Hearing held to discuss PFAS contamination in New Hampshire

LITCHFIELD, N.H. (AP) A top environmental official in New Hampshire has told a Congressional hearing that the federal government should be leading the way in setting standards for a class of toxic chemicals that has caused widespread contamination in the state.

New Hampshire last month enacted some of the toughest standards for compounds known as per- and polyfluoroalkyl substances or PFAS. The state now has the lowest standard for one contaminant known as PFOA and the second-lowest for another known as PFOS after New Jersey.

Department of Environmental Services Assistant Commissioner Clark Freise told Tuesday's field hearing chaired by Democratic Reps. Annie Kuster and Chris Pappas that states don't have resources to regulate all these chemicals. He says the federal government should be examining how to regulate the thousands of known PFAS compounds as a family and setting standards.
