After two years of work, the Wisconsin Department of Natural Resources is nearing completion of the first regulations designed to limit the amount of toxic “forever chemicals” in drinking and surface water.

Under the direction of Gov. Tony Evers, the DNR is working to add some fluorinated compounds, collectively known as PFAS, to a list of regulated contaminants in drinking water, groundwater and surface water.

The DNR will hold a public hearing on Wednesday on the first of two proposed drinking water regulations, which target two of those chemicals, PFOA and PFOS. A second hearing is scheduled for Dec. 10 on surface water regulations.
