taLing soil samples. There was no odor or discoloration noted. <br /> Additional asphalt was removed with the back.hoe bucket , and the <br /> e..cavata on was widened to appro;-i motel y 20 long X 15 ' wide, and 15 <br /> deep. No visible contamination or soil discoloration was observed , <br /> but a definite gasoline odor was noted an some of the spoil in the <br /> backhoe bucket. Spoil was placed on plastic on asphalt adjacent to <br /> the pit on the north as shown on Plate VIII . Excavation continued <br /> under the direction of W. J. Hunter , consultant. Harle:n knoll , <br /> SJLHD, arrived at the location at appro; lmately IPM, and observed <br /> the e-cavation process, and examined selected samples. Pockets of <br /> odor were detected , primarily from the south side of the e-cavation , <br /> and occasional free product was observed when spoil samples that had <br /> a distinct odor were examined closely. A slight sheen could be <br /> observed when selected samples were placed in water. All of the <br /> spoil below the top b" was dry; there was no evidence of moisture in <br /> the pit during the excavation operations. Excavation continued <br /> until about 4PM, when it was decided to cease operations until the <br /> 22nd. due to approaching darkness. <br /> At the suggestion of Mr. Knoll , Mr. Brock of FGL Environmental took <br /> 2 samples at three locations from the spoil ; instructions were to <br /> split & ma> the samples to obtain composites, and analyze for BTX&E, <br />• EDEA , TPH--G, and organic lead; refer to Table III for details. <br /> Word resumed on the 22nd , and the e"cavation was deepened and <br /> widened to approximately :;U long X 19 ' wide X 21 deep. Spoil was <br /> placed on plastic , (on asphalt , ) adjacent to the pat on the north as <br /> shown on Plate VIII . Mr. Vnol1 of the SJLHD was present during the <br /> majority of this work . Occasional pockets of odor were detected , <br /> and some manor amounts of what appeared to be liquid were noted when <br /> selected samples were broken open. Some samples e;,hibited a slight <br /> calor or sheen when placed in water. All of the soil below the top <br /> c," were dry; there was no evidence of moisture in the pat during <br /> e cavation. <br /> Because of time constraints , it was agreed to take the soil sample, <br /> the: following day, and operations were suspended. <br /> On January 2:,, 1991.), Thorpe Oil personel removed some loose spoil <br /> from the bottom of the hole preparatory to taring samples. No odor- <br /> was noted prior to, or during the clean -out operation , and no odors <br /> were detected from the spoil . An estimated total of (jO cubic yards <br /> of spoil has been removed from the pat ; it will be covered with <br /> plastic until remediation plans have been formulated. <br /> An examination of the sediments e..posed by the excavation revealed <br /> the following general lithology: <br />
