WISCONSIN — The Environmental Protection Agency (EPA) on Wednesday released new federal standards for levels of PFAS, or "forever chemicals," that can be allowed in drinking water.

"The testing can be every quarter, every calendar quarter," said Steve Elmore, program director for the Wisconsin Department of Natural Resources (DNR) bureau of drinking water and groundwater. "If they haven't been detected in the past, they could be tested every three years."

Beyond private wells, Elmore said there are nearly 2,000 public regulated systems providing water to communities across Wisconsin, and roughly 95% of them clear this new federal PFAS standard.

"What we found is that all but 89 of them meet this standard so they have PFAS levels below this new standard," Elmore said. "It's good that we know that know and we'll be working with those 89 systems to lower the levels of PFAS in their drinking water."
