Different Water Types
Fresh, Brackish, and Salt Water
Fresh Water
Fresh water is water that is found in nature and does not contain salt. It can be found in glaciers, rivers, lakes, ponds, icebergs, and underground in aquifers.
Brackish Water
Brackish water is found where salt water and fresh water mix. It contains a lower concentration of salt than salt water does but is not comletely fresh water. This water is generally located in estuaries, brackish fossil aquifers, and marshes where the river meets the ocean.
Salt Water
Salt water (also known as saline water) contains 3-5% salt and is found in oceans around the world. Because of this high salt concentration, oceans are home to plants and animals that can't be found anywhere else. Salt water makes up 97% of the water found on earth.
