Heavy metals constitute a major threat to humans due to the fact that they unlike some other pollutants are not biodegradable. This study aims at comparing heavy metals presence in two waste dumpsite in relating to its environs; Gbagede community in Ifelodun Local Government of Kwara State and Ilokun community in Ifelodun Local Government area of Ekiti State hosts the dumpsites in this research study. The dumpsite is located within 0- 50m for Gbagede and 50m-100m in Ilokun. Randomly collected soil and water samples from different areas of Gbagede and Ilokun dumpsite as well as the community were analyzed for heavy metals using AAS. The trend of metal in soil are GD>ID>GCOM > ICOM for Cd, Mn, Fe, Zn and ID>ICOM>GD>GCOM for Cu as revealed in the result. Higher level of Cd, Mn, Cu and Fe was recorded at the various dumpsites for Cd 2.350 ± 0.016mgKg-1, 1.316 ± 0.062 mgKg-1 in both Gbagede and Ilokun dumpsite respectively found higher than the standard given as 0.41 mgKg-1, Mn analysis gave mean values of 1865.500 ±1.323mgKg-1 (Gbagede dumpsite), 579.667 ± 3.329mgKg-1 (Ilokun dumpsite) for both Gbagede and Ilokun dumpsite are higher than the control and standard used in the analysis, also mean levels of Cu for Ilokun dumpsites and the community 39.00 ± 0.408 mgKg-1 and 39.33 ± 0.2357are higher than the control sample (11.000 ± 0.000) and also the world soil average (38.90 mgKg1), it was observed that Cu concentrations in Gbagede dumpsite and its community 35.167 ± 0.577mgKg-1) and 31.500 ± 0.500 mgKg-1) are within the world-soil average use as standard in the study. It was observed that the Gbagede dumpsite has higher level of observed metals compare to Ilokun dumpsite and its adjourning communities.
