Whatever the definition, there is a great amount of salty water worldwide that cannot be used without desalination. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Refractometers measure the way light bends through the water to determine salinity. It can be measured effectively with two different metrics: Brackish water has a salinity between 0.5 and 2 ppt of dissolved salts with a specific gravity between 1.0004 and 1.0015 for water at 77 degrees Fahrenheit.
