Hydrochemical investigations of the surface water and the seasonal effect on the chemical budget of ions from the Olt river were carried out. Geochemical results show that the seasonal effect does not change the order of ion abundance. The Piper diagram was used for the classification of cations and anions, in terms of confidence in the major percentages of ions and types of water. According to the Piper diagram, the dominant hydrochemical facies in the study area is Ca–Na–HCO3−–Cl−, which represents 87% of the samples. The study area is influenced by natural processes of water–rock interaction such as dissolution of evaporitic rocks (gypsum, anhydrite, and halite).
