The article presents the results of research on the hydrological and hydrochemical regimes of the Chirchik river. This research is devoted to a scientific or practical problem, such as insufficient effectiveness of existing monitoring. Factual data on the concentration of pollutants, most often exceeding the maximum permissible concentrations, are presented. An analysis of the study of the spatial distribution of pollutants (PV) along the river length is presented, which allows for the identification of the most polluted areas. The dependence of the concentration of pollutants on the water content of the year was considered.
