What's in a Bottle of Water?
Purified Water: Most likely municipal tap water that has been distilled or treated with a process like deionization or reverse osmosis to remove impurities. The two major bottle drinking water, Dasani and Aquafina, are purified.
Spring Water: Comes from an underground formation from which water flows naturally to the surface of the earth. May be collected only at the spring through a borehole tapping the underground formation that feeds the spring.
Mineral Water: Contains not less than 250 parts per million total dissolved mineral solids when it emerges from its source. No minerals can be added.
Sparkling Bottled Water: Contains the same amount of carbon dioxide that it had as it emerged from its source. (Companies sometimes add CO2 to replace what's lost during bottling.) Depending on the source, it may be labeled something like "sparkling drinking water," "sparkling mineral water," or "sparkling spring water."
