Abstract : Groundwater is a vital natural resource, critical for human health and industrial progress. However, Nigeria's rapid urbanization and poor waste management infrastructure have resulted in serious groundwater pollution, endangering the environment and human health. The purpose of this study was to investigate the intricate interactions between groundwater quality and trash disposal methods in Uguwaji, a region inside the Enugu Metropolis. The research examines the quality levels of the groundwater collected from the dump site and from the free area (control) of the upper stream, middle stream and downstream sampling sites using a stratified random sampling technique that includes water sample analysis in the laboratory for physical and chemical water properties. The findings show notable differences in water quality between waste dump and control sites as well as between other sampling sites. Significantly, compared to the control site, the waste disposal site shows lower mean rankings for total dissolved solids, pH, salinity, nitrite, and phosphate, as well as electrical conductivity, suggesting possible contamination. Meaningful relationships between water characteristics was also observed. For example, electrical conductivity, total dissolved solids, and salinity are significantly positively correlated. These findings highlight the need for focused environmental conservation and healthcare initiatives to ensure the population's well-being and the urgency of implementing sustainable waste management strategies to address groundwater pollution in Uguwaji and similar urban areas in Nigeria.
