The Truth About Bottled Water

It started with Perrier. Somehow, a French company convinced people it's cool to buy bottled water. Today, Evian has surpassed Perrier in sales and now it's the chic French water of choice. Why? It costs about 5 bucks a gallon! Why do people pay so much for something they can get virtually free?
If they're not buying Evian, they buy Aquafina and Dasani and the dozens of new brands that are jumping into this billion-dollar business, including bizarre ones like Venus, the Water for Women, and Trump Ice, with "The Donald" scowling on the label. I'd have to be very thirsty to buy that.
Many people say they buy bottled waters because they taste better. We spoke with people in New York City, asking them why they liked bottled better than tap water.
Even Yale University School of Medicine's Dr. Stephen Edberg, the person whom the International Bottled Water Association told "20/20" to talk to, agreed that bottled water is no better for you. "No, I wouldn't argue it's safer or not safer."
The labels of the bottled waters do suggest they're special. Some show mountains or polar bears or glaciers. You have to look at the fine print to find out Everest Water is not from Mount Everest. It's from Corpus Christi, Texas. Glacier Clear Water is not from a glacier in Alaska. Its source is tap water from Greeneville, Tenn.
Bottom line, if you buy bottled water because you think it's healthier than tap, test after test shows no evidence of that. And if you buy fancy brands because you think they taste better, you're probably just buying the hype. (from ABC news)
