Abstract: The paper discusses the peculiarities of hydrological and hydrochemical regime of ground water in shallow wells and boreholes in moraine soils of active karst zone. It was determined that the fluctuations in water levels in boreholes and wells have the same tendencies: water was closestto the ground surface when the air temperature was increasing in the cold period (November-March) and decreasing in the warm period (April October) of the year. Chemical composition of water in boreholes (sum of ions) was up to 1.2 times lower than that in well water. This was determined by higher sodium, sulphates, chlorine and nitrates amounts. When water level is decreasing, water chemical composition is increasing in water of wells and boreholes. It was determined that water in wells was contaminated with nitrate nitrogen, water in boreholes was polluted with ammonia nitrogen
