Evaluation of Physicochemical and Metallic Properties of Covered and Uncovered Groundwater Wells in Ado-Ekiti, Nigeria

This study presents the physicochemical and heavy metal analyses of water samples obtained from covered and uncovered wells in the selected areas of Ureje, Damola, and Erifun. The results of the physicochemical analysis, including parameters such as color (colourless), pH (۵.۴۲-۶.۵۰), electrical conductivity (۱۶۹-۲۳۸ μS/cm), total dissolved solids (۱۴۵-۲۰۲ mg/L), temperature (۲۶.۷۰-۲۷.۰۰ ۰C), total hardness (۲۸.۰۰-۵۶.۰۰ mg/L), calcium hardness (۱۱.۲۲-۲۲.۴۵ mg/L), magnesium hardness (۱۶.۷۸-۳۳.۵۵ mg/L), sulphate (۸.۹۰-۳۴.۰۰ mg/L), nitrate (۱.۲۰ to ۴.۸۶ mg/L), chloride (۷۸.۱۰ -۱۲۷.۸۰ mg/L), and alkalinity (۲۰۰-۵۶۰ mg/L). The findings suggest variations in these parameters between covered and uncovered wells, emphasizing potential differences in water quality and composition. Insights into the concentrations of heavy metals, includes iron (Fe) (۰.۱۳۳ - ۰.۳۸۷ ppm), lead (Pb) (۰.۰۲۲ - ۲۶۱ ppm), copper (Cu) (۰.۰۱۳ - ۰.۲۳۴ ppm), chromium (Cr) (ND - ۰.۰۲۱ ppm), and cadmium (Cd), with the "not detected" (ND) notation indicating absence in all the samples. The data highlights potential heavy metal contamination in the water sources, particularly in the uncovered wells, raising concerns about the safety and quality of the water supply in the studied locations. These findings emphasize the importance of regular monitoring and appropriate management strategies to ensure the provision of clean and safe drinking water to the communities in these areas.
