Why does bottled water have an expiration date?

Maybe the light and oxygen acting on the minerals are different in the bottle than in nature and over time it could make a difference? I dunno just a guess.

Same reason it has the nutrition content listed even though everything is zero. It's a government requirement. That's my guess at least.

GreenDoberman is correct, for every product you have to list by law what does it has, the nutritional information, facts of whatever it is called, the date that it was made (in this case bottled) and an expiration date or at least an estimate

The bottled water I am drinking today has an expiration date of 05/06. Now If the government has FORCED this company to put an Expiration date on a bottle that has listed a "0" for ALL contents--then exactly what does the government hope to help the consumer with here?
If I drink the water in June of 06---What are the risks? (According to the government of course)

It might be bottled water, but its not something completely sterile and pure, even medical grade stuff (serum and the like) have expiration dates

Esentially you can't have 100% pure anything, there may be a few bacteria left that are completely harmless because their % in the water is really small, but since the bottle is closed eventually they might reproduce and end up being harmful

Specially because most bottles are transparent and the light that goes through allows energy to get through the bottle, I supose there might be some kind of liquen in there that might use the light to grow

"0" for ALL contents"

the 0 there is a zero for laboratory effects, it doesnt mean that it absolutely positively has NOTHING in it, obviously its almost 99.9999999% H2O and it has traces (very small quantities) of many other things

example, sea water has gold in it, problem is the percentaje is like 0.000000000001% so the cost of extracting it far outweights the profit

I SUPOSE that the purpose of listing zero of CERTAIN chemicals such as Sodium is to help the person that is trying to follow a diet low in sodium to make sure its alright to drink/eat that.

The water that is the this bottle is very clear and that's the main reason that I drink it. (Yes no sodium as well). But the tap water (city water) here may taste all-right---it looks like it has something in it.
It may be psychological (miss-spelled) but I feel better drinking this water than that out of my faucet.

I'd feel comfortable enough drinking it 5 years later, 20 years later I'd replace it. In dire circumstances it would be feasible to drink your own urine.

I'd suggest rotating your stock ( FIFO). First in first out.

It shouldn't be a huge problem ! I would drink 20 year-old bottled water over urine though !
