EPA determines formaldehyde poses an 'unreasonable risk' to humans and must be regulated

As I mentioned above - there is so much stuff that used it over the centuries that to try to tackle how to start to remove it, is daunting.

It's just like dealing with phasing out the coolants (like Freon) that were blowing holes in the Ozone layer of our atmosphere and coming up with alternatives while laying out a timeline to transition out of the use of it, and find ways to dispose of it. In the case of the coolants, the effort started back in the late '80s finally leading to a phase out starting over 30 years ago, and finally a ban of the latest version of it just under 5 years ago.

Similarly we are seeing how PFAS is finally being handled as another one of those groups of chemicals that have been around for some time and are everywhere - with a need for a process to help transition out of their use and come up with disposal solutions.
