The need to undertake an evaluative effect of industrial wastewater discharge on surface water with a case study of Nigerian Breweries Plc Enugu into the Ajali River was borne out of the need to ascertain the level of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solids (TSS) etc and other characterized effluent been discharged into the water body that determines the level of use and quality of this water for irrigation purposes, human consumption and safe ecological habitation of aquatic lives. To achieve this, laboratory analysis was carried out on the Ajali River and the wastewater discharged from the industry and it was confirmed not to have exceeded the benchmark for required discharge of wastewater into streams and rivers as stipulated by some regulatory bodies. In conclusion, treatment measures and regulatory policies were suggested to checkmate the abuse of this water bodies and the danger it might likely pose to aquatic ecological system if regulatory standards were not complied with.
