Early results of a new study show landfill runoff contained the highest levels of PFAS among liquid wastes sampled statewide in Wisconsin.
Since 2023, researchers at the University of Wisconsin-Madison have been collecting and analyzing samples from four waste materials that could be potential sources of PFAS in groundwater, which provides drinking water to two-thirds of state residents. It’s also a source of drinking water for around 800,000 private wells.
