Hi, Russ and others:
Regarding the addition of fluorides to bottled water, here is a case in point from Canada:
There was a bottled water company called Aberfoyle, their water was from unpolluted aquifer in the North. (I talked to a company owner, he was supplying water to one marathon as a promotion)
Then that company was bought over by a big international corporation. They changed the name and the label, there was no more mention of the aquifer, only the location of the bottling plant - right within the industrialized zone. And now there is fluoride!
The new label says:
"Ozonized. Natural spring water. Sodium free. Mineral salt content 480 ppm / Fluoride ion 0.3 ppm"
This is described on my site www.deadwater.info/survive.htm
I doubt that a multi-billion dollar company cannot retain qualified scientists to advise them about fluorides and the potential liability. The answer to that riddle is probably not "honest science" but smth else.

best regards
Oleg
