Comparing the concentrations of heavy metals in water and sediments, it can be concluded that the heavy metals are highly accumulated in sediment samples than in water samples. This is because sediments act as reservoir for all contaminants and organic matter descending from the quarry site and ecosystem. The result is in line with the previous studies in Itu river (Elijah.,2001). Carrol (2008) stated that iron appears in the river sediments as an essential component of clay.
