Because a connection between the Poçemi springs and Vjosa River in South Albania was suspected, the determination of the origin of springs was of a particular interest for the high dam proposed to be constructed on Vjosa River valley, about 2.0 km south to these springs. Environmental hydrochemical and isotope tracers are successfully applied to establish the possible connection between Poçemi springs and Vjosa River. A program of independent hydrochemical was conducted for a period of nearly two years. Sulfate ion (SO 4) was used as a specific tracer, but conductivity is also indicative. This was facilitated by the relatively high SO 4-concentration in Vjosa River than the SO 4 concentration of the karst groundwater recharging the local spring. It resulted that about of 80 % of the water discharged by the Poçemi springs is recharged from Vjosa River and about 20 % is locally recharged. The results of hydrochemical investigations are in very good harmony with the results obtained from the environmental isotope methods.
