site, and placed it on plastic. The dimensions of the main <br /> excavation at this time were approximately 12 ' wide, (N-S, ) 12 ' <br /> long, and 12' deep. A smaller area at the west end was about 5 ' <br /> x 5 ' x 5 ' ; there had been no evidence of any staining or odors <br /> from that area. After removing some slough from the bottom of <br /> the excavation, an examination of the spoil from the teeth of the <br /> backhoe bucket indicated that most of the contamination was <br /> removed, but some minor odors were still detected. After <br /> consulting with Mr. Collins of the County EHD department, it was <br /> decided that some additional spoil should be removed prior to <br /> obtaining samples for analysis. <br /> Final excavation: <br /> On March 30 & 317 1992, Jim Thorpe Oil removed additional spoil <br /> from the UST site, which produced a final size of 15' x 15' x 16' <br /> deep; (see Plates VIII & IX. ) Mr. Hunter arrived on location at <br /> 1:30PM, and after consulting with the EHD representative, agreed <br /> that all evidence of contamination appeared to have been removed, <br /> and that soil samples should be taken. A total of 6 samples were <br /> taken from the teeth of the backhoe bucket by Mr. Hunter, by <br /> driving 2 1/2" x 3" brass tubes into the soil , promptly sealing <br /> the ends with teflon tape and plastic end caps, wrapping the caps <br /> with duct tape, labeling them, and placing them on crushed ice in <br /> a suitable container supplied by the geologist. The soil <br /> consisted of tan to brown clay, slightly plastic, damp, fairly <br /> friable, with occassional sand grains. There was no evidence of <br /> staining or odors in any of the samples. Two samples were taken <br /> from the bottom of the excavation at a depth of 16 ' , and one <br /> sample was taken from each of the four sides at a depth of 12' ; <br /> Plate Ili shows the approximate locations. <br /> The spoil pile was sampled by obtaining 3 composite samples from <br /> each end and the middle of the pile. They were promptly sealed, <br /> labeled and placed on ice for preservation. The spoil was stored <br /> on plastic placed on asphalt and thoroughly covered with heavy <br /> tJ black plastic. The spoil pile measured 62' long, 18' wide, and <br /> about 6 ' high, and was calculated to contain approximately 100 <br /> cubic yards of material . The excavation was left open pending <br /> the results of the laboratory analysis. <br /> Mr. Hunter transported the preserved soil samples to FGL Environ- <br /> mental for analysis under proper chain-of-custody, with instruct- <br /> ions to test for BTEX & TPH-G using LUFT manual procedures and <br /> detection limits. <br /> RESULTS OF LABORATORY ANALYSIS: Laboratory analysis of the 6 soil <br /> samples from the excavation and the 3 composite samples from the <br /> 4 <br />
