relative to per and polyfluoroalkyl substances (PFAS) and public health data.

HB 1258 requires New Hampshire's Department of Environmental Services to publish PFAS testing results on its public website. The bill mandates the department to include data from public water systems, private wells tested through state programs, and environmental samples like soil, water, and fish tissue. Published data must be searchable by location, date, and contaminant type, with updates every six months while protecting private well owners' personal information. This law directly affects public access to PFAS contamination data and the department's reporting obligations.
