"Study: Toxic PFAS Chemical Plume Detected in Green Bay"

"A large plume of toxic chemicals produced by a plant that manufactures firefighting foam has seeped through groundwater to Lake Michigan’s Green Bay, scientists said Tuesday.

The chemicals belong to a family of compounds known as PFAS, or per- and polyfluoroalkyl substances, which are used widely in consumer products ranging from nonstick cookware and water-repellent sports gear to stain-resistent carpets. They’re also a key ingredient in fire-extinguishing foams. They can accumulate and persist in the human body for long periods, and exposure may lead to cancer and other health problems.

Groundwater and streams near the Tyco Fire Products in Marinette, Wisconsin, are contaminated with foam from the plant’s testing facility.

University of Wisconsin researchers have traced movement of the chemicals in nearby groundwater and streams. In a report published last week, they said a plume had made its way into Green Bay, which extends 120 miles (193 kilometers) along northeastern Wisconsin and the south coast of Michigan’s Upper Peninsula."
