extended in a southerly direction and parallel to the property line,. The contaminated spoil was placed sepaarately near the site. The backhoe worked down into the pat area from the north , forming a working shelf about 12 ' bgl . The contamination appeared to be restricted to a loose, grayish colored fine-to coarse-grained clayey sand; there was no visible staining , but a definite petroleum odor was apparent on fresh exposures. The operator placed the spoil on the ramp behind the backhoe, and from there it was picked up by a front-loader , placed in a large open truck, and stored on plastic at the location of the spoil from the first excavation. From the ledge at 12 ' , the backhoe operator could excavate to a maximum of 23-24' . There was still some obvious contamination, especially on the southeast side, where a very hard layer of claystone was encountered. However , due to the inability of the equipment to reach further, at was decided to sample the bottom and analyze the results. The geologist collected 2 soil samples from the teeth of the back • hoe bucket using properly prepared brass tubes supplied by the laboratory; refer to Plate VIII for the locations of the samples. The brass tubes were promptly sealed with teflon tape & plastic end caps, and then thoroughly wrapped with duct tape. The brass tubes were labeled and placed on ice for storage. The refrigerated samples were delivered to FGL Environmental by Mr. Hunter under proper chain of custody, with instructions to test for OTEX & TPH--G. A 5 day turnaround time was requested. The results of the laboratory analysis, (Table V, ) revealed very high levels of TPH-G, and significant amounts of Toluene, Ethyl benzene & Xylene. Benzene was not detected at test limits. Since the levels of TP'H-G were higher than detected at shallower depths, it was felt that the hard claystone layer encountered dust below the bottom south sample had caused the residual fuel to be concentrated at that depth. The walls of the excavation were clean, indicating that movement had been essentially vertical . After reviewing available options with the owner and EHD, it was decided that additional excavation appeared to be the best approach for removing the remaining contamination. DETAILS OF FINAL EXCAVATION: On October 9, Thorpe Oil personel moved the metal shed at the north end of the eAcavation and a portion of the fence an the south side i n order to allow further spoil removal . • On October 16, Thorpe Oil personel extended the ramp farther- to 5
