Изменение гидрогеохимических условий при эксплуатации Академического месторождения

The results of research of hydrogeochemistry of groundwater deposit which is used by the big apartment borough of Tomsk city for water-supply is presented. The information about changing of hydrogeochemical measures during use of this deposit of groundwater is given. Steady-state increasing of SO42-, Ca2+ and Mg2+ in time and decreasing of dissolved concentrations of Fe ion at one time is established. The aeration of the interior of the Earth in conditions of broken hydrodynamic regime and long-term use is the main cause of this changing. The changing of chemical composition of groundwater is accompanied by development of secondary minerals on processing equipment of intake wells. The sediments represent polymineral mixture of oxide ferriferous, phosphate, carbonate, silica-alumina mineral phases.
