The DuPont C8 settlement is not one deal but a chain of them, resolving claims that DuPont contaminated drinking water with perfluorooctanoic acid (PFOA), the chemical the company internally called C8. The largest pieces are a 2005 West Virginia class action worth up to $405 million that funded a landmark health study, a 2017 global settlement of $670.7 million resolving about 3,500 personal injury lawsuits tied to six diseases, and a 2023 settlement of $1.185 billion with public water systems across the country. State settlements with Ohio ($110 million) and New Jersey (up to $875 million) have since added to the total, and a medical monitoring program remains open to eligible residents.
What C8 Is and How It Got Into the Water
DuPont opened its Washington Works plant near Parkersburg, West Virginia, in 1948 and began using PFOA to manufacture Teflon in 1951.1PFAS Project. Parkersburg West Virginia Over the following decades, the chemical entered the environment through air emissions, unlined waste pits that leached into groundwater, and runoff into creeks feeding the Ohio River.2EPA. Chemours Washington Works History and Safe Drinking Water Act Settlements By 1984, DuPont’s own monitoring confirmed C8 in the public water supplies of Lubeck, West Virginia, and Little Hocking, Ohio.3HuffPost Highline. Welcome to Beautiful Parkersburg
Internal records later showed employees had flagged possible toxicity as early as 1954, that a 1981 study of 50 female workers found a statistically significant increase in birth defects among the exposed, and that 1982 memos noted C8 accumulates in the human body.3HuffPost Highline. Welcome to Beautiful Parkersburg The company continued discharging the chemical and did not disclose the findings to regulators for years.
The 2005 Class Action Settlement
The core class action, Jack W. Leach, et al. v. E.I. du Pont de Nemours & Co. (No. 01-C-608), was filed in August 2001 in the Circuit Court of Wood County, West Virginia. It represented roughly 80,000 people in six water districts across West Virginia and Ohio whose drinking water had been contaminated by C8 from Washington Works.4Business & Human Rights Resource Centre. DuPont Case
A West Virginia court approved the settlement in early 2005. Its initial payment component was $107.6 million,5Chemical & Engineering News. DuPont Settles PFOA Case but DuPont’s total commitment reached $405 million, including $335 million for the settlement itself and $70 million for a health and education project.4Business & Human Rights Resource Centre. DuPont Case The agreement had four moving parts:
- Water treatment: DuPont installed filtration in the contaminated districts, spending more than $20 million on the equipment.6Hill, Peterson, Carper, Bee & Deitzler. C8 Class Action Settlement
- An independent science panel of three epidemiologists, funded with more than $30 million, to determine whether C8 exposure was linked to human disease.6Hill, Peterson, Carper, Bee & Deitzler. C8 Class Action Settlement
- Up to $235 million for medical monitoring and screening if the panel found a probable link to any disease.5Chemical & Engineering News. DuPont Settles PFOA Case
- Preserved personal injury rights: class members could not sue for personal injury until the panel finished, but DuPont was not shielded from suits once a probable link was found.4Business & Human Rights Resource Centre. DuPont Case
One provision proved decisive. DuPont agreed to accept “general causation” for any disease the panel linked to C8, meaning the company could not later argue in personal injury lawsuits that the science tying C8 to those diseases was insufficient.7U.S. District Court, Southern District of Ohio.

The Six Diseases Linked to C8
The C8 Science Panel — epidemiologists Tony Fletcher, David Savitz, and Kyle Steenland — was chosen jointly by the plaintiffs and DuPont.8C8 Science Panel. C8 Science Panel Its companion C8 Health Project enrolled roughly 69,000 participants from the affected water districts between 2005 and 2006 and collected blood samples, health surveys, and medical records.9National Institutes of Health. C8 Health Project
Between 2011 and 2012, the panel concluded a “probable link” existed between PFOA exposure and six conditions:8C8 Science Panel. C8 Science Panel
- Kidney cancer
- Testicular cancer
- Thyroid disease
- Ulcerative colitis
- Diagnosed high cholesterol
- Pregnancy-induced hypertension, including preeclampsia
Those six diseases became the eligibility gate for the personal injury lawsuits that followed. The panel completed its work in 2013 and no longer exists.8C8 Science Panel. C8 Science Panel
Medical Monitoring for Eligible Class Members
The medical monitoring program established under the 2005 settlement remains active. It offers free screening for the six linked conditions to eligible class members, though participation has been low relative to the roughly 80,000 people who qualify.10C-8 Medical Monitoring Program. C-8 Medical Monitoring Program If you lived in one of the six affected water districts during the relevant exposure period, you may still be eligible.
The 2017 Personal Injury Settlement: $670.7 Million
With the science panel’s findings in hand, roughly 3,500 personal injury lawsuits were filed and consolidated into a multidistrict litigation in the U.S. District Court for the Southern District of Ohio. The court picked bellwether cases to test the claims.
Three Bellwether Verdicts
All three went for the plaintiffs, and the punitive damages climbed sharply from case to case:
- Carla Bartlett (October 2015), kidney cancer: $1.6 million total, with $1.1 million for negligence and $500,000 for emotional distress.11Hill, Peterson, Carper, Bee & Deitzler. DuPont C8
- David Freeman (July 2016), testicular cancer: $5.1 million compensatory and $500,000 punitive, totaling $5.6 million, with the jury finding DuPont’s conduct malicious.11Hill, Peterson, Carper, Bee & Deitzler. DuPont C8
- Kenneth Vigneron (December 2016 to January 2017), testicular cancer: $2 million compensatory and $10.5 million punitive, totaling $12.5 million.11Hill, Peterson, Carper, Bee & Deitzler. DuPont C8
The Global Settlement
In February 2017, after three straight losses at trial, DuPont and its corporate successor Chemours agreed to a $670.7 million settlement, split evenly at $335.35 million each.12Chemours.

The 2023 Water Utility Settlement: $1.185 Billion
On June 2, 2023, DuPont, Chemours, and Corteva announced a $1.185 billion settlement to resolve PFAS drinking water claims brought by public water systems nationwide.17Corteva. Chemours DuPont and Corteva Reach Comprehensive PFAS Settlement With US Water Systems The deal is part of MDL 2873 (In re: Aqueous Film-Forming Foams Products Liability Litigation), centralized in the U.S. District Court for the District of South Carolina before Judge Richard M.

State Settlements: Ohio and New Jersey
Ohio: $110 Million
On November 29, 2023, Governor Mike DeWine and Attorney General Dave Yost announced a $110 million settlement with DuPont, Chemours, and Corteva over contamination from Washington Works. The money goes into an environmental restoration fund: 80% for pollution from the plant, 16% for firefighting foam damages, and 4% for natural resource mitigation.21Governor of Ohio. State Secures $110 Million Settlement With DuPont for Environmental Restoration Along Ohio River Ohio alleged the facility released PFOA into the air and the Ohio River from the 1950s through 2013, and Yost said the payment would be a lump sum issued within 10 days.22Ohio Capital Journal.

New Jersey: Up to $875 Million
On August 4, 2025, the three companies reached a proposed settlement with the New Jersey Department of Environmental Protection valued at up to $875 million over 25 years, with a pre-tax present value of about $500 million.23DuPont. Chemours DuPont and Corteva Reach Agreement With the State of New Jersey It resolves claims at four current and former manufacturing sites — Chambers Works, Parlin, Pompton Lakes, and Repauno — and includes $225 million for natural resource damages, $525 million for environmental cleanup, and approximately $125 million in costs, penalties, and punitive damages.24New Jersey DEP. DuPont Costs are split among Chemours (50%), DuPont (35.5%), and Corteva (14.5%).
The companies must also continue cleanup at all four sites, transfer 73 acres near Ramapo State Forest to the state, and place conservation easements on nearly 1,400 additional acres. A reserve fund of up to $475 million, backed by surety bonds, secures the remediation obligations. The agreement was published for public comment in September 2025 and needs final court approval, with the earliest entry date set for January 1, 2026.24New Jersey DEP. DuPont
Who Actually Pays: DuPont, Chemours, and Corteva
The settlements name three companies because DuPont’s fluorochemicals business was spun off as The Chemours Company in 2015, and DuPont later split again during a 2017 merger with Dow and the 2019 reorganization of DowDuPont, producing Corteva.25Chemours. Chemours Amended Complaint Under a binding Memorandum of Understanding signed on January 22, 2021, the three agreed to share legacy PFAS costs on a 50-50 basis, with Chemours covering half and DuPont and Corteva together covering the other half. The arrangement is capped at $4 billion in qualified spending and runs through the end of 2040. Between DuPont and Corteva, costs up to $300 million are split equally; beyond that, DuPont bears 71% and Corteva bears 29%.26U.S. SEC. MOU Between DuPont, Corteva, and Chemours That is why announcements about “DuPont” settlements now typically list all three payers.
The Broader PFAS Litigation Still Underway
The C8 cases opened the door to a wave of PFAS lawsuits that reaches well beyond Parkersburg. MDL 2873 in South Carolina has grown to more than 10,000 associated cases involving tens of thousands of plaintiffs, covering personal injury, property damage, and medical monitoring claims tied to PFAS in firefighting foams and other products.27U.S. District Court, District of South Carolina. MDL 2873 In 2024, the EPA finalized maximum contaminant levels for six PFAS compounds in drinking water. Litigation over those standards continues, and in January 2026 a federal appeals court rejected a request from the Trump administration to vacate the rules for four of the compounds.19National League of Cities. PFAS Settlement Deadlines Updated
For residents of the original six water districts, the practical takeaway is that the 2017 personal injury settlement closed the door on the pending cases at that time, but the medical monitoring program from the 2005 class action continues to offer free screening for the six linked diseases. For public water systems, the 2023 settlement’s Phase 2 claim windows are still open through mid-2026. And for anyone tracking the money: the 2023 utility settlement alone is larger than every prior DuPont C8 settlement combined, and the New Jersey deal, if approved, will add substantially more.
