This study assessed the levels of heavy metals in drinking water sources in Enyigba community in Abakaliki Local Government Area, Nigeria. Four sites were visited for sampling: two surface water (streams) and two underground water (boreholes). Three water samples were collected from each source making it a total of twelve water samples. The levels of Arsenic (As), Cadmium (Cd), Copper (Cu), Zinc (Zn) and Lead (Pb) were determined using an Atomic Absorption Spectrophotometer (AAS). The result showed significantly (P˂0 .05) high level of As, Cd and Pb which also exceeded the World Health Organization (WHO) recommended maximum limits specification for drinking water. The metal index revealed significant (P˂0.05) elevated level of As, Cd and Pb. There was no significant (P˃0.05) difference between the stream water and borehole waters in terms of their elemental load. The findings suggest that drinking water from these sources are heavily contaminated by As, Cd and Pb and there is possible risk of contamination of the diverse ecosystem located in the neighbourhood. Therefore, the mining communities and the miners should be properly enlightened on the dangers associated with exposure to heavy metals to prevent them from polluting water bodies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
