My neighbor's driveway with some water on it... not very exciting, but it is an excellent example of how groundwater flows underground and can seep back to the land surface. This simple process demonstrates one of the basic aspects of the water cycle.

Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.

Total saline water withdrawals by State, 2015

As the chart shows, the use of saline water, and freshwater, also, has been trending downward since peaking in 1980. Of interest, from 1950 to 1975 the use of saline water increased at a much higher rate than freshwater use.

Two pie charts, showing total water withdrawals (fresh and saline), and saline water withdrawals, for certain categories of water use, for year 2015.

Source and Use of Freshwater in the United States, 2015

This diagram uses a "cylinder and pipe" layout to show the source (surface water or groundwater) of the Nation's freshwater and for what purposes the water was used in 2015. The data are broken out for each category of use by surface water and groundwater as the source.

Der Wasserkreislauf für Kinder

Du denkst vielleicht, jeder Regentropfen, der vom Himmel fällt, oder jedes Glas Wasser, das du trinkst, ist nagelneu, aber das asser ist schon immer da, und es ist Teil des Wasserkreislaufs.

Hot springs can occur in many parts of the world. The water is hot not due to climate, but rather due to geothermal activity underground, such as volcanic activity or active hydrothermal heating from hot material in the ground. Hot springs result from water heated by underground geothermal activity finding its way to the land surface. 

Land subsidence in California - Approximate location of maximum subsidence in the United States identified by research efforts of Dr. Joseph F. Poland (pictured). Signs on pole show approximate altitude of land surface in 1925, 1955, and 1977. The site is in the San Joaquin Valley southwest of Mendota, California.
