Toxic "Forever Chemicals" Spark Widespread Health Concerns and a Patchwork of State Bans

The city of Stuart, Florida is suing 3M over water contamination from toxic firefighting foam chemicals that have been found in nearly every American's blood.
The trial, set to begin this week, is a test case that could determine 3M's liability for pollution from PFAS chemicals linked to various health issues.
At least 24 states have enacted bans or limits on PFAS chemicals, fed up with decades of federal inaction despite known risks going back to 2001.
The companies that made and used PFAS chemicals deny that most are harmful but face a snowballing number of lawsuits as the chemicals turn up in waterways nationwide.
Some Republican-led states have joined bipartisan efforts to regulate the chemicals, highlighting growing concerns over their effects on public health.
