"A New Hampshire judge ordered that the state suspend at year’s end enforcement of its new rules tightening allowable limits on fluorinated “forever” chemicals, as the 3M company had asked.

On Oct. 1, New Hampshire dropped its allowable limit of per- and polyfluoroalkyl substances (PFAS) from 70 parts per trillion to 18 parts per trillion in drinking water and groundwater.

The 3M company, a manufacturer of PFAS compounds, filed suit and sought an injunction to halt the enforcement of the lower limits. A local farmer, the town of Plymouth, and a sludge company joined 3M in the suit, filed in New Hampshire Superior Court."
