Abstract
Continuous burning of wastes at municipal dumpsite constitutes environmental hazards to the surrounding communities and human health. Leachate emanating from these dumpsite infiltrate the soil and sometimes get run off to nearby water resources available for domestic, agricultural and industrial use. This study is to evaluate the quality of groundwater,surface water and soil samples collected in the vicinity of an open municipal dumpsite: Ajakanga solid-waste municipal dumpsite in Oluyole LGA, Ibadan, Oyo State. Sixteen water samples (groundwater and surfacewater samples) and four top soil samples were collected within the vicinity of the dumpsite. The samples were analyzed for physiochemical quality check, potentially toxic elements (PTEs) concentrations and microbiological analysis. The physiochemical properties of the samples were determined using standard method of analysis. The value of physiochemical properties of water and soil samples were below the permissible limit of WHO and NESREA. Except some parameters like TSS, Electrical conductivity, Nitrates, Nitrite in well water and stream water; and chloride in soil sample are above the WHO and NESREA limit. The potentially toxic elements (PTEs) identified are Zn, Cu, Mn, Pb, Fe, Cr, Ni and their concentration were determined using Atomic absorption spectrophotometer. The values obtained for these parameters are within acceptable ranges of WHO except Cu, Mn and Cr which are slightly above WHO limit. The microbial analysis of the samples showed microbial loads of high counts above the WHO limit due to biodegradation and decomposition of solid or food wastes, and presence of feaces on the dumpsite. The parameters checked were E. Coli, Total Coliform, Total Heterotrophic. However, bio-accumulation and bio-magnification of these parameters can poses a dangerous health challenges to the environment and life in the communities closed to the dumpsite.
