Answer 5

Answer 6

So you can buy it cheaply when it goes out of date.

Answer 7

Absolutely no idea. Must be a sales ploy

Answer 8

lol, Dave some of the answers are priceless, love it...

To answer your question, there is always the presence of tiny algae, spores and bacteria in spring water, which react with sunlight, they grow and continue to grow over time, if the water is aerated then the problem is lessened.

But if the bottle remains closed then the water becomes saturated

So a date is set as a safe margin

Answer 9

So true ...... it water itself has parasites in it that can't be filtered out ....... it is safe for a short amount of time but they do grow unsafe after awhile ...... as well as the water being in a plastic bottle which allows bacteria and heat to infultrate the plastic bottle ....... all that is why bottled water does have expiration dates ...... = )

Answer 10

Good question! Might be something to do with the plastic bottles, or it's just a scam so that we buy more : )
