| Abstract: | A classification of surface waters of humid zone by its humus content, alkalinity, and trophic status has been developed basing on the acid-base equilibrium of those waters, governed by two systems: humus and carbonate, which enabled the geochemical classes of water to be established more objectively than by expert systems. An integrated estimate of natural water quality is given with the use of quality points by individual characteristics. For water bodies subject to anthropogenic impact, the degree of their pollution is given in accordance with water pollution index, which is calculated by the main standardized components, taking into account their geochemical background level and the values of MAC for water bodies used for fishery. |
