The tentative national class-action settlement in a landmark environmental fight involving PFAS chemicals in firefighting foam was reached Thursday. 3M will pay between $10.5 billion and $12.5 billion, and the settlement will cover public water systems across the U.S., plaintiffs’ attorneys said.

If completed, it would be among other major settlements involving litigation over products deemed to be health risks, including the massive agreements reached in lawsuits involving tobacco, opioids and asbestos.
