Features of Formation of the Chemical Composition of Natural Waters of the Solikamsk Region

Solikamsk region belongs to the territory of increased environmental attention due to the high concentration of industrial enterprises. Construction of the Polovodovskiy potash plant with a salt dump and a brine storage facili-ty is planned on the territory of the study. Waste disposal facilities of enterprises are potential sources of pollu-tion of the surface and underground hydrosphere. Therefore, the purpose of the work is to assess the current state of surface and groundwater and forecast their possible changes under the influence of the planned anthropogenic load. The work is based on the results of a study of the state of the environment of natural waters of the catch-ment areas of the middle reaches of the river Usolka and the southern part of the Borovaya River. The authors analyzed the data for 2016-2021.
