but,

It is suggested that you not store water for long periods (greater than 1 year) Most bottled waters have no expiration date, and while it is unlikely that substantial amounts of microbial growth would occur, it makes no sense to purchase bottled water for it's purity and then allow algae to grow in it. The U.S. Food and Drug Administration (which regulates bottled water) has not set any limitation to the shelf life of bottled water. You may have noticed that most bottled water containers sold have a two-year expiration date. That is only used for stock rotation purposes. It does not mean the water will go bad if stored (properly) longer.

In the United States bottled water's shelf life is date stamped for two years. It should be stored in a dark, cool, dry area away from any solvents or chemicals.
