Environmental Assessment of Solid Waste Management in Nigeria: A case study of Ikere Ekiti, Ekiti state
2014
Following apparent increase in population and with a corresponding increase in solid waste generation in Ikere Ekiti, Ekiti State
of Nigeria, this study was initiated to assess the level of environmental pollution and potential impact of wastes. Health risk assessment
was determined by a survey of existing facilities for solid waste management. Microbiological and physicochemical analyses of
decomposing waste, soil, and well water were carried out using standard procedures. Prevalent bacteria besides fungi isolated from solid
waste, soil, and well water were Staphylococcus 36(25.85%), Escherichia 49 (19.61%), Pseudomonas 40 (34.11%) and each of
Shigella/Salmonella 32 (21.82%), respectively. Solid waste followed by soil, had the highest count at 5% level of probability. These
findings, coupled with the high aerial bacterial counts, indicate a high risk of microbial infection from the waste dump. There is also a
high risk of diseases and potential destruction of biodiversity from toxic chemicals from the waste. All the physicochemical attributes
determined were within the consent limits except the heavy metal levels in leachate. In view of the economy and high technology
involved, it is recommended that both governments and private sectors should review the present waste management practice in relation
to traditional methods.
