Physical, chemical and microbiological analyses were used to determine the wholesomeness status of seven stream waters used for drinking in Owo. The study revealed that the water were wholesome from chemical analysis point of view while three out of the streams met the WHO recommendation for taste, odour, appearance turbidity and total dissolved solids. Microbiological analysis showed that all the samples had viable count of bacteria above 100cfu/ml, all positive for coliform,
The potential of water to harbour microbial pathogens and causing subsequent illness is well documented for both developed and developing countries (Wright
Federal Ministry of Health gave a statistics in 1994 that only about 30% of Nigerian have access to potable water (Dada & Ntukekpo, 1997) while in the same year, United Nations estimated that 1.2billion people lacked access to potable water world wide(Oyeku
Materials And Methods
Results And Discussion
The results of the physical analysis of the water from the seven streams were shown in table1. Analysis for the taste showed that water samples from White house, Ijasan and Ogbara streams had a good taste. This is different from the report of Edema
Result of microbiological analysis showed the presence of coliforms, pathogenic and non coliforms, heterotrophic bacteria including opportunistic pathogens such as
Conclusion And Recommendation
With the physio-chemical qualities of the streams they are only suitable for agricultural uses while microbiologically the streams are unsafe and unsuitable for domestic use. Consumption of the water will expose the consumer to waterborne disease. There is urgent need for awareness to be created about the present situation of these streams to alert consumers on the need for further treatment of these water before they can be used for drinking and other domestic uses.
