GenX Chemicals Chemours Lawsuit — Cape Fear River

What Are GenX Chemicals and Why Are They Different?

GenX chemicals — technically HFPO-DA (hexafluoropropylene oxide-dimer acid) and its ammonium salt — are a newer class of PFAS developed by DuPont and its spinoff Chemours as a replacement for PFOA in fluoropolymer manufacturing. DuPont and Chemours marketed GenX as a 'safer' PFOA alternative, but subsequent research has found that GenX has many of the same toxic properties as PFOA, including liver and kidney toxicity in animal studies, potential carcinogenicity, and the same environmental persistence that defines all PFAS. The EPA included GenX (HFPO-DA) in its April 2024 National Primary Drinking Water Regulation, setting a maximum contaminant level of 10 ppt — reflecting significant health concern. Chemours' Fayetteville Works plant in Bladen County, North Carolina has been the primary U.S. source of GenX chemical discharge since 2006.

Cape Fear River Contamination — Wilmington NC Ground Zero

Chemours' Fayetteville Works facility sits on the Cape Fear River approximately 100 miles upstream from Wilmington, North Carolina. For years, Chemours discharged GenX and other PFAS into the Cape Fear River through wastewater discharge and air emissions that settled in the river. The public became aware of the contamination in 2017 when a North Carolina State University researcher discovered GenX in the Cape Fear River after Chemours had disclosed the discharge to the EPA without public notification. Subsequent testing found GenX in Wilmington-area tap water at concentrations above health advisory levels. The Cape Fear Public Utility Authority, which provides drinking water to approximately 200,000 Wilmington-area residents, has spent tens of millions of dollars on PFAS filtration. Cape Fear River downstream communities have filed multiple lawsuits against Chemours, and North Carolina reached a consent order with Chemours requiring pollution control measures and community health monitoring.

Who Can File GenX / Chemours PFAS Claims

Wilmington, Brunswick County, and Columbus County residents who consumed Cape Fear River water between approximately 2006 and the present and developed PFAS-linked health conditions may have claims against Chemours. Qualifying conditions include kidney cancer, thyroid cancer and disease, testicular cancer, and other PFAS-linked diagnoses. Agricultural communities along the Cape Fear River corridor who used river water for irrigation or livestock watering may also have exposure claims. Unlike military base claims in MDL 2873, GenX/Chemours claims may also be pursued in North Carolina state court — the state has been active in enforcing environmental laws against Chemours and community plaintiffs have filed both state and federal actions. The fact that Chemours continued discharging GenX after DuPont's problems with PFOA became publicly known strengthens claims that Chemours acted with knowledge and disregard for community health.
