This study showed the potential discharge of various hazardous heavy metals in the water body through seepage in Owode-Onirin, Ikorodu area of Lagos Sate and Lafenwa scrap yard, Abeokuta, Ogun State due to uncontrolled activities of scrap yards. The results showed that the physicochemical parameters and of heavy metals concentration in surface water from most of sampling locations exceeded permissible limits set by Standard Organization of Nigeria drinking water specifications standard (SON 2007) and WHO (2004) for drinking water. Variations in concentrations of these various heavy metals in water sampled are a consequence of a wide range of scrap yard activities within the neighbourhood.
