Ground Water
https://en.wikipedia.org/wiki/Groundwater
“Ground Water is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.”
The USGS conducts ongoing surveys, investigations, and research on ground water throughout the United States. One important product of this work is the Ground Water Atlas of the United States, available here: https://water.usgs.gov/ogw/aquifer/atlas.html
“The Ground Water Atlas of the United States, USGS Hydrologic Atlas 730 (Miller, 2000), describes the location, hydrologic characteristics, and geologic characteristics of the principal aquifers throughout the 50 States, Puerto Rico, and the U.S. Virgin Islands. The groundwater information summarized in the Atlas was collected over many years by the USGS and other partner agencies and published in 2000. The Atlas provides key descriptive information in a regional and national context.
