Current Number of AFFF Lawsuit Filings

The current number of AFFF lawsuit filings has grown a lot, showing rising concern over health and environmental risks from PFAS (per- and poly-fluoroalkyl substances) exposure. Starting with 2,120 cases in early 2022, the number grew significantly, reaching a total of 19,820 cases by June 2026.

This rise shows a big increase in AFFF lawsuit cases filed, especially throughout 2025, when many more people and communities sought legal action for the harms linked to long-term PFAS exposure. Filings have slowed sharply in early 2026. This earlier surge likely reflected growing awareness and evidence connecting PFAS to serious health problems.

New numbers of AFFF lawsuit cases filed show a fluctuating but generally rising trend in litigation. Starting in early 2022 with low numbers, filings increased significantly, reaching a peak of 200 new cases in July 2022. The upward trend continued into 2023, with a notable surge of 442 cases filed in June. In 2024, litigation accelerated further, reaching a new record high of 959 cases in June. The momentum continued into 2025, which proved to be an exceptionally active year. May and July 2025 each recorded 1,060 filings, followed by a record-breaking 1,550 cases filed in October 2025. Following that peak, new filings dropped sharply, falling below 100 per month and then to just 2–10 new cases per month from January through May 2026.

Why Are Plaintiffs Filing AFFF Lawsuits?

The large and increasing number of AFFF lawsuits highlights the severity of this issue. Plaintiffs are filing these lawsuits primarily due to serious health conditions linked to AFFF exposure, including cancers such as kidney, testicular, and pancreatic cancer, as well as other illnesses like immune system disorders and reproductive issues. A significant portion of the plaintiffs includes firefighters and military personnel, such as Navy service members, who were frequently exposed to AFFF during firefighting training or emergency responses.

As legal proceedings continue, more plaintiffs are likely to join, adding to the overall case count. The high volume of cases also means that courts will need to manage these claims carefully, potentially leading to mass settlements or other legal resolutions to address the widespread harm caused by AFFF.

Conclusion

A significant number of AFFF lawsuit cases have been filed. Although the pace of new filings has slowed sharply in 2026 after a record-setting 2025, the large body of AFFF-related claims continues to move through the courts. These cases underscore the importance of holding manufacturers accountable for the health impacts of AFFF and may lead to more comprehensive legal resolutions in the future.
