The groundwater of the Middle aquifer was collected to examine its characteristics. The chemistry of the water showed that it has SAR value of about 4.6 and EC is 667 Scm -1 . This makes the water suitable as fresh water and can be used for irrigation. The results were presented in Richards and Piper’s diagrams for easy visualization. The water samples plots in good and permissible water class with salinity hazards of medium – high salinity groups. While the water samples plots in the same region in the piper’s diagram indicating that they are hydrogeologically connected and continuous. The chemical data recognized a water type classified as sodium bicarbonate type (Na + HCO3) facies where sodium is significant in its concentration; with cation and ions in the order of Na > Ca > K > Mg and HCO3 > CO3 > Cl > SO4 for drinking water quality.
