A Newspaper Article today (UK) reports on the state of drinking water in England. There has been a report released by the Drinking Water Inspectorate (official watchdog) saying our drinking water is passing their tests at a high standard. It also says that bottled water is NOT BETTER (not necessarily worse)than what comes out of our taps, but costs about 1,000 times as much.
A Guardian WaterFact sheet - BLICKY.
The newspaper report (whichever paper) mentions that bottled water has a use-by date of 2 years, but could be stood in storage for an indeterminate time before the label is put on, so may be MUCH older.

I reckon if the water in the bottle doesn't absorb anything out of the bottle in two years of residence, putting FRESH water in which stays there less than 24 hours isn't going to shift ANYTHING from the plastic.
QUACK.
