Lawyers for Wolverwine Worldwide and 3M appeared in court on Friday morning, defending themselves against dozens of Kent County residents who say they were injured by PFAS contamination.

But they're going to have to wait for a judge's decision.

The lawsuits are tied to groundwater contamination at site near U.S.-131 and Ten Mile Road, west of Rockford.

Wolverine Worldwide dumped chemical sludge at the site decades ago, and waterproofing chemicals in that sludge caused the PFAS contamination.

Both Wolverine and 3M filed several motions to dismiss the lawsuits. Their lawyers argued the plaintiffs had not produced enough evidence of physical or personal injury.

3M attorneys argued Wolverine Worldwide should be the sole defendant because company ignored manufacturer safety guidelines.

The plaintiffs' lawyer says both companies are responsible and says 3M knew contaminated water was seeping into the ground.

The judge will decide on most of the motions by the end of the December and the last one by mid-January.
