The St. Clair River is on a list of toxic hot spots in Michigan. They’re called Areas of Concern.

The river is on this list because of a long history of industrial pollution. But people have been working to clean it up.

In order to take the river off the list, there are a number of problems that have to be fixed.

One of these is beach closings. Those can happen when untreated sewage gets into the river during storms. But officials say things are getting much better on that front.

There are 12 toxic hot spots in Michigan called Areas of Concern.

These are places in the Great Lakes basin where pollution and development have damaged the ecosystems.

The Detroit River is on this list. Before the Clean Water Act, industries on the river treated it as a dumping ground – think waste in the billions of gallons.

They're known as "Areas of Concern" and Michigan had 14 of them at one time.

Now, we have 12 of these toxic places where pollution from the past is lingering.

This summer, work crews will tackle the next phase of cleanup in the Muskegon Lake area.
