a) Enhanced Bioremediation <br /> b) Soil Vapor Extraction (SVE) <br /> c) SVE in conjunction with Air Sparging for groundwater treatment <br /> 3) A Site Receptor Survey This would involve contacting utility companies, government <br /> agencies, and perhaps local businesses to obtain information about any potential <br /> contaminant receptors (sewer lines, wells, etc ) within 2000 feet of the site <br /> In addition, in a letter dated March 9, 1999, PHS/EHD requested Valley Motors to submit a work <br /> plan to define the extent of groundwater contamination in the site area The existing; data are <br /> sufficient to define the extent of contamination on the Valley Motors property, but the data also <br /> indicate that groundwater contamination extends off site to the west (beneath Grant Street) and <br /> off site to the north (toward Main Street) The limits of contamination in these directions are <br /> unknown, and meeting the PHS/EHD request would require installing two additional <br /> groundwater monitoring wells, both of which would be located off site <br /> i <br />• 5 <br />
