Demonstration and Validation of Environmentally Sustainable Methods to Effectively Remove PFAS from Fire Suppression Systems
Research funded by the Department of Defense has demonstrated a promising technology for flushing PFAS from firefighting systems in air hangars and firetrucks, which could be used to address not only a congressionally mandated ban on the department’s use of the chemicals in firefighting foam but also a growing number of state restrictions on the use of the foams at non-military facilities.

Toxicology Assessment for Six PFAS-Free Aqueous Film Forming Foam (AFFF) Products
A new study by U.S. Army researchers on the alleged toxicity of PFAS-free firefighting foams has identified tradeoffs among the products examined for short-term exposure risks, even while minimizing the likelihood of environmental persistence and bioaccumulation, underscoring the challenges Department of Defense acquisition officials face in phasing out use of the chemicals.

Bayesian Estimation of Human Population Toxicokinetics of PFOA, PFOS, PFHxS, and PFNA from Studies of Contaminated Drinking Water
This study estimates population toxicokinetics, such as PFAS half-lives and volumes of distribution, using an integrative approach that combines individual-level data from multiple studies on drinking water contamination.

Presumptive Contamination: A New Approach to PFAS Contamination Based on Likely Sources
This report provides a map of presumptive PFAS contamination sites in the United States to identify and prioritize sites for monitoring, regulation, and remediation. Over 57,000 sites were identified, including AFFF discharge sites, industrial facilities that produce or use PFAS, and sites related to PFAS-containing waste.
