PFAS Information:

Per- and polyfluoroalkyl substances (PFAS) are a large of group contaminants which are commonly referred to as "forever chemicals". Increasing concern around the potential long term health impacts from consumption of these chemicals have motivated federal and state agencies to develop new minimum control standards for public water supplies. Foxborough water is below the current MassDEP threshold of 20 parts per trillion. However, EPA is in the process of establishing a new minimum standard of 4 parts per trillion with a target of 0 parts per trillion which will require the Town to construct additional treatment facilities for removal.

Latest Update:

The Chestnut Street Water Treatment Plant on Pumping Station Road is getting a big upgrade! The town is adding a new filtration system called Granular Activated Carbon (GAC). This system will work alongside the one already in place to better remove PFAS (a group of chemicals sometimes called “forever chemicals”). With this upgrade, we’ll be able to provide cleaner, safer drinking water for our community.

The building itself is mostly done, but crews are still hard at work inside. They need to install piping, tanks, and mechanical equipment before the plant is fully ready. The project is expected to wrap up by late spring of 2026.
