Ah yes, it's totally the fault of the occasional use of firefighting foam, and not the fault of literally every single food package being covered in the stuff.

Do you have numbers to back up your assertion?

Food packaging? Do you have a citation for that? Cookware yes, but packaging?

Absolutely used in food packaging. Even the inside of microwave popcorn bags has it. Just google "PFAS food packaging" and you'll lots of info.

If we're talking about groundwater contamination, then yes, the major contributor is firefighters and US Government facilities based on the numbers I've seen. It's not food packaging making it hundreds of feet underground and leaching out into rivers.

Scroll through these 180 pfas contamination Superfund sites and count how many are government facilities versus private companies.

I'm mostly talking about breadth of harm, ie that PFAS is quite literally everywhere, rather than depth of harm, ie a couple hundred rivers have been made into poison. If the damage was exclusively contained to these rivers, the cleanup would be obscenely expensive, but possible. Currently cleanup is basically impossible.

I live on the site of a building rebuilt 13 years after a fire that was attempted to be put out by firefighters. Would that foam have contaminated the well water I drink from?
