The article deals with the hydroecological situation on the Seversky Donets River within the Belgorod region. A hydrochemical analysis is being carried out in terms of pollution with the main biogenic elements (nitrogen and phosphorus) according to the monitoring data of Roshydromet. There is a differentiated dynamics of the content of pollutants with individual peak fluctuations in the studied sections. There is an increasing jump trend for ammonium, nitrites and phosphates. Correlation analysis of indicators of the content of chemical components in the Seversky Donets River makes it possible to identify a conditional area with a similar ecological situation and general processes of nutrient intake in relation to the studied sections No. 2 and No. 3, which is associated with the proximity of the city of Belgorod and an increase in residential load. At the same time, the correlation coefficients in the two sections have a strong relationship from 0,75 to 0,9. This makes it possible to conditionally divide the catchment area of the Seversky Donets River into 2 separate areas with varying degrees of anthropogenic impact: the upper reaches of the river (Prokhorovsky, Yakovlevsky districts) and the riverbed in the city of Belgorod and the southern part of the Belgorod region up to the border with Ukraine.
