If I drink from a bottled water and close it. How long will the leftover water stasy edible?

You shouldnt drink it after a couple days, and don't drink it after a week.

Bacteria from your saliva gets into the water and makes it unhealthy and dirty.

You can sometimes see the bacteria buildup on the bottom of an old waterbottle.

And I dont know if this only occurs in pop bottles, but the plastic makes the water dirty and unhealthy too.

once u open the bottle n finish it whole n the problem is solve

there is no chance of entering of bacteria or fungii.and u ll be save althrough.

coz i do not rely on air so when pollution is more the water becomes automatically impure.

if it is mineral water then also the same problem.

you can drink it overnight, and it wouldn't hurt you. bacteria starts to grow the minute you open it, but it never bothers you and is usually harmless. bottled water doesn't have chlorine or germ-killing elements in it to kill bacteria, but it's all natural and so it should take several days to several weeks for any bacteria to grow there.

if you wanted to save it, you could put it in the fridge and the bacteria will grow at a slower rate.

24 hours MAX..

my sister is a doctor and she has a phd, and she would know. after 24 hours, bacteria starts to grow and you can get sick very easily.

i also learnt this in my home ec class

my teacher stresses it alot, even though im in catering

trust me on this one, you dont want to get sick
