Judge temporarily halts strict New Hampshire PFAS regulations

Dec 4, 2019


  • New Hampshire's regulations of per- and polyfluoroalkyl substances (PFAS) require a more thorough cost-benefit analysis before implementation, according to a new ruling. The Union-Leader reports Merrimack County Superior Court Judge Richard B. McNamara granted a preliminary injunction against required testing for PFAS​ in landfills, wastewater treatment plants, and water systems on Nov. 26.
  • Several companies, including PFAS manufacturer 3M, argued the rules constituted an unfunded mandate in a September lawsuit, which McNamara said likely did not apply. "Plaintiffs have not established that they will likely succeed [in their arguments]," he wrote, but nonetheless determined that the state Department of Environmental Services (DES) "has not conducted an adequate cost-benefit analysis" to regulate PFAS.
