This research study involves the determination of the hydrochemistry of groundwater and it suitability for drinking, domestic usage and other purposes in the area. Result shows that pH value ranges from 6.40 to 6.54, indicating that the water is slightly acidic. Hardness range from values 2.68mg/l to 5.05mg/l, with an average value of 3.8mg/l, indicating that the water from the area is soft. Electrical conductivity (EC) level ranges from 6.02[endif]--> 13.59 µS/cm with a mean value of 9.84µS/cm. TDS range from 9.07mg/l to 17.01m with a mean value of 12.98mg/l. Calcium (Ca2+) and magnesium (Mg2+) range from 2.59mg/l to 4.08mg/l and 0.52mg/l to 1.23mg/l with average values of 2.82mg/l and 0.93mg/l respectively. Potassium (K+) ranges from 0.21mg/l to 1.61mg/l with a mean value of 0.93mg/l. Chloride (Cl-) range from 6.26mg/l to 12.70mg/l with an average of 10.2mg/l. Iron (Fe2+) range from 0.02mg/l  to 0.97mg/l with an average value of 0.45mg/l. Sodium (Na+) range from 0.37mg/l to 2.37mg/l. Bicarbonate (HCO3-) on the other hand range from 11.20mg/l to 20.48mg/l. The hydrogeochemical data collectively indicates that the ground water within this area is not highly mineralized. The values are within permissible limits when compared with WHO (2006) with exceptions of the pH and iron contents which revealed some high concentrations. Also the Cl- level indicates no salt water encroachment. The dominant cation and anion in the groundwater from the studied area are Ca2+ and HCO3- respectively.
