from ap.org: Nine Ohio and West Virginia residents who have cancer and other diseases have filed federal lawsuits this month against chemical giant DuPont, alleging the company knowingly contaminated drinking-water supplies with a chemical used by one of its plants. The lawsuits, filed Oct. 8 and this week, are among about 50 such cases — including one alleging wrongful death — filed against DuPont since April, when a court-appointed science panel found probable links between exposure to perfluorooctanoic acid, also known as C8, and kidney cancer, testicular cancer and thyroid disease, among others.
