Sur+ace-6" : Sandv loam. <br /> 6"-rte '. . fairly clayey loam, +axrly dry , t irm, grading <br /> to brownish-gray towards the east end of the pit. <br /> 6 -bottom: Sandy, clayey silts , buff to tan , with occassional pods <br /> and irregular shaped inclusions of brownish clay. <br /> No continous, uniform beds were noted , and the sediments were firm <br /> and well compacted; there was no evidence of slumping or caving. <br /> Refer to Plate XI for photos of the excavation. <br /> The SJLHD representative, Mr . knoll , arrived at approximately <br /> l : (_)(:)PM, and after some discussion , it was agreed to take a total of <br /> 7 samples-2 from the bottom, and S si dewal l s. Refer to Plates IX & <br /> X for the appro,:i mate location of the samples. <br /> A Thorpe Oil Co. employee was lowered to the bottom of the <br /> excavation in the backhoe bucket. Using properly cleaned and sealed <br /> brass tubes supplied by FGL. Environmental personel , he took two <br /> samples at each of the locations indicated by Mr . FnolI & Mr. <br /> Hunter . The samples were qui.ci, ly returned to the surface, properly <br /> sealed , labeled , and refrigerated. They were transported to the <br /> laboratory under- Chain--(:)+-Custody; (refer to E..hiblt H. ) A faint <br /> gasolone odor was noted in some of the samples , but no free product <br /> was observed. <br /> Composite samples were also taken by FGL Environmental from the <br /> spoil , to assist in evaluating remediation techniques if needed. <br /> See Plate III for the results of that analysis. The e •cavation was <br /> securely fenced and the spoil was covered with plastic. <br /> RESULTS OF SAMPLE ANALYSIS <br /> rhe results of the laboratory anlysis performed on the above samples <br /> from the excavation are tabulated on Table II . The analysis <br /> revealed that the .w. sidewall samples on the northeast , east , and <br /> soLttheast side of till pit were clean. Very small amounts of BTX&E <br /> were measured in the two bottom samples; TFH-G was detected in only <br /> one sample, ( SW-^W. ) Neither Ethylene Dibromide nor organic lead <br /> were detected at reporting limits in any of the samples. <br /> However , samples No. SW-2W & SW-314, (refer to Plates IX X, ) <br /> indicate that contamination has not been removed in that area, and <br /> will require further cleanup . <br /> Although the composite samples of the spoil taken on 1/19/9(:) showed <br /> detectable levels of DTX&E and TPH-G, EDB was below the reporting <br /> limit of . 010 mg/[,q. The test for lead was not run. The composite <br /> samples taken from the spoil at the conclusion of the excavation <br /> 4 <br />
