Problems/Comments

Subsurface petroleum contamination discovered in 1991 at the removal site of two 500 gallon underground storage tanks. One tank contained gasoline, the adjacent diesel tank was discovered to have a leaky return line. The diesel tank was removed and replaced. A monitoring well was established in 1992. A water well search was initiated in 1992. Groundwater impacted, 1995 sample showed 0.02 mg/L benzene, above ADEC sleanup level of 0.005 mg/L. Two local wells and a city fire well were tested as part of an off-site well search and showed no contaminant levels above ADEC cleanup levels. 130 cubic yards of soil were removed and thermally treated in 1993. Excavation was limited by concern for the integrity of the building foundation.
