For Your Health—Drink Tap Water

Americans spend about $9 billion per year on bottled water. Many buy bottled water because they want to avoid the chemical treatments used to purify tap water. A new study by Dutch researcher Rocus Klont found evidence of bacterial contamination in 40 percent of 68 different brands of bottled water he tested. "These findings indicate that the general perception that bottled water is safe and clean is not true," Klont said to Reuters Health.
