Return to PFOA Class Action Suit

Return to Newspaper articles and Documents related to PFOA Class Action

C8 or C-8: PFOA is perfluorooctanoic acid and is sometimes called C8. It is a man-made chemical and does not occur naturally in the environment. The "PFOA" acronym is used to indicate not only perfluorooctanoic acid itself, but also its principal salts.
The PFOA derivative of greatest concern and most wide spread use is the ammonium salt (
Ammonium perfluorooctanoate) commonly known as C8, C-8, or APFO and the chemical of concern in the Class Action suit in Ohio.

Ammonium perfluorooctanoate (APFO or C8)
CAS No. 3825-26-1. Molecular formula:

Perfluorooctanoic acid (PFOA or C8)
CAS No: 335-67-1
. Molecular formula:

The DuPont site where APFO is used as a reaction aid is the Washington Works (Route 892, Washington, West Virginia 26181) located along the Ohio River approximately seven miles southwest of Parkersburg, West Virginia.

The Little Hocking Water Association well field is located in Ohio on the north side of the Ohio River immediately across from the Washington Works facility. Consumers of this drinking water have brought a Class Action suit against the Association and DuPont for the contamination of their drinking water with DuPont's APFO, which residents and media refer to as C8.

PFOA is used as a processing aid in the manufacture of fluoropolymers to produce hundreds of items such as non-stick surfaces on cookware (TEFLON), protective finishes on carpets (SCOTCHGUARD, STAINMASTER), clothing (GORE-TEX), and the weather-resistant barrier sheeting used on homes under the exterior siding (TYVEK).

Environmental Working Group (EWG) Statement on Opening Arguments of Teflon Chemical Trial

December 17, 2004 — Yesterday an Environmental Protection Agency administrative law judge held the first hearing in the trial of of EPA vs. DuPont for allegedly covering up information about the health effects of a toxic, indestructible chemical used to make Teflon that has turned up in over 95 percent of Americans' blood. The lawsuit began after EWG gave EPA documents showing that DuPont had failed for twenty years to provide the Agency with critical health information about its Teflon chemical. After a year-long investigation EPA filed a complaint against DuPont, finding that the company engaged in unlawful behavior on three separate counts of hiding critical study results in company file cabinets for up to 20 years.

Internal DuPont documents show that in the early 1980s scientists at the company's Parkersburg, W. Va. Teflon plant discovered startling evidence that a key Teflon ingredient had contaminated local drinking water supplies, and that babies of plant workers had a Teflon ingredient in their cord blood and were born with birth defects. DuPont failed to submit these findings to the federal government, and also failed to tell workers and the local communities of the contamination. EPA lawyers have determined that these documents were suppressed in violation of two federal laws — the nation's toxic chemical pollution law (the Toxic Substances Control Act, or TSCA), and the law governing toxic chemicals at industrial facilities, the Resource Conservation and Recovery Act (RCRA).

At the hearing, DuPont argued that it didn't have to tell EPA about the pollution connected with its highly profitable Teflon chemical, because the company was taking part in an amnesty program, the so-called Compliance Audit Program, or CAP. Provisions of the CAP program were debated, but there is one overarching point: DuPont never submitted these documents to EPA, under the amnesty program or under TSCA.

"Because DuPont did not give EPA this damaging information about their Teflon chemical under the law or under a voluntary amnesty program, they should be subject to the maximum fine of $313 million," said EWG Vice President for Research Jane Houlihan.

"DuPont would have us believe that EPA has no authority to ask chemical companies for basic health and safety information about untested chemicals that Americans are exposed to every day," continued Houlihan. "Under the public health system invented yesterday by DuPont's lawyers, EPA would be unable to protect anyone from exposures to chemicals like this toxic, persistent Teflon ingredient. Thankfully, that's not the case."
