| The U.S. Agency for Toxic Substances and Disease Registry is urging West Virginia officials to advise pregnant women, women of childbearing age, children and the elderly who live near DuPont's Washington Works plant to reduce their consumption of C8-polluted water.
The warning particularly affects the mixing of baby formula.
DuPont has been using C8 to produce Teflon at its plant since the 1950s.
The chemical is not federally regulated, studies have shown C8 can have adverse health effects in laboratory animals.
The West Virginia Office of Environmental Health Services chief Barbara Taylor said the Department of Health and Human Resources will be issuing public health directions for Ohio Valley residents.
