TPH as gasoline was detected as 2, 250 <br /> mg/kg, and 980 mg/kg in samples TK-2S and TK--2N at a depth of <br /> , <br /> 12 feet beneath the north and south ends of the former, <br /> 5, 000 gallon unleaded gasoline tank, respectively. Benzene � <br /> i <br /> was detected in these samples at 5. 905 mg/kg and 1. 665 <br /> I <br /> mg/kg respectively. THP as gasoline was detected in j <br /> sample TK-3N at a depth of 12 feet beneath the north end of i <br /> the 2, 000 g a l l cen premium gasoline tank at a concentration of <br /> 80 mg/kg, but was not detected in sample TK-3S at the south <br /> end of the tank. No volatile aromatics were detected in i <br /> , <br /> • either of these samples. TPH as oil and grease was detected <br /> , <br /> in sample TK-4 at 40 mg/kg, and lead was detected at 25 <br /> mg/kg. Nene of the ether CAM metals were detected at levels <br /> above apparent background concentrations. TPH as gasoline <br /> i <br /> was detected in samples SPIE-1, SPE-2 and SPW from the <br /> i <br /> stockpiled soil at concentrations of 8 mg/kg, 32 mg/kg, and j <br /> 120 mg/kq respectively. Lead was detected in these samples � <br /> I <br /> at 27 mq/1{q, 24 nig/kg, and 15 mq/kg respectively Csee f <br /> attached table 1 and 21 . <br /> i <br /> h <br /> Based on the soil sampling analyses, concentrations of TPH as <br /> gasoline and the volatile ar-::iaiat xcs present in the tank and <br /> pipeline areas, additional site characterization was required <br /> by SJPHS/END.
