IMPORTANT: Some states (such as Texas) now require bottled water to be subjected to germicidal treatment (i.e. water shall be subject to effective germicidal treatment by ozonation, chlorination, exposure to ultraviolet light, or other equivalent disinfection). Your bottled water may contain chlorine even if the bottle water is marked ‘natural spring water’. Please open bottled water and allow to age (in full sun) for at least 48 hours before using. All kits are now shipped with natural water conditioners. Please follow the instructions on package of conditioner.

The names of water per 21 Code of Federal Regulations Part 165.110.

Bottled water - Water that is intended for human consumption and that is sealed in bottles or other containers with no added ingredients except that it may optionally contain safe and suitable antimicrobial agents. The name of the food is “bottled water” or “drinking water,” or alternatively one of the following terms as appropriate.

Artesian water - Water from a well tapping a confined aquifer in which the water level stands at some height above the top of the aquifer is “artesian water” or “artesian well water.” Artesian water may be collected with the assistance of external force to enhance the natural underground pressure.

Mineral water - Water containing not less than 250 parts per million (ppm) 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. Mineral water shall be distinguished from other types of water by its constant level and relative proportions of minerals and trace elements at the point of emergence from the source, due account being taken of the cycles of natural fluctuations. No minerals may be added to this water.

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 United States Pharmacopeia, 23d Revision, January 1, 1995, which is incorporated by reference in accordance with 5 U.S.C. 551(a) and 1 CFR part 51.

Deionized water - Water which has been processed by deionization.

Reverse osmosis water - Water has been processed by reverse osmosis.

Distilled water – Water which is produced by distillation.

Sparkling bottled water - The name of water that, after treatment and possible replacement of carbon dioxide, contains the same amount of carbon dioxide from the source that it had at emergence.

Spring water - Water derived from an underground formation from which water flows naturally to the surface of the earth. Spring water shall be collected only at the spring or through a bore hole tapping the underground formation feeding the spring. There shall be a natural force causing the water to flow to the surface through a natural orifice. The location of the spring shall be identified.

Well water - Water from a hole bored, drilled, or otherwise constructed in the ground which taps the water of an aquifer

Ground water - Water from a subsurface saturated zone that is under a pressure equal to or greater than atmospheric pressure. ” Ground water must not be under the direct influence of surface water as defined in 40 CFR 141.2.
