What are the advantages of bottled water over tap water?

Tap water is not cleaner than bottled water. Some tap waters are better than others, depending upon where you live. There are two kinds of bottled water: filtered and distilled. If it does not say distilled, it is filtered. Really good tap water is just about as good as filtered water, while average or bad tap water is not as good as filtered water. Distilled water is cleaner than filtered water and it is the cleanest purest water that there is. (boricua94 improved answer)Also most water regardless is the same. It has no government regulations, In saying that if you really wanted to and had the materials to do this, you could simply find empty plastic bottles, put labels on them and fill them with water. You could make about $1.50 profit max.
