Spring Water : Bottled water derived from an underground formation from which water flows naturally to the surface of the earth. Spring water must be collected only at the spring or through a borehole tapping the underground formation feeding the spring.

Purified Water : Water that has been produced by distillation.

Mineral Water : Mineral water is distinguished from other types of bottled water by its constant level and relative proportions of mineral and trace elements at the point of emergence from the source.

Sparkling Bottled Water : Water that after treatment, and possible replacement with carbon dioxide, contains the same amount of carbon dioxide that it had as it emerged from the source.

Artesian Water : Bottled water from a well that taps a confined aquifer (a water-bearing underground layer of rock or sand) in which the water level stands at some height above the top of the aquifer.

Well Water : Bottled water from a hole bored, drilled or otherwise constructed in the ground, which taps the water aquifer.
