ABSTRACT: In 2012, the State Geological Institute of Dionýz Štúr started to solve the geological task of "Monitoring of Environmental Burdens in Selected Sites of Slovakia", whose main objective was to build and implement a monitoring network on 161 sites of environmental burdens. In the paper, attention is paid to the environmental impact of Banská Belá – Sedem žien tailings on the environment on the basis of the results of the above mentioned task and the ongoing monitoring. There was not observed significant anthropogenic impact to groundwater quality of the monitoring wells. The negative influence of the tailings was found in the drainage waters of the tailings. Values exceeding the limits for the general quality of surface water according to Government Decree 269/2010 were found for conductivity, sulphate, Ca2+, NH4+, Mn, Cd and Zn. Elevated contents of several indicators (sulphates, Ca2+, Mn, Cd, Zn) were also found in the Beliansky stream "below the tailings". Exceeding the indicative (ID) or intervention (IT) criteria according to Regulation of the Ministry of the Environment of the Slovak Republic no. 1/2015-7 was found in sediments of tailings drainage water for several chemical parameters (As, Pb, Hg, Cd, Zn).
