Author(s): Akinwumi Isaac Tope, Francis Olusegun Oladeji, Omotoso Ayodele Jacob


The escalating urbanization and industrialization in Osogbo, Southwestern Nigeria, have given rise to heightened apprehensions regarding the integrity of groundwater quality adjacent to municipal solid waste dump sites. This study endeavors to conduct a thorough and holistic evaluation of the physico-chemical parameters of groundwater in the proximity of these waste disposal sites. The investigation delves into the potential environmental repercussions and health risks associated with contemporary waste disposal practices in the region.

The comprehensive assessment encompasses a multifaceted analysis, with a primary focus on discerning the intricacies of pH levels, concentrations of heavy metals, and the presence of organic pollutants in groundwater. These parameters serve as critical indicators of water quality, reflecting the potential contamination emanating from anthropogenic activities. The study strategically selects sampling sites around municipal solid waste dump locations in Osogbo, ensuring a nuanced representation of the diverse groundwater conditions prevalent in the region.

Preliminary results illuminate notable disparities in pH levels, indicating a potential influence from waste disposal practices. The identification of elevated concentrations of heavy metals, including lead and cadmium, raises alarms about the possible health implications for local communities reliant on this groundwater source. Furthermore, the detection of organic pollutants underscores the multifaceted nature of contamination, necessitating a comprehensive understanding of the pathways through which pollutants infiltrate groundwater.

The findings from this study serve as a clarion call for urgent intervention and strategic planning to address the challenges posed by improper waste disposal. The implications extend beyond environmental considerations to encompass public health and sustainable development. The elucidation of these physico-chemical parameters contributes vital insights for policymakers, environmental agencies, and community stakeholders, guiding the formulation of effective waste management strategies tailored to the unique conditions of Osogbo, Southwestern Nigeria.
