The West Kazakhstan region of the Republic of Kazakhstan occupies an area equal to 151,339 km(2). In the land structure, 69.7% of the area is occupied by agricultural land. The region has great prospects for the development of the livestock industry. However, uneven territorial availability of water resources is a limiting factor in increasing the amount of livestock in the region. The purpose of the study is to monitor underground water sources in the West Kazakhstan region of the Republic of Kazakhstan to assess the zonality of their placement. The boundaries of natural and climatic zones on the territory of the region were laid over the publicly available cartographic materials on the hydrological data of the distribution of groundwater. The water source monitoring was carried out by examining their actual condition in specific geographical locations, including using remote sensing methods, with a further determination of quantitative and qualitative parameters. The paper considers the state and problems of water supply at the pastures in the natural and climatic zones of the West Kazakhstan region. The region is characterized by the use of groundwater in the water supply of pasture lands. Underground springs have a certain zonality in their location, manifest themselves at different depths corresponding to different geological horizons, and differ in a wide variation of water mineralization. In the dry steppe zone, it is recommended to use the aquiferous mid-upper quaternary alluvial, aquiferous upper Pliocene Akchagyl, and aquiferous upper cretaceous Maastricht horizons. The water sources used have depths of up to 120 meters, and the mineralization varies from 0.2 to 9.1 g/dm(3). In the semi-desert zone, the upper-quaternary aquiferous marine Khvalynsky and the lower-middle-quaternary aquiferous marine Baku-Khazar horizons are recommended. The water sources used have depths of up to 90 meters, and the mineralization varies from 0.2 to 11.8 g/dm(3). The semi-desert zone is characterized by the use of springs with depths up to 80 meters. The mineralization of water in the permeable modern Aeolian horizon is more often low (0.11-0.9 g/dm(3)) and rarely brackish (1.1-9.36 g/dm(3)).
