The conductivity of water is measured in Siemens per meter (S/m). Sea-water is typically 5 S/m, [5] drinking water is typically in the range of 5-50 mS/m, while highly purified water can be as low as 5.5 μS/m (0.055 μS/cm), a ratio of about 1,000,000:1,000:1. Purified water is used in the pharmaceutical industry.
Distilled water. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water .

Drinking water and staying hydrated is an essential part of being healthy, but picking up any brand of bottled water to reach your suggested daily intake might not be the smartest move.
Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2·nH2O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic and deliquescent, it is used as a desiccant. [ 10 ]

Fluoridation does not affect the appearance, taste, or smell of drinking water.[1] It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate. Sodium fluoride(NaF) was the first compound used and is the reference standard.[35]
