Evaluation of drinking water according to geochemical composition of its salt deposition

Abstract

Salt depositions of drinking water in three regions – Irkutsk, Tomsk and Cheljabinsk- were examined and analyzed. The total amount of analyzed samples included 416 items. The element composition analysis showed inhertance of the water element composition in salt depositions. The content level of macro- and micro elements in the scale depends on the geochemical peculiarities of that or another area. Natural (deposits, ore occurrences) and anthropogenic (industrial enterprises, urbanization) sources strongly effect the composition formation, It was determined that the element composition of depth drinking water sources included only natural element source inflow, while, in the case of surface drinking water sources, it is the result of natural and anthropogenic source impact. Obtained salt deposition data can be correlated with the data from other deposited environments.
