Cooling water discharges comprise the largest percentage of steel mill effluents and are usually 10°-15°F warmer than the water withdrawn from the source of supply. The rise in temperature is the only change in water used for indirect cooling and is usually not significant if the effluent is discharged into a reasonably large stream.
