The purpose of the study is to assess the water quality of the Don river basin within the Voronezh urban agglomeration. Methods and materials. The article presents the results of a chemical analysis of the state of three water-courses flowing within a 40-km zone of influence of a large industrially developed city of Voronezh, under conditions of an increased technogenic load and forming the hydrographic framework of the Don river system: the Don River (the main watercourse) and its two left tributaries – the Voronezh and Usman' Rivers. Chemical analysis of priority pollutants in river water samples was carried out using organoleptic, titrimetric, potentiometric, conductometric and colorimetric methods of analysis. Results. The increased anthropogenic and recreational load within the Voronezh urban agglomeration has a negative impact on the water quality of the Don river basin, which can be assessed in the form of the following water quality classes: Don River is “dirty”; Voronezh River is “moderately polluted”; Usman' River is “polluted”.
