Problems/Comments
During the tank removal on September 12, 2008, approximately 80 cubic yards of soil were excavated. Three confirmation soil samples were collected from the depths of the excavation, approximately 16 feet below ground surface at 5 feet below the bottom of the former tank. Three soil samples were also collected from the stockpile. Confirmation soil samples taken in the excavation did not contain contaminants above ADEC cleanup levels. One soil sample taken from the stockpile contained benzene up to 0.0325 mg/kg. No groundwater was encountered in the excavation. The 80 cubic yards of stockpiled soil along with clean fill were used to backfill the excavation.
