Abstract
The Ural River is the main source of water supply for Atyrau Region, providing drinking water not only to the city of Atyrau but also to settlements in the Inder, Makhambet, and Makat districts. Therefore, its quality and hydrological regime are of strategic importance. In achieving SDG targets 6.1 and 6.2, related to access to safe drinking water and sanitation in Kazakhstan’s rural areas, the hydrochemical regime of the Ural River and the influence of the hydrochemical water regime of the North-Eastern Caspian Sea play a crucial role. This article presents hydro-physical and hydrochemical indicators obtained during field geo-ecological studies. Based on the chemical analysis of water samples from key sites, the current state and hydrochemical regime of surface waters are described.
