Bioremediation consortium to tackle chlorinated solvents

摘要

What experts say are some of the most robust techniques for in situ bioremediation of chlorinated solvents will be demonstrated over the next five years at federal facilities. On August 9 EPA announced a collaboration with the Department of Energy, U.S. Air Force, and a consortium of manufacturers: Monsanto, Dow, DuPont, General Electric, Ciba, and Zeneca Inc. The consortium will demonstrate intrinsic and accelerated anaerobic bioremediation for chlorinated solvents, specifically tetrachloroethylene (PCE) and trichloroethylene (TCE), in groundwater and cometabolic bioventing for TCE in subsurface soils. The demonstration will take place at Dover Air Force Base and an undetermined federal facility. The project will cost about $13 million to $15 million over five years. EPA's cost will be only about $1 million, said Larry Fradkin, Federal Technology Transfer Act Coordinator for EPA's Office of Research and Science Integration.
