Bromine and Iodine-bromine Mineral Waters in the Voronezh Region

Abstract

The purpose of this study is to assess the hydrogeochemical and geoecological state of ground mineral waters in Voronezh Oblast, to estimate reserves and the possibility of their use. Materials and methods. The work is based on the results of field and laboratory studies (analysis of geological, hydrogeological and geoecological parameters). Chemical analyses of water samples were performed and processed according to the methods developed in the laboratories of the Central Research Institute of Balneology and Physiotherapy, Voronezhhydrogeoecology, the Voronezh State Agrarian University named after Emperor Peter I and the Voronezh State University. Using the Piper's diagram, the water types of the studied sources were identified and presented. The analysis of specific flow rates helped to estimate the available reserves. Results and discussion. Bromine and iodine-bromine mineral waters can be used for therapeutic purposes. The chemical composition of water with a predominance of high content of chlorides, sodium-potassium and calcium does not correspond to the lithological rocks of the aquifer (limestone and gabbro). Chlorides are residual salts from ancient marine basins. The water reserves are estimated to be about 976 m3/day. And they are practically not subject to technogenic pollution, because they are located at great depths. Conclusion. Bromine and iodine-bromine mineral waters are rare in nature. In this connection it is necessary to pay attention to the unique nature of the natural potential of Voronezh region, within the limits of which there are deposits of bromine and iodine-bromine mineral waters.
