water purity
How clean H2O
Water purity is the degree to which water is free from contaminants—chemicals, microorganisms, sediments, or dissolved solids.
The term appears in discussions of drinking water safety, environmental standards, and industrial processes: The EPA sets water purity standards for municipal systems.
Higher purity means fewer impurities; distilled water represents near-total purity.
