Integrated uranium-isotopic and microhydrochemical studies were used to develop an indicator model of formation and circulation of drinking groundwater of Neogene-Quaternary deposit and to assess their current ecological state. The paths of subsurface flows of infiltration recharge are identified and traced, and the zones of deep-water inflow are identified and delimited. The total pollution index of groundwater from Neogene-Quaternary aquifer system was found to far in excess of the acceptable level because of an elevated concentrations of iron, manganese, and phosphorus of anthropogenic and deep-seated origin. © 2014, Pleiades Publishing, Ltd.

The results of multidisciplinary uranium-isotopic and microelement hydrochemical studies were used to establish that mineral waters in the eastern part of the Cheboksary reservoir have formed from mixing of strata waters of Tatarskie deposits with a deep water, entering through fractured-weakened zones of deep faults of the Gor'kii-Kil'mezskaya lineament zone. © 2010 Pleiades Publishing, Ltd.
