Public invited to comment on the

Saint-Gobain PFAS report

ATLANTA, GA - The Agency for Toxic Substances and Disease Registry (ATSDR) has released a health consultation report, “Evaluation of Per- and Polyfluoroalkyl Substances (PFAS) in Private Wells near the Saint-Gobain Site in Southern New Hampshire, Merrimack, New Hampshire”, for public comment. ATSDR will accept comments from the public until March 1, 2022.

This health consultation evaluated the public health effects of exposure to per- and polyfluoroalkyl substances (PFAS) in private drinking water wells near the Saint-Gobain Performance Plastics facility in Merrimack, New Hampshire. Perfluorooctanoic acid (PFOA) was the most frequently detected PFAS in private wells in the towns of Merrimack, Litchfield, Londonderry, Bedford, and Manchester surrounding the Saint-Gobain facility. The report concluded that before actions began in 2016 to reduce exposures, drinking private well water contaminated with PFAS could have increased the risk for harmful health effects for some community members. ATSDR is preparing a separate report evaluating exposures from public water supplied in the area.

Currently, harmful exposures to PFAS in private wells have been minimized by providing alternate water and taking other actions. People who continue to drink contaminated, untreated private well water may still have an increased risk for harmful health effects. Residents continuing to drink from private wells should monitor their well water quality and should work with local authorities and the New Hampshire Department of Environmental Services to take appropriate action to remove harmful contaminants, if needed.

The public comment process gives the community an opportunity to review the report and provide input. ATSDR’s responses to those comments will be included in an appendix of the final report.
