Desalination | U.S. Geological Survey
Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water …

Explainer: How is water cleaned up for drinking
Explainer: How is water cleaned up for drinking. Most people get their drinking water from lakes, rivers or groundwater aquifers. But before it flows out the tap, cities will typically treat the water in big industrial plants, as here, to purify it. People are used to turning the handle on a sink and seeing a stream of clear water pour forth.

Wastewater Treatment Water Use | U.S. Geological Survey
Wastewater treatment. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water. "Primary treatment" removes …
