The creation of vulnerability maps for potential aquifer pollution is widely used in developed countries and is a basic tool for groundwater protection. This paper presents the assessment of the vulnerability from pollution of groundwater in the Štip aquifer, with the help of GOD method, where are used three parameters: Type of aquifer, lithology of the unsaturated zone and depth of groundwater. The data for the three parameters are obtained from the geological-hydrogeological profiles of 22 exploitation wells and exploration boreholes. Analyzing the three parameters a GOD index value was obtained in the range of < 0.4–0.5, which corresponds to the medium vulnerability class and a value > 0.5, which corresponds to the high vulnerability class. Key words: vulnerability; GOD method; groundwater; Štip aquifer; alluvial sediments |
