  Rezumat:  The main springs of the Gacka River drainage area (Majerovo vrelo, Tonković vrelo and Pećina) have been studied by means of stable (18O) and radioactive (3H) isotope measurement. This area is situated in the Dinaric karst that comprises very important groundwater storage reservoirs. Since karst is characterized by high permeability, porosity and crevices in which water moves in complex subterranean networks, it is very sensitive to any kind of pollution. Gacka River is located in the Lika region at an altitude of about 400 m above sea level. Although its climatic conditions are mainly continental, the situation is complicated by the occasional influence of maritime Adriatic air masses. Water samples from the three springs (continuous sampling, some other springs occasionally) as well as precipitation were collected monthly in the period 2005-2006. Tritium measurements have been performed at the Laboratory for Measurements of Low-level Radioactivity of the Rudjer Bošković Institute, Zagreb, while stable isotope δ18O measurements were carried out at the new stable isotope facility (Environmental Physics Laboratory) at Rijeka University.
