ABSTRACT
This study is aimed at evaluating the level of heavy metal of some borehole water of selected secondary school in Ikono Local Government, Akwa Ibom State, Nigeria. Borehole water sample from Ikono Local Government Area were collected and analyzed for Cr, Cd, Pb, Ar, and Cu. Using Atomic Absorption Spectrophotometer techniques. Result showed varying concentration base on location. High concentration of Cr, Cd and Pb were detected in all the borehole samples and are higher than WHO standard for drinking water. High level of the metal may also be associated with mobility of metals in soil, rate of infiltration and nature of the soil. Abnormal level of these heavy metal can result to health hazard to the consumers of the bore hole waters. Further treatment should be conducted before consumption.    Â
