Buena Vista LOP SITE: 0001714 <br /> Stockton, Ca. 95203 <br /> San Joaquin County Environmental Health Department (EHD) is the lead agency <br /> providing oversight for investigations and cleanup of releases from underground <br /> storage tanks (UST) within San Joaquin County. In February 1987, a 1000 <br /> gallon gasoline UST was removed from the above referencgd site and petroleum <br /> odor to the soil was observed by EHD staff. The test results of the soil sample <br /> collected at the time of the UST removal were non detect for contaminants but <br /> the laboratory detection levels were elevated. In a letter dated February 18, <br /> 1994, EHD informed Servisoft of Central Valley that further investigation would <br /> be necessary to get site closure certification. <br /> An environmental site assessment was conducted on February 25, 2005. Soil <br /> and groundwater samples were collected and their analysis confirmed <br /> contamination existed in the area of the former UST. Therefore, EHD placed the <br /> site in the EHD Local Oversight Program. The groundwater sample analytical <br /> results evidenced Total Petroleum Hydrocarbons as gasoline, benzene, toluene, <br /> ethyl-benzene and xylene. <br /> A work plan to define the vertical and lateral extent of soil and groundwater <br /> contamination caused by the unauthorized release from the UST must be <br /> submitted by July 1, 2005. <br /> Also, a receptor survey of domestic, municipal, agricultural, industrial and any <br /> other wells within a 2,000 foot radius of this site must be conducted. Contact the <br /> Department of Water Resources, municipal suppliers and any other sources to <br /> identify nearby wells. Submit the results of the survey in a report which provides <br /> the addresses of any wells identified, their location on a map, any known <br /> construction details of any wells found and an evaluation of their pumping <br /> influence with respect to the possibility of contaminant migration and public <br /> and/or environmental health threat. <br />
