St Paul, MN (KROC AM News) - The Army Corps of Engineers says don’t worry about the areas of foam spotted in the Mississippi River near Wabasha.

The Corps says dredging activities in the area are creating the foam near the Crats Island unloading site.

The Corps says the naturally occurring foam -  sometimes in the form of thin white lines or grey-brown floating clumps -  is created by the mixing of plant materials and water during the dredging process. The foam can also develop on windy and wavy days.

The Corps says the foam is not known to be harmful to people, pets or the ecosystem. It will eventually break down and disappear.

The Crats Island dredging project involves removing 900,000 cubic yards of material from the temporary placement site.

 

The project is scheduled to be completed by the end of 2017.
