I see a lot of people at least joking about going vegan lately. I've been vegan for roughly.... ah, I want to say 4 years now? I lost track awhile ago. It was around the time the wreckers came to Hexbear and convinced a bunch of us to watch Dominion (highly recommend doing so btw, it's free online).
ANYWAYS, if you're interested in more than just shitposts and are seriously interested in veganism I was thinking I could help answer any questions you have. Comment here or send me a DM if you're blush shy. 
This comm has limits on what we can talk about btw, such as diet. And I think the whole website has restrictions on recommending specific brands of food? So DM for questions like that, thanks.

This guy ran distilled water in a closed system for 24 hours and tested it with 0 PFAS, put an arcteryx jacket and ran it for another 24 hours. The results were PFOA: .65 ppt PFBA: 21 ppt
He also tested his blood which was around 1000 ppt of PFOA, and apparently that is below the national average of around 4000 ppt.
Pretty terrible situation, but I guess all we can do is try to limit it in the ways that we have control over. I wonder if the effort it takes to do this is truly worth it, but there's literally no way to know so I'll take my chances trying to avoid it as best as possible.
I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
The 10 States Standards states are working to include PFAS rules. The issue is that most current treatment stacks do not remove PFAS/PFOA effectively. It's mostly a point of discharge and industrial use restriction problem which the US does not do well already---nevermind the hamstringing coming down currently. EPA was moving to make PFAS/PFOA rules which have been walked back by Trump.
