Different Types of Water

By Tyson Spencer

Brackish Water

Brackish water is saltier than fresh water but not as salty as sea water. Brackish water can result from sea water mixing in with fresh water. Most occur in areas where a river meets the sea and civil engineering projects can produce brackish water. For example, the Caspian Sea and Black sea contain brackish water.

Fresh Water

Fresh water contains less than 1000 milligrams of salt. It makes up 3% of the water supply in the world and permanent ice makes up 2% of the 3%. Ground water makes up 30% of the total fresh water supply, and you can find fresh water in lakes, rivers, swamps, and marshes. The Great Lakes in the U.S. are the largest surface fresh water system in the world.

Salt Water

Salt Water is water from the sea or ocean that has a salinity of 3.5%. It is more denser than fresh water and salt water makes up 96.5% of water on Earth. Salt water's freezing point is lower than pure water but the boiling point is higher.
