The article describes study of the hydrochemistry of Taldykol lake system, consisting of the Big and Small Taldykol lakes, in the city of Nur-Sultan. The aim of the work is to assess the anthropogenic impact on the ecosystem of steppe wetlands located in the center of the developing capital. Sampling was carried out from 8 sites of the lake system in autumn 2020. The results of hydrochemical analysis of water samples made it possible to assess the level of chemical pollution and anthropogenic impact on the ecosystem, which, due to rapid urbanization, the lakes have been exposed to for decades. Now, due to the artificial fragmentation of lakes, the surface communication between the sites is disrupted, as evidenced by the different composition of pollutants in water bodies. Nevertheless, to draw up a complete picture and assess the anthropogenic impact on the Taldykol lake ecosystem, it is necessary to consider the results of a comprehensive study of lakes, which includes a number of additional works.
