Lawsuit wants tough PFAS drinking water standards scrapped
Lawyers for 3M, a farmer and several others urged a judge Friday to scrap drinking water standards in the state that go far beyond federal limits for toxic chemicals once used in firefighting foam and nonstick cookware.
The group sued the state’s Department of Environmental Resources Commissioner Robert Scott last month, alleging the state didn’t follow the appropriate process in approving the standard earlier this year for perfluoroalkyl and polyfluoroalkyl substances, collectively called PFAS. The state denied wrongdoing.
The New Hampshire standard limits one chemical to a maximum of 12 parts per trillion and another to 15 parts per trillion, far lower than the 70 parts per trillion the Environmental Protection Agency has advised for the chemicals.
