You could drink it, but i wouldn't suggest it because you don't know where the water's been, who's touched it, whether the water is purified and actually safe to drink, or any of that. So long answer short, I wouldn't recommend it.
Yes, but always boil water first if it comes from a suspicious source.
The juice was very drinkable
Most well water is drinkable, but should be tested for impurities.
Salt water is not drinkable: the salt must be separated by evaporation, distillation, etc..
No not unless it is purified. No lake water is drinkable due to pollution, bacteria in the water, and other conditions.
The water from glaciers is drinkable. When drinking glacier water, the water must be filtrated first. Filtration of glacier water can be done with a coffee filter.
Yes
No
No.
it is made drinkable by people trying not to pee in there and by cleaning it with a filter tube.
A treated water (to be drinkable) contain only traces of impurities or microorganisms. It is a difference between drinkable water, laboratory water, industrial water, water for irrigation etc.
no ocean water can not be made drinkable by adding salt it would make it even more salty
YES it is because if you drain it and do some tests it is proven to be drinkable
