This study assesses the water quality of a mined quarry pit in COPEK Quarry, Ikere, Ekiti State, Nigeria. The research aimed to determine the physico-chemical parameters and inorganic ion concentrations in quarry pit water, river water, and borehole water. Water samples were collected from seven locations and analyzed for pH, electrical conductivity, turbidity, total hardness, bicarbonate content, and concentrations of calcium, magnesium, iron, zinc, chloride, phosphate, and nitrate ions. The results showed varying levels of these parameters, with some exceeding World Health Organization (WHO) permissible limits. The pH ranged from acidic to alkaline (4.9-8.4), while electrical conductivity indicated moderate to good conductivity (182.1-498 μs/cm). Total hardness ranged from soft to very hard water (52.60-172.30 mg/L). The presence of coliform bacteria in some samples indicates potential health risks. The study highlights the need for regular monitoring and management of water resources around mining areas to mitigate environmental and health impacts.
