I <br /> NOTICE OF FIELD INVEST16,ATION <br /> TO REMEDIATE SOIL CONTAIV�IINATION <br /> i; <br /> DON'S BUGGIE SIIOA <br /> 3245 Wilson Way <br /> Stockton,California <br /> i <br /> EXECUTIVE SUMMA,Y <br /> �U <br /> Don's Buggie Shop, located at the intersection of Wilson Way, Alpine Avenue, and <br /> Belvedere Avenue, is the site of a proposed investigation of petroleum-contaminated soil. <br /> An underground storage tank for gasoline was removed frim the'property in February 1991, <br /> and soil samples were collected after the tank was removed. Gasoline, benzene, toluene, <br /> ethylbenzene, and xylene were detected in these samples: at concentrations reaching 6,600 <br /> parts per million (ppm), 4.9 ppm, 98 ppm, 73 ppm, and 54ppm, respectively.Motor oil was <br /> also present in an underground sump on the property.. e presence of these chemicals <br /> indicated that an unauthorized release of hydrocarbons h&d occurred, and the San Joaquin <br /> County Public Health Service (EnvironmentalHealth ! ivision) has requested further <br /> investigation and clean-up at the site. <br /> Geological Audit Services (GeoAudit) has been retained to excavate the contaminated soil, <br /> if possible, and replace it with clean fill material. At the! present time, the volume of soil <br /> that must be removed is unknown.; however, due to space limitations, it would not be <br /> feasible to remove more than about 1,800 cubic yards. Thep resulting hole would measure 40 <br /> feet by 40 feet by 30 feet deep. The excavated soil will teN porariy be covered and stored <br /> d <br /> on plastic sheeting at the site until samples have been analyzed at a state-certified <br /> laboratory. Laboratory results are expected within one week after sample collection. After <br /> results have been received, the excavated soil will be transported to a. landfill -and the <br /> excavation will be filled. <br /> I <br /> i <br /> ;i <br /> ;i <br /> I <br /> i <br />
