Analiza ryzyka dla obszaru spływu wód podziemnych do ujęcia Łazy Błędowskie GPW S.A. w Katowicach i jej ograniczenia

Abstract

The paper presents the procedure of risk assessment for the catchment zone of the Łazy Błędowskie groundwater intake, performed in accordance with the Water Law Act. Identification and analysis of contamination sources resulting from the land use patterns, as well as water qualitative research and health risk assessment with a view to factors negatively affecting the water quality, were carried out based on the hydrogeological report and analyses. The limitation on risk assessment, constrained by specific local hydrogeological, hydrogeochemical and environmental conditions, was indicated, including the need to establish the sanitary protection zone for the 8bis well. The planned cessation of the activities of Zn-Pb ores mining in the Olkusz area and associated changes in hydrogeochemical and hydrodynamic conditions within the area of the Łazy Błędowskie groundwater intake were taken into account as well.
