Perfluorooctanoic acid—PFOA, plant shorthand “C8”—was a processing aid in fluoropolymer manufacture at DuPont’s Washington Works along the Ohio River in West Virginia. Workers and neighbors later learned the compound was in blood, water, and waste streams while substantial-risk reporting duties under federal toxics law were the subject of EPA enforcement. The Archive tension is not that PFOA existed. It is the cover-trail gap: what DuPont knew, when EPA learned it through TSCA and RCRA channels, and how consent agreements, stewardship phase-outs, and later Chemours successor settlements turned private risk knowledge into public penalty paper.
Washington Works, Not a Folklore Plant
Washington Works at Washington, Wood County, West Virginia, produced Teflon-related fluoropolymers using PFOA. Mid-Ohio Valley communities drew drinking water from sources later tested for C8. A West Virginia class action (Leach) produced a court-supervised C8 Science Panel that assessed probable links between PFOA exposure and specific human diseases. That panel’s probable-link findings are epidemiology under a settlement protocol—not a criminal verdict—but they sit in the public record beside EPA’s administrative case. Caption-ready frames: the river plant, community wells, blood-serum sampling language in agency complaints.

Official Posture: TSCA 8(e), Penalties, Stewardship
In 2004–2005 EPA filed administrative complaints alleging DuPont failed to submit substantial-risk information about PFOA under Toxic Substances Control Act section 8(e) and failed to submit certain data under RCRA authorities. On 14 December 2005 EPA announced a Consent Agreement and Final Order resolving those counts—then billed as the largest civil administrative penalty in Agency history under the environmental statutes at issue: $10.25 million in civil penalties plus $6.25 million in Supplemental Environmental Projects. The CAFO docket numbers (TSCA-HQ-2004-0016, RCRA-HQ-2004-0016, TSCA-HQ-2005-5001) are the enforcement spine.

EPA’s archived 14 December 2005 news release states the violations included failures to report substantial-risk information DuPont obtained from as early as 1981 through 2004—human health information, environmental contamination, and animal toxicity studies among the count categories. That is Agency charging language, not a documentary film script. Read it as the official “what should have been reported when” hinge.

Stewardship, Spinoff, Successor Paper
EPA’s 2010/2015 PFOA Stewardship Program pushed major manufacturers toward elimination of PFOA emissions and product content on a public commitment schedule. DuPont’s participation letters and EPA’s fact sheet are the phase-out optics door. In 2015 DuPont spun The Chemours Company as the fluoroproducts successor operating Washington Works and related lines. Later EPA and DOJ actions against Chemours for PFAS releases in multiple states—including a 2020s landmark multi-hundred-million-dollar settlement package—extend the cover-trail into successor liability and Clean Water Act / toxics enforcement beyond the 2005 CAFO alone.

Class-Action Science Beside EPA’s Desk
The Leach v. E.I. du Pont West Virginia settlement did something unusual in toxics litigation: it funded an independent C8 Science Panel to determine whether probable links existed between PFOA exposure and human disease in the Mid-Ohio Valley class. Probable-link findings for kidney cancer, testicular cancer, ulcerative colitis, thyroid disease, hypercholesterolemia, and pregnancy-induced hypertension entered the public record through that panel’s protocol. Those findings are not EPA’s 2005 CAFO counts, and the CAFO is not the panel. Adherents sometimes mash them into one “cover-up proof.” Keep them adjacent: court-supervised epidemiology on one track; TSCA section 8(e) reporting failures on the other. Together they explain why Washington Works became the national C8 teaching case without requiring a single fused conspiracy caption.
Why “Cover Trail” Is the Right Tension
Internal sampling, worker-blood data, and community serum results that EPA later said should have been submitted under TSCA 8(e) are the documentary heart. The 2005 settlement does not prove a cartoon of “they invented forever chemicals in secret.” Fluoropolymers were commercial products; PFOA’s hazard profile sharpened over decades. The adherent-readable so-what is reporting asymmetry: risk information in company files versus what reached EPA’s substantial-risk desk before complaints and the CAFO. Court-supervised science-panel probable links and later drinking-water actions sit beside that enforcement hinge without requiring mythic embellishment.
Myth Discipline
Reject slogans that erase lawful industrial production history or invent mass-grave cover-ups the EPA CAFO does not allege. Reject merging every later PFAS site nationwide into the Washington Works 2005 docket without a citation. Stick to EPA complaint/CAFO language, Stewardship commitments, C8 Science Panel probable-link text, and successor Chemours settlement announcements for figures and counts. Prefer Agency dollar figures ($10.25M / $6.25M SEP; later Chemours package totals as EPA states them) over rounded cable numbers.
What the Paper Trail Settles
Settled on the documents: PFOA/C8 use at Washington Works; EPA TSCA/RCRA administrative complaints and the December 2005 CAFO with then-record administrative penalties; EPA statements that substantial-risk information dating back years was not timely submitted; PFOA Stewardship phase-out commitments; C8 Science Panel probable-link findings under the Leach protocol; Chemours successor PFAS enforcement/settlement paper. Overclaim to refuse: treating the 2005 CAFO as a criminal conviction, or asserting a settled “U.S. government hid C8” verdict when the spine is industry reporting failure prosecuted by EPA.
The tension that remains is the cover trail the dockets name. Officials eventually extracted penalties, SEPs, stewardship exits, and successor decrees. The same record shows years of risk information that EPA said should have been on its desk sooner. DuPont C8 is that lag—read with the CAFO and the Stewardship fact sheet open.
