Bottled Water Safety and Purity

How to tell water source and purity from the outside

Confused by competing claims of water source, safety and purity? So were we. Here's a short list to help clear up the cloud:

  • Spring Water: Must flow naturally to the earth's surface from an underground formation; source must be stated on bottled water label.
  • Sparkling Water: Spring water with natural bubbles or with carbon dioxide added.
  • Purified Water: Water (often tap) that is processed to remove minerals and contaminants.
  • Selzer/Soda Water: Usually carbonated municipal water, sometimes filtrated.
  • Mineral Water: Must contain at least 250 parts per billion of naturally occurring minerals.
  • Artesian Water: From tapping a confined aquifer, in which the water level is higher than the top of the aquifer.
