Box' 466` <br /> Hanford, CA 93232 <br /> FORMER FAST GAS STATION 800 EAST HIGHWAY 12, LODI - REQUEST FOR GROUND WATER <br /> MONITORING PROPOSAL <br /> We recently reviewed our files for this site. Due to the steady decline in the <br /> water table in this area of San Joaquin County, nearly all the ground water <br /> monitoring wells for this site have gone dry. <br /> Although the vapor extraction system for this site appears to be effectively <br /> removing volatile hydrocarbons from the subsurface, it will still be necessary <br /> to monitor ground water to evaluate the extent of contamination and the <br /> effectiveness of the remedial action. Therefore, we request that you submit a <br /> proposal for monitoring ground water. This proposal should include planned <br /> monitoring well locations for defining the aerial extent of the plume, and for <br /> monitoring hydrocarbon concentrations within the plume. <br /> 90 lease the requested �o osai to this office and to the San <br /> By 28 September 19 p q P P <br /> Joaquin County Department of Public Health Services. <br /> If you have any questions, please call me at (916) 361-5731 . <br /> THOMAS D.
