Two new locations in Vermont have been foundto have PFOA and PFOS contamination.
Governor Peter Shumlin announced Thursday that perfluorocarbons were detected at the Vermont Air National Guard base in South Burlington and an underground storage tank at Pittsford Fire Academy.
Both locations have historically used firefighting foam containing the chemicals in training exercises. No drinking water supplies at the locations have been impacted by PFOA or PFOS.
Private wells sampled near Harbour Industries in Shelburne tested clean for both chemicals.
The believed to be cancer-causing chemicals have been detected at sites in Bennington, North Bennington, and Pownal, as well as Hoosick Falls, Petersburgh, and Newburgh, New York.
