Abstract: Groundwater from shallow wells were evaluated for irrigation purpose, within Ukwuoku Hills, Oju local government area of Benue State, Nigeria. The study area lies within Asu River Group of the Lower Benue Trough, southern Nigeria. Physicochemical parameters analyzed include physical parameters such as; pH, total dissolved solid and electrical conductivity and chemical parameters such as; major cation and anion. The above-mentioned parameters were analyzed using America Public Health Association standard method. Results from the study showed that pH falls within slightly basic to acidic, electrical conductivity ranges from 127 to 760μS/cm, Soluble Sodium Percentage ranges from 1.53 to 43.78, Sodium Percentage ranges from 1.55 to 77.8 % Kelly Ratio ranges from 0.01 to 0.77, Magnesium Absorption Ratio ranges from 0.00 to 61.98 and total hardness Total Hardness ranges from 72.00 to 425.5 within the study area. The above listed parameters were below various permissible standard value for irrigation except for MAR at OJU/LBT/04, Na% at OJU/LBT/09, 13 and 14, SAR at 01 and 04 and TH at OJU/LBT/04 that were slightly above various permissible standard values. From Gibbs plot it was observed that rock dominance is the major factor that influences groundwater except for few sampling points were precipitation dominance was observed to have influence on groundwater within the study area.
