Fatoye A. O., Gbadegesin KAJ

Abstract: The purpose of study was to assess heavy metals (Fe, Cd, Pb, Zn, Ni) in drinking water. Twenty samples were analysed using atomic absorption spectrophotometer. The result show that the average heavy metal levels in all water samples followed a descending order Zn>Fe> Pb > Ni> Cd. It was observed that heavy metals investigated exceeded the maximum permissible limit in drinking water as specified by regulatory bodies except cadmium which was below standard. Pollution index result confirmed significant pollution in Pb, Ni and Fe.
