Problems/Comments
Petroleum contamination discovered during removal of two 15,000-gallon underground storage tanks used to heat the school building. The tanks were installed in 1971 and were taken out of service approximately 5 years prior to removal. Sampling results indicate virtually all contaminated soil was removed, however, 800 cubic yards of contaminated soil remain stockpiled on a 10 mil liner at the City of Tanana old dumpsite on the west end of town. Landfarming is the approved method for remediating the stockpiled soil.
