I live in an area with PFAS contaminated ground water (which I now aggressively filter.) To me giving blood just kind of makes sense, if there is a class of things that can enter your blood and never leave, and does not replicate on its own, why not perform a regular "oil change" and hopefully help some people at the same time. Some study has been done:

The study specifically does not look at the effect on recipients, though the donation centers do not disallow such donations. My presumption is that the donation is a net positive all around. If study comes to show the contrary, I'll certainly revise my approach.

“I’ll do something which might be beneficial or harmful to me (I don’t know) and if given evidence of harm (likely never) I’ll stop doing it.” Ok…have fun I guess.

The person you responded to didn't say anything about harm to themselves. They said there's nothing stopping them from donating even though they're aware of the PFAS contamination in their area.

And from what I understand, PFA contamination has no bearing on whether or not you can donate.
