N.Y. Initiative Uncovers Need to Mitigate Some Vapor Intrusion

New York in 2005 reopened hundreds of pollution cases to determine whether new science could shed light on old cleanups, particularly with chemical vapors.

Three years later, the Department of Environmental Conservation (DEC) has made significant progress in tracking down and evaluating more than 400 sites, DEC Commissioner Pete Grannis said on March 9.

Thus far, 147 investigations have been completed. Of those, the state found that 19 required mitigation (ventilation systems) to alleviate vapors discovered on-site or in neighboring buildings, 46 required monitoring only, and 82 needed no further action (levels did not trigger mitigation or monitoring). In addition, mitigation has been determined necessary at 11 sites where investigations are still ongoing.
