The investigation of the weathered basement around Bauchi metropolis has been carried out. The objectives of this study were to determine the erodibility of the soil, evaluate its chemical characteristics and heavy metals content of groundwater, its hydrogeochemical controls and suitability for drinking. A total of thirteen soil samples from different locations were used for geotechnical analysis. The geotechnical result indicated mean plasticity index of 17.20%, mean optimum 9.30cm3, moisture content of 7.67% at mean maximum dry density of 2.50g/cm3. A mean cohesion values of 0.25cm2/kg and a mean angle of internal friction value of 30.80o suggesting very erodible of the soil. Nine groundwater samples were collected from the Bauchi. Field measurements of physical parameters were preceded by chemical analyses of the samples for major ions concentrations and bacteriological content. The groundwater has pH ranging from 6.90 to 7.10 implying that the groundwater sources are alkaline. The mean values for chloride, sulphate and iron are 158.89mg/l, 95.78mg/l and 8.70mg/l respectively. While the mean value for hardness is 381.29mg/l. These parameters indicate presence of mineral suphate, corrosion and very hard water therefore should be treated before use. Generally, erosion control structures in the area should be made of materials that should resist staining, corrosion and incrustation.
