Community Notice: MassDEP approved PFAS treatment system

By contributor,
Town Seal

The Massachusetts Department of Environmental Protection (“MassDEP”) has approved Hopkinton's activation of the full-scale PFAS treatment system at Well #6.

The system is in operation and cleaner water is flowing to users. This water treatment system is designed to remove Per- and polyfluoroalkyl substances (PFAS) to levels reliably and consistently below the current MassDEP and EPA Maximum Contaminant Levels (MCL).

On June 13, 2024, personnel from the Central Regional Office of the MassDEP conducted an activation inspection of the full-scale PFAS treatment system at Well #6. On June 27, 2024, MassDEP notified the Town of approval to activate the temporary full-scale PFAS treatment system. This approval is good until July 1, 2027 or until Hopkinton is interconnected into the Massachusetts Water Resources Authority (MWRA) water system. In the absence of an interconnection to MWRA, the temporary PFAS treatment system will need to be converted to a permanent water treatment plant which fully complies with all permits, regulations, guidelines, and policies.

The Water Department will operate the PFAS filtration system and monitor water treatment. Sampling will be conducted in accordance with regulatory requirements and sampling results will continue to be available to the public. Additional information is available on the Water Department website at:…

The bottled water rebate program will remain in effect until the Town determines that it is no longer necessary.

Special thanks to the project team - Hopkinton Water Department, Weston & Sampson, Bay State Regional Contractors, Inc., and MassDEP.
