At the end of November 2023 the Attorney General and the Governor of Ohio announced a US$110M settlement (currently pending court approval) with Du Pont De Nemours and Co. and The Chemours Company in response to a complaint alleging that during the course of six decades, Dupont continued to release vast quantities of perfluorooctanoic acid, known as PFOA or C8, in the groundwater, drinking water, soil, and air surrounding its plant even after it knew that PFOA was toxic to humans and the environment.
