Management of the ever-increasing generated solid waste had been a difficulty for state governments inNigeria. The high costs connected to this waste management which had encumbered the state budget,ignorance or lack of understanding of resourceful waste management and insensitivity to environmentalconcerns may have led to partial neglect of this sector. This research paper is aimed at evaluating therehabilitation potential and the risk level of Igbatoro dumpsite, an Ondo state-managed waste dumpsitewhich predominantly receives the waste of Akure and its environs. In determining rehabilitation/recon-struction potentials and assessing the risk of the dumpsite, an Integrated Risk Based Approach (IRBA) wasconsidered. The Risk Index (RI) was calculated from the addition of the sensitivity index output with theattribute weightage of the twenty-seven (27) parameters studied. A total risk index of 571.58 wasobtained for Igbatoro dumpsite indicating moderate hazard evaluation. Questionnaires distributed todwellers around the dumpsite also showed that 83.6% of those interviewed agreed that the present man-agement of the dumpsite is poor while 81.8% supported rehabilitation of the dumpsite. Hence, recon-struction of the Igbatoro dumpsite to an endurable and controlled landfill is hereby recommended.
