Abstract
This study was undertaken to determine the quality of surface, harvested and ground water of IGBANKE in Orihionmwan area of Edo State, southern Nigeria. Five water samples were collected from harvested water (well), four from surface water (river), and one from bore hole. The result of the analysis showed that appearance (clear), Calcium (0.185-0.445), Manganese (<0.05), Magnesium (0.106-0.124), Nitrate (0.004-0.011), Iron (0.008-0.109), Phosphate (0.000-0.006), Zinc (0.006-0.0015), Cu (<0.05), Cr (0<0.05) , Ammonium-N (0.003-0.008), Sulphate (0.006-0.026), Electric conduction (28-88) and pH (5.42-5.87). The results gotten were compared with the World Health Organization standard (W.H.O) 1995, to determine quality of the water. From the result, all the parameter falls within the permissible limit for drinking water set by World Health Organization (W.H.O.)
