Problems/Comments
Diesel fuel contamination from abandoned underground fuel storage tanks, most related to heating fuel.
The Building 2674 warehouse foundation was located and cut UST-type piping was observed suggesting that an UST had been removed from this location in the past. 130 cubic yards of impacted soil was removed in 1997. Confirmation sampling indicated DRO up to 1700 mg/kg. Amaknak and Unalaska Islands were used by the military during World War II. The Japanese bombed Dutch Harbor and Fort Mears in 1941. Following the bombing the military dispersed its troops moving back up into Unalaska Valley and Pyramid Valley to minimize the potential for damage if future air raids occurred.
The Corps of Engineers had a contractor tear down the abandoned buildings and debris and dispose of them in various landfills during the mid - late 1980s. Underground fuel tanks were abandoned in place. In the mid-1990s the Corps started working on the sites again under the Formerly Used Defense Sites (FUDS) program. Site inspections were done around the former buildings to look for remaining underground fuel tanks and other potential contaminant sources.
