Detailed Explanation
Potable water is defined as water that is safe and suitable for human consumption. It must meet certain health standards to ensure that it does not pose any risk of harm to those who drink it. This definition is critical because not all water available in nature is drinkable; some may contain harmful contaminants or pathogens that can lead to illness.
Examples & Analogies
Imagine you have two glasses of water: one from a clean, treated tap, and another from a muddy puddle. The water from the tap is safe and potable, while the muddy puddle water is not safe to drink. Just like you wouldn't drink muddy water, humans need to ensure they consume only potable water to stay healthy.

Detailed Explanation
Potable water must have certain qualities to ensure its safety for drinking. Firstly, it should be clear and colorless, which indicates that it is free from visible impurities.
