Sampling surveys were undertaken July 2004 from wells. Eighteen variables (temperature [T, °C], pH, total dissolved solids [TDS], Na+, Cl−, Ca2+, Mg2+, SO42−, K+, HCO3−, Fe3+, Mn2+, Zn2+, Al3+, Pb2+, Cr3+, Cu2+, F−) determined samples. We applied conventional classification techniques, such as Piper diagram scatter plots, evaluate geochemical processes. In addition, two multi-variate statistical methods, hierarchical cluster analysis (HCA) components (PCA), sub-group data set their usefulness classify Results show that area generally brackish highly very saline. The abundance major ions follows: Na+ > Ca2+ Mg2+ K+ = Cl− SO42− HCO3−. Concentrations trace elements low, under maximum recommended level human use. PCA indentified three factors explaining 74 percent variance quality; variations related degree mineralization. HCA shows wells broadly divided into groups based on similar characteristics. Finally, results indicate properties varied spatially, evolution study controlled prevailing processes dissolution precipitation salts minerals, ion exchange, recharge origin.
