Sixty groundwater samples were collected in different seasons from the study area. The water soluble products of congruent weathering reactions such as Na, K, Ca, Mg, HCO3, and SiO2 have been probed. Apart from these, anthropogenic parameters such as Cl, NO3, PO4, and SO4 have also been analyzed. The mathematical and graphical tools are used to assess the groundwater quality for drinking and irrigation purpose. The study reveals that the concentration of major ions is controlled by the water-rock interactions. The water is not at all suitable for drinking purpose. As per pH, TDS, SAR, chloride and sulphate concentration water is suitable for irrigation purpose. Critical verification of hardness, EC, RSC, salinity hazard compels to assign water quality doubtful for irrigation purpose. Such doubtful zones need special care and suggested to adopt alternative salt tolerance cropping pattern. Also it is advised to avoid excessive use of artificial fertilizer and excessive irrigation.
