The U.S. Army Corps of Engineers, Alaska District,recently completed the remedial action for the $23-million Drury Gulch Formerly Used Defense Site (FUDS) cleanup project on Kodiak Island.

The 6-acre site was used as an unregulated dump by the U.S. military after World War II. Metal debris including engines from wrecked aircraft and fractured electrical equipment had been reburied over many years. The undocumented history combined with the naturally complex soil and bedrock structure made site investigation and remediation challenging.

Since 2003, the Corps of Engineers has removed more than 19,000 tons of polychlorinated biphenyls (PCB)-contaminated soil and 450 tons of trichloroethylene (TCE)-contaminated soil from land now owned by the U.S. Coast Guard. The containerized soils were transported to the Columbia Ridge landfill in Arlington, OR, for final disposal. The Drury Gulch site was then covered with a minimum of 2-1/2 feet of clean soil graded to blend with the natural ground contours.

The project also realigned a drainage channel to minimize drainage through the site. Per the 2003 Decision Document, the Corps of Engineers will monitor the site for five years and then turn over long-term monitoring to the Coast Guard.

The FUDS cleanup team included the Corps of Engineers and its contractors, Jacobs Engineering and BC Contractors/Jacobs Engineering Joint Venture; the U.S. Coast Guard; the U.S. Environmental Protection Agency; the Alaska Department of Environmental Conservation; and consultants for the environmental agencies.

Site investigations began at Drury Gulch in the mid 1990s,and excavation of contaminated soil began in 2003.
