How bad is drinking an old opened bottled of water?

Question

Meaning you open it, drink from it, close it then drink again 1-7 days later??

Answer 1

Not really that bad to be honest.

It would be bad if you opened it like a year ago, and then drank it. But i think that is fine lol. You shouldnt have worried

Answer 2

i dont see why it would be bad for you

the only thing you would need to worry about is the germs from your mouth thats on the cap

but the reason why it shouldnt be bad is because think about where water comes from

... its thousands of years old.. just sitting or is passed through our taps and toilet... and REUSED as drinking water

so we are actually drinking someone elses poo, wee, toilet tissue, menstral blood .. the water has been steralized with water buts its true.

now if water was just sitting there in a bottle.. what happens to it is the hard water would break down , which is very good for plants.if its ok for them, its ok for us

Answer 3

It's bad. The bottles themselves are made from a chemical, when the bottle is left to sit around, the chemical is then released into the water, which you then drink, there is a cancer link with this if you did all the time. In your case, no need to worry about it.

Answer 4

it's not really bad.. there's an urban legend about  that. go to www.urbanlegends.com

or maybe ask doctors so you'll be sure..

Answer 5

If it has been stored at room temp it should be good for a while. It will be good for at least a few days.  A week might be pushing it. But if it's been in the sun or say a hot car, definitely throw it away!

Answer 6

its bad 4 u. u should only drink from it if it waz from the same day.

Answer 7

Yeah, I've heard of something like bacteria grows in the caps of old water bottles or something, dont risk it just drink some tap water

Answer 8

It's OK if you start with very pure water which has no nutrients in it to support bacterial growth.

Answer 9

I doubt it will kill you if you've already done it, but if you have the choice, i wouldn't just to be safe

Answer 10

Answer 11

BAD BAD BAD.IT CAN HARBOR BACTERIA AND MAKE U SICK.BEST TO JUST THROW IT AWAY!

Answer 12

ok water is a very strong solvent, and plastic water bottles have been identified as having carcinogenic properties so the sooner its consumed and recycled the lower the risk of any potential problems minute as they are, also bottled water can be contaminated with phthalate, a toxic chemical that can leach from the plastic into the water in the bottle
