Confirming what we already knew

Experiments have shown that there's very little difference between tap water and the stuff you buy in a bottle. In other words, the people who buy bottled water are fools. But didn't we already know that?

For those interested in the differences: tap water contains more flouride (fairly standard in NZ domestic water supplies), while some bottled waters contain levels of boron or bromate (a carcinogen) in excess of NZ drinking water standards.

(Oh, and that's Auckland tap-water at that. People drinking bottled water in Christchurch are even bigger fools...)
