Fresh groundwater resources in the Republic of Bashkortostan are distributed extremely unevenly. Its eastern regions are particularly water-deficient. An assessment of the geochemistry of fractured groundwater in the Zilair Basin (the Ural hydrogeological folded region, the Southern Urals), helps to identify additional sources of fresh groundwater to meet the needs of the republic’s population. All groundwater in this area is fresh. Their salinity ranges from 0.04 to 0.9 g/dm3. Their total hardness ranges from 0.2 to 3.39 mmol/dm3. Groundwater of the magnesium-bicarbonate and magnesium-calcium-bicarbonate types, associated with ultramafic and mafic rocks, is extremely rare in the Southern Urals. Due to their low mineralization (up to 1 g/dm3) and high magnesium content, which is essential for the normal functioning of the human body, they can be used as table mineral waters.
