Abstract: The water quality of GudBahri River, an important domestic and potable water source of Wukro, has been assessed. Water samples were collected from the river along different points and analyzed for various physio-chemical quality parameters during winter. Effects of industrial wastes, municipality sewage and agricultural runoff on the river water were investigated. The study was conducted between the Kaziha and Shigar-arho including Adi-akawn. The study involved determination of physical and chemical parameters of surface water at twelve different points. The mean values of Water Temperature, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Total Solids (TS), Turbidity, Dissolved Oxygen (DO), Bio-chemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH, Electric Conductivity (EC), Salinity and Chloride content were 26.030C, 1233.33 mg/L, 470.17 mg/L, 1703.50 mg/L, 9.60 NTU, 7.89 mg/L, 3.88 mg/L, 7.27 mg/L, 7.90, 672.83µs/cm,0.33PPT, 77.5 mg/L, respectively.
