I was wondering the same thing. I found this in a guardian article

> The military’s firefighters use aqueous film-forming foam, or AFFF, which contains extremely high levels of PFAS, in training exercises and emergencies. Though AFFF is effective, it has led to widespread contamination around bases and airports, and Congress just mandated the military check for PFAS pollution at 700 facilities while earmarking $571m for cleanup, though observers say the cost will likely be much higher.
