The contamination was identified by characteristic odor, and physical properties typical of hydrocarbon contaminated soil which included staining and dark colored fuel con ained within the latticework of the soil. Limited exploratory trenching was conductec under both tanks. Hydrocarbon stained soil was found to be present under Tank 1 at a depth of 14 feet below ground surface. Hydrocarbon contaminated soil was four d to be present at a depth of 5 feet below ground surface at Tank 2. At the conclusion of the tank removals, both tanks were stored on site.
