Hydrogeochemical studies are carried out for the groundwater of Madaragally village using a computer technique. The analysed groundwater data is processed using the HYCH program. HYCH is capable of providing the required output using the major ion chemistry data for classifying and identify the suitability of the groundwater for agricultural purposes. The suitability of the groundwater for irrigation is based on water chemistry, facies, mechanism of origin, type, suitability and usage factors such as corrosivity and permeability. The present study revealed that the groundwater is fresh with high salinity and low sodium hazard, belongs to MgHCO3 facies and of both permanent and temporary hardness category. The chief mechanism controlling the chemistry of groundwater of this area is rock interaction. In overall, the quality of the groundwater is good and is suitable for agricultural purposes.
