Problems/Comments
The Army Hill site is located on a hilltop northeast of the Barrel Disposal Area (Site 23). This site consisted of 46 discarded 55-gallon military fuel drums (2 along the Air Force Road right-of-way and 44 along the hillside). During RAs in 2002 and 2005, 45 of the military fuel drums were removed and approximately 13.25 cubic yards of contaminated soil was excavated from the site. DRO was detected at a concentration of 4,900 mg/kg, and chromium was detected at a concentration of 30 mg/kg. Drums were disposed in the Unalakleet City landfill, and contaminated soil was transported off site for disposal at a permitted landfill. During a 2010 removal action one remaining drum containing approximately 1 gallon of liquid was removed from the site. No hydrocarbon odor or visually impacted soils were encountered during the draining and removal of the drum.
