Water: Distilled vs purified vs everything else

[SludgeMunkey]

Just to add a snippet to John's post-

In the US and Canada it is required by law that water sold as spring water state the source spring (or springs) on the label. Additionally they are to disclose any additives.

Just recently, on a whim I stuck a few samples of various spring waters into a batch of boiler water samples (as we have a pretty extensive chemical analysis done at a lab). The results were rather shocking as better than half of the Big Name US brands tested positive for both chloramine and bromide!
