Where Accountability Meets Stewardship
A Shared WEL and JAW Perspective on the Federal PFAS Decision
On August 18, 2026, a three-judge panel of the U.S. Court of Appeals for the DC District issued a decision that could shape the future of PFAS regulation, remediation, and environmental accountability across the United States. In a unanimous ruling, the court upheld EPA's designation of two well-known PFAS compounds, PFOA and PFOS, as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund.

The decision preserves EPA's authority to investigate releases of these chemicals and pursue responsible parties for cleanup costs. It also represents an important legal affirmation that PFAS contamination poses sufficient environmental and public health concerns to warrant federal oversight under one of the nation's most significant environmental laws.

The Challenge
The case originated from challenges filed by several industry organizations, led by the U.S. Chamber of Commerce. The petitioners argued that EPA overstated the risks associated with PFOA and PFOS, failed to adequately consider economic consequences, and did not properly justify its designation of the chemicals as hazardous substances.

The court disagreed.
Writing for the panel, Judge Patricia Millett concluded that EPA reasonably evaluated the scientific record, adequately considered public comments, and acted within its statutory authority. Judges Gregory Katsas and Neomi Rao joined the opinion, making the ruling unanimous. [eenews.net], [yahoo.com]
In practical terms, the court determined that EPA's decision-making process was sound and that the agency's interpretation of its authority under CERCLA was lawful. [mondaq.com], [businessin...urance.com]
Why the Decision Matters
By upholding EPA's rule, the court preserved several important regulatory tools:
EPA may continue to investigate releases of PFOA and PFOS.
Responsible parties may be required to fund cleanup and remediation activities.
Federal and state agencies retain access to Superfund enforcement mechanisms.
Cost recovery actions remain available where contamination can be traced to responsible entities.
For environmental professionals, municipalities, and property owners navigating PFAS concerns, the ruling provides legal certainty at a time when PFAS regulation continues to evolve rapidly.
Implications for Florida
Florida has no shortage of locations where PFAS contamination concerns have emerged. Airports, military facilities, fire training centers, industrial properties, wastewater treatment systems, and landfills are among the site types that have drawn increased attention from regulators and researchers.
As investigations continue throughout the state, the court's decision ensures that EPA retains an important mechanism for holding responsible parties accountable when contamination is identified. For local governments and communities evaluating potential PFAS impacts, the ruling helps reinforce the legal framework surrounding future assessment and cleanup efforts. [eenews.net], [notus.org]
The WEL Perspective
Like JAW, WEL believes meaningful environmental progress begins with accountability and stewardship.
The court's decision reinforces both principles by preserving EPA's authority to hold PFAS polluters responsible for contamination while supporting the long-term protection of affected communities and natural resources. The ruling does not eliminate PFAS contamination, nor does it instantly improve impaired waterways, soils, or wetlands. What it does provide is legal clarity.
Polluters remain accountable. Agencies retain authority to investigate contamination. Communities retain a pathway toward remediation.
For environmental consultants, landowners, local governments, and nonprofit organizations, the decision confirms that scientific evidence supporting PFAS regulation continues to withstand judicial scrutiny. EPA's authority under Superfund remains intact, and the framework for addressing contamination remains in place. [eenews.net], [mondaq.com]
Looking Ahead
PFAS litigation is far from over. Additional regulatory actions, liability questions, and cleanup technologies will continue to evolve in the years ahead. Policymakers, industries, utilities, and environmental organizations will undoubtedly continue debating how best to address contamination while balancing economic and practical considerations.
For now, however, one important question has been answered.
The D.C. Circuit has affirmed EPA's authority to designate PFOA and PFOS as hazardous substances under CERCLA, preserving a cornerstone of the federal government's response to PFAS contamination.
For communities affected by forever chemicals, the decision strengthens a fundamental principle of environmental law: those responsible for pollution should not be relieved of responsibility simply because the consequences persist for generations.
Where accountability meets stewardship, progress becomes possible.
