Abstract

Sixteen physico-chemical parameters of were investigated and used to estimate water pollution status. The River was sampled for seven months (February –August, 2019) and analysed following standard procedures and protocols. There were no significant differences (P > 0.05) among all the investigated physico-chemical parameters across stations. Mean values of all the investigated physico-chemical parameters were within the Federal ministry of environment FMEnv.) set standard except, dissolved oxygen and pH and chemical oxygen demand. Most of the investigated parameters were higher during rainy season with exception of water temperature, pH, dissolve oxygen (DO), biological oxygen demand (BOD) were higher during dry season months. The values of each phyisco-chemical parameters were used for estimation of water pollution index. All the water quality indices both for drinking and irrigation were also favourable and within their respective acceptable limits; except comprehensive pollution indices for drinking water
