What characterizes potable water?

Potable water is specifically characterized as water that is safe and pure enough for humans to drink. This type of water meets health and safety standards set by regulatory bodies, ensuring it is free from harmful contaminants and pathogens that could pose health risks.

The other options do not align with the definition of potable water. While irrigation water is crucial for agriculture, it is not necessarily safe for human consumption. The source of potable water can vary, including surface water sources and groundwater, but simply pumping water from underground wells does not guarantee its potability, as it must still be treated and tested for safety. Lastly, water designated for industrial use may contain chemicals or contaminants that make it unsafe for drinking, thus it cannot be classified as potable.
