| Summary: | The results of hydrogeochemical monitoring of the Sarmat-Meotis-Pontic sediments aquifer complex of the North Sivash artesian basin have been analyzed. The analysis based on a routine observations for 16 producing wells. The observations were made in the period from 2014 to 2017 years. A correlation and regression analysis has been made for definition of dependencies between changes in the concentrations of the normalized components. The results obtained allow us to evaluate the main factors of formation of the chemical composition of groundwater. At the present stage, metamorphosed waters are pulled up from the lower strata of the complex, that leads to an increase in the amount of mineralization. The formation of sulphate waters is primarily associated with the peculiarities of the geological structure, namely, the high gypsum content of quaternary deposits and the presence of hydraulic connection with the overlying aquifers. One of the reasons for the formation of sulphate waters is the anthropogenic impact associated with the close location of the acid accumulator containing sulfur tailing. The results obtained allow us to proceed to the next stage of the survey — the creation of a natural hydrogeological model of the research area and the carrying of the thermodynamic modeling. |
