WebOscar E. Meinzer's discussion of the occurrence of groundwater in the United States (1923, The Occurrence of Ground Water in the U.S. with a Discussion of Principles, USGS Water-Supply Paper 489) is a classic in the science of groundwater and geology. It is an excellent reference for the broadest possible view of the principles of the science. Web6.5 Groundwater. Groundwater is stored in the open spaces within rocks and within unconsolidated sediments. Rocks and sediments near the surface are under less pressure than those at significant depth and therefore tend to have more open space. For this reason, and because it is expensive to drill deep wells, most of the groundwater that is ... slow walk calories burned
