However, <br /> on April 7, 1995 depth to groundwater was'measured to be approximately 110 feet <br /> bgs in the domestic well. Construction `details of this well are not known. San <br /> Joaquin County Flood Control Maps for Spring 1986 (consid&ed year of high <br /> water occurrence) show the depth to groundwater to.be approximately 90 feet bgs. <br /> We suspect that regional groundwater flows to the southwest based on the <br /> contour lines of the Flood Control Maps.. <br /> 3.3 Hydrocarbon Distribution in the Soil <br /> Laboratory analyses of soil samples suggest that the vertical extent of soil <br /> impacted with gasoline range petroleum hydrocarbons is above 70 feet-bgs. The <br /> lateral extent has been defined to the south and west. This data is summarized <br /> and shown as Table 1. Copies of the laboratory analytical reports are attached as <br /> Appendix A. <br /> L <br /> L <br /> L <br />
