  Rezumat:   The chemical behaviours of groundwater are dynamic fields of research. Variations and changes of groundwater, as drinking water source composition impress negative effects on human health. In Romania, groundwater represents free and common fresh water. Chemistry and quality of groundwater is changed due to natural and anthropogenic factors. The aim of this study is to determine and evaluate the chemical composition of groundwater from the northern part of Sibiu County using Piper, Durov, and ion balance diagrams. The graphical representations show the type of waters based on the ion content. As results, high concentrations of major anions (SO42-, Cl-, NO2-, NO3-) and cations (Ca2+, Mg2+ , Na+ , K+ ) were found and according to Piper and ion balance diagrams, the prominent types of waters are Ca2+ -HCO3- type.

Keywords: groundwater, chemical composition, Durov diagram, Piper diagram, ion balanced diagram
