Bottled Water Information
Depending on who you talk to, bottled water can be the best thing to happen to mankind, or the most polluted stuff you can drink.
In fact, some kinds of bottled water are very good and some are not good at all. The trick is to know how to pick the good kinds.
There are basically five kinds of bottled water: purified water, drinking water, flourinated water, natural source water, and specialty water.
The source water for the first three types-purified water, drinking water, and flourinated water - is municipal, or city water, the same water that comes out of your tap.
In the illustration below, the bottling company will typically filter the water water to remove dirt and harmful chemicals, demineralize it (to remove toxic minerals), and aerate it (to remove any odors by exposing it to air).
Processing of Bottled Water,
Flourinated Water, and Purified Water
Ater having its minerals removed water tastes "flat," so for the two kinds of water that are sold for drinking - drinking water and flourinated water - some minerals are readded to improve taste. For flourinated water only, flouride is also added to the water. As the final step before bottling, all three types are isinfected by ozone or ultraviolet light.
Purified water may also be labeled distilled water, water for distillation uses, de-ionized water, or demineralized water. In addition to having gone through other cleansing processes, each of these labels indicates that the water has had essentially all of its minerals removed and none readded. So in the sense of there being nothing in it but water, this is the purest water. However, the relevant point is not how "pure" it is, but whether or not it is good for you.
