A federal judge granted final approval to one of the largest settlements involving drinking water contamination: DuPont’s $1.185 billion deal with an estimated 14,000 public water providers across the country.

Thursday’s order entered by U.S. District Judge Richard Gergel, who is overseeing multidistrict litigation involving PFAS, or perfluoroalkyl and polyfluoroalkyl substances, comes after a Dec. 14 final approval hearing. Gergel, who noted that only 924 water providers opted out of the settlement, rejected objections raised by a handful of water providers in the states of New York, Washington and Texas.
