The Aba River flows through Abia State in southeastern Nigeria and forms part of the Imo River drainage system before ultimately discharging into the Atlantic Ocean. The river has historically supported domestic water supply, agriculture, fishing, and industrial activities within Aba and surrounding communities. Rapid urbanisation and industrial development around Aba have resulted in increasing pressures on the river. Studies have reported elevated concentrations of nutrients, heavy metals, suspended solids, and microbial contaminants in some reaches receiving untreated mu
