Public hearings begin this week on the state's proposed drinking water regulations for toxic PFAS chemicals.
Regulators have devised standards for four types of PFAS. They would require all public water systems to regularly test and potentially treat for the chemicals.
If the rules are approved, New Hampshire would become one of only a handful of states with this kind of regulation. But some advocates think the state's proposals aren't strict enough to protect public health.
The state Department of Environmental Services says new research it reviewed just last month might lead it to pursue lower PFAS limits.
State legislators are also pursuing bills to require more, stricter PFAS regulation.
Residents can weigh in on the state’s current proposals at the hearings – Monday at 5:30 p.m. at Merrimack Town Hall, Tuesday at 1 p.m. in Concord at the DES auditorium, and next Tuesday at 5:30 p.m. at the DES Pease offices in Portsmouth.
Written comments can also be sent to the state’s drinking water quality manager, Chip Mackey, at email@example.com through April 12 at 4 p.m.
