Investigation on Trace Metals Content of Some Selected Borehole Waters Around Umuahia Metropolis

Water samples collected from producing boreholes in and around Umuahia metropolis were analyzed to establish the presence of trace metals, their concentrations and compare them with World Health Organization (WHO) guidelines on drinking water. Analytical results obtained using A.A.S Unicam Solar 32 showed that only Fe and Mn were detected and were within (WHO) highest desirable limit. The total content of Mn and Fe were found to range from BDL to 0.434 ppm and 0.0999 to 0.295 ppm, respectively. In the various samples investigated Zn, Ni, Cr, Cd, Pd and Hg were found below detectable limit. The pH of all the samples were near neutral.
