EPA to fine DuPont over ingredient in Teflon

10:00am, July 28, 2004

The Environmental Protection Agency says it may levy a fine surpassing $300 million against the Wilmington, Del.–based chemical giant DuPont. The government accuses the company of concealing for 2 decades that it was contaminating the environment with perfluorooctanoic acid (PFOA) and putting at risk the health of workers. DuPont uses the synthetic chemical in the manufacture of many stain-resistant and nonstick substances, including some Teflon coatings.

PFOA, which research has shown can produce cancer and birth defects in animals, is present in nearly everyone's blood, but only in small amounts. EPA isn't seeking to ban the chemical, but the agency considers the health of people who work with it to be at risk.

In 1981, DuPont scientists discovered PFOA in the blood of some company workers in concentrations that should have prompted notification of federal officials, EPA says. Soon afterward, DuPont detected the chemical in public water supplies near its plants.
