The Bottled Water Facts Concerns about the purity and safety of our public water supplies have created a demand for a safer choice of drinking water. Before you choose bottled water as an alternative, know the facts. Make a wise choice for you and your family. Source Legally accepted sources are wells, springs and even public tap water. Most sources have some form of contamination.
