I also thought about case where 
water is commonly used as a drinking water
(for example camp site in mountains),
but there is no official testing or
official permission or any official oversight.

So in this case, he would need to leave drinking_water      untagged. But what he can with certainty record is that there is      no official information about it whatsoever. This is useful      because people searching for drinkable water would certainly      prefer water sources where it is positive that it is drinkable.      drinking_water=unknown or drinking_water:signed=no would solve      this, but there is also case 4.
