Metals are elements, present in chemical compounds as positive ions, or in the form of cations (+ ions) in solution. Metallic elements which have high atomic weight and density much greater (at least 5 times) than water are known as heavy metals. The aim of the study was to analyze some selected heavy metal pollutants, Copper (Cu), Iron (Fe), Zinc (Zn), Lead (Pb), Chromium (Cr) and Cobalt (Co) in the water of Chamo Lake. In the analysis work, the water samples were collected from four different sides of Chamo Lake randomly and analyzed their content of level concentrations of Cu, Cr, Co, Fe, Zn and Pb by using Atomic Absorption spectrometry. The pH and EC of the water sample was obtained by using pH-meter and electrical conductivity. The analysis showed that the Concentrations level of Copper (1.068 mg/L) and Lead (0.114 mg/L) were higher than their standard concentration 0.05 mg/L and 0.01 mg/L respectively and the concentration of Zinc (2.34 mg/L), Iron (2.26 mg/L) and Chromium (0.023 mg/L) and Cobalt were lower than their standard concentration level 5.0 mg/L, 5-43mg/L, 0,05mg/L respectively. Therefore the Lake Chamo is slightly contaminated by the heavy metal pollutants Lead and Copper, when compare to Iron, Zinc and Chromium.
