Assessment of Heavy Metals in Borehole Water in Umuagwo- Ohaji L.G.A, Imo Sate

Water is one of the essentials that support all forms of life and heavy metals are among the water contaminants which find their way into water samples as a result of inadequate treatment, disposal of waste and industrial discharge. This work looked at the heavy metal contents (mg/l) manganese (Mn), lead (Pb) and cadmium (Cd) of borehole water samples in Umuagwo Ohaji, Imo State, Nigeria. Twenty different borehole water samples were assayed for Mn, Pb and Cd levels (mg/l). The result showed that Mn and Pb contents were within the limit allowed by WHO. But the Cd (from 0.003 – 0.02mg/l) levels were high compared to the WHO limit of 0.003mg/l. Therefore, treatment, and reduction of waste discharge around the borehole is advocated for, before it becomes too late
