Twenty one representative groundwater samples were collected from Sari, Liari, Lang and other drainage basins. The samples were analyzed to elaborate geochemical characteristics, ionic composition and hydrofacies. Drinking and irrigation water quality were also assessed. Small seasonal aquifers were present within sub recent valley fills, above the folded rocks of tertiary period. However, permanent aquifers were located within the sandstone of Nari Formation of Oligocene age. The major ionic composition showed a wide variation in the hydrochemical properties of the groundwater of the area. The degree of correspondence among cations and anions has been estimated in order to evaluate their mutual relationships. Abundance of major elements was interpreted in relations to the composition of aquifer, bedrock and climatic conditions, which may contribute to the genetic affiliation. The important hydrogeophysical parameters have been estimated for reasonable assessment of groundwater quality for domestic and irrigation purposes. Ionic relationship is exhibited in the form of Stiff diagrams. Piper diagram has been used to classify the hydrofacies. Relationships between various elements have been identified from correlation coefficient, reflect genetic associations. Strong positive correlation exists between Na-K, Na-Cl, Na-SO4 and K-SO4.
