(Freshwater- Brackish Water - Saltwater)

Freshwater

Fresh water has low concentrations of dissolved salts (usually less than 1%) and other total dissolved solids.

Natural fresh water includes ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, streams, underground groundwater in aquifers and underground streams.

The source for almost all fresh water in precipitation.



Brackish Water

Brackish Water (0.05% – 3%) is more salinity than fresh water, but not salt water.
Usually this water is found in fossil aquifers or when fresh water and salt water mix like in estuaries. It is also found in mangroves and marshes.

Brackish water can also be made by man from civil engineering projects that cause dikes and flooding of coastal marshlands.

This water is hostile towards most terrestrial plant species and without the management of it, the environment will be damaged.


Saltwater

Also know as Saline water, it has a concentration of salt between 3% – 5%. Salt water is most commonly found in the ocean. Salt water is a geological term that refers to naturally occurring solutions containing large concentrations of dissolved, inorganic ions. Saltwater can also seep into the underground water supplies contaminating the aquifer. Saltwater is "mined" for their economically useful minerals.
