Downstream Effects of Industrial Effluents Discharge on Some Physicochemical Parameters and Water Quality Index of River Rido, Kaduna State, Nigeria

The effects of industrial effluent discharge on the water quality River Rido in Kaduna South, State, were examined. These include Northern Noodles point, Refinery and points downstream Rido. An interval 100m between sampling was established to achieve an even representation points. physico-chemical parameters investigated pH, free dissolved carbon dioxide, alkalinity, hardness, sodium, electrical conductivity, Turbidity, total suspended solids, phosphate, nitrate, sulfate, oxygen. Mean levels turbidity Total solids phosphate at points, as well most areas study area, generally above permissible limits for drinking water. Statistical differences observed concentration control point area. However, be similar indication contamination by upstream. Notwithstanding, index both shows that river ranged from good excellent Rido, respectively. This might attributed effect dilution rainfall. It is therefore recommended wastewater refinery northern noodles properly treated before discharged into
