3M is set to pay New Jersey up to $450 million over the next quarter-century to settle claims it contaminated the state with harmful “forever chemicals,” or PFAS, affecting drinking water.

The Minnesota-based chemicals giant manufactured the PFAS, which were used for decades at the Chambers Works facility in Deepwater, N.J., a nearly 1,500-acre complex on the banks of the Delaware River. The site was owned by DuPont, a rival company.

It is the largest single clean-water settlement in New Jersey’s history, the state said. New Jersey sued 3M, DuPont and other PFAS manufacturers in 2019, saying the facility had contaminated drinking water.

PFAS, or per- and polyfluoroalkyl substances, is used in a range of everyday products like nonstick cookware, water-repellent clothing and stain-resistant carpets. Exposure to the chemicals has been linked to metabolic disorders, decreased fertility in women and developmental delays in children, as well as increased risk of some prostate, kidney and testicular cancers.

Under the settlement announced Tuesday, 3M will pay New Jersey between $400 million to $450 million over 25 years to pay for damages, as well as cleanup and drinking water treatment.

DuPont and its chemical spinoff Chemours, which now owns the Chambers Works facility, were not part of the settlement, New Jersey said. The remaining parties are expected to proceed to trial in the case. DuPont declined to comment.
