Abstract
The hydrochemical properties of the ground waters in the cave of Slatinski Izvor were analyzed monthly, from December 2011 to October 2013, in the dry period of the year (5 anions and 11 cations). Water was sampled at three points: the first one at 30 m from the cave’s entrance, the second one at 800 m from the cave’s entrance, and the third one in the cave lake at 1000 m distance from the cave’s entrance. Four methods (Piper diagram, Stiff diagram, Chadha diagram, and D’Amore diagram) were applied in order to determine the hydrochemical properties of the wa-ter samples. The results showed that all water samples have the same origin, all water samples belong to CaHCO3 water type, water has temporary hardness, and the aquifer is composed of dolomite and limestone.
Highlights
Karst areas are found in about 15% of the Earth’s surface [1], and karst aquifers hold significant amount of groundwater resources which is an important source of the drinking water
Because of the specific nature and unique hydrogeological characteristics, karst aquifers require adapted hydrochemical methods because they are different from other hydrogeological environments
The carbonate rocks are covered with Pliocene sediments which are well permeable with intergranular porosity
