The soil samples were collected 10m away from the edge of Eliozu dumpsite at four different locations labelled PH/01, PH/02, PH/03 and PH/04 at depths interval of 0.50m, 1m, 1.5m, and 2m respectively. Sample were collected with a stainless steel hand auger and analysed to determine the effect of Leachate on soil physicochemical parameters. Parameters analysed for were: PH, Total Organic carbon, (TOC), nitrate, phosphate and sulphate and heavy metals such as chromium, cadmium, copper, lead, nickel, zinc and iron were analysed using Atomic Absorption Spectrophotometer (AAS). While mean value, standard deviation were analyzed using E- view software 8.0. The results of the analysis showed that some of the parameters exceeded the maximum permissible limits of WHO permissible limit. The parameters that exceeded permissible limits were nickel, chromium, copper, cadmium and Lead. Parameters such PH, nitrate and zinc were below WHO permissible limit. For those parameters that above WHO permissible poses threat to groundwater, biological food chain and the environment. Consequently, some of the parameters that did not exceed permissible limits might become hazardous to the environment in the future if the landfill is not properly engineered to handle leachate leakages to the subsoil.
