Comparative analysis of water quality stored in concrete and steel tanks In Ijebu Ode, Ogun State, Nigeria
Abstract
Storage facilities are commonly used to ensure that, there is adequate water for the societal need. This study examined the effect of water quality stored in concrete and steel tanks in different location of Ijebu-Ode Water Corporation, Ogun State, Nigeria. The effect of storage from different tanks was assessed by comparing the water stored in steel tanks to concrete tanks, and the result is compared with World Health Organization (WHO, 2017) drinking water guidelines. The result showed that the water was polluted with lead and Zinc at concentrations that could result in deleterious health effect in human. Result also showed that, iron (Fe) and nikel (Ni) were higher than the permissible guideline with the result given as (0.41, 0.38) in concrete tank and (0.23, 0.48). The bacteriological analysis obtained revealed that there was high concentration of bacteria found in all the water samples. Bacterial isolates such as Escherichia coli, Bacillus specie and Aeromonas specie, Salmonella specie were present in the water samples. Therefore, there is a need for further treatment of the water, before it is distributed to the end users.
