PFAS, like nearly everything, has a half-life. As a category so large the half-lives can range from days to thousands of years in a vacuum, but even those with thousand year half-lives can be broken down with catalysis in seconds.

It is new tech on the scale of humanity and we will figure it out.

And fortunately, its NOT in a vacuum. It's being ground down by ordinary weather etc.
