Physio-Chemical Analysis of Industrial Effluents in parts of Edo States Nigeria

Water pollution, particularly, surface water results from all activities of man involving indiscriminate waste disposal from industry such as effluents into waterways, waste, agricultural waste, and all forms of man’s activities that results in contamination of the surface water. Wastewater samples were collected from two (2) carefully selected industries and the Physico-Chemical parameters were analyzed and compared to FEPA (Federal Environmental Protection Agency) standard. DO of the analysis ranged from 6.5 – 9.7mg/l, BOD value range from 3.2 – 8.8mg/l, there was no significant difference among study stations (P>0.05), TDS showed a high significant difference (P<0.001). The results obtained from the analysis indicated that the effluents from the industries were relatively treated as the contaminants sampled were within statutory limits. It was however observed that the effluent from this brewery was relatively treated.
