Water man-made objects used for balneological purposes (an example of Volga-Ural anticline and the Caspian depression)

Technogenic well-springs discharge occurs mainly at the area of distribution of the Permian sulfate-halogen stratum of the Volga-Ural Anteclise and the Caspian Depression. According to the chemical composition, the water of the "Blue Spring" are sulfate-chloride calcium-sodium with mineralization of 3.8 g/dm3. Water belongs to the XXI group of sulfate-chloride calcium-sodium mineral drinking medicinal-table waters. The spring water can be used in balneology, but with mandatory heating. It contains biologically active substances such as the metasilicic acid of 43 mg/dm3. In the lake, weakly sulphide muds are formed. In the Volgograd region, there are several technogenic spring-wells of hydrogen sulfide and bromine waters. Wells discharge water of the chloride sodium composition of Cl-Na (IIIb) type with mineralization of 3.8 g/dm3, which are a close analog of Mirgorod water, as well as sulfide-sulphate-chloride calcium-sodium SCl-CaNa (IIb) water with mineralization of 6.3 g/dm3. The salt overlying and Triassic sediments are the source of this water. The local population uses this water for balneology purposes. Technogenic spring-wells discharge water for more than 50 years. The ecological consequences of self-influx have not been studied, no significant effects on the environment have been observed, and their effects on the aquifer are unknown. The hydromineral resources of man-made springs and related lakes can be consumed for industrial purposes as well as for population use.
