Tapwater in Iceland is safe to drink. Went there a couple of years ago and spoke to the locals regarding bottled water. They told me that the bottled water is the 'same' water I get from the tap.
In France I once went to a water museum, yes those exist. They told us that tapwater is safe to drink and that we should stop buying bottled water.
I live in The Netherlands myself and I don't know better then drinken water from the tap. I would go as far as saying that we are among the countries with the best tapwater in the world.
'Stop asking this' is not a really helpful thing to say. We have a lot of new users, including myself, and everybody is figuring out how Lemmy works. Redundant questions will occur and let's answer those in a respectful manner.
