Abstract: This study aims at using the water quality index (WQI) in the assessment of groundwater for agriculture and irrigation purposes. This was possible with the aid of several water quality indices including Sodium Adsorption Ratio (SAR), Magnesium Adsorption Ratio (MAR), Sodium Percentage (Na %), Permeability Index (PI), Residual Sodium Carbonate (RSC), Kelly’s Ratio (KR) and Potential Salinity (PS). All the quality indicators show that the groundwater sources in the area are excellent for irrigation purposes. In this study, electrical conductivity (EC) ranges from 3.20 to 139.32 mg/L with mean and SD values of 47.32±45.20 mg/L. Based on Richard’s classification scheme, the groundwater sources are of low salinity hazard (
