G. Spanos Construction on July 15, <br /> 1993 concerning the above noted site. In attendance at the meeting were San Joaquin County Public <br /> Health Services, Environmental Health Division (PHS/EHD) representatives Diane Hinson, Margaret <br /> Lagorio and Linda T urkatte, Chevron representatives Brett Hunter and Bette Owen, and property owner <br /> representatives George Spanos, Bill Filios and William Barbour. <br /> T'he soil sample results from the May 1993 over-excavation activities, documented in the report "Soil <br /> Excavation and Remediation", dated June 15, 1993, indicate that the bulk of the gasoline impacted soils <br /> have been removed. Based on these results it appears that the soil remediation at this site has been <br /> completed and that no further remedial or removal action for the soil is required. As no further soil <br /> removal is warranted, future commercial development of the property should not interfere in any remedial <br /> actions for the groundwater, if found to be necessary at this site. <br /> PHS/EHD cannot concur with the request in the report for site closure at this time. The most recent <br /> groundwater sample results indicate low levels of hydrocarbons in the groundwater at the site. Although <br /> the main source of the contamination has been removed, additional data is needed to determine the degree <br /> of the remaining residual contamination and the potential future impact to groundwater it may pose. <br /> Various options to obtain this data were discussed at the meeting. It was decided to obtain soil samples <br /> from selected monitoring wells at the site that are to be destroyed to allow for future development of the <br /> property. A soil sample will be collected from the bottom of the selected borings (MW#1, MW#2, <br /> MW#3, MW#4, MW#5 and MW#6) after the wells are overdrilled and prior to their abandonment. This <br /> data may indicate any residual contamination that may be remaining in the unsaturated soils directly above <br /> the water table. The remaining monitoring wells are to be sampled for at least two additional quarters to <br /> obtain data that may indicate a stable or decreasing groundwater contaminant concentration trend or <br /> pattern. <br /> A Division of San Joaquin County Heakh Care Services <br />
