Environmental monitoring of Lake Baikal

Water quality of rivers of the Baikal Natural Territory

Water quality of rivers of the BNT according to hydrochemical indicators

The classification of water pollution rate is represented by the conventional division of the whole range of composition and properties of natural waters under conditions of anthropogenic impact by different intervals, with a gradual transition from “conditionally clean” to “extremely dirty” in values of combinatorial water pollution index with consideration of a number of additional factors.

The map shows the colour of circular pictograms, which meets the data of the integral assessment of water pollution degree in 2013. The water quality classes used for the assessment are shown in the map legend.

If you hove over the line of observation, you can see the information on the water pollution in 2013 for certain indicators and the pollution class of the integrated assessment in 2013.

Class of water quality was calculated according to the observations of the State monitoring network of Roshydromet in 2013 with the use of RD (Regulatory document) 52.24.643-2002 “Methodological guidelines. Method of integrated assessment of the surface water pollution degree according to hydrochemical indicators”.
