What defines potable water?

Potable water is defined as water that is safe for human consumption. This means that it meets health standards and is free from harmful contaminants and pathogens, allowing people to drink it without adverse health effects. The treatment and testing of potable water ensure that it is suitable for consumption and complies with government guidelines and regulations concerning water quality.

In contrast, the other options describe water usages that do not pertain to safety for human consumption. For example, water that is unfit for consumption indicates that it contains harmful substances, while water used only in agriculture does not imply that it is safe for human drinking. Lastly, water used for recreational purposes may not necessarily meet the safety standards required for drinking. Understanding these distinctions highlights the crucial importance of potable water for public health and safety.
