why is there an expiration date on bottled water?

Question

has anyone ever noticed that when you happen to drink bottled water(depending on the kind), that there is always an expiration date

Answer 1

Water can go rancid. I used to store water in my basement in case of a long power outage. Then one year I went down and pulled out the bottles that were past expiration. After opening them up, I knew exactly why there is an expiration, they smelled like stagnant pond water. NASTY.

Answer 2

Because bacteria will form after the expiration date. Do you want to chance that drink? Not me.

Answer 3

Answer 4

because after the expiration date there will be no more oxygen in the water and it will become flat

Answer 5

Because if you leave it too long, it will god bad because bottled water is usually natural water. And natural means it can not be kept forever.

Answer 6
