No water is entirely pure. Most water has minor impurities like dissolved salts of sodium and calcium; tap water in most countries has additional chlorides and fluorides to help kill off bacteria in the water. Some countries deliberately add forms of medication, e.g. in the UK, flouride is added to help contain dental caries (tooth decay). This is in addition to any chemicals needed to make water drinkable. My original answer, which was substantially correct, was removed - why? I am told by Wikianswers that it is polite to add to answers or comment on them, not delete them.
