Abstract
The article presents an analysis of the qualitative composition of the surface water body, namely the Seim River in Chernihiv and Sumy regions, to determine changes in its ecological status. A statistical and systematic analysis of changes in the ecological state according to the interactive map "Monitoring and environmental assessment of water resources of Ukraine" of the State Agency of Water Resources of Ukraine in the period from January 2012 to December 2020. The content of normative indicators was also analyzed: polyphosphates, ammonium, nitrates and nitrites, phosphates and sulfates. Data on control of water intake from 4 posts within the Seim River were studied. In the future, the results of the study can be used in the development and implementation of a reliable and effective model for forecasting the ecological status of the Seim River.
