Here in the UK we just drink straight from the (cold water only by law due to differring regulations) tap without boiling and that’s been the case for decades at the least across the entire nation. There’s just no need to boil the water here unless you are cooking.
It’s also safe in Iceland, I went there and their water is crystal clear and pure since it’s sraight from the glaciers. You could drink out of a random stream there.
I’ll say it for everyone (and myself), NSFW communities. Reddit is still effectively king for that, at least for now.
