Assessment of Heavy Metal Concentrations in Borehole-Hole Water in Ozoro Town, Delta State

The level of heavy metal contamination in borehole water in Ozoro town, were determined using AAS. Ten borehole were randomly collected from different sampling sites. The heavy metal analyzed includes PB, Cu, Fe Zn, Ni Cr, and Co. The result showed that the concentration of lead, (Pb), Copper (Cu), Fe (Fe), Zinc (Zn), Nickel (Ni), Chromium (Cr) and Cobalt (Co) were within WHO maximum permissible concentration with mean values of 0.01mg/L, 0.028mg/L, 0.06mg/L, 0.05mg/L, 0.046mg/L and 0.001mg/l. The level of the metal followed the order Pb>Cu>Fe>Zn>Ni>Cr>Co. The heavy metals are within the maximum contaminant level set by WHO, 2015.
