NATICK, MA — Natick Town Meeting will soon take up a proposal to spend $3 million to reduce PFAS contamination at one of the town's main water treatment plants.
Earlier this year, Natick discovered levels of PFAS chemicals were above the state minimum threshold at the Springvale H&T treatment facility. The state maximum threshold is 20 parts per trillion (ppt), but the levels at two locations at Springvale have measured 24 ppt and 21 ppt on average in recent months.
Under state law, communities that detect elevated PFAS levels must work on long and short-term fixes for the problem. For now, Natick has reduced its reliance on Springvale for drinking water. For the long-term fix, Natick would spend $3 million to install carbon filters at Springvale to remove PFAS, and to build a new structure to house the filters.
