On 30 August 2001, approximately 80,000 people living in West Virginia and Ohio states filed a class-action lawsuit, alleging that DuPont’s Washington Works Plant in Washington, West Virginia, had contaminated the local water supplies with perfluorooctanoic acid, or PFOA, in Jack W. Leach, et al. v. E.I. du Pont de Nemours & Company (2005), hereafter Leach v. du Pont. PFOA is a human-made chemical, part of the PFAS family, more commonly called forever chemicals. PFOA plays a fundamental role in the production of materials like Teflon and nonstick and stain-resistant consumer products. The plaintiffs of the case alleged that DuPont failed to contain or warn the residents about the dangers of PFOA, which can include hormone disruptions, cancers, and pregnancy complications. The case led to a settlement in 2005 in which DuPont agreed to pay 70 million US dollars in class benefits, and also prompted changes in policy designed to protect individuals and communities from the dangers of PFOA and other forever chemicals.
