3M Claiming Military Immunity in Minnesota PFAS Case

(Learfield News/Maplewood, MN)  —  Officials at 3M are claiming military immunity in the Minnesota PFAS case.

The Maplewood-based company claims it’s not liable for the pollution in the Mississippi River because it was the result of work being done for the military.

That comes after a six-year battle between 3M and the state of Minnesota over the forever chemicals in the river.

3M previously used the chemicals in products like Scotchgard but stopped manufacturing the chemicals in 2025.

Some PFAS have been linked with cancers, and all of them are resistant to breaking down in the environment and the bodies of humans.
