Maybe you could tell us what year it would be where there was no PFAS and then all of a sudden there's PFAS.

Yeah.

So it's about sometime in the 1940s was when the first PFAS was created.

They are a family of man-made chemicals.

So, you know, there's nothing that existed before them.

So if you actually go into historical records, you could, you know, before the 1930s, there was no PFAS.

And like those water samples or, you know, core samples, et cetera.

Well, I feel like we'd be remiss if, as we're talking about some of these issues and efficacy, that we didn't at least address what are some of the steps that people can actually take to protect themselves against PFAS.
