Yes, stagnant water such as bottled water can indeed become rotten. While the term "rotten" may not be the most accurate way to describe it, bottled water can become contaminated with bacteria and other microorganisms that can make it unsafe to drink.
Bottled water can become contaminated with bacteria and other microorganisms if it is left open or unsealed for a period of time. This allows for the growth of these organisms, which can then make the water unsafe to consume.
No, it is not safe to drink bottled water that has become contaminated with bacteria or other microorganisms. These organisms can cause illness and other health problems if consumed.
Unfortunately, no. Bacteria and other microorganisms are not visible to the naked eye, so you cannot tell if bottled water has become contaminated just by looking at it. It is always best to follow storage guidelines and expiration dates to ensure the safety of your bottled water.
The best way to prevent bottled water from becoming contaminated and potentially "rotten" is to follow proper storage guidelines. This includes keeping the bottle sealed when not in use, storing it in a cool and dark place, and using it before the expiration date. It is also important to properly dispose of any opened or expired bottled water to avoid potential contamination.
