Why does water expire ?

Question

H20

Answer 1

I think that "natural" water does not expire (water from a spring); but I think that water in a bottle expires because it does not have the same time of natural flowing effect as the water in the natural spring does.

Answer 2

Water does not expire. Bottled water is labeled with an expiration date, because authorities feel that it should be. Producers of bottled water do not want to be called irresponsible, so they put an expiration date on their bottles. You might try calling the 1-800 number on bottled water labels and asking what is the significance of the expiration date. That will give them pause.

Answer 3

In most countries bottled water is considered to be a pharmaceutical product. The statutory labelling requirements demand that a date up to which the contents will remain bacteria free has to be declared. Fairly stiff penalties are levied if this is violated.

The water does not expire. The sterility does, or rather, can.

Answer 4

Water is known as the universal solvent it will pretty much absorb any impurities found in the bottle while manufactured. During filtration ozone is added to the water. If too much ozone is added the plastic from the bottle will begin to deteriorate into the drink. If too little ozone is added bacteria will be more apt to grow. But since this is pretaining to chemistry I would focus more on the part the water is a very good solvent.
