Department of Defense Report Confirms PFAS Play Vital National Security Role

A new report by the Department of Defense (DoD) confirms that certain PFAS remain mission-critical to U.S. national security and readiness through their essential roles in semiconductors, batteries, protective gear, and more. The 2025 DoD Update on PFAS Critical Uses reinforces existing research that alternatives for many defense applications are not readily available, and would necessitate a multi-decade effort to develop and implement suitable replacements. 

The report outlines a phased, science-based approach focused on identifying essential uses, investing in long-term research and development, and pursuing viable substitutes once they are developed. 

The report’s approach of characterizing compounds emphasizes the need for collaboration across government, industry, and academia to drive innovation without compromising readiness or performance. This further underscores the urgent need for clear, effective federal PFAS policy that protects human health without undermining American innovation, national security, and economic competitiveness. The report emphasizes the risk presented by a patchwork of ineffective state-level laws, which could lead to reliance on foreign production and threatens the stability of international supply chains.

Certain PFAS have critical applications to the 21st century economy, including defense. DoD’s assessment is in line with SPAN’s recommendation for the EPA to establish a uniform, risk-based policy model that will give guidance to the states, thereby preventing overly broad and inconsistent laws.
