Biggest Money Drainer: Bottled Water. Despite what many consumers believe, pricy store-bought H2O isn’t always purer than tap. Tap water is required to undergo annual testing for contaminates, and towns and cities must share the results with the public, says Todd Jarvis, associate director of the Institute for Water and Watersheds at Oregon State University. On the other hand, makers of bottled water are largely responsible for their own testing, and they don’t have to report their findings. “Some brands are filters and treated more than tap water, while some brands don’t receive any additional treatment,” Jarvis says.
