    The physico-chemical analysis of effluents from diverse factories in Agbara and the fresh water bodies receiving these effluents in Ogun State, Nigeria was carried out to establish the effect of the effluents. The study analyzed the effect of industrial effluent discharge on Ologe Lagoon. Sampling points; W3, W4, W5, W6, and W7 were effluents discharged directly from the factories located within Agbara industrial estate. Sampling points W1 to W7 were chosen along the water body before and after discharged of these effluents to reflect the contribution and the effect of the industrial and domestic effluents. The study revealed that BOD values were 13.04, 75.99, 13.04, 16.48, 14.92, 14.37 and 14.82 for sample W1, W2, W3, W4, W5, W6, and W7, respectively. Except for sample W7, all pH values were all in the basic region with conductivity ranging from 64 μs/cm to as high as 631 μs/cm. The total hardness value ranges from 1.83 to as high as 6.50 whereas the calcium hardness ranges from 0.25 to 1.63. The mean concentration of heavy metals ranges from 2.01ppm – 7.60 ppm, 0.45-1.42 ppm, and 3.0-8.0 ppm for Cu2+, Fe2+, Pb2+, Cr2+ and Zn2+ respectively. With the exception of zinc and iron, the discharge of copper exceeded the maximum permissible limit given by the Federal Environmental Protection Agency of Nigeria (FEPA) and WHO. Similarly, mean level of total suspended solids (TSS), values are 700 mg/L, 1700 mg/L, 2200 mg/L, 200 mg/L, 400 mg/L, 1600 mg/L and 900 mg/L for samples W1, W2, W3, W4, W5, W6, and W7, respectively while for total dissolved solids (TDS) the values are 50 mg/L, 70 mg/L, 40 mg/L, 830 mg/L 10 mg/L, 110 mg/L and 160 mg/L for samples W1, W2, W3, W4, W5, W6, and W7, respectively. There is need for pre-treatment to be carried out on industrial effluent before discharge into water bodies, without this, there is tendency of these pollutants to persist in the water and its uptake may cause long term health problems to living things.
