Yes, there really are different
types of water. According to the
International Bottled Water Association,
definitions on the different types of bottled water
are:4
Artesian Water: 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.
Spring Water: Water derived from an underground
formation from which water flows naturally to the surface of the earth.
Purified Water: Water that has been produced by
distillation, deionization, reverse osmosis, or other suitable processes.
Distilled Water: Water that has been vaporized into
steam, then cooled to re-condense it back into water. The water's minerals
are left behind, leaving only pure tasting steam-distilled water.
Mineral Water: Water that contains no less than 250
parts per million (ppm) total dissolved solids (TDS).
Sterile Water: Water, also known as sterilized water,
that meets the requirements under Sterility Tests, in the United States
Pharmacopeia, 23d revision.
Carbonated water products (soda water, seltzer water,
sparkling water, and tonic water) are considered soft drinks and are not
regulated as bottled water.
