  Potable water is available in almost all populated areas of the Earth, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commonly obtained include springs, hyporheic zones and aquifers (groundwater), from rainwater harvesting, surface water (from rivers, streams, glaciers), or desalinated seawater.
  
  For these water sources to be consumed safely, they must receive adequate water treatment and meet drinking water quality standards.
  
  An experimental source is atmospheric water generators.
  
  Springs are often used as sources for bottled waters.
