PHS/EHD has the <br /> following comments for your consideratiori. <br /> i <br /> The report included the results of the soil and groundwater investigation which was continued on June 20, <br /> 1994. Theinvestigation consisted of the drilling and 'sampling of five soil borings, one of which was <br /> converted into monitoring well, MW-9. Significant soil contamination was evidenced. It appears that the <br /> extent of the soil contamination has been defined on site; however, the location and concentration of <br /> contaminants evidenced during the drilling of soil boring, SB-1, suggest that there may be some soil <br /> contamination off site. ! <br /> The results of the groundwater samples collected June 27, 1994 indicate that the extent of the groundwater <br /> contamination has been defined. <br /> As indicated in PHS/EHD's April 7, 1994 correspondence, once the extent of soil and groundwater <br /> contamination has been defined, a final remediation/corrective action plan should be submitted. Please <br /> continue to evaluate alternatives and complete the necessary feasibility studies. The corrective action plan <br /> should be submitted by December 30, 1994. <br /> If you have any questions or comments, please contact me at(209) 468-0337. <br /> Donna Heran, RENS, Director <br /> Environmental Health Division <br /> Mary Meays, Senior REHS Diane M.
