What defines potable water?

Potable water is defined as water that is safe for human consumption. This means it meets specific health and safety standards that ensure it does not contain contaminants harmful to health. The characteristics of potable water include being free from pathogens, chemicals, and other substances that could pose health risks. It is treated and tested to ensure it meets the necessary quality criteria for drinking, cooking, and other domestic purposes.

In contrast, water suitable for irrigation, water that is not safe to drink, and water with high mineral content do not fulfill the criteria for being classified as potable. Water for irrigation may contain fertilizers or pesticides, making it unfit for human consumption. Water deemed unsafe to drink could carry harmful bacteria or toxins, while high mineral content does not necessarily imply safety, as excessive minerals can also be detrimental to health. Thus, the definition of potable water is pivotal in ensuring public health and safety standards in water supply systems.
