Rye is wrong. Deer Park is the best form of bottled water. Honorable mention goes to Fiji.
Many places in the world can have water that is either contaminated (gee, I wonder if malicious organisms are good for you) or littered with heavy metal ions. Heavy metal ions are not good for you. Mercury and lead are not good for you, and there a great number of places, especially in big cities that have lead pipes. I wonder what those lead water pipes hold. OHH SNAP THEY HOLD TAP WATER? LOL PARADOX
But, if we all want a greener world, what we need to do is buy mass amounts of spray paint cans, and paint everything green.
