Currently, a used car lot and a gym operate at the site. The site is surrounded predominately by residential properties with Crestwood Cemetery to the east, across Highway 21. Four 4,000-gallon gasoline tanks were closed and removed from the site in October 1992. During the closure activities, free product was observed flowing to a test pit that was excavated to a depth of 19 feet below land surface. Petroleum hydrocarbons were detected in the soil samples collected from the tank basin and dispenser areas. The closure was concluded by soil excavation and remediation of approximately 1,029 cubic yards of soil. Between 1993 and 1994, eight monitoring wells (MW-1 through MW-8) and two recovery wells (RW-5 and RW-6) were installed at the site. MW-1 is presumed destroyed and RW-6 is presumed to be paved over based on a December 2008 Terraine, Inc. Assessment Report. ATEC conducted an eight-hour aggressive fluid vapor recovery event in July 1996 and a five-day mobile multi-phase extraction (MMPE) event in December 2001. Free product was not observed following the MMPE event until September 24, 2008 when 0.05 feet of free product was measured in MW-2. Sixteen water supply wells have been identified within 1,000 feet of the site. The water supply wells are illustrated in Figure 4. Municipal water is not present in the vicinity of the subject site. The nearest surface water body to the site is an intermittent stream approximately 230 feet east of the source area. S&ME’s conducted a sampling event on October 2009 sampling event. The laboratory analytical results from that sampling event indicated that groundwater from MW-2, MW- 3, MW-4, MW-5, RW-5 and WSW-5 contained petroleum constituents at concentrations above 2L Standards. The highest concentrations were detected in monitor wells MW-2 and MW-3. Concentrations on sampled wells did not exceed the Gross Contaminant Levels The site and vicinity are shown in Figure 1, and the site and pertinent features are shown on Figure 2. 3 GROUNDWATER MONITORING S&ME, Inc. (S&ME) submits this Monitoring Report for the above referenced site. The report was prepared in accordance with Contract # 16-1713-2C for the Central Region, and S&ME’s Proposal Number 1354-22583-10 dated February 4, 2010, as approved with NCDENR’s Task Authorization (TA) #02 on February 23, 2010. The scope of the approved TA included in part, the sampling and analysis of groundwater from eight monitor wells (MW-2 through MW-8, and RW-5) and one water supply well (WSW-1 2 Monitoring Report – NCDENR Incident No.9547 S&ME Project No. 1354-09-220A Jerry’s Place, State Road, Surry County NC June 14, 2010 through WSW-5), the installation of five well booms (MW-2, MW-3, MW-4, MW-5 and RW-5), and reporting of the results. 3.1 Monitor Well Sampling On April 22, 2010, S&ME was on-site to gauge depth-to-water and collect groundwater samples from eight monitor wells (MW-2 through MW-8, and RW-5). The depth-to- water measurements were gauged from the top-of-casing. The depth to the groundwater surface ranged from 3.38 (MW-5) to 21.83 (MW-7) feet below top of casing. A summary of groundwater levels and elevations is included in Table 1. The groundwater elevations with equipotentials are depicted on Figure 2. The data indicate groundwater flow to be to the south-southeast. After measuring the depth-to-water, S&ME personnel purged the monitor wells with a dedicated disposable polyethylene bailer by evacuating three well volumes, or until the well was dry. After completing the well purging and allowing groundwater to recover in the monitor wells, S&ME personnel collected a groundwater sample from each of the monitor wells. The groundwater samples were placed in laboratory-supplied containers, stored in a cooler with ice, and shipped under chain-of-custody procedures to Prism Laboratories, Inc. (Prism) a North Carolina certified laboratory for laboratory analysis. The groundwater samples were analyzed for VOCs by EPA Method 6200B. 3.2 Well Booms Following sample collection, S&ME replaced the well booms (Universal Remediation Inc., Petroleum Remediation Product) in monitor wells MW-2, MW-3, MW-4, MW-5 and RW-5. 3.3 Monitor Well Sampling Results The laboratory analytical results indicated that groundwater from MW-2, MW-3, MW-4, and RW-5 contains petroleum constituents at concentrations above 2L Standards. The highest concentrations were detected in monitor wells MW-2 and MW-3. Concentrations do not exceed the Gross Contaminant Levels. Compared to the concentrations from the October 2009 results, concentrations increased in MW-2 (56%) and MW-3 (6%) and decreased in MW-4 (65%), MW-5 (98%) and RW-5 (60%). A summary of groundwater analytical results and a comparison to NCDENR’s regulatory standards is included on Table 2. A copy of the laboratory analytical results and chain- of-custody form is included in Appendix I. Well Sampling Forms are included in Appendix II. 3.4 Water Supply Well Sampling On April 22, 2010, S&ME was on-site to collect water supply samples from supply wells WSW-1, WSW-2, WSW-3, WSW-4, WSW-5 and WSW-6. We were not able to collect a sample from WSW-1 (vacant property with no power), thus WSW-13 (located on adjacent property) was sampled instead. The locations of water supply wells are 3 Monitoring Report – NCDENR Incident No.9547 S&ME Project No. 1354-09-220A Jerry’s Place, State Road, Surry County NC June 14, 2010 4 indicated on Figure 4. No contaminants were detected above the laboratory reporting limits in the sampled water supply wells, except for MTBE (2.9µg/L) in WSW-5. This well contained several petroleum contaminants in October 2009. 4 CONCLUSIONS AND RECOMMENDATIONS A groundwater monitoring event was conducted at the Jerry’s Place property located at Lindell and Pope Farm Road, Surry County North Carolina to assess current petroleum impact to groundwater. The findings at the site are as follows: • Contaminant concentrations from the April 22, 2010 sampling event exceed the 15A NCAC 2L groundwater quality standards in MW-2, MW-3, MW-4 and RW-5. Contaminant concentrations generally decreased in all wells from the October 2009 sampling event, with the exception of MW-2 and MW-3 where concentrations generally increased for most contaminants. • Of the five water supply wells sampled, one (WSW-5) well contained one contaminant at a concentration below the 2L Standard. This well is not used for drinking water. • An intermittent stream is located approximately 230 feet east of the source area. • The depth to the groundwater surface ranged from approximately 3.38 (MW-5) to 21.83 (MW-7) feet below top of casing across the site. Groundwater flow is indicated to be to the south-southeast. Based on the findings presented in this report, S&ME recommends the following for October 2010: 1. Sample WSW-3, 4, 5 and 6 on a semi-annual basis with the next event to occur in October 2010.
