SPRINGFIELD, Mo. — City Utilities (CU) of Springfield is accusing the technology company 3M of water pollution. The lawsuit, which CU filed this week, claimed 3M has released ‘forever chemicals’ that are making their way into the James River. CU treats the water from James River so residents can use it as drinking water. “I have known for years that that that there’s been pollution in [the water], especially in the James,” Springfield resident Jimmy Spinner said.
