What happens is someone will point to anyone of these chems and say "that level is safe." Perhaps. But no one has an understanding of them and what happens when you combine trace amounts of Chem X, Chem Y and Med Z. At that point any judgement of safety breakdowns.

Here is more detailed report on this problem in Europe [1] They seem to indicate levels many times higher are present in Europe than the EPAs suggested limited of 70 PPT. Although that limit also seems to be commonly exceeded in US. It is concerning that technical discussion over regulation is occurring while the picture of actual contamination levels is very incomplete [2]

If there was a magical way of convincing every single person in the U.S. to stop buying X, what would we have to stop buying to stop this pollution?

Industrial pollution like this is the lived reality of Capitalism and it’s inability to meaningfully account for the environmental degradation and destruction it causes. The problem isn’t “stop buying X” it’s that we need to “stop buying.”

Teflon for example, is pretty stable when manufactured and in-application. But the company manufacturing it, DuPont, has shown despicable disregard for environment and people health and as such, imo, should get a healthy dose of "I ain't touching your products". edit: one example, https://www.nytimes.com/2016/01/10/magazine/the-lawyer-who-b...

I don't even know if most recent teflon products are supposed to be "safe" when scratched or otherwise, but I've been buying and recommending everyone to stay away from teflon products and buy only ceramic or stainless steel ones for a few years now.

I've noticed there are a lot of ceramic alternatives to teflon these days compared to a few years ago and it's not much more expensive. I do believe ceramics aren't 100% safe for certain applications either, such as boiling sour stuff, or something along those lines.

I would be interested to know what is the current trust level of the residents on the gov and EPA in the different states.

Not far from my living area a new gas rig started operating where the gov, contractor company and EPA (EPA of my country that is) argue the chemical emissions doesn't pose health risks (same for sea water pollution risk), while self-funded environmental organizations argue otherwise and show inconsistencies and omissions of real-time data in air monitoring stations. They compare the owners' claims with their assertions.

The interesting story is about trust crisis in the system. The public reached a point where they started crowd-funding independent air monitoring system to put pressure on EPA to "do its job" and enforce the standards. EPA already announced a nice mobile app showing monitored air data on the map to provide public sense of security. I hope the data is genuine.

There are more and more examples of crowd-funded projects as alternatives to governmental components expressing decline of public trust.

It seem to happen globally on many levels. Is it possible the crowd-funded organizations will one day replace the government?

Apparently there are now technologies available to remove PFAS from water: https://cen.acs.org/environment/persistent-pollutants/Foreve... but it is going to be expensive to deploy everywhere that it is needed.

I think britAs and the like work somewhat at removing pfas. They’re large organic molecules and they excel at removing those.

Based on internet it seems zerowater filters are much more effective than brita, but they cost a bit more to run (because, well, they filter out more stuff).

"The United States has among the cleanest air and drinking water on Earth."

Large country, so probably true for the most remote locations.

Remote locations are where companies frack and spill oil and coal waste with impunity. People are also more likely to drink well water there (apparently 15% of Americans rely on it).

Coming from a rural place where water smelled like rotten eggs on a good day, I doubt the veracity of the claim.
