Chemical giant DuPont (DD.N) Monday will face the first trial in litigation from residents near one of its plants in West Virginia who have accused the company of sickening them by emitting a toxic chemical that leaked into their drinking water. Carla Marie Bartlett is among the approximately 3,500 plaintiffs who have sued DuPont in federal court in Ohio, saying they contracted one of six diseases linked to perfluorooctanoic acid, known as PFOA or C-8. Bartlett said she developed kidney cancer from contaminated water.
