Assessment of physicochemical properties of stream sediments of River Ayimoro within the quadrant 08019`24``N, 08021`06``N to 004 02`40``E 004004`46``E, Northwest of Ogbomoso was carried out to provide baseline information for mineral exploration purpose. Composited sediment samples were collected for each location and analyzed for physicochemical parameters (i.e. pH, Organic Carbon (OC) and Organic Matter (OM); Electrical Conductivity (EC) and Particle Size Distribution (PSD) in EMS laboratory using standard methods and also for elemental composition at the Activation laboratory using the method of Inductive Couple Plasma-Mass Spectrometry (ICP-MS).The results obtained indicated a pH of 9.4 and 8.8 for sediments of the two locations(Tewure Iju and Elesun Aiyetoro respectively) thereby indicating that the sediments of these areas are basic. The sediments of Tewure Iju and Elesun Aiyetoro have an EC of 180us/cm and 240us/cm. The low EC indicates that the sediments are also found within the geological materials. The OC and OM of the study areas are also low indicating that the geologic materials have low tendency of capturing carbon which foster the formation of organic matter. The particle size distribution of sediments of the study areas showed that the areas is not well drained. High percentage of sand (92.8% and 60.40% for both Tewure Iju and Elesun Aiyetoro respectively) indicates that sand is the main geological material found in the setting.Manganese (Mg) and Barium (Ba) are the most concentrated metals present in the sediments of both location. The high composition of Mn and Ba indicates that they tend to settle within shorter period of deposition. Using the standard deviation (SD) and the highest mean values, Mn is the most distributed metal across the study area while Mo is the least distributed. Other elements (Pb, Co, Cu, Fe, Cr, Al, and Mo) analyzed for are found to have low concentration in the sediments of the study areas using their corresponding calculated background values. Trace elements like Li, Be, Sc, V, Sr, Y, Zr, Tl, and U were also analyzed for with Vanadium (V) having the highest composition both in the soils and sediment of the study areas. Using the SD also, V is the most distributed metal while Tl is the least distributed in the study areas. These presence of these heavy metals have made the streams inconsumable and has also affected the livelihood of these habitants.
