Where does the clean water flowing out of your kitchen faucet come from? In Clarksville, Tennessee, it is pumped from the Cumberland River to the water-treatment plant. And after you use the water, it goes to the wastewater-treatment plant. At both facilities, plant operators control processes and equipment that remove pollutants from the water. They take water samples and read meters and gauges. After examining this data, they adjust equipment or the dosing of chemicals to ensure that the water is safe. And that's just a typical day.
