The state holds a public hearing tonight about a new air emissions permit for the Saint-Gobain plastics factory in Merrimack. The facility is being held responsible for contaminating nearby drinking water with PFAS chemicals from its smokestacks.
The proposed air permit would dictate pollution controls for those stacks to prevent more chemicals from settling into soil and groundwater.
After the public hearing on the permit, regulators will give an update on the overall drinking water situation around the factory.
Saint-Gobain recently said it would work to set up a community group on the issue, which would give residents more say about the response.
The back-to-back meetings start at 6 p.m. tonight at James Mastricola Upper Elementary School in Merrimack.
