Abstract

Major ion chemistry such as Ca, Mg, Na, K, CO3, HCO3, Cl and SO4 along with physical parameters such as pH, EC, TDS and H were analysed to study and assess the water quality status of Doddhalla Sub-basin, Karnataka, India. Geologically, it forms part of Kaladgi Basin. Groundwater in the study area is neutral to moderately alkaline in nature. Piper’s diagram for hydrochemical facies classification of groundwaters shows water samples to be of class – mixed CaMgCl and NaCl type. EC varies from 620 to 3798 µS/cm. Water samples were compared with Indian and International standards to determine its quality for drinking purpose and almost all of the samples are within permissible and allowable limits. Classification based on SAR for irrigation suitability revealed all samples to be in excellent category. Wilcox diagram suggested 68% of water samples to be in good to permissible category.
