Stricter labeling urged for bottled water

An interesting, but somewhat vague, article from the AP about stricter labeling urged for bottled water. I would have liked to read more specifics about what it is that's wrong with bottled water. My own understanding is that, with time, the plastics of the bottle slowly seep into the water itself (ever drink water that had been sitting around in a plastic container that, when tasted, had a "plasticy" taste?)
I've also read that this effect can be magnified by leaving bottled water sitting out in the sun.

I'd like to see more labeling, and I'd also like to know that the bottled water (until tap) is free of fluoride (which should be avoided in drinking water. See here.)
