No, there are actually different types of water which fall under the category of "bottled water". According to the FDA the following definitions describe the different types of bottled water: Artesian well water Water from a well tapping an aquifer in which the water level stands at some height above the top of the aquifer. Ground water Water from a sub-surface saturated area that is under pressure equal to or greater than atmospheric pressure. Mineral water Water containing not less than 250 parts per million total dissolved solids (TDS), coming from a source tapped at one or more bore holes or springs, originating from a geologically and physically protected underground water source. No minerals may be added to this water. If TDS content is below 500 parts per million, the statement "low mineral content" must appear on the label. If TDS content is above 1500 parts per million, the statement "high mineral content" must appear on the label. Purified water Water that has been produced by distillation, deionization, reverse osmosis, or other suitable processes and that meets the definition of "purified water" in the 23d Revision of the United States Pharmacopoeia. Sparkling bottled water Water that after treatment and possible replacement of carbon dioxide, contains the same amount of carbon dioxide that it had at the emergence from the source. Spring water Water derived from an underground formation of water flowing naturally to the surface of the earth. Spring water is collected only at the spring or through a bore hole tapping the underground formation feeding the spring. Sterile water Water meeting the requirements under the "Sterility Test" in the 23d Revision of the United States Pharmacopoeia. Well water Water from a hole in the ground which taps the water of an aquifer.
