Koshliakova T. Technogenic evolution of cenomanian-callovian groundwater complex chemical composition in Kyiv

Dissertation work contains the results of investigation directed to reveal groundwater chemical composition changes of cenomanian-callovian groundwater complex in Kyiv as a result of man-caused influence. During the research water quality index values of cenomanian-callovian groundwater complex, based on common sanitary coefficients, were determined from the end of the XIX to the beginning of the XXI century. Cenomanian-callovian grounwater complex modern state analysis which includes examination of both hydrodynamic and hydrogeochemistry conditions was executed; geoinformation database model of observable complex potable groundwater chemical composition main components was created. Groundwater chemical composition connection with man-caused factors was determined. Temporal regularities of water quality coefficients changes were defined by using of "kinetic" approach. Estimation of the interfusion process between investigated groundwater complex, atmospheric precipitates and surface water at the quantitative level have been done. The most vulnerable to man-caused influence areas in Kyiv were choosed: minor rivers valleys, the Dnipro river valley and the part of Prydniprovska lowland.
