GenX PFAS contamination has produced a stack of legal actions against The Chemours Company and DuPont, including a proposed federal settlement worth more than $450 million announced in June 2026, a 2019 North Carolina consent order with a $12 million penalty and roughly $100 million in required emission controls, a certified class action representing more than 100,000 North Carolina residents, and a separate $1.19 billion industry settlement with public water systems. None of it has fully resolved the contamination that spread from the Chemours Fayetteville Works plant into the Cape Fear River, groundwater, and private wells across multiple counties.1
The Source of the Contamination
GenX is a trade name for a processing aid used to make high-performance fluoropolymers. The chemicals most associated with it are hexafluoropropylene oxide dimer acid (HFPO-DA) and its ammonium salt, part of the per- and polyfluoroalkyl substances family known as “forever chemicals.” Industry introduced GenX as a replacement for PFOA, but the EPA has found the shorter-chain compounds are actually more mobile in soil and water than the older ones.
Chemours manufactured GenX at Fayetteville Works in Bladen County, North Carolina. It reached the environment through air emissions, process wastewater, and groundwater migration. Testing found GenX in private wells nearly six miles from the plant at concentrations up to 4,000 parts per trillion, roughly 30 times North Carolina’s initial provisional health goal of 140 ppt. It was detected in rainwater as far as 21 miles away. In March 2025, the North Carolina Department of Environmental Quality directed Chemours to expand testing eligibility into parts of Harnett and Hoke counties, making roughly 150,000 additional residences eligible for private well sampling.
The $450 Million Federal Settlement
On June 24, 2026, the U.S. Department of Justice, the EPA, and the West Virginia Department of Environmental Protection announced a proposed settlement with Chemours valued at more than $450 million. It covers four facilities: Fayetteville Works in North Carolina, Washington Works in West Virginia, and the Chambers Works and Parlin plants in New Jersey.
The money is allocated across four buckets:
- A $22.5 million civil penalty to the EPA and West Virginia DEP, payable in three annual installments beginning in 2026. The EPA said the amount was assessed based on Chemours’s ability to pay.
- An estimated $280 million to supply alternative drinking water to communities near the West Virginia and New Jersey facilities for more than a decade.
- Approximately $60 million for 14 treatment system projects at the West Virginia facility, targeting PFAS in wastewater, stormwater, and groundwater.
- $90 million over 15 years for a PFAS mitigation program, covering government-supervised emission reduction and off-site drinking water work across the three states.
Federal regulators alleged Clean Water Act violations for PFAS discharges into the Ohio, Cape Fear, and Delaware Rivers, along with Toxic Substances Control Act violations tied to premanufacture notices and to more than a decade of manufacturing PFAS outside enclosed processes. Additional Resource Conservation and Recovery Act allegations focused on shipments of GenX-containing waste from Chemours’s Netherlands facility to North Carolina for long-term storage. According to WRAL, the EPA initially approved import of up to 4.4 million pounds of that waste for recycling at Fayetteville Works, then reversed course in November 2023.
The proposed consent decree was lodged in the U.S. District Court for the Southern District of West Virginia and is subject to a 30-day public comment period and final court approval. Chemours told investors the agreement is not an admission of liability and does not resolve broader risks from legacy PFAS litigation, personal injury claims, or natural resource damages.
Why North Carolina Objects to the Federal Deal
North Carolina was not part of the settlement negotiations, and state officials pushed back hard. Attorney General Jeff Jackson called the agreement “an insult” that does “practically nothing for the state.” He pointed out that the $90 million mitigation pool, divided among three states over 15 years, could work out to roughly $2 million per year for North Carolina. Governor Josh Stein, who launched the state’s original investigation into Chemours as attorney general in 2020, joined Jackson in describing the deal as a “backroom” agreement that lets Chemours choose which projects to fund, with no guaranteed benefit for the state.
Jackson also noted that additional cleanup costs the state orders could be credited against the $90 million pool, cutting its value further. He said the state would keep pursuing its own accountability measures. The North Carolina attorney general’s office has already sued DuPont and Chemours over PFAS contamination in the Cape Fear River Basin, along with six separate suits against 14 manufacturers of PFAS-containing firefighting foam.
The 2019 North Carolina Consent Order
In February 2019, Chemours entered a court-enforceable consent order with the North Carolina DEQ and Cape Fear River Watch, which was represented by the Southern Environmental Law Center. The order required Chemours to stop process wastewater discharges, sharply reduce air emissions, supply replacement drinking water for affected households, and conduct comprehensive groundwater assessments.
The specific requirements included installing a thermal oxidizer, estimated at $100 million, to cut GenX air emissions by 99.9 percent from 2017 levels. Chemours also paid a $12 million penalty and agreed to fund third-party toxicity studies for up to five PFAS compounds.
An August 2020 addendum required Chemours to prevent more than 90 percent of PFAS from entering the Cape Fear River through groundwater, and imposed fines of $5,000 per day to $20,000 per week for missed construction deadlines. The barrier wall and groundwater treatment system began operating on June 11, 2023. By the third quarter of 2025, the combined system had achieved an 88 percent reduction in PFAS mass loading to the river from baseline, ahead of the 75 percent target, and groundwater flow through the old seep pathways had dropped by roughly 94 percent.
In June 2022, after the EPA revised its health advisory for GenX, the DEQ directed Chemours to lower the drinking water eligibility threshold from 140 ppt to 10 ppt, greatly expanding the number of households qualifying for permanent replacement water systems. In November 2021, the DEQ had already determined Chemours was responsible for contamination in four additional counties and ordered an expanded off-site assessment.
The Nix Class Action
Residents and property owners have their own case pending. Nix v. The Chemours Company FC, LLC (7:17-CV-00189-D) consolidates multiple 2017 lawsuits filed by residents of Bladen, Brunswick, Cumberland, New Hanover, and Pender counties in the U.S. District Court for the Eastern District of North Carolina. Plaintiffs allege that since 1980 DuPont and Chemours knowingly dumped toxic chemicals, misrepresented their conduct to regulators, and failed to disclose contamination. The class includes more than 100,000 people seeking damages and injunctive relief for health effects, property damage, reduced property values, and water treatment costs.
On October 4, 2023, Judge James C. Dever III granted the plaintiffs’ motion for class certification. The Fourth Circuit unanimously declined the defendants’ petition to challenge that ruling the following month. Defendants moved to decertify the class in December 2024, and the court denied the motion without prejudice in September 2025. The same order resolved multiple expert challenges and denied a motion for partial summary judgment, also without prejudice. No trial date had been set as of that ruling, and a court-hosted mediation in September 2023 did not produce a settlement.
Public Water System Settlements
Municipal utilities have pursued the same defendants through a separate track. In 2023, Chemours, DuPont, and Corteva announced a combined settlement of about $1.19 billion to resolve claims from public water systems nationwide. Chemours is responsible for roughly half, about $592 million. Eligible systems are those with detectable PFAS levels that must test under EPA monitoring rules. Water utilities in the Cape Fear River Basin were initially excluded from the class but could opt in.
Separately, 3M agreed to pay between $10.5 billion and $12.5 billion in a class action covering public water systems affected by PFAS contamination. Phase Two claims, for systems that first detected PFAS after June 2023, are due by July 31, 2026.
The Cape Fear Public Utility Authority, which serves the Wilmington area, has its own federal lawsuit against Chemours and DuPont to recover more than $92 million spent on PFAS mitigation since 2017, including a $35.9 million granular activated carbon system that came online at the Sweeney Water Treatment Plant in October 2022.
Criminal Investigation
No criminal charges have been filed against Chemours, DuPont, or any of their executives. In July 2017, the U.S. Attorney’s Office for the Eastern District of North Carolina issued a grand jury subpoena to the DEQ for records related to Fayetteville Works, and Governor Roy Cooper directed the State Bureau of Investigation’s environmental crimes unit to assess whether charges were warranted. Neither effort produced charges. In March 2020, the U.S. Attorney’s Office notified Chemours it had declined to prosecute and was closing its file.
Separately, the EPA cited Chemours in 2019 for alleged 2017 violations of the Toxic Substances Control Act, including failing to report the use of certain PFAS and failing to control GenX emissions and discharges. Chemours denied the allegations, and those issues rolled into the broader federal enforcement that produced the 2026 settlement.
Drinking Water Rules Are Still Moving
The federal rules that determine what utilities must actually do about GenX are unsettled. On June 15, 2022, the EPA issued a final health advisory setting a level of 10 parts per trillion for GenX. On April 10, 2024, it finalized the first legally enforceable National Primary Drinking Water Regulation covering six PFAS, including GenX. Chemours challenged the health advisory in the Third Circuit, which rejected the petition in July 2024 for lack of jurisdiction, and filed a separate pending challenge to the 2024 regulations in the D.C. Circuit.
In May 2026, the EPA proposed rescinding the regulatory determinations and maximum contaminant levels for GenX, along with PFHxS, PFNA, and PFBS, citing what the agency called “unlawful procedure” in how the standards were promulgated. The proposal would not affect standards for PFOA and PFOS. A public comment period runs through July 20, 2026, with a virtual public hearing scheduled for July 7, 2026. If finalized, the rescission would eliminate enforceable federal limits for GenX in drinking water, though the EPA said it remains committed to evaluating the compounds for future regulation.
North Carolina has not enacted its own enforceable drinking water standards for PFAS. House Bill 864 in 2023 proposed a 10 ppt limit for individual PFAS compounds and 70 ppt for combined PFAS in public water systems but was not enacted. House Bill 881 in 2025, titled “PFAS FREE NC,” proposed $80 million in water infrastructure grants and technology-based discharge limits; its status is unresolved. Earlier DEQ efforts to establish enforceable PFAS water quality standards were blocked by the Environmental Management Commission’s Water Quality Committee in September 2024.
