The study was conducted in Hantebet catchment area which has a total area of 24.5 kmwith the major objective of assessing suitability of groundwater quality for drinking purposes through water quality index (WQI) investigation of the different hand dug wells in the watershed. This was done by subjecting the 20 groundwater samples collected to comprehensive physico-chemical analysis using APHA standard methods of analysis. For calculating the WQI, 10 parameters have been considered: pH, sodium (Na+), potassium (K+), magnesium (Mg2+), calcium (Ca2+), chloride (Cl-), bicarbonate (HCO3-), sulphate (SO42--S), nitrate (NO3--N) and total dissolved solids (TDS). The WQI for these samples ranges from 54.41 to 86.24. All the groundwater samples estimated using the water quality index fall in the good water class and are all suitable for drinking purposes.
