the backhoe for loading into dump trucks. The hole was left open pending sampling_ The excavator ramped into the site of the 10, 000 gallon UST from the east side in order to chase the contamination encountered on the west side during earlier work. Removed soil was placed on the ground adjacent to the site for later disposal . Obvious con- tamination was noted as excavating proceeded The excavator reached a depth of about 27 ' below grade, it could not go deeper without more extensive ramping. Contamination was still apparent at that depth, especially in lenses of blue-gray sandy clay Although the odor was that of petroleum, the bluish color was due primarily to native material, and not contamination. Linda Turkatte & Ron Rowe of the San Joaquin County EHD arrived on site to observe activities. Since it was not possible to excavate deeper without additional ramping in, it was agreed to take soil samples at this time. A 24 TAT would be requested in order to determine what additional work would be required_ Four (4) samples were taken as directed by Linda Turkatte by scraping native material into the excavator bucket operated by Martin Thorpe. The samples were taken from the teeth of the excavator bucket by Fred Sav of GeoAnalytical Laboratories by pushing a clean metal tube into the material . The tube was promptly sealed with foil & plastic end caps, secured with duct tape, labeled & placed in a sealed ice chest pending transport to the laboratory The approximate locations of the samples are shown on PLATE IX_ Instructions were given to analyze for BTEX & TPH, (kerosene, diesel, & motor oil. ) The geologist left for another appointment, and after completion of sampling activities, operations were suspended pending results of the laboratory work. The results of the laboratory analysis revealed that the sample taken from 27' revealed the presence of ethylbenzene at .013 mg/kg, xylene at . 051 mg/kg, and diesel at 270 mg/kg. No other constituents were detected in any of the samples The laboratory results are summarized on TABLE VII ; the worksheets & chain of custody are included as EXHIBIT E December 15 1994 - Jim Thorpe Oil equipment was mobilized again, and Martin Thorpe began moving soil in order to ramp the excava- tor deeper into the north site from the east, end. Jamie Thorpe was using the backhoe to separate the removed soil into clean & "dirty. " The contaminated soil was hauled to Forward, Inc. , for disposal, and the clean soil was used to backfill part of the south excavation_ As the excavator worked deeper, the visable & olfactory evidence 5
