A large volume of water produced from oil and gas recovery operations is usually reinjected into the subsurface through disposal wells. A portion of the produced water, after treatment, could be suitable for supplementing freshwater needs of power generation plants. Utilization and treatment requirements of produced water highly depend on water quality. This study investigates the feasibility of using produced water from Enhanced Oil Recovery (EOR), Coal-Bed Methane (CBM) operations, and coal mines located in the Illinois Basin as cooling/process water in the coal-based power generation industry. Water samples were collected from selected oilfields, CBM sites, and coal mines and analyzed for pH, TDS, TSS, alkalinity, turbidity, ammonia, TPH, TOC, and various cations and anions. Water quality parameters will be presented and their implications on the treatment requirements will be discussed.
