-1) is approximately 12 feet higher than that at well MW-3. Groundwater measurements on October 23, 2006 (Table 3) indicate groundwater flow to be to the north, from MW-1 toward MW-4 (Figure 5). The hydraulic gradient is approximately 0.01 ft/ft. Assuming an effective porosity of 0.15 and a hydraulic conductivity value of 1x10-5 cm/sec (typical for sandy silt and silty sand), the groundwater flow rate is estimated to be 10 feet per year. Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 6.0 CONCLUSIONS 6.1 RELEASE SCENARIO Based on the results of the Phase I ESA, petroleum was released from the 10,000-gallon diesel AST. The source of the release was likely a combination of surface spillage and leaks from the dispenser, and possibly from the underground piping from the AST to the dispenser. The volume of the release is unknown. 6.2 EXTENT OF IMPACTED SOIL The extent of impacted soil appears to have been limited to an area approximately 30 feet wide by 40 feet long, to a depth of approximately 18 feet below land surface. Soil sampling collected from the sidewalls of the soil excavation during October and November 2005 did not indicate the presence of TPH above the NCDENR's soil cleanup levels. 6.3 EXTENT OF DISSOLVED PETROLEUM HYDROCARBONS The most recent sampling of the four monitor wells indicated only one petroleum contaminant in only one monitor well at a level above the 2L Standards. On July 25, 2005, the concentration of C9-C22 Aromatics in monitor well MW-1 was 650 µg/L, compared to the 2L Standard of 210 µg/L. No contaminants were detected above laboratory's practical quantitation limits in the other three wells vv-�, ivJd✓-) anu 1`vi ✓v-4), locatedwithin i5 feet of>vlW-1. Based on the approval by Ms. Amber Lindon of the NCDENR, a vertical extent monitor well was not installed, thus the vertical extent of impacted groundwater was not evaluated. 6.4 POTENTIAL RECEPTORS Eight (8) confirmed active water supply wells and two (2) reported water supply wells are located within 1,500 feet of the former AST. The nearest downgradient water supply well is approximately 970 feet to the northeast. The nearest surface water body is located approximately 550 feet northwest of the former UST. Note that monitor wells (MW-2, MW-3 and MW-4) located within 75 feet of the former AST to the west-northwest, north and north-northeast did not contain detectable levels of petroleum contaminants, suggesting that the potential for impact to the off -site water supply wells from the on -site diesel release is low. lul Comprehensive Site Assessment S&ME Project No. 1354-05-687C Carolina Concrete, Charlotte, NC November 28, 2006 7.0 RECOMMENDATIONS Based on the soil and groundwater sampling results at this site, S&ME recommends the following corrective actions: 1. Abandon monitor wells MW-2, MW-3 and MW-4. 2. Monitor the water quality (C9-C22 Aromatics) in MW-1 on a quarterly basis until such time the results are below the 2L Standards. 3. Request a Notice of No Further Action from the NCDENR. 4. Abandon monitor well MW-1.
