Luckily, here in Scotland the government doesn't add fluoride to the water and our soil doesn't contain any so the water is very soft and nicer than any other water I've had. The springs up in the north are also very clean and pure because of the low population. I've drank straight from the hills before while camping and was perfectly fine.
