Editor's note: An earlier version of this story reported that elevated PFCs were found in the Franklin Fire Department's drinking water. The chemicals were actually detected in a monitoring well at the department.
At least four New Hampshire fire departments have found an elevated level of toxic chemicals known as PFCs, either in their drinking water or in nearby monitoring wells.
The state says the Kingston and Windham Fire Stations reported elevated levels of PFCs, or perflourinated chemicals, in their well water. Elevated levels were also found in monitoring wells at the Franklin Fire Department and the former fire station at New Boston Air Base.
Those findings come from the 12 departments that have sent test results to the Department of Environmental Services so far, with more expected.
PFCs are found in many man-made substances, including some firefighting foams that can run off into private wells. Some studies have linked PFCs to cancer and other health problems.
The Department of Environmental Services decided last year that New Hampshire drinking water should contain less than 70 parts per trillion of PFCs. The wells in Windham and Kingston were roughly twice that limit.
Four other departments found PFCs under the state limit, and another four didn't find PFCs in their water at all. The DES has not released results from fire training areas or airports.
The state has recommended all fire departments with private wells test for PFCs, and may do more testing in areas with positive results.
