Abstract
The publication is devoted to the study of groundwaters in the Saksagansk-Sursk ore district of the Dnipropetrovsk region, which are used to ensure the economic and drinking needs of the local population. The chemical composition of underground waters was studied, an assessment of their quality and suitability for potable use was made, the range of risks for the health of local residents-consumers of water was outlined, and the rationale for possible reasons for changes in their chemical composition during 42 years of operation (from 1978 to 2020) was provided. During the research, the authors found signs of metamorphization of the chemical composition of groundwater. A preliminary conclusion was obtained that the ecological-hydrogeochemical conditions of the studied groundwater are primarily determined by: insignificant occurrences of water-bearing rocks (up to their emergence to the surface), close hydraulic connection with surface waters and adjacent aquifers, weak protection against surface pollution due to the lack of regionally sustained confining bed in its roof, the chemical composition of water-bearing rocks, as well as the tectonic conditions of the territory.
