For decades, Aqueous Film-Forming Foam (AFFF) was considered essential for firefighting, especially in high-risk environments like airports and military installations. While effective against fuel-based fires, AFFF introduced a serious long-term problem: PFAS contamination.

Even after departments stop using AFFF, PFAS does not simply disappear. These “forever chemicals” remain embedded inside ARFF vehicles, fire trucks, foam tanks, piping, and proportioning systems. Over time, this creates ongoing exposure risks for firefighters and contamination risks for facilities.

Many organizations assume that draining foam tanks or rinsing systems solves the issue. Unfortunately, PFAS binds to internal surfaces and can reappear during future use, maintenance, or cleaning. This leads to secondary contamination of rinse water, equipment, and surrounding areas.

Firefighters face increased occupational exposure when handling contaminated systems, especially during routine inspections or training exercises. Beyond health concerns, unmanaged PFAS also creates regulatory and liability risks for organizations responsible for firefighting readiness.

Proper PFAS decontamination requires more than removal—it requires verified destruction of PFAS compounds using controlled, documented processes. Mobile, on-site treatment allows departments to address contamination without transporting hazardous materials long distances.

Understanding where PFAS hides is the first step toward protecting firefighters, meeting compliance requirements, and moving forward safely.
