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 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, or PFAS, to the Great Lakes system.
Christy Remucal, UW–Madison professor of civil and environmental engineering, and co-author Sarah Balgooyen, a postdoctoral researcher, quantified 10 PFAS chemicals known as perfluoroalkyl acids, or PFAAs, in the water and sediment of 41 tributaries to Green Bay of Lake Michigan. They published their findings recently in the ACS ES&T Water Journal).
