Abstract

The results of the research devoted to the geochemistry of natural sources of springs on the territory of the Pre-Ural Artesian Basin are relevant, since the springs are understudied and are not classified according to their chemical composition and purpose. The southern area of the Pre-Ural Artesian Basin with salt-gypsum tectonics was studied. There are many springs with various chemical compositions there. The prevailing salinity level of spring waters varies from 197 to 941 mg/l, with total hardness of 1.33-5.5 mg-eq/ l, and with good quality drinking water. The goal was achieved. The hydrogeological conditions and hydrogeochemical characteristics of the source waters were studied. Analogues of mineral waters of the group without "specific" components and properties of the Krainsky and Varninsky types with the salinity level from 1.2-3.36 g/dm3 are found by comparative analysis: sulfate, bicarbonatesulfate, sulfate-bicarbonate calcium, magnesium-calcium waters. Springs with high salinity sodium chloride leaching waters with 124 g/dm3 for balneotherapy are associated with salt dome structures. A certificate on the exact possible therapeutic properties of spring mineral waters can be issued by the Institutes of Health Research Study after research.
