Question

How can you tell if water is good by looking at the numbers at the bottom of water bottle?

Answer 1

I would guess not, unless it is clearly a "use by" date.

All bottlers use different coding systems on their products. Some are bottling dates (codified), some are batch numbers, etc. so, unless you can de-code them, you'll be out of luck.
