I asked for details on the Drinking and Spring water products that they sell at our local Fred Meyer grocery store (a Kroger chain). Our water in Seattle is actually good, I was just interested in seeing how this water was because for a buck or two sometimes it's easier to buy some to supplement your water. The results that came back on the Drinking water product were all "None Detected" for everything I asked for (Alkalinity, Ca, Mg, Sulfate, etc...).
Is that actually possible? I would have expected that from a Distilled water, but not the Drinking water product. The Spring water, which I also asked for, actually had numbers which makes perfect sense.
BTW, this is what they gave me if anyone else is interested:
