I guess it depends on who you ask, where you live, and where the bottled water comes from. But here's a question. What would you say the price of water is per gallon.

Twice as expensive as gasoline, 3 times the price of milk, and 10,000 times more expensive than tap water. Is it worth it?
Do we buy it NO. NEVER. Truth be told though we do use a reverse osmosis filter for our drinking water.

Ironically, public concern about tap water quality is at least partly responsible for the growth in bottled water sales, which have tripled in the past 10 years. This bonanza is also fueled by marketing designed to convince the public of bottled water's purity and safety, marketing so successful that people spend from 240 to over 10,000 times more per gallon for bottled water than they typically do for tap water.

In fact, about one-fourth of bottled water is actually bottled tap water, according to government and industry estimates (some estimates go as high as 40 percent). And FDA rules allow bottlers to call their product "spring water" even though it may be brought to the surface using a pumped well, and it may be treated with chemicals. But the actual source of water is not always made clear -- some bottled water marketing is misleading, implying the water comes from pristine sources when it does not. In 1995, the FDA issued labeling rules to prevent misleading claims, but while the rules do prohibit some of the most deceptive labeling practices, they have not eliminated the problem.
