Abstract

The levels of six trace metals namely iron, lead, manganese, copper, zinc and nickel were investigated in drinking water and groundwater sources in Ota, Nigeria. Detected concentrations of Mn, Cu and Zn were below the World Health organization and Standard Organization of Nigeria maximum permissible limits. Fe (92%) and Ni (53%) in some drinking water and groundwater sources were found in concentrations that exceeded the maximum permissible limits for these metals. Notably, the levels of Pb were below detection limit in all the bottled, well and borehole water, with exception of the hospital borehole, while the swimming pool had high concentrations of Fe (0.88 mg/L), Pb (0.21 mg/L) and Ni (0.19mg/L) compared to SON (0.30 mg/L), WHO (0.01 mg/L) and WHO (0.07 mg/L) respectively. Pollution indices indicated significant pollution of Pb, Fe and Ni. Overall, the mean metal levels in the sampled water sources followed a descending order, Fe>Cu>Zn>Ni>Pb>Mn. Some of the drinking water and groundwater sources could be considered safe for drinking, but proactive measures should be taken to check the levels of Fe, Pb and Ni in the swimming pool.
