New Jersey’s attorney general said Tuesday chemical manufacturer 3M agreed to pay up $450 million to resolve lawsuits over natural resource contamination stemming from PFAS — commonly referred to as “forever chemicals.” The settlement is subject to court approval and a public comment period, Attorney General Matt Platkin’s office said. St. Paul, Minnesota-based 3M is expected to pay $285 million this year, with additional amounts payable over the next 25 years.
