Physicochemical and Heavy Metal Indices of Oba River, Ogbomoso, South-West Nigeria.

This research aimed at assessing physico-chemical characteristics and occurrence of heavy metals in water samples from Oba River. The physico-chemical characteristics and concentrations of heavy metals were determined using standard methods. Data were analyzed using SPSS version 25.0. Practically, all the physico-chemical characteristics assessed fell within acceptable standards by World Health Organization and Nigeria Standard for Drinking Water Quality (NSDWQ). Cobalt, chromium, cadmium and lead were undetected from the water samples. Nickel and copper were only detected during the rainy season, while iron was extremely high during the rainy season. The anthropogenic activities around Oba River had insignificant effect on the water quality considering the water physico-chemical characteristics and heavy metals analysis. However, high iron concentration in Oba River during rainy season should be further researched to identify the source(s) and continuous management of the water body is required.
