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.
