Assessment of Physico-Chemical Parameters of Water from Iwofe River, Rivers State, Nigeria

This study is aimed at assessing the physico-chemical parameters of water from Iwofe River which heavily stressed by extensive anthropogenic activities like bunkering. Two stations were established and surface samples collected bi-monthly each station for one year. All determined in-situ except biochemical oxygen demand (BOD) was analyzed in laboratory on fifth day sample collection. The results obtained show that pH varied 5.66 6.87, dissolved (DO) ranged between 3.51 5.16 mg/l. Temperature had values ranging 27.85 31.25 oC; salinity 5.96 11.54 ppt; conductivity 9.55 10.46 us/cm. total solid (TDS) 7.15 13.63 mg/l 0.85 2.84 Seasonal fluctuations revealed mean DO, TDS, temperature higher during dry season while BOD wet season, but uniform both seasons. has shown despite visible perturbations area, still relatively clean.
