depth to groundwater. GAS measured product layers of 6.125 and 7.25 inches in MW-1 and <br /> ' MW-2 respectively. GAS did not report observing an immiscible layer on MW-3, but states <br /> that, "water samples were not collected for analysis." GAS reported that groundwater had <br /> dropped approximately five feet since 1988, and, that the groundwater had a relatively flat <br /> gradient with a slight slope to the south. GAS concluded: <br />' * that offsite migration was a possibility; <br /> * the lateral extent of contamination was not yet determined, <br /> * the water bearing unit at 40 feet should allow recovery of the free product and/or <br /> dissolved contamination, <br /> * that a more northerly source may be contributing to the contamination; and, <br /> * that 3,000 to 4,000 gallons of gasoline were potentially present <br /> Based on these conclusions, Falcon Energy extracted and removed several thousand gallons of <br /> impacted groundwater. In January 1994, San Joaquin County Health Services, Environmental <br /> Health Department (SJCEHD) requested that the wells be sampled. This report summarizes the <br /> field activities and analytical results associated with sampling the wells, and presents the <br /> conclusions and recommendations that are based on those results. <br /> I <br />' 2 <br />
