General Notes: *Median value gives the value for the "average" county for this metric, the 50th percentile of all counties reporting data. **Water used in the process of generating electricity with steam-driven turbine generators. Term used in previous water-use circulars to describe the combined public-supply deliveries to thermoelectric-power plants and self-supplied thermoelectric-power withdrawals. For 2000 and 2005, thermoelectric-power water use refers only to self-supplied thermoelectric-power withdrawals. Thermoelectric power was subdivided into fuel types of fossil fuel, geothermal, and nuclear from 1985-1995 and into cooling types of once-through and recirculating from 2000 to present. Water that contains less than 1,000 milligrams per liter (mg/L) of dissolved solids. Generally, water with more than 500 mg/L of dissolved solids is undesirable for drinking and many industrial uses.
