Passage: Desalination is an artificial process by which saline water (generally sea water) is converted to fresh water.  The most common desalination processes are distillation and reverse osmosis.  Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. It is usually only economically practical for high-valued uses (such as household and industrial uses) in arid areas. However, there is growth in desalination for agricultural use, and highly populated areas such as Singapore or California. The most extensive use is in the Persian Gulf.
