EPA reports that says C8 likely carcinogenic to humans
In a draft report released Monday, the majority of the members on an EPA scientific advisory board concluded that C8, ammonium perfluorooctanoate, a byproduct of the manufacture of Dupont Teflon, is likely to be carcinogenic to humans, and that the EPA should conduct cancer risk assessments for a variety of tumors found in mice and rats after they were exposed to the chemical.
The residents with the highest concentrations of the chemical in their water are the customers of the Little Hocking Water Association, which serves most of western Washington County, Ohio.
Little Hocking Water Association General Manager Bob Griffin said, "the report is not definitive, just saying the EPA needs to take a harder look. It just reinforces our position that this chemical and any related chemicals do not belong in our water system."
A 2001 class-action suit filed in West Virginia alleged DuPont knowingly allowed C8, during the production of Teflon, to be discharged into local water supplies from its Washington Works plant. That case was settled earlier this year for $107 million.
In addition to the lawsuit, last July, the U.S. EPA determined DuPont failed, for more than 20 years, to report information as required concerning information the company had learned about C8.
Of course, DuPont officials declined to comment on the report, as reported in the Marietta Times.
