Description The potential impact of discharge of untreated abattoir effluent on water quality of the Ikpoba River has been investigated. Four sampling points were established along Ikpoba River downstream from the point of discharge; the first point, S1 was the point of discharge of the effluent into the river, the second point, S2 was 10m from S1; the third point, S3 was 50m from S1 and the fourth point, S4 is 100m from S1. The physicochemical properties of samples analysed were done in duplicate and mean values were obtained. The physicochemical parameters investigated were pH, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), temperature, chloride, biochemical oxygen demand (BOD), dissolved oxygen (DO), chemical oxygen demand (COD), turbidity and alkalinity. The range of values of the parameters were:5.65-5.91for pH; 61-667 µs/cm for EC; 30-334mg/L for TDS; 10-130 mg/L for TSS; 28.6-29.0 OC for temperature; 10.65-106.50 mg/L for chloride; 4.8-120 mg/L for BOD; 0.2-5.4 mg/L for DO; 64–660 mg/L for COD; 5.2-101.60 NTU for turbidity and15.25-152.50 mg/L for alkalinity. The values of all physicochemical parameters measured, with the exception of DO, decreased downstream. The values of alkalinity, chloride, temperature, EC and TDS at all sampling points were within the acceptable limits set by national environmental standards and regulations enforcement agency (NESREA) and world health organisation (WHO). The values of the other parameters were either within the maximum permissible limits set by the regulatory bodies at S4 or at S3 and S4 only. In general, the water is unsafe for drinking and poses a threat to aquatic life at S1 in terms of pH, TSS, BOD, DO, COD and turbidity with respective values of 5.91, 130 mg/L, 120 mg/L, 0.2 mg/L, 660 mg/L and101.6 NTU.
