A bottle of water cannot be stored and consumed for too long after opening. That’s how long you have to drink it before you put your health at risk.
We are lucky to live in a country where tap water is clean and safe to drink. But, some people choose to drink bottled water anyway: because they prefer the taste, because it is richer in certain minerals, or to prepare baby bottles for example. Even if tap water is generally perfectly suited to feeding infants and babies. But when we talk about water, many people are unaware that it can also expire, like other drinks, and foods that we consume, as our colleagues from Marmiton.org. When you buy a bottle, or a pack of bottles of spring water or mineral water, an expiry date, or optimal use limit (DLUO) is indicated: it is 2 years old. however, when the bottle is opened, it’s a whole different story.
After opening, your bottle of water must be drunk within 24 and 48 hours. The main risk is that of seeing grow microorganisms in water. And in doing so put your health at risk by consuming water from this bottle. This is a phenomenon that can also be accelerated if you drink directly from the neck of your water bottle. For this same reason, it is highly inadvisable to keep a plastic bottle, even if you want to reduce the ecological impact of your plastic bottle, and to use it again. As it is no longer sealed, bacteria can proliferate there.

Tap water also expires
Be careful, thetap water also expires and should not be drunk too long after being drawn. Even more so when it is kept in a gourd or a carafe, objects which often escape a meticulous daily or even weekly washing with white vinegar. For example, avoid drinking from this decanter in the refrigerator when you return home after 10 days of vacation.
Also, be aware that it is better to run the water from your tap for a few seconds in the sink before putting it in a glass or carafe. This is important to evacuate the water that has stagnated in the pipes.
