Heavy metal concentration of the water in the sewage treatment pond of the Ahmadu Bello University Zaria, Nigeria, was studied between April and September, 2007 using Energy Dispensive X-Ray Fluorescence (ED-XRF)analysis. The Mean ~c S.E of ten (10) Heavy Metals observed during the study is as follows: Vanadium 0.75 ~c 0.07mg/L; Chromium 0.69 ~c 0.04mg/L; Manganese 0.61 ~c 0.06mg/L; Iron 0.40 ~c 0.03mg/L; Cobalt 0.31 ~c 0.02mg/L; Nickel 0.25 ~c 0.02mg/L; Copper 0.25 ~c 0.02mg/L; Zinc 0.31 ~c 0.08mg/L; Arsenic 0.24 ~c 0.02mg/L and Lead 0.31 ~c 0.08/L. Metal Index of between 67.32-93.72 was observed during the study period. Metals like Lead, Arsenic, Nickel, Iron, Manganese and Chromium showed concentrations above NIS and WHO Maximum Allowable Concentration for drinking water while metals like Zinc and Copper showed concentrations below the NIS and WHO Maximum Allowable Concentration for drinking water, Vanadium and Cobalt had no values for comparison.
