i 1 29 October 2008 AGE-NC No. 04-1168 Page 3 of 5 • Toluene, ethylbenzene and xylenes were detected in borings BI and B2 at maximum concentrations of 0.017 mg/kg toluene (132-45), 0.017 mg/kg ethylbenzene (B2-45) and 6.3 mg/kg xylenes (132-35). • EDB was detected in one soil sample at a concentration of 0.045 mg/kg(132-35). No other target analytes were detected at or above laboratory detection limits in any of the samples analyzed.On 04 August 2004,AGE published Limited Site Investigation Report which reported all site activities, findings, and recommendations for an investigative work plan. AGE received an EHD directive letter, dated 31 August 2004, notifying the primary responsible party that the site was added to the EHD local oversight program and that a certified professional geologist must be reviewing all reports. AGE received an EHD directive letter, dated 08 January 2005, requiring the submission of an investigative work plan. On 15 March 2005, AGE published Monitoring Well Installation Work Plan which reported all purposed investigative activities,installations,and findings.AGE received an EHD directive letter, dated 05 April 2005, approving the submitted investigative work plan. On 31 May 2005, AGE published a letter, Monitoring Well Installation,which request a 60 day extension for all purposed investigative activities and installations.AGE received an EHD directive letter,dated 08 July 2005, approving the request for a 60 day extension . I i On 20 and 21 July 2005,three soil borings were advanced at the site for collection of soil samples and installation of three ground water monitoring wells (MW-1 through MW-3). The monitoring wells were developed on 25 July 2005, and surveyed on 04 August 2005. On 07 September 2005, 18 waste soil drums from monitoring well installation were removed from site by Slaby Environmental, Inc. Samples were collected from the borings at discrete five-foot intervals.A total of ten soil samples were analyzed for petroleum hydrocarbon products. The following target analytes were detected: • TPH-g was detected in soil samples collected from borings MW 1 and MW2 at concentrations of 1.5 mg/kg(MW1 at 35 feet bsg) and 1.0 mg/kg (MW2 at 50 feet bsg). • Total xylenes were detected in soil samples collected from borings MW 1,MW2 and MW3 at concentrations of 0.086 mg/kg(MW 1 at 35 feet bsg),0.052 mg/kg(MW 1 at 45 feet bsg), 0.046 mg/kg (MW2 at 50 feet bsg), and 0.014 mg/kg(MW3 at 50 feet bsg). No other constituents of concern were detected at or above laboratory detection limits in the samples analyzed. On 10 October 2005 AGE published Monitoring Well Installation and Quarterly Monitoring Report which reported all monitoring well installation site activities, findings, and Advanced GeoEnvironmental
