(Ground Zero) on behalf of the above <br /> referenced site and has the following comments. <br /> The report documents the investigation that was conducted at this site on December 10, <br /> 1999. Three soil borings were advanced for the purpose of collecting soil and grab <br /> groundwater samples for analysis. Results of the soil analysis indicate that petroleum <br /> hydrocarbon contamination appears to be limited to the top ten feet of subsurface soils. <br /> The lateral extent of the shallow soil contamination was not been defined. Results of the <br /> groundwater analysis indicate that contaminant impact to groundwater has occurred. <br /> The groundwater contamination has not been defined laterally or vertically. <br /> The report recommends the installation of several groundwater monitoring wells and <br /> possibly more soil borings to delineate the lateral extent of the shallow soil and <br /> groundwater contamination at this site. PHSIEHD agrees with this, and requests that <br /> the vertical extent of the groundwater contamination also be investigated. <br /> Please prepare a work plan to continue the investigation at this site and submit it to <br /> PHSIEHD by June 2, 2000. Please prepare and submit with the work plan a well survey <br /> that documents the locations of all domestic, industrial, agricultural, municipal and other <br /> wells within a 2000-foot radius of the site. If you have any questions or comments call <br /> Lori Duncan at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> bcn CIC{\11�11�t-, <br /> Lori Duncan, Senior REHS Margaret agorio, REHS <br /> LOP/Site Mitigation Unit IV Supervisor, Unit IV <br /> cc: Marty Hartzell, CVRWQCB <br /> John Lane, Ground Zero <br /> A Division of San Joaquin County Health Care Services <br />
