The article examines some fundamental problems of use of groundwater supply sources in the Republic of Kalmykia, including a complicated complex of environmental issues. The research aims to analyze groundwater supply sources located in different hydrogeological zones of the region. It also attempts to overview the history of hydrogeological surveys conducted and provide a summary as for the allocation of available natural drinking waters. Proceeding from the described surveys of all the four hydrogeological zones, the paper concludes that Kalmykia’s hydrogeological structures are complex and specific enough. The vast majority of water-bearing formations are characterized by abrupt changes in water mineralization all throughout the republic. And though the well developed Ergeninsky water-bearing horizon in the Ergeni Upland largely contains good quality waters, it can meet water supply needs of only those residing in the minor western part of the region.
