SUMMARY11 <br /> The Frank C, Alegre Trucking, Inc. property <br /> located at 802 N. Cluff Avenue, Lodi', California had four <br /> USTs removed in July, 1990. The presence of hydrocarbon <br /> contamination was found below the tanks. A Phase I <br /> Investigation performed by Condor Earth Technologies, Inc. <br /> included excavation of contaminated soil at the site. A <br /> Phase II Investigation conducted by Enexco/GeoPlus <br /> Consulting Services consisted of the installation of three,p <br /> monitoring wells to a depth of 55' . . The three borings were <br /> augered and samples retrieved to investigate the vertical <br /> and .lateral extent of the contaminant at the tank site and <br /> its potential impact to the ground water found at the depth <br /> of about 45' . Chemical analysis showed a no detectJon of <br /> hydrocarbon contamination in the soi'1 or water samples. Its <br /> is concluded that the contaminated soil has been adequately <br /> r excavated and that there has been no''lGimpact to the ground <br /> water. With the removal of the USTs!I, the excavation of the <br /> contaminated soil, and the installation of ground water <br /> monitoring wells, the site has been 'adequately evaluated and <br /> mitigated regarding the environmental risk to human health'; <br /> and sz.fety. No additional investigaition is recommended in' <br /> order to adequately evaluate the depth and lateral limits of <br /> the contamination and its impact on the groundwater. As a` <br /> result of this Phase II Investigation, destruction of the <br /> monitoring wells and a site closure is recommended.
