Personally I have always had 5 bottles stored for emergencies. The only time alge grows is if I don't have them covered with black plastic to keep the light out. I have used water with green alge in the past, I figure if the alge can grow then the water is good. I would be more concerned if nothing could grow. |
After doing a bit of reading I am not sure how good of an idea that is. I picked up a couple of notes from the net
The International Bottled Water Association (IBWA) advises consumers to store bottled water at room temperature or cooler, out of direct sunlight, and away from solvents and chemicals such as gasoline, paint thinners, household cleaners and dry cleaning chemicals. The U.S. Food and Drug Administration (FDA), which regulates bottled water as a packaged food product, has not established a shelf life for bottled water.
Bottled Water Storage and Growth of Microorganisms
Bottled water often is stored at relatively warm (room) temperatures for extended periods of time, generally with no residual disinfectant contained in it. As noted in the Technical Report (print report only) and shown in Figure 8, several studies have documented that there can be substantial growth of certain bacteria in bottled mineral water during storage, with substantial increases in some cases in the levels of types such as heterotrophic-plate-count-bacteria and Pseudomonas.  Studies also have shown that even when there are relatively low levels of bacteria in water when it is bottled, after one week of storage, total bacteria counts can jump by 1,000-fold or more in mineral water.
Should water be treated before storing it?
If your local water is not treated commercially by a water treatment facility, that is, if your water comes from a public well or other public, non-treated system, follow instructions about water storage provided by your public health agency or water provider. They may recommend treating it with a small amount of liquid household bleach. Still, it is important to change and replace stored water every six months or more frequently.
If your local water comes from a private well or other private source, consult with your local public health agency about recommendations regarding storage of water. Some water sources have contaminants (minerals or parasites) that can not be neutralized by treatment with liquid household chlorine bleach. Only your local public health agency should make recommendations about whether your local water can be safely stored, for how long, and how to treat it.
Can I use bottled water?
I also found this on the little bottles of water you buy. God, is nothing safe?
