In Belgium there is a huge issue with pfas caused by 3M [1], having contaminated things like drinking water etc, so it's not even safe to eat vegetables from your garden or eggs from your chickens.

It's a massacre TBH, mostly exposing the head-in-the-sand, umbrella using fingerpointing mentality of Belgian politics. I can imagine 3M has sites like these all over the world, so I would assume this only scratches the surface...

Edit: typos, it's early in the morning here ...
