This article deals with new Czech Standard 75 7221 Water quality – Classification of surface water quality [1] and replaces the previous 19 years old standard [2]. It was necessary to take into account actual demands of the surface water protection from two points of view: pollution indicator selection and current environmental quality standards. The range of pollution indicators and limit values of water classification were revised.
