Spring water I've encountered at the source has always been exceptionally clear. That's sort of the thing about slowly passing through layers and layers of rock - mud doesn't get through. And around here anything labeled natural mineral water must by law come with nothing added or removed (bar co2). Of course that will differ by region. Go outside!
