Technical Data Summary <br /> The Southland Co 9 oration 9110 Thornton Road Stockton,CA Aril 4,1995 <br /> F RECOMMENDATIONS <br /> i <br /> Groundwater Technology recommends site closure for the referenced site based on: <br /> ■ Separate-phase hydrocarbons have been removed from the on-site groundwater <br /> monitoring wells in the source area. <br /> ■ Soil confirmation samples did not contain detectable levels of TPH and benzene. Soil <br /> vapor samples contain no detectable benzene. The highest TPHg concentrations in <br /> air sample are under 74 pg/l. <br /> ■ Analytical results from groundwater sampling indicate levels of hydrocarbon <br /> constituents have been at or below California action levels for drinking water since <br /> 1989. <br /> * The surface at the site is capped by uninterrupted asphalt paving, limiting percolation <br /> from precipitation into the underlying soil. <br /> Groundwater Technology requests that the SJCPHS approve closure, and recommend closure to the <br /> CRWQCB-CVR. <br /> Upon approval of site closure, Groundwater Technology will proceed with the abandonment of the on- <br /> site and off-site monitoring wells in accordance with SJCPHS requirements. <br /> ATTACHMENTS <br /> 1.
