Once the water stops moving it becomes stagnant.
If you got a cupful of stream water and left it for a week, untouched, in the cup, you would find bits of green slime growing in it.
Nothing is 100% pure.

Because the chemicals in the plastic bottle begin to break down (although microscopically tiny) thus would alter the water over time.

Government legislation states everything has to have an expiration date for safety. Blame government.
