The tests were analyzed for their mineral constituents counting Zn, Pb, Fe, Mn and Mg utilizing the Nuclear Assimilation Spectrometry (AAS) whereas Na, Ca, and K were analyzed utilizing Fire Emanation Spectrometry (FES). The ranges of metal concentrations gotten are; Zn (7.06 mg/dm3 – 13.44 mg/dm3), Pb (0.05 mg/dm3 – 0.135mg/dm3), Fe (0.052 mg/dm3 – 0.53 mg/dm3), Mn (0.102 mg/dm3 – 0.383 mg/dm3), Ca (28.50 mg/dm3 – 87.52 mg/dm3), Mg (7.34 mg/dm3 – 29.4 mg/dm3) , Na (13.95mg/dm3 – 22.98 mg/dm3) and K (40.08mg/dm3 – 78.2mg/dm3 ). From the levels of metals analyzed, it can be concluded that concentrations of Zn, Pb, Fe and Mn were all over WHO and Child allowable limits in all inspecting regions. This demonstrates an increment in metal contamination stack, likely due to fertilizer development, agrarian cinders and sewage-effluent run-off squanders. Water tests sourced from this stream may be that as it may be utilized for agrarian and water system purposes but unfit for human utilization.
