Abstract

The activity concentration of uranium in bottled and well water samples in Kuye area, Ogbomoso, Nigeria were measured using gamma ray spectroscopy method. The mass concentration values of both the bottled water samples and the well water samples exceeded the recommended safe limit of uranium in drinking water of 30 μg.l-1 by WHO. All the water samples investigated had their excess cancer mortality risk lower than the permissible limit of 10-3.The excess cancer morbidity risk associated with the intake of uranium in the drinking water samples investigated shows that only 80% of the bottled water sample and 22% of the well water samples were safe for drinking. All the water samples investigated were found to be unsafe for consumption in terms of their chemical risk as they all exceeded the hazard quotient of unity ranging from 12.55 to 34.14. The risk associated with drinking bottled water and well water in Iluju, Ogbomoso is due to cancer morbidity risk and chemical toxicity risk. Therefore, the study suggest that the consumption of bottled water and well water by the local people of Kuye may pose serious threat to their health.
