isotopes; the Zagreb aquifer

Sažetak
The Zagreb aquifer is the most important source of water supply of the town Zagreb, where from about 5, 5 m3/s of groundwater is pumped. Groundwater samples have been taken in various hydrological conditions at 15 piezometric wells at various depths.Main ions, stabile isotope of oxygen (δ 18O) and hydrogen (δ 2H), radioactive isotope of carbon (14C) and tritium (3H) were analysed in water samples. The Zagreb aquifer in the hydrochemic and isotopic sense is layered, especially in parts, which are far away from the Sava River. The shallow parts of the aquifer are under the present recharge and water in the deep parts of the aquifer has long residence time. Also, the deep parts of the aquifer in the Črnkovec and Petruševec area, which are situated at the opposite side of the Sava River, are unique hydrogeological system.
