I bought some Glaceau smartwater, ‘vapor distilled water and electrolytes for taste’. It says
then it goes on to claim that it is ‘purity you can taste’ and in its “purest original state”. Is spring water (bottled) filled with frog spit? or is smartwater pushing the old marketing bs at us suckers?
With apologies to logical construction, the answer to you ‘or’ question is:
Yes.
My well water comes from a rock vein 200 feet under ground. In order to reach that level it is naturally filtered through layers of soil, clay, sand, etc. It’s perfectly acceptable and has been tested as such.
Now if you were to scoop water out of a pond or lake, that would be a different story.
Yes, indeed. I’ve heard that the standards for spring water are lower than tap water, so with spring you can get good or bad.
You have to admire them for putting that right on their label, though. Many water companies go through pains to hide the fact that they’re just local tap water put through a filter, with a $1.00-2.00 price tag stamped on.
I once had a bottle of “glacier water” at work and was mocked for drinking preserved eskimos. 
I don’t admire them because they are inferring that spring water has “whatever else the animals that swim in it leave behind”. It’s spring water, not pond or stream water. Deer and woodchucks don’t routinely take dumps hundreds of feet below the surface. I would much rather drink something out of a spring than something that quiet recently had been in someones bladder, regardless of how well it’s been filtered and disinfected. Just sayin’.
