Abstract: Kizildere, which is the only commercial geothermal power plant in Turkey and located in Buyuk Menderes Graben in south-west Turkey, discharges annually 6 million tonnes of wastewater into the Buyuk Menderes river, creating environmental pollution. Currently, the wastewater, which includes up to 24 mg/l boron, is discharged into the river at a rate of 750–1500 tonnes per hour. The temperature of the wastewater is approximately 1401°C. The water quality of Buyuk Menderes river is very important for the environment and aquatic life. Reinjection seems to be the only possible solution to this environmental problem.

Keywords: boron pollution; geothermal wastewater; Kizildere geothermal field; Menderes river; Turkey.
