PFAS: Explained

The State of Michigan is finding industrial chemicals known as PFAS in the tissue of fish. So it's been issuing “Don’t Eat the Fish” advisories along lakes, rivers and streams. But there are concerns about whether state officials are doing as much as they should. 

Before we get too far into the story, we have to start with a little science.

The reason PFAS chemical contamination in fish is such a concern is because of something called bioaccumulation.

PFAS contamination has been known to be a problem. What's different is we’re discovering the problem is bigger than imagined.

In recent months, the State of Michigan has found several places where drinking water and fish are contaminated by a class of chemicals called PFAS. This pollution is coming from a variety of sources.
