I just read this briefly . . . A few sentences gave me the impression the regulators are be saying that bottled water is no better than tap water for hydration.
In the U.S. bottled water produces regularly make claims (or insinuations, really) that their product is particularly "pure" or good for you. These claims are rubbish; bottled water in most U.S. cities is as contaminated, or more contaminated, than tap water. U.S. regulators should crack down on these claims. - Jed
