How do PFAS end up in drinking water?
Drinking water contamination can come from a number of different sources:
-
discharges from manufacturing facilities that use PFAS
-
discharges from wastewater treatment plants
-
water that percolates down through the soil around landfills
-
firefighting foams that run off into surface waters
The Wisconsin Department of Natural Resources (DNR) maintains a of sites in Wisconsin with potential and confirmed PFAS contamination in soil and groundwater. Click here to open the interactive map.
