Water quality of the rivers of the Baikal natural territory by hydrochemical indicators

The generalized results of regular observations of the water quality of the rivers of the Baikal natural territory by hydrochemical indicators, carried out in 2019.

Classification of the degree of water pollution is a conditional division of the entire range of composition and properties of natural water under conditions of anthropogenic impact at different intervals with a gradual transition from "conditionally clean" to "extremely dirty" by the values ​​of the combinatorial index of water pollution, taking into account a number of additional factors.

The water quality class was calculated according to the observations of the State Hydraulic Station of Roshydromet in 2019 using RD 52.24.643-2002 'Guidelines. «Method for a comprehensive assessment of the degree of pollution of surface waters by hydrochemical indicators».
