PARKERSBURG, W.Va. (AP) - Researchers want to know how long a chemical used to produce Teflon remains in the body.
The review will expand an ongoing study of mid-Ohio Valley residents on whether the chemical, referred to as C-8, is harmful to human health.
Residents in West Virginia and Ohio sued DuPont Company in 2001 charging that the company's Washington Works plant near Parkersburg had contaminated their water supplies. To settle the class-action lawsuit, the company agreed to fund a health screening for up to 70-thousand residents.
Now, a science panel charged with looking at health histories and blood samples from residents wants to expand the study to determine how long C-Eight stays in the body.
Over the next four years, up to 200 residents who receive their water from Little Hocking, Ohio, and Lubeck water systems will be paid to provide blood samples.
The two water systems were selected because both are expected to begin using carbon filters that are designed to remove C-Eight from the water.
