Saint-Gobain Performance Plastics in Merrimack (copy)

Saint-Gobain Performance Plastics in Merrimack has agreed to provide safe drinking water to more than 1,000 properties in five towns, including Bedford.

The Merrimack Village District water utility is suing French manufacturing giant Saint-Gobain and two local manufacturers over groundwater polluted with “forever chemicals,” which the water utility alleges was a result of the companies’ manufacturing practices even after they knew the chemicals were harmful.

The Merrimack Village District’s suit was filed last week in Hillsborough County Superior Court, according to a news release from the utility. The suit names Saint-Gobain Performance Plastics as a defendant, along with Textiles Coated International of Londonderry and DiaCom Corporation of Amherst.
