Purpose The paper aims to evaluate the environmental impact of Levoberezhnyi dumps and Voikovo and Obiedinennoe tail-end depositaries located at the south outskirts of Kryvyi Rih; to study the sedimentary cover tectonic structure and pre-Cambrian base features, sewage chemical composition alteration to be utilized under natural conditions, geo­logical features of the location designed for mine drainage and containment of dangerous engineering and geological developments due to filtration losses and atmospheric waters accumulation in the dumps.
Methodology We used a complex analysis of the geophysical research results, hydrologic and hydrogeology condi­tions and engineering and geological developments in Levoberezhnye dumps and Voikovo and Obiedinennoe tail-end depositaries locations to determine their impact on the environment.
Findings We have revealed 6 problematic sources, displays and seats of negative and phenomena activation: filtration substitution with signs of Voikovo and Obiedinennoe tail-end depositaries dam dump gutter; descending filtration of contaminated water in the former from the surface water level and carbonate deposits of neogene situated below as the result of breaking the protection screen that accelerates the karst formation; at least 3 sources of contaminated water open flows of Levoberezhnye foot slope dumps; a marshy ravine situated to the north from Novoselovka settle­ment that takes the dumps contaminated surface flows; soil salinization and contamination within the radius of 1 km around the dumps as a result of highly mineralized subsoil waters spreading and vaporization, and salts concentration as well as of wind erosion; activation of karst formation, suffusion and surface erosion on the steep slopes area in Rudnichnoe, Novopetrovka, Novoselovka, Inhulets settlements and small town of Shyrokoie.
Practical value/ implications We have suggested measures for drainage and purification; we have also grounded the possibility of mine waters discharging into the water leveling in cracked crystalline rocks of pre- Cambrian period; drainage parameters have been calculated. The dynamics of hydrologic, hydro-geological, engineering, and geologic conditions supports the necessity of carrying out geo-ecologic monitoring in order to react promptly to new types of dangerous processes and phenomena.
