This study examines the effect of industrial effluents on the water quality of the Aba River. In order to achieve this, a total of six water samples were collected each season and was analysed for different wastewater characteristics of temperature, water pH, Conductivity, Alkaline, Chloride, BOD5, COD, DO, TS, THC, TDS, Zn, Cd, Fe, Pb, Cr, Total Coli-form and E-Coli. Using APHA Standard Analytical Method, the results shows that during dry season, temperature, pH, Chloride and Zn values were found to be lower than NESREA Standard. While TS, THC and Total Coli-form values were found to be higher than NESREA standard in dry season
