Aquifers: Ground Water Atlas of the United States
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.
