Fresh water

Fresh water (adj. freshwater or fresh-water) is water that contains only minimal quantities of dissolved salts, especially sodium chloride, thus distinguishing it from sea water or brackish environments.

Fresh water derives from the precipitation of atmospheric water vapor, either directly or by the melting of snow or ice.

Most inland lakes and non-tidal stretches of rivers are fresh water.

Access to fresh water is a critical issue for the survival of many species, especially in desert areas.
