Wisconsin Sea Grant-supported research finds Great Lakes tributary rivers play important role in bringing PFAS to the drinking water source of millions
The world’s largest source of fresh water, the Great Lakes, provides drinking water to more than 40 million people in the U.S. and Canada. In the first study of its kind, researchers at the University of Wisconsin-Madison College of Engineering, funded by Wisconsin Sea Grant, have demonstrated that tributary rivers feeding Lake Michigan play an important role in bringing the human-made group of chemicals known as per- and polyfluoroalkyl substances (PFAS) to the Great Lakes system.
