In January, the Columbus Dispatch reported C-8 may have contaminated water up to 230 miles downstream from DuPont's Washington Works plant -- much further than previously believed.

Cities and towns from Parkersburg, West Virginia to Pomeroy, Ohio use water filters to protect residents. But communities south of Parkersburg are not testing the water for C-8 and -- more importantly -- have no C-8 filters in place.

These communities are in danger of C-8 contamination. Water flows downstream, likely carrying C-8 contamination down the Ohio River to Cincinnati and beyond.

We deserve to know if our water is safe. Tell your representatives to test the water in your community NOW.
