'Wendy Cohen -4 - 23 October 2007 <br /> Volpi Farm Property, Stockton <br /> 1,000-gallon gasoline AGT, and dispensers. In 1998, Volpi excavated and removed about <br /> 52.5 tons of TPH-contaminated soil from the Site. In December 1999, Volpi excavated an <br /> additional 300 cubic yards around the gasoline AGT. <br /> Seven groundwater monitoring wells exist at the Site. Groundwater is at a depth of about five <br /> feet bgs with a flow direction of south-southeast to south-southwest. <br /> AGE concluded "low-risk closure" of the site is warranted because of the following: <br /> • Trenches T5, T6, MW-1, and MW-3 define the lateral extent of contaminated soil. The <br /> groundwater pollution is defined to the south by well MW-7, to the east by well MW-2, to <br /> the north by well MW-5, and to the west by well MW-4. <br /> • MW-1 and MW-3 have consistently contained TPH-polluted groundwater, while MW-2 <br /> and MW-4 have had occasional detections. MW-5 through MW-7 have never shown <br /> petroleum hydrocarbon pollution. <br /> • Natural attenuation has likely reduced the concentrations in groundwater. <br /> • No public or domestic wells are threatened. The onsite domestic well is upgradient of <br /> the groundwater pollution. <br /> • Fate and transport study of the contaminated soil and groundwater plume predict that <br /> the concentrations will not affect a shallow downgradient well within 130 feet of the <br /> source area. <br />
