What is the term for water that is safe for human consumption?

Potable water refers to water that is safe for human consumption. It meets specific safety standards laid out by health regulations, which ensure it is free from harmful contaminants, pathogens, and substances that could adversely affect health. This type of water is suitable not only for drinking but also for cooking and food preparation.

In contrast, nonpotable water is unsafe for consumption and might be used for irrigation or industrial purposes. Contaminated water contains harmful substances or pathogens, making it hazardous for human health. Deionized water is treated to remove mineral ions but does not necessarily meet the health standards required for potable water, particularly regarding microbial safety. Thus, potable water is essential for public health and is a vital aspect of sanitation practices.
