Problems/Comments
Two UST's were removed from this site in 1997, one 2,500 gallon diesel tank #SC-01, and one 2,500 gallon gasoline tank #SC-02. In situ samples beneath the dispenser contained up to 6,400 mg/kg DRO, and up to 440 mg/kg GRO. Contaminated soils were placed back in the excavation, no soils were stockpiled. Shannon & Wilson 2003 Corrective Action report indicates that another 180 cubic yards of soil were removed from the former UST location and stockpiled on site. One sample on the west wall of the excavation exceeded Method II Migration to Groundwater Cleanup levels, DRO 3,010 mg/kg. The onsite drinking water well did not contain petroleum hydrocarbon analytes above laboratory PQL's. The soil stockpile was approved for re-use onsite.
