show any apparent contamination. The contaminated sail consisted <br /> of very clayey sand & sandy clay, with lenses of very hard, dense <br /> clay, (hardpan. ) This spoil was not placed in the truck, but was <br /> stored on site pending further profiling. <br /> The remaining clean spoil was placed in the truck, and was trans- <br /> ported to Forward under prior agreement. A total of 2 loads, (.36 <br /> cubic yards, ) wa delivered to the disposal facility; copies of <br /> the receipts for the spoil are attached as Exhibit F. <br /> Excavation continued to a depth of about 20-21 ' , the limit of the <br /> equipment being used. Contamination was still present on the <br /> south and east walls, but work was discontinued due to space <br /> limitations. The dimensions of the excavation at this time were <br /> approximately 32' long, and 12 to 15 ' wide; refer to Plates VI & <br /> VII for details. <br /> Five (5) soil samples were taken from the sides of the excavation <br /> as directed by the RG and Michael Collins of the County EHD using <br /> the excavator bucket. It was not possible to obtain a soil <br /> sample from the bottom at the south end due to depth of the hole. <br /> A 2" X b" brass tube was driven into the spoil collected in the <br /> . bucket by the geologist, briefly described, promptly sealed with <br /> teflon tape and plastic end caps, and then sealed with duct tape. <br /> The metal tubes were then labeled and placed on ice pending <br /> transport to a State Certified laboratory for analysis. The <br /> locations and identifying number of each soil sample is shown on <br /> Plates VI & VIZ. Two (2) composite samples were taken from the <br /> spoil pile for characterization purposes. They were sealed, <br /> labeled and stored with the Bather soil samples. The excavation <br /> was left open pending the results of the laboratory analysis. It <br /> was barracaded off with sawhorses and metal drums and marked with <br /> yellow plastic tape. <br /> Laboratory results of the above work revealed that a minor amount <br /> of contamination was measured from the soil sample taken from the <br /> nbrthwest wall at 10 ' , and high levels of STEX and TPH-G were <br /> detected from the soil samples taken from the southeast and south <br /> walls, (refer to Plates VI a VII for their locations & amounts of <br /> contamination. Table II gives more details of the laboratory <br /> results. <br /> The laboratory results of the composite samples taken from the <br /> spoil pile are tabulated on Tables III & IV. <br /> Exhibit D includes copies of the signed laboratory analysis <br /> sheets for the work done on Nov. 5. <br /> 5 <br />
