Researchers from Washington University in St. Louis have solved a mystery: How did arsenic show up in aquifer water that had been triple purified? Dissolved organic compounds.

You may be wasting your money, says an expert in aquatic chemistry. Daniel Giammar, Ph.D., a faculty member in the Environmental Engineering Science Program at Washington University in St. Louis, says that tap water is just as safe to drink as bottled water. He also says that the pricey bottled water you value so highly might well be nothing more than repackaged tap water. “The tap water we drink meets very strict standards that are designed to protect our health,” Giammar says. “These are developed over many years of study and they all include fairly large factors of safety. Any differences between tap and bottled water, in terms of health, are negligible.”
