In Switzerland we asked while mountain biking if it was safe to fill up from one of these spring water things we saw everywhere: they would dump into a large log cut out into a sort of sink. They looked at us, puzzled "what do you mean, it's spring water," and they filled their bottles.

Backpacking everywhere in Switzerland people drank directly from these, and from streams And waterfalls, without filtration. And the Swiss are looking for any excuse to have something to spend their money on.
