Chemical manufacturer 3M will pay up to $7.35 billion to settle lawsuits by people who say they were sickened by groundwater contamination

Chemical manufacturer 3M will pay up to $7.35 billion to settle lawsuits by people who say they were sickened by groundwater contamination from compounds used in firefighting foam and other consumer products. The St. Paul, Minnesota-based company announced the settlement Tuesday. It will pay the money over nine years to as many as 120,000 people who say they were harmed by exposure to per- and polyfluoroalkyl substances, known collectively as PFAS. The chemicals contaminated groundwater near military bases, airports and other locations where the foam was used to extinguish fires.
