If bottled water has been under ground for so many million years why does it have a best before date??

Answer 1

Because of the plastic bottle the water is stored in. After time, especially if left or stored in a well lighted area, the plastic breaks down and contaminates the water,

Answer 2

There is still bacteria and other contaminents in the water. Bottling the water keeps all of these in a central location and they are able to multiply and not disperse through the rest of the water. It is a best if used by date, you may notice a stale taste or a different taste after that date. Throw in the break down of the plastic, and the need for everthing used in the US to have a best buy date.

Answer 3

This is impossible to answer, there is not any rest of bottles one million years ago, so the question is not valid. There was not even machines to print the date...

Answer 4

The best before date is for the packaging not the content. It means the packaging is guaranteed not to breakdown before the date stated on it.

Answer 5

The underground streams are moving and being purified by rocks and sand . and has oxygen in it . The bottled water after a time tends to get a stale taste to it . because lack of oxygen

Answer 6

cuz botled water is processed water which has additives in it like sodium and these break up after a certain date that is why they have a expiration date

Answer 7

Because it is in a plastic bottle.

Answer 8

So the supermarket can then make more money selling you a new bottle...

Answer 9

by law they now have to either have a 'best before' or 'use by' date. quite a lot of things you can still use after their expiry dates

Answer 10

Its the markets way of making you throw it away when it hasn't had a half chance at maturing, ignore the best before dates, they aren't "Must be used by" dates............
