There <br /> was a reported,'1 1/2 in. by 1/4 in. hole in the tank bottom leaking gasoline at the time of tank <br /> removal. The tank pit was over excavated to about 13 feet, but gasoline was still reported to be <br /> present at the bottom of the excavation. This was documented in a 2/14/85 San Joaquin County <br /> Inspection Report. There is no indication that soil samples from the tank bottomwere collected <br /> for analysis after the tank removal, nor has a closure report been located. <br /> A twenty-one foot soil boring (B1) was drilled adjacent to the former tank excavatiomon 2/19/85.1 <br /> A fifteen foot sample was analyzed for benzene, toluene and xylene(BTX), and the remaining <br /> peaks quantitated against the benzene standard. See attached tables for analytical test results. <br /> A twenty foot soil boring (132) was drilled through the former tank pit on 2/27/85:' A seventeen <br /> and an eighteen foot samples were analyzed for.BTX and TPH. <br /> 5016J1 i <br /> 4231 Pacific Street• Surae 7 1A Rocklin.
