Some Hydrochemical Features of Water Filtration Sources from under the Left-bank Dumps

Summary The territory of the Left-bank dumps, which is located within the southern industrial zone of the city of Kryvyi Rih, Dnipropetrovsk region, is considered. Its hydrogeological features are determined by the geological and tectonic structure, climatic and geomorphological factors, and man-made impact. Along the perimeter of the dumps, 11 sources of water filtration were installed. The method of comparative-statistical analysis of previously obtained and modern data (hydrogeological, hydrological, engineering-geological and geophysical) studies of the area is applied to identify the degree and nature of technogenically conditioned changes in the state of the hydrogeological structure of the earth’s crust in the area of the Left-bank dumps. Analysis of the location of filtration sources, the chemical composition of water samples taken from them and the analysis of the hydrogeological characteristics of the territory made it possible to establish their origin: with natural runoff (with zones of vertical filtration along faults) - springs No. 1, 11; with a regular runoff of atmospheric precipitation - springs No. 2, 3, 8, 9, 10; with the release of groundwater under the dump-sources No. 4–7, which are presumably associated with an aquifer of Quaternary deposits or a mixed type - aquifers of Quaternary and Neogene deposits.
