Chemours Lawsuit: PFAS Settlements, GenX Order, and Active Cases

The Chemours lawsuit landscape is not a single case but a decade-long web of PFAS “forever chemicals” litigation inherited from DuPont, including a $1.185 billion national settlement with U.S. public water systems, a $2 billion agreement with New Jersey, and still-active cases brought by North Carolina utilities, residents, and the state attorney general. Chemours, spun off from DuPont in 2015, assumed roughly two-thirds of DuPont’s environmental liabilities at the time of separation, and its share of PFAS costs is now governed by a 2021 cost-sharing agreement with DuPont and Corteva.¹

Why Chemours Is the Defendant Instead of DuPont

Chemours began trading as an independent public company in July 2015 after DuPont spun off its Performance Chemicals division. Under the separation, Chemours took on about two-thirds of DuPont’s environmental liabilities across 80 sites and 90% of DuPont’s pending litigation by volume, while inheriting only about 19% of the business.¹ Chemours also paid DuPont a $3.91 billion dividend at separation, funded by $4 billion in new debt, and agreed to fully indemnify DuPont for those transferred matters.

The structure has been challenged repeatedly. North Carolina’s attorney general alleged in a 2020 complaint that DuPont deliberately understated the liabilities transferred to Chemours to shield billions in assets from cleanup costs and tort claims.² Chemours itself sued DuPont in May 2019 in Delaware’s Court of Chancery, alleging the transferred liabilities had been “systematically and spectacularly wrong” and that Chemours was effectively insolvent from day one.³

That fight was resolved in January 2021 with a Memorandum of Understanding among Chemours, DuPont, and Corteva (which had been carved out of DuPont in 2019). The MOU makes Chemours responsible for 50% of qualifying PFAS expenses, with DuPont and Corteva together covering the other 50% up to a combined $2 billion cap. Total spending under the arrangement is targeted at $4 billion, and the agreement terminates at the end of 2040 or when that target is reached. The parties also released each other from claims over the 2015 spinoff.⁴ This 50/50 framework now sets the financial terms of nearly every subsequent settlement.

The $1.185 Billion Public Water Systems Settlement

In June 2023, Chemours, DuPont, and Corteva agreed to resolve PFAS drinking water claims brought by a nationwide class of U.S. public water systems. The deal was reached within the AFFF (aqueous film-forming foam) multi-district litigation in the U.S. District Court for the District of South Carolina, and Judge Richard Gergel granted final approval in February 2024.⁵

The total is $1.185 billion. Chemours contributes $592 million, DuPont $400 million, and Corteva $193 million.⁶ The class covers public water systems that have detected PFAS or are required to monitor for it. The settlement does not cover personal injury claims or state attorney general natural resource damage claims; both remain live.

The $2 Billion New Jersey Settlement

On August 4, 2025, Chemours, DuPont, and Corteva reached a settlement with New Jersey valued at up to $2 billion, resolving a 2019 state lawsuit over PFAS and other contamination at four industrial sites: Chambers Works in Salem County, Parlin in Middlesex County, Pompton Lakes in Passaic County, and Repauno Works in Gloucester County. It also covers statewide claims related to firefighting foam and other PFAS products.⁷

The companies will pay $875 million over 25 years: $225 million in natural resource damages, $525 million toward environmental abatement, and roughly $125 million for legal costs, penalties, and punitive damages. The deal also establishes a $1.2 billion remediation funding source and a $475 million reserve fund, both backed by surety bonds, and requires the transfer of about 73 acres near Ramapo State Forest to the state plus permanent preservation of nearly 1,400 additional acres.⁸

Cost-sharing follows the 2021 MOU: Chemours 50% (about $250 million in present value), DuPont 35.5%, Corteva 14.5%.⁹ In a related transaction, DuPont and Corteva bought Chemours’ rights to certain PFAS insurance proceeds for $150 million, giving Chemours cash to fund its share through at least 2030.¹⁰ Entry of the Judicial Consent Order was expected no earlier than January 1, 2026, following a 60-day public comment period opened on September 2, 2025.¹¹ The settlement preceded what was described as the first pollution trial of its kind in New Jersey history, over the Chambers Works claims before Judge Renée Marie Bumb in Camden.¹²

The $670 Million PFOA Personal Injury Settlement

The first mass resolution came out of DuPont’s Washington Works plant in Parkersburg, West Virginia, which manufactured PFOA (also known as C8) for decades. A 2004 class action settlement worth over $300 million funded the C8 Science Panel, which later linked PFOA exposure to six diseases, opening the door to roughly 3,550 personal injury lawsuits. Three of the first six trial cases produced about $20 million in combined verdicts, including a $12.5 million verdict for a testicular cancer plaintiff in January 2017.¹³

In February 2017, DuPont and Chemours settled the remaining PFOA claims for $670 million, split equally at $335 million each. Each company also agreed to contribute up to $25 million a year for five years toward future PFOA-related costs.¹⁴

The EPA’s $16.5 Million PFOA Penalty

In December 2005, well before Chemours existed, the EPA settled with DuPont for $16.5 million over Toxic Substances Control Act and Resource Conservation and Recovery Act violations tied to PFOA. The penalty included $10.25 million in civil fines and $6.25 million in supplemental environmental projects and was the largest civil administrative penalty the EPA had ever obtained under a federal environmental statute at the time. The violations centered on DuPont’s failure to report substantial risk information about PFOA to the EPA dating back to 1981.¹⁵

The North Carolina GenX Consent Order

In 2017, North Carolina investigators traced GenX, a PFAS compound, in the Cape Fear River back to Chemours’ Fayetteville Works plant in Bladen County. State investigations identified unpermitted PFAS discharges spanning decades, affecting drinking water in at least eight counties.¹⁶

A court-enforceable consent order signed in February 2019 by the North Carolina Department of Environmental Quality, Cape Fear River Watch, and Chemours required a 99.9% cut in facility-wide GenX air emissions, an end to process wastewater discharge, permanent replacement drinking water for households with contaminated wells, and toxicity studies on PFAS compounds. Chemours also paid $12 million in fines and $1 million in investigative costs.¹⁷ A 2020 addendum added obligations for additional downstream counties.¹⁸

Cases Still Active Against Chemours

Cape Fear Utilities Lawsuit

In October 2017, the Cape Fear Public Utility Authority, Brunswick County, the Lower Cape Fear Water and Sewer Authority, and Wrightsville Beach sued Chemours and DuPont in the U.S. District Court for the Eastern District of North Carolina to recover costs from decades of PFAS discharges. The utilities have spent millions on filtration upgrades; Cape Fear Public Utility Authority customers pay a $7.50 monthly surcharge to cover those costs.¹⁹

In December 2025, Judge James Dever III denied motions by Chemours and DuPont to seal approximately 25,000 pages of internal communications and a 2018 EPA inspection report of the Fayetteville Works facility, finding that the companies had not shown a compelling interest that outweighed public access. As of early 2026, it was unclear whether the companies would appeal.²⁰ The case remains active, with the most recent docket entries from May 2026.²¹

North Carolina Residents Class Action

Nix v. The Chemours Company FC, LLC (No. 7:17-CV-189), filed in the same federal court, seeks damages for North Carolina residents and property owners whose water was contaminated by Fayetteville Works discharges. In October 2023, Judge Dever certified two classes, a “public utility class” and a “groundwater class,” covering residents of New Hanover, Bladen, Brunswick, Cumberland, and Pender counties. The Fourth Circuit declined to hear an appeal of that certification in November 2023.²²

In September 2025, the court denied without prejudice the defendants’ motions to decertify the class and for partial summary judgment. No trial date has been set, and court-hosted mediation in September 2023 did not resolve the case.²³ Plaintiffs are seeking monetary damages and injunctive relief for physical injury, property damage, reduced property values, and water filtration costs.

North Carolina Attorney General’s Case

On October 13, 2020, then-Attorney General Josh Stein filed a state court action against DuPont, Chemours, and related entities, alleging decades of knowing PFAS discharges into the Cape Fear watershed, concealment of toxicity data, and a fraudulent spinoff designed to shield assets. The state is seeking remediation costs, natural resource damages, punitive damages, and a judicial declaration voiding the transfer of liabilities to Chemours.²

In November 2022, the North Carolina Supreme Court rejected the DuPont successors’ motion to dismiss for lack of personal jurisdiction, holding that Corteva and the post-merger DuPont entity had expressly assumed the predecessor’s PFAS liabilities and that the state had sufficiently alleged a fraudulent scheme to avoid them. The case was remanded and remains active.²⁴

Personal Injury Claims in the AFFF MDL

The AFFF multi-district litigation in South Carolina encompasses more than 10,000 associated cases involving tens of thousands of plaintiffs, with claims for personal injury, medical monitoring, property damage, and economic losses.²⁵ Personal injury claims were carved out of both the $1.185 billion water systems settlement and the New Jersey deal, so they remain pending against Chemours and its co-defendants.⁶

What Chemours Has on Its Books

As of mid-2023, Chemours reported $148 million in current environmental remediation accruals and $473 million in long-term remediation accruals.²⁶ Through March 2023, roughly $350 million in qualifying spend had already been paid under the 2021 MOU, against the $4 billion overall target.⁶ With the Cape Fear utilities case, the Nix class action, the North Carolina attorney general’s suit, and the personal injury tracks of the AFFF MDL all still open, Chemours’ PFAS bill continues to grow well past the amounts already committed.
