One of four wells in Westfield, Massachusetts, contaminated by PFAS chemicals is now pumping water in which the chemicals cannot be detected, city officials said.
The wells were contaminated by firefighting foam used at nearby Barnes Airport.
Westfield Mayor Brian Sullivan said Monday one well has a special filtration system and has, so far, pumped nearly 70 million gallons of drinkable water.
“We’re delivering clean drinking water to the north side, we will continue to monitor this, test for this until it’s gone,” Sullivan said. “That might be a very long time, but the product that comes out will be clean.”
Sullivan also said a federal lawsuit the city filed against the foam's manufacturers is still underway.
“We have two professional law firms working on this for us that are actually representing cities and towns across the nation,” he said. “Those are moving forward, not as fast as I would like to, but (are) going through the process as we speak.
Officials are holding a public meeting in Westfield on Tuesday to talk about PFAS exposure risks.
