Abstract
The hydrogeofiltration structure and water balance of the Dombrovsky quarry depression cone were analyzed. The radius of the quarry depression was about 1.5 km. Environmental threats are following the modern transformation of the quarry from a drainage system into a source of aquifer feeding by highly mineralized water. The assessment of gravel and pebble drinking water horizon pollution and mineralization of Limnitsa river, which is a regional local drainage, is carried out. The value of salts annually transported into the gravel and pebble aquifer is assessed to 648 kt. During nearest 2.5 years the front of highly mineralized groundwater will discharge to Limnitsa river that provide the growth of surface water mineralization to 0,81 g/l. The liquid body of Dombrovsky quarry is came to quasi-equilibrium water balance and hydrochemical state with groundwater aquifer that determines the additional threat of drinking water source pollution.
