U.S. District Court Judge Renee Marie Bumb ruled October 9 that people residing on property near the Dupont Chambers Works facility in Deepwater, New Jersey, are eligible to pursue a class action lawsuit against the company. The suit alleges Dupont has contaminated  area drinking water wells and the local public water supply system with a toxic chemical called PFOA (or C8), ammonium pefluorooctanoate.
