Hydrogeochspanical And Isotopic Investigation Of Nasrettin Hoca Springs, Eskisehir, Turkey

The aims of this study are to investigate the water quality, the contamination and water-rock interaction of the Nasrettin Hoca springs, with an ultimate aim of establishing protection measures. Within the scope of this study, the springs in and around the catchment area, Bağbaşı springs, Hatip spring, Ali spring, Saracık Fountain and Babadat spring, were investigated. The springs are of Ca-Mg-HCO3 type when basic hydrogeochemical features are considered, are under the influence of marble-limestone and metaophiolitic units located in the recharge area and are of shallow circulation. The trace element contents of the springs show the influence of the carbonate rocks comprising the reservoir (Sr) and the basement rocks (Ni, Al). The protection areas of Nasrettin Hoca springs against contamination are determined as three different zones by considering the hydrogeologic and topographical features of the region and the Turkish Standards.
