dc.description.abstractThe study examined the effects of Kaduna refinery effluents on water quality of River Romi Kaduna State. The study was conducted within three (3) months and aimed at assessing the effect of KRPC effluent on water quality of the river before, after and at the point of discharge, effect on farming, swimming and fishing activities. A structured questionnaire was designed to source information from farmers and the physico-chemical parameters and heavy metals were analysed using Atomic Absorption Spectrophotometer. The before and after the point of discharge mean values for pH7.45 and 6.72, Temperature34oC and 34oC, 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 and4.37mg/l, COD 45mg/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, Cd0.022mg/l and 0.024mg/l, As 0.045mg/l andand Cr0.22mg/l and 0.21mg/l were estimated.The laboratory results were compared with the permissible limit allowed by NESREA and WHO and the result reveals that pH, Oil and greaseare within the standard at upstream and downstream but deviates at discharge point while Temperature, EC, TSS, TDS, Turbidity, COD, Pb, Cd and Cr at all the three sampling sites are above NESREA and WHO standard. DO, NO3, Fe, Cu, and Zn values are within the permissible limitsalso Colour is light brown at upstream, downstream and at discharge point.Statistical techniques were employed in the analysis of the data collected from the respondents to determine the effect of the effluents andthe results revealed thatRiver Romi has become contaminated by the effluents discharged. It was observed that the farmers have been experiencing reduction and loss of fish production. The solution proffered includes rehabilitation and cleaning of effluent water retention pond so that effluents water should be treated before discharge. KEPAand NESREA should ensure compliance with national standard for drinking water quality guidelines.en_US
