‘A 1999 study by the National Resources Defense Council of more than 1,000 bottles of water found that, while most bottled water was safe, some brands violated strict state standards on bacterial contamination, while others were found to contain harmful chemicals such as arsenic. The report concluded that bottled water was no safer than water taken from the tap.

In fact, many times bottled water is tap water. Contrary to the image of water flowing from pristine mountain springs, more than a quarter of bottled water actually comes from municipal water supplies. The industry is dominated by three companies, who together control more than half the market: Coca-Cola, which produces Dasani; Pepsi, which produces Aquafina; and Nestlé, which produces several "local" brands including Poland Spring, Arrowhead, Deer Park, Ozarka and Calistoga (a fact that itself often surprises participants in the Tap Water Challenges). Both Coke and Pepsi exclusively use tap water for their source, while Nestlé uses tap water in some brands.

Of course, Coke and Pepsi tout the elaborate additional steps they take that purify the water after it comes out of the tap, with both companies filtering it multiple times to remove particulates before subjecting it to additional techniques such as "reverse osmosis" and ozone treatment. Reverse osmosis, however, is hardly state of the art -- essentially consisting of the same treatment applied through commercially available home tap water filters, while ozonation can introduce additional problems such as the formation of the chemical bromate, a suspected carcinogen. In March 2004, Coca-Cola was forced to recall nearly 500,000 bottles of Dasani water in the United Kingdom due to bromate contamination that exceeded the U.K. and U.S. limit of 10 parts per billion. This past August, three grocery stores chains in upstate New York who all used local company Mayer Bros. to produce their store brands issued recalls after samples were found contaminated with more than double the bromate limit; in some cases, contaminated water was apparently sold for five weeks before the problem was detected.’
