Abstract :
This study aimed to assess the impact of solid waste on the physical, chemical, and biological characteristics of underground water in some areas of Ikole town in Ekiti State, Nigeria. The study was conducted by collecting groundwater samples from Otunja and Asin, which were contaminated by domestic wastewater. The samples were analysed using conventional tests, infrared spectrophotometer (IR), and atomic absorption spectrophotometer (AAS) equipment to measure pollutants concentration of groundwater. The study also compared the characteristics of a control well with the underground water at the dumping sites and evaluated the effect of the solid wastes on each well by comparing the quality to WHO standard. The results showed that the presence of solid waste in the dumping sites had a significant impact on the quality of groundwater, which was contaminated with pollutants such as turbidity, pH, alkalinity, biochemical oxygen demand, total solid, suspended solid, and microbial analysis. The study recommends the implementation of proper waste management practices to prevent groundwater contamination and protect human health.
