(DeIta), has been authorized to conduct an assessment to <br /> evaluate the distribution Of petroleum constituents in soils beneath a Shell Service Si_a'don at 620 West <br /> Charter Way in Stockton, California. The assessment is being conducted prior to excavation and <br /> is <br /> removal of existing underground storage tanks and installation of new tanks. <br /> ! This report presents descriptions of soil conditions underlying the site as discerned by advancing <br /> eight exploratory soil borings. The boring locations were selected to investigate soil conditions <br /> adjacent to existing underground storage tanks and product Iines,and to define an area of soils free <br /> of petroleum constituents :n which the new tanks may be placed. <br /> r i <br /> Purpose <br /> k.5 <br /> The pretank removal soil assessment was undertaken to: <br /> • Determine whether sous adjacent to the existing tank basin contained detectable <br /> F <br /> ` concentrations of petroleum constituents. <br /> rb <br /> • Determine the distribution and extent of these constituents(if present). <br /> t <br /> • Determine whether soils in the area of the new tank basin contained detectable <br /> concentrations of petroleum constituents. <br /> • Evaluate the need for additional investigation. <br /> h <br />
