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

The term used for water that is safe for human consumption is "potable." Potable water meets health standards set by regulatory agencies and is free from harmful contaminants, making it suitable for drinking, cooking, and other domestic uses. Ensuring that water is potable is a critical aspect of public health, as it helps prevent waterborne diseases and ensures the safety of the population.

In contrast, non-potable water refers to sources that are not suitable for drinking without treatment, such as industrial water or water from non-treated sources. Contaminated water contains harmful substances or microorganisms that pose health risks and cannot be safely consumed. Brackish water has higher salinity than freshwater but lower salinity than seawater, making it unsuitable for drinking purposes without treatment.
