Energy Department to drill Idaho well to clean up waste

摘要

A well will be drilled early next year at a federal nuclear site in eastern Idaho to remove hazardous waste from a Lake Erie-sized aquifer that supplies water to cities and farms in the region, officials said yesterday.The Energy Department's Office of Environmental Management said the well will be drilled at the north end of the 890-square-mile DOE site that includes the Idaho National Laboratory.Cleanup contractor Fluor Idaho will assist the U.S. Geological Survey in drilling the well to remove waste below the former Test Area North facility. The site sits above the Eastern Snake Plain Aquifer.Officials said the new well is needed to reduce an industrial solvent called trichloroethylene and other organic hazardous compounds.For nearly two decades, crews have been pumping and treating water in the area. Crews have also been injecting a solution into the aquifer to encourage naturally occurring microorganisms to consume the trichloroethylene.
