Other than the very small amounts of water that get "lost" through chemical reactions converting those molecules of H20 into something else, all of the water that we "use" stays with us. Unlike oil where once we use it up, it is no longer in the same form, water more or less stays the same and thermodynamics gives us a clue to this as there is no energy to be had from water and therefore no conversion of matter into energy no matter what we do with water. We "have" more or less the same amount of water we had a million years ago and we will have the same a million years from now unless we cart it out into space. The issue is what form water comes in and this issue is all a "parts-per-billion" issue meaning that in some cases water is mixed up with salt (in fact 97% of
