I'm curious what the alternatives are to PFAS in waterproof-breathable clothing.

Patagonia has been on the case since 2015

But they are just now getting there, planning to end using PFCs (PFAS, PFOS, PFOA) by 2024

It's starting to get more mainstream coverage too

I suspect the REI announcement comes around now because progressive manufacturers are telling them that they can get there by 2024 and REI is trying to signal the others.

I thought it was mostly Teflon. Nope, wrong.

"PFAS are a class of about 15,000 chemicals often used to make products resistant to water, stains and heat. The chemicals are ubiquitous, and linked at low levels of exposure to cancer, thyroid disease, kidney dysfunction, birth defects, autoimmune disease and other serious health problems.

They are called "forever chemicals" because they do not naturally degrade.

The chemicals are thought to be contaminating drinking water for at least 200 million Americans, while watchdogs have identified thousands of industrial polluters. Similar widespread contamination persists throughout Europe."

I thought it was in flame retardants. But I think that's mostly wrong, they just tend to get mentioned together

e.g.
https://www.theguardian.com/environment/2022/may/05/us-child-car-seats-pfas-foxic-flame-retardants-study
https://ehjournal.biomedcentral.com/articles/10.1186/s12940-021-00778-z

There was a big kerfuffle many years ago when tents were required to be flame retardant. Lots of people didn't like that and there was a rush to buy old tents without flame retardant.

Huge discussions going on here on PFAS. We pride ourselfes with some of the cleanest water in the world straight from the tab.
Unfortunately a lot of the wells have way too much PFAS in them.

That's not how we roll in the US. Lots of places with terrible tap water, often from agricultural pollution with the surprise to many people that rural water quality is often much, much worse than in the cities (SFO, NYC and LA long ago "stole" the water they needed from the pure sources in rural areas and then protected those watersheds).

First bullet point: Coming soon!

I heard a phrase recently that, apparently, is quite old (like back to the Roman Empire), but quite a propos for America today: private opulence, public squalor. The former being ultimately a driver of the latter.

Do Brita Filters Remove PFAS – Real World Testing Data
QuoteIf you're wondering do Brita filters remove PFAS from tap water, the answer is no. While activated carbon in a Brita pitcher can remove some of these contaminants from drinking water, it does not reduce their concentration to drinking water standards. Brita filters are not designed to treat PFAS and should NOT be used for this purpose.

QuoteExperts agree that a reverse osmosis system installed under your kitchen sink is the best option available to consumers. Duke tested these systems and found they removed 96% or more of these toxins, with no difference among brands.

They also waste a lot of water – only about 20% of the contaminated water ends being treated. The rest is dumped down the drain.
