The model for mixing wastewater and river water was built using Selector software. Chemical analysis of highly mineralized wastewater from the Usolye industrial zone which is one of the main pollutants of the Angara river, and river water in the area before and after exposure to technogenic sources was carried out. Forms of migration of Al, Cu, Zn, As, Cd, Pb, Hg in the geochemical systems and their transformations have been identified. Due to a high self-cleaning ability of the Angara river, concentrations of toxic elements can decrease to the background values. Technogenic pollution changes forms of these elements in the aquatic environment and increases the environmental hazard to the aquatic ecosystem.
