As both tap water and bottled spring water are safe to drink, which is better is a matter of personal choice. Although there are some who claim that drinking spring water is better for an individual, this has not been scientifically proven.
Some bottled spring waters contain natural minerals, such as sodium, which tap water does not. Much of the bottled water sold is designed to look like spring water. Only water from a recognized spring can be described as spring water. About 25 percent of bottled water is tap water that has been filtered. After filtering minerals, such as sodium and calcium, are added.
