New Hampshire decreases allowable lead in drinking water at schools

New Hampshire Governor Chris Sununu recently signed House Bill (HB) 1421, “Lead in Drinking Water in Schools and Licensed Child Care Facilities,” which makes several changes to a 2018 law that requires New Hampshire schools and licensed child care facilities to test their drinking water for lead.

Most significantly, HB1421 decreases the allowable level of lead from 15 parts per billion (ppb) to 5 ppb.

Under the new law, schools and child care facilities must correct all locations where previous testing results showed lead levels at or above 5 ppb. Facilities have 90 days to review previous testing results and submit a remediation plan to the New Hampshire Department of Environmental Services (NHDES) for approval.
