depth was measured at 7 feet No "rainbow" or petroleum sheen <br /> was observed, but a slight film of unknown composition was <br /> apparent on portions of the water As the backhoe worked towards <br />' the southeast side, it encountered a cense of soft, loose, gray <br /> colored sand, which had a definite petroleum odor & apparent <br /> discoloration. As additional material was removed, the evidence <br /> of contamination decreased, and the sand changed to a tan to buff <br />' color, and the odor disappeared. Some evidence of contamination <br /> was still visible on the east wall , and the backhoe operator <br /> repositioned his equipment on the driveway on the east side to <br />' facilitate removal of the material. <br /> Excavation continued on the east side of the pit, the spoil was <br /> placed on the concrete driveway and moved by a front-loader & <br /> placed on plastic at a site to the south of the work area. A <br /> layer of black sticky clay loam at about 4 feet did not show any <br /> evidence of contamination, but the tense of soft sand on the east <br />' & southeast side did have a petroleum odor When exposed to air, <br /> the color changed from a dark gray to a whitish-gray, (caused by <br /> oxidation of the hydrocarbons when exposed to air. ) <br /> As excavation continued on the east & southeast side, all odors <br /> disappeared, and the sand body returned to its' natural tan to <br /> buff color, confirming the removal of the remaining <br /> contamina-tion. PLATE XZ shows photos of that area. <br /> Margaret Lagorio, Sr. REBS from the County EBD, was present <br />' during the final stages of spoil removal. After discussions with <br /> Mr. Hunter, it was agreed to take five (5) 5011 samples from the <br /> sides of the excavation using the following procedure: the <br /> backhoe operator obtained a soil sample at selected locations <br /> using the bucket to remove the material , the geologist pushed a <br /> clean metal tube into the soil on or adjacent to, the teeth of <br /> the bucket; the sample was briefly examined, the ends of the tube <br /> were promptly covered with teflon tape & plastic caps, securely <br /> sealed with duct tape, labeled, and placed on ice for preserva- <br /> tion. <br /> IUsing a clean glass vial, a composite water sample was taken from <br /> two locations in the bottom of the excavation by gently immersing <br /> the container in the water to prevent excessive sediment from <br /> Ientering. The vial was sealed, checked to ensure that no head- <br /> space was present, labeled, and placed on ice for preservation. <br /> Refer to PLATE IX for the locations of those samples. PLATE XII <br /> is a photo showing the excavation after completion of the work. <br /> After completion of the above work, the two spoil piles were <br /> sampled as follows: <br /> I 5 <br /> 1 <br />
