El Dorado <br /> Stockton, Ca. <br /> San Joaquin County Public Health Services,Environmental Health Division(PHS/EHD)placed this site in the Local <br /> UST Oversight Program (LOP) August 1991 for oversight and clean up activities associated with an unauthorized <br /> release of petroleum from an underground storage tank removed on June 6, 1991. <br /> I <br /> Contaminated soil documented/identified at the time of the tank removal was excavated and relocated to an <br /> appropriate facility for disposal. Soil samples taken in the excavation indicated residual contamination existed and j <br /> that a groundwater investigation was warranted. The groundwater investigation was conducted and it revealed j <br /> groundwater had been impacted. Soil samples collected and analyzed from borings indicate there is residual, <br /> localized contaminated soil near the former tank location. <br /> PHS/EHD has agreed with and issued the necessary permits to complete the corrective action taken. This office has <br /> provided oversight and reviewed reports as required. <br /> PHS/EHD is in receipt of the Work Plan Addendum for Hydrocarbon Impacted Soil Assessment dated June 2, 1994 <br /> and has the following comments. The proposed soil boring downgradient of the former tank location and MW#1 4 <br /> will provide additional information as to the horizonal extent of contamination in that direction but does not provide <br /> any further remedial action. Be aware that further active corrective action may be required. <br /> If you have any further questions regarding this matter contact Harlin Knoll, REHS, at (209) 468-3442.
