EFFECT OF EFFLUENT DISCHARGES OF KADUNA REFINERY ON THE QUALITY OF ROMI RIVER, KADUNA STATE
Keywords:Effluents, River Romi, Water quality, Discharge, Upstream, Downstream
This study was carried out in November 2017 and examined the effects of Kaduna refinery effluents on water quality of River Romi in Kaduna state. The study was conducted within three (3) months and aimed at assessing the effects of Kaduna Refinery effluents on water quality of River Romi before, after and at the point of discharge on the farming, swimming and fishing activities within the study area. Before and after the point of discharge mean values were analyzed at pH7.45 and 6.72, Temperature at 34°C and 34°C, TSS 68mg/l and 96.0mg/l, TDS 300mg/l and 324mg/l, Turbidity 12NTU and 16 NTU, Colour is light brown, Oil and grease 2.7mg/l and 4.7mg/l, BOD 3.45mg/l and 4.37mg/l, COD45mg/l and 66mg/l DO 6.7mg/l and 6.4mg/l, NO30.2mg/l and 0.7mg/l, Cu0.2mg/l and 0.36mg/l, Fe0.93mg/l and 0.2mg/l , Zn 0.27mg/l and 0.36mg/l, Pb0.221mg/l and 0.228mg/l, Cd0.22mg/l and 0.024mg/l, As 0.045mg/l and Cr0.22mg/l and 0.21mg/l were estimated respectively. The laboratory results were compared with the permissible limit allowed by NESREA and WHO standards and the results revealed that pH was within the standard at upstream and downstream but deviates at discharge point while Temperature, EC, TSS, TDS, Turbidity, COD, Pb, Cd and Cr ....
