Dumpsite

Dumpsite utilization for municipal solid waste disposal produces leachate which is a threat to groundwater resources. The study was aimed at determining the suitability of groundwater for drinking and domestic usages using physical, chemical and microbial indices, with a view to assessing the vulnerability of boreholes close to dumpsite to groundwater pollution. The results showed that except for pH and lead, the concentrations of other physico – chemical parameters were within acceptable limits of NSDWQ and WHO.

Comparative assessment of the soil and vegetation in a municipal dumpsite at Iguomo, Benin City, Nigeria at different distances from the dumpsite was carried out. An area of 30m2 was marked out and divided into three plots of 10 m2 each and these were designated as plots A, B and C. An area of 10 m2 was also taken at a distance of 100m away from the dumpsite, it served as the control plot or plot D. Population sampling was done to determine the species diversity across the plots. Soil samples were collected from each plot and microbial and physico-chemical analyses were carried out.

Refuse dumpsites often contain materials capable of polluting surrounding soils. In this study, the spatial distribution of metals in soils of refuse dumpsites in three urban towns (Ughelli, Sapele, Orhuwhorun) in Delta State, Nigeria were examined. Soil samples were collected from three dumpsites in the aforementioned towns at depths 0-15 cm, 15-30 cm and 30-45 cm, respectively.
