Spring Water is 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. Spring water collected with the use of an external force must be from the same underground stratum as the spring, must have all the physical properties before treatment, and must be of the same composition and quality as the water that flows naturally to the surface of the earth
Purified Water is water that has been produced by distillation, deionization, reverse osmosis, or other suitable processes while meeting the definition of purified water in the United States Pharmacopoeia. Other suitable product names for bottled water treated by one of the above processes include "distilled water" if it is produced by distillation, "deionized water" if it is produced by deionization, or "reverse osmosis water" if the process used is reverse osmosis. Alternatively, "drinking water" can be used with one of the purifying terms defined above
Mineral Water is natural water containing not less than 250 parts per million total dissolved solids. 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. No minerals can be added to this
Sparkling Bottled Water is 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. Sparkling bottled waters may be labeled as "sparkling drinking water"
Artesian Water/Artesian Well Water is 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 is water from a hole bored, drilled, or otherwise constructed in the ground, which taps the water aquifer.
