摘要

The use of the military munition white phosphorus in wetland impact areas has resulted in several documented cases of deposition of residual particles from incomplete combustion. In areas of permanent saturation, such as pond bottoms, these particles are highly persistent. They are also extremely toxic to dabbling waterfowl, which can ingest them through the normal course of sieving bottom sediments during feeding. In Eagle River Flats (ERF), an estuarine salt marsh that serves as a munitions impact area for Fort Richardson, Alaska, particulate white phosphorus has been found to be the cause of large waterfowl dieoffs. After several years of investigations into the distribution and persistence of white phosphorus in the Flats, a method of remediation was developed that incorporates a semi-autonomous floating pump system, designed to temporarily drain contaminated ponds and allow the contaminant to attenuate naturally. Preliminary results over three years of treatability studies indicate that this remediation method is highly effective when climatic conditions are favorable to the dryign of the exposed contaminated sediment. This remediation method was chosen by the U.S. Army, the Alaska Department of Environmental Conservation, and the U.S. Environmental Protection Agency for the ERF Superfund site cleanup action.
