C8 AND THE FOREVER CHEMICALS

THE CLAIM

That DuPont knew for decades that perfluorooctanoic acid was accumulating in human blood and causing harm, concealed its own studies from regulators and the public, and continued discharging it into water supplies.

THE THEORY, AS ITS PROPONENTS TELL IT

The evidence in this file is almost entirely the company's own paperwork, obtained through discovery, which is why the claim needs no advocacy.

DuPont began using C8 at its Washington Works plant in 1951. Internal studies found the compound in workers' blood by 1976. In 1981 the company recorded birth defects among children of women working in the Teflon division and moved those women out of the area. It did not report this to the Environmental Protection Agency.

The compound was discharged into the Ohio River and into unlined landfills, and reached the drinking water of tens of thousands of people. DuPont's own sampling recorded levels in local water above its own internal safety guideline, and the company did not tell the water districts.

The case broke because one lawyer, Robert Bilott, took a farmer's cattle case in 1999 and filed a discovery request broad enough to reach the company's internal files. The result was roughly 110,000 pages. A 2004 class settlement funded an independent science panel, which tested nearly 69,000 people and found probable links between C8 and kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, preeclampsia and high cholesterol.

WHAT IS KNOWN

The internal documents are real and were entered in litigation. DuPont paid a $16.5 million EPA penalty in 2005 for failing to disclose information about C8, at the time the largest civil administrative penalty the agency had obtained.

The C8 Science Panel was independent, funded under the settlement, and its findings are published. It is one of the largest human health studies ever conducted on a single compound.

DuPont and its spinoff Chemours settled thousands of personal injury claims for hundreds of millions of dollars, and further multi-state settlements followed over PFAS contamination generally.

PFAS compounds are now detectable in the blood of most people tested worldwide, and in rainwater globally. The class is called forever chemicals because the carbon-fluorine bond does not meaningfully degrade in the environment.

EVIDENCE FOR

• DuPont's own internal studies, dated and entered into evidence, showing blood accumulation from 1976 and reproductive harm reported in 1981.
• The EPA penalty for failure to disclose, which is an official finding of concealment.
• The C8 Science Panel's findings, based on testing nearly 69,000 people, published and independent.
• Settlements of thousands of individual claims, which the company would not have paid on speculative evidence.

EVIDENCE AGAINST (THE STRONGEST READING)

• The science panel found probable links for six conditions and explicitly did not find links for many others, and the popular version of this file often ignores that.
• Regulatory standards for C8 did not exist for much of the period, so a great deal of the discharge was legal at the time, which is an indictment of the regime rather than a defence of the company.
• Attributing any individual illness to C8 remains difficult, which is why the litigation used probabilistic findings rather than case-by-case causation.

ASSESSMENT

Confirmed, and the most recent entry in the pattern this cabinet keeps documenting. The shape is identical to OSA-017, OSA-062 and OSA-106: an industry generates the knowledge internally, keeps it, and continues, and the accounting arrives decades later through litigation rather than regulation. What makes this one distinctive is scale and permanence. The tobacco documents describe a harm that stops when people stop smoking. This one is in the blood of nearly everyone reading this, and in rainwater, and it does not break down.

WHAT WOULD CHANGE THE GRADE

• CONFIRMED from the company's own studies, entered in litigation: the compound in workers' blood by 1976, birth defects reported among employees' children in 1981, and a $16.5 million EPA penalty for failing to disclose.
• The health findings are specific rather than general. The C8 Science Panel, having tested nearly 69,000 people, found probable links to six conditions and explicitly did not find links to many others.
• Still open: the full extent of contamination and of liability. PFAS compounds are now detectable in most people tested worldwide and in rainwater, and the litigation continues.
