1 Answer/Comment
Water quality is determined by assessing three classes of attributes: biological, chemical, and physical. Some attributes are considered of primary importance to the quality of drinking water, while others are of secondary importance.

Primary drinking water standards regulate organic and inorganic chemicals, microbial pathogens, and radioactive elements that may affect the safety of drinking water.

Secondary drinking water standards regulate chloride, color, copper, corrosivity, foaming agents, iron, manganese, odor, pH, sulfates, total dissolved solids, and zinc, all of which may affect qualities of drinking water like taste, odor, color, and appearance.
