Rapid assessment of reservior water quality and suitability indices for drinking purpose: A case study of ero and ele reserviors in Ekiti state Nigeria (original) (raw)

International Journal of Multidisciplinary Research and Development, 2015

Abstract

Water is essential for sustenance of life and determines the overall socioeconomic development of any nation. However, with rapid increase in the population of the country, the pollution of water courses from human activities and the demand for potable water to satisfy the growing demography cannot be over emphasized. In this perspective, an attempt has been made to assess the drinking water quality in Ele and Ero reservoirs. The two reservoirs were constructed for drinking purposes. The results obtained from chemical and microbiological analyses were compared with two water quality standards namely National Standards for Drinking Water Quality (NSDWQ) and WHO. The parameters analyzed were the physio-chemical and microbiological parameters. These include; Temperature, Electrical conductivity, Total dissolved solid, pH, Total hardness, turbidity, chloride, iron, nitrate, fluoride and magnesium. The entire physio-chemical parameters were found to be within the permissible limits of NSDWQ and WHO, while microbiological quality parameters such as total coliform and feacal coliform were found to be beyond the limits. The high values observed with microbiological parameters in these water bodies suggest that they are not suitable for drinking purpose, unless some possible remedial methods are to be adopted to treat these water bodies.
