ABSTRACT: This article evaluates hydrogeologic properties of the Paleogene and Quaternary sediments in the Šarišská vrchovina upland. The discharge and permeability of individual lithofacial members has been expressed using hydraulic parameters, obtained from both the odberove skusky from the hydrogeologic wells and indirectly by evaluating the average discharge, using hydrometric methods. The groundwater circuit takes place predominantly in the shallow subsurficial zone and only a small amount descends into greater depths and participates in formation of mineral waters.
