Sažetak
Hydrogeological investigations using hydrochemical and isotopic methods have been performed to determine the sanitary protection areas of springs in the drainage area of the Vransko Polje near Biograd (North Dalmatia) and main springs in the drainage area of the Gacka River (Lika region). The two investigated areas are situated in the Dinaric Karst that comprises very important groundwater storage reservoirs in Croatia. The chemical composition of spring waters from the Gacka River recharge area shows low concentration of total dissolved salts. Low concentrations of nitrates, amonium and phosphates indicate non-polluted ground waters in this area. Hydrochemical composition of spring waters in the Vransko Polje recharge area shows seasonal vegetation and hydrological variations (Cl-, SO42-, NO3-) closely related with the sea water influence and anthropogenic activities. The sewage waters from settlements and agriculture activity affect the quality of spring waters mainly after a dry season when the precipitation washes out soil and the unsaturated zone of karst aquifers. The mean 3H activity in all main springs in the Gacka River area is similar to that of precipitation, while in the springs of Vransko Polje the mean 3H activity is lower if compared with precipitation due to sea water infiltration. There is no seasonal fluctuation of 3H activity in all springs indicating fast circulation and good mixing of precipitation and ground waters. Correlation between d2H and d18O in both areas showed the values close to the MWL but with distinguish differences with lower values for Gacka river springs (higher altitude, continental climate) and higher for Vransko Polje springs (Mediterranean climate, low altitude). Also the stable isotope data show only weak seasonal variations, again indicating a fairly short mean residence time and good ground water homogenization. Stable as well as radioactive isotope data indicate that both areas are very sensitive to any kind of pollution and the response to the pollution will be very fast. The results of this project will be used in definition of protection measures for the water supply for the recharge areas of Gacka River and Vransko polje springs and establishment of close cooperation between hydrogeolgists from Hrvatske vode, Environmental Geochemical Laboratory and institutions that perform the isotope analyses such as Rudjer Bošković Institute, Zagreb and Stable Isotope Laboratory, Rijeka.
