Abstract: The paper discusses the application of entropy analysis to assess the distribution of pollutants in the water sections of the river Tom from the city of Mezhdurechensk to the urban-type settlement of Yashkino. In the entropy method, impurity distributions in water samples are replaced by distributions of the amount of in-formation about the concentrations of ingredients, as a result of which the data are displayed in phase space. Displaying indicators of water pollution in these areas on the phase plane of inversions allows us to determine the territorial clusters of substances: K1 (nitrogen ammonium, nitrogen nitrate, nitrogen nitrite), K2 (hydrocar-bonates, calcium, mineralization, chlorides), K3 (petroleum products, phenols, resins and asphaltenes), K4 - dangerous to humans (aluminum, silicon, thiocyanates, cyanides, nitrite nitrogen, cadmium, molybdenum, lead, mercury, hexachlorane). The creation of clusters makes it possible to identify a group of ingredients characteristic of a particular water management sector, which allows reliable identification of pollution sources. In the work, it is established that the distribution of ingredients depends on the date of sampling and on the volumes of the impacting sources of pollution. The water management areas of the Tom River were established, containing the maximum number of ingredients of the corresponding
