MacArthur Rd. <br /> Tracy CA 95376 <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) has reviewed the <br /> Phase II Investigation Evaluation report dated August 29, 1991, submitted by American Environment <br /> Management Services and has the following comments. <br /> The content presented within the leaching potential analysis worksheet does not accurately represent the <br /> status of the site. Consequently,we do not agree with your consultant's conclusion that"no further work <br /> and permanent closure.." is recommended. <br /> The analytical soil results from your recent assessment confirm the presence of contaminants that exceeded <br /> allowable limits of the leaching potential as recommended by the LUFT Manual'. This site cannot be <br /> recommended for final closure without further investigation. <br /> Due to the proximity of groundwater and the high levels of total petroleum hydrocarbons, a groundwater <br /> investigation will be necessary in order to determine whether groundwater has been impacted. <br /> Please follow the Tri-Regional Guidelines report specific requirements found in Appendix A, Part A, "Soil <br /> Contamination Problems"when submitting future work plan/proposals prior to any further work at the site. <br /> If you have any questions or concerns, contact Michael Infurna, REHS, of my staff at (209)468-3454. <br /> Jogi Khanna, M.D., M.P.H. <br /> Health Offic <br /> urie A.
