This work present results of the hydrochemical and isotopic studies on groundwater samples from the study area. Chemical and environmental isotope data are presented and discussed in terms of the origin of dissolved species and of groundwater. All of the investigated groundwater are categorized into two chemical types: low and relatively high mineralized waters type. Interpretation of chemical data, based on both thermodynamic calculations and stability diagrams, suggests that the chemical evolution of groundwater is primarily controlled by water-rock interactions. Interpretation of ¹⁸O and ²H suggests that the recharge of the investigated groundwater may result from differents mechanisms
