Final Remedial Plan 3 September 1992 <br /> 3788 Tracy Boulevard Rev. : D1 <br />' Tracy, California P1745R005.WP <br /> semivolatile organic substances. Kaprealian Engineering, who <br /> performed this work, reported that none of these substances were <br /> detected. The samples were analyzed for the metals cadmium, <br />' chromium, lead, and zinc, without any abnormal findings. <br />' In July, 1991, Mittelhauser Corporation commenced Phase <br /> II investigation of the property, including installing four <br />' monitoring wells. Twelve additional soil borings were drilled in <br /> order to sample soil at locations of concern. Locations of these <br /> borings and wells are shown in Figure 2 . Soil obtained from <br />' drilling at the 16 locations was analyzed for total petroleum <br /> hydrocarbon as gasoline (TPH-G) , total petroleum hydrocarbon as <br />' diesel (TPH-D) , BTEX, and for total oil and grease (TOG) . Results <br /> of the laboratory analyses of these soil samples may be found in <br /> Table 2 . <br />' The subsurface investigation revealed: (A) oil- <br /> contaminated soil remaining adjacent to the former waste-oil tank, <br /> estimated at 78 cubic yards; (B) oil-contaminated soil at shallow <br />' depth adjacent to above-ground waste-oil storage drums, estimated <br /> at 23 cubic yards; and (C) gasoline-contaminated soil adjacent to <br />' the filler-pipe of the southern UST, impacting a volume of soil <br /> estimated at 500 cubic yards. <br /> INo contamination was identified elsewhere on the site. <br /> Soil underlying the service-bay, sump area of the building was <br />' analyzed additionally for chlorinated solvents and for 17 priority <br /> pollutant metals. No solvents were detected. Metals were present <br /> in approximately the abundances in which they occur naturally in <br /> soil. <br /> Following installation and development of the four <br /> groundwater monitoring wells, water samples were collected and then <br />
