HANOVER, N.H. (AP) - The U.S Army Corps of Engineers has come up with a way to treat contaminated soil at the Army’s Cold Regions Research and Engineering Lab in Hanover, New Hampshire.
The chemical, trichloroethylene, or TCE, was used for years as a coolant at the lab. It leaked into the soil.
Vermont Public Radio reports (https://bit.ly/1958sHq) the Corps has been able to pinpoint where TCE could be entering buildings. It has installed an exhaust system similar to fans used to remove radon. Blowers sent the TCE through carbon filters outside.
The Corps also is working on a way to remove the chemical from soil itself.
Army Corps spokesman Darrell Moore says workers are safe from TCE contamination, and that neighboring buildings, including a day care center and middle school, have passed environmental tests.
