5, and W-6). Approximate locations of these borings and wells are shown on Figure 2. Results appeared to define the extent of soil contamination and indicated that petroleum hydrocarbons exist primarily in the area of the former tanks to a depth of 30 to 35 feet below ground surface (bgs). In December 1993, an additional assessment was conducted by SECOR to verify the extent of petroleum hydrocarbons in soil at the Site. This investigation involved drilling five soil borings, and construction of two vapor extraction/inlet wells(W-7, W-8). During this investigation unanticipated impacts were found to exist outside of the former tank bed. In December 1994, an additional assessment was conducted by SECOR to further evaluate the extent of petroleum hydrocarbons in soil and groundwater at the Site. This investigation involved drilling five soil borings, and construction of four groundwater monitor wells (MW-1 through MW-4). In July 1996, an additional assessment was conducted by SECOR to further evaluate the extent of subsurface petroleum hydrocarbons on and off the Site. This investigation involved drilling six soil borings, and construction of six groundwater monitor wells (MW-5 through MW-10). In March 1998, a soil vapor extraction (SVE) feasibility test was conducted by SECOR. Results of the SVE test suggested that soil vapor extraction would be an effective remedial approach for this site. In September 1998, a CAP was prepared for this site by SECOR. This report summarized site- specific data collected to date, contained a Risk-Based Corrective Action evaluation to determine alternative soil and groundwater cleanup levels, compared remediation alternatives for the Site, and contained a conceptual design of the recommended remediation alternative.
