Groups representing municipalities and businesses are trying to put the brakes on New Hampshire’s efforts to impose some of the nation’s toughest drinking water standards for a class of toxic chemicals that have caused widespread contamination in the state.
Last month, the Department of Environmental Services filed a proposal to set maximum levels for several compounds known as per- and polyfluoroalykyl substances, collectively called PFAS. New Hampshire is proposing a maximum of 12 parts per trillion for one of the contaminants called PFOA and 15 parts per trillion for another called PFOS.
