The residence time is the average time a substance spends within a particular volume of space. For example, the residence time of water within groundwater is about 10,000 years. For A detailed picture click Here!!
The water cycle is the process that all water takes. It includes precipitation which is the falling of water in any form to earth, infiltration which is the process in which water is absorbed into the soil (it may also flow off the surface called surface runoff), evaporation or transpiration which is either when water is heated and turns into water vapour or when plants use the water and give it off as water vapour, condensation which is when the water vapour cools and forms clouds. This process is then repeated over and over again. For More Information click HERE!!

Water useage rates are nearly double that of the population growth and with the population rising in millions every year, fresh water supplies are becoming scarce! It is said that by 2025 over a third of the world's population will be heavily affected by water shortages!! For more information and water shortages and graphs click Here!
Desalination or desalinization refers to any of several processes that remove the excess salt and other minerals from water in order to obtain fresh water!! For more information on this subject click Here!
