Özet
As urbanization and population increase in the megacity, there is a need for engineering
intervention and strategic monitoring of groundwater around landfills for environmental
sustainability, pollution reduction and public health. This study evaluated water’s physical
and chemical parameters in wells and boreholes near the Olusosun landfill in Lagos State
to determine how they impact groundwater quality. An Atomic Absorption Spectrometer
(AAS) was used to evaluate groundwater samples obtained from five locations within the
dump site. Some water parameters, such as dissolved oxygen (DO), iron (Fe), lead (Pb),
manganese (Mn), and magnesium (Mg), had concentrations that were higher than the WHO,
NESREA, and Nigerian Standard for Drinking Water Quality (NSDWQ) standard limits in
some sampling sites, with mean concentrations of 0.33 mg.L-1, 0.04 mg.L-1, 0.74 mg.L-1,
and 0.74 mg.L-1, respectively. A small amount of lead was identified in the groundwater
of the study area. A major source of air and groundwater pollution, the Olusosun landfill
has a detrimental impact on the health of those who live there. Solid waste, groundwater
interactions, and contaminated migration into the nearby neighbourhood were studied. It was
observed that the degradation of waste products in dump sites releases harmful leachate into
the groundwater. Even though some heavy metal concentrations in the study area are still
within WHO, NESREA, and NSDWQ standard limits, investigations and further monitoring
should be conducted regularly to assess the concentrations of heavy metals in groundwater.
