This study was conducted to evaluate the effect of industrial effluents on Gurah-Loh-Mancha stream water, Jos, Nigeria. Water samples were collected from four sampling points along the length of the Gurah-Loh-Mancha stream that serves as the Industrial waste effluents dump sites. The Samples were analyzed for physicochemical parameters by classical methods and heavy metal concentrations were determined by Spectrophotometric method using Agilent MP-AES 4210 Spectrometer. The result of the study was analyzed using ANOVA. The study revealed that the industrial effluent discharge into the stream water has a high degree of physicochemical parameters; Color (393.0 ±4.24 mg/l) and Turbidity (20.33± 1.53 NTU) maximum values were found to be above WHO/FEPA health-based permissible standard of 15 TCU and 5 NTU, respectively. But in heavy metals, Cd (0.07±0.01 mg/l), Pb (0.135±0.148 mg/l) maximum values were > WHO limit 0.003 and 0.01 mg/l respectively and Mo (0.015±0.070 mg/l) maximum value > FEPA/WHO (0.01 mg/l). Gurah-Loh-Mancha stream water quality became deteriorated due to the high degree of pollutants discharged into it which makes it unfit for human use, hence the need for treatment before discharge.
