Bottled water basically the same as tap water?

Robert Siegel interviewed Charles Fishman, a reporter for the magazine Fast Company, who says that Pepsi's Aquafina and Coke's Dasani are basically purified tap water. No magical springs bubbling out of a picturesque hillside in some rural American forest, visited by locals for years. Just plain old tap water. The companies say they put the tap water through an "energy-intensive reverse-osmosis filtration process," but, to the author, that seems like basically the same stuff we get by running our tap water through a Brita filter.
