Abstract

This article provides an assessment of the quality of surface waters of the Irtis River within the city of Ust-Kamenogorsk based on hydrochemical indicators. The dynamics of the main hydrochemical indicators (ionic composition, mineralization, hardness, biogenic substances, BOD, COD) for 2024, covering all seasons, is presented. The spatial and temporal characteristics of the distribution of hydrochemical indicators of surface waters of the Irtis River within the city of Ust-Kamenogorsk are established, which were determined by the level of anthropogenic load at each specific research point.

As a result of the conducted studies to assess the quality of surface waters of the Irtysh River within the city of Ust-Kamenogorsk, it was established:

- by the value of the hydrogen index, slightly alkaline, low-mineralized, hydrocarbonate class, calcium group. The total salinity during high water is 113-211 mg/dm3, in summer and autumn it is 136-173 mg/dm3, in winter it is 148-156 mg/dm3. The water hardness ranges from 1.20 - 2.64 mg·eq/l, which makes it possible to classify the surface waters of the Yertis River as "soft";

- the concentration of biogenic substances, except for iron, corresponds to the standard indicators and does not exceed the maximum permissible values ​​for water bodies for fishery purposes. In addition, the regulatory value of fisheries for iron (0.1 mg/ dm3) was slightly exceeded;

- the total content of heavy metals, in particular zinc and manganese, slightly exceeds the maximum values ​​​​for fishery water bodies (0.01 mg/dm3).

water quality, chemical composition of water, biogenic substances, main cations, main ions, mineralization, heavy metals, quality class.
