The bottom of the tank , <br /> pit was at 7 feet. The contractor, Majestic, excavated down to 12 feet. The PHS/EHD <br /> inspector, P.Violett, noted that there was still strong evidence of contamination on the <br /> bottom, north sidewall, and in the area of the dispenser. The stockpile samples (2 <br /> composited into 1) showed evidence of contamination. After sampling was completed, the <br /> pit was lined with visqueen and the stockpiled soil returned to the tank pit. The inspector <br /> further noted that the tank had many holes throughout. <br /> Sample ID Depth TPH-diesel benzene toluene ethylben xylene <br /> T-1 13 feet 4140 <.005 <.005 3.2 8.6 <br /> North wall 7 feet 1880 <.005 <.005 0.03 0.11 <br /> (NW1) 7 <br /> stockpile 3710 <.005 <.005 0.06 0.34 <br /> Note: all sample results in ppm (mg/kg) <br /> The tank was disposed of at Leavy Iron Metal, 2727 S.
