New Hampshire has voted to put into place some of the country’s toughest drinking water standards for a class of toxic chemicals that were once used in everything from firefighting foam to nonstick cookware but are now raising health concerns.
A joint legislative committee Thursday approved three measures allowing standards for compounds known as per- and polyfluoroalkyl substances, collectively called PFAS, to go into effect. New Hampshire now has the lowest standard for one contaminant known as PFOA and the second lowest for another known as PFOS after New Jersey.
