USGS Ground-Water DataThe U.S. Geological Survey provides unbiased, timely, and relevant data on the ground-water resources of the Nation:
Ground-Water LevelsUSGS Ground-Water WatchThe Ground-Water Watch web sites group related wells and data from National Water Information System (NWIS) active well networks and provide basic statistics about the water-level data. Networks include the Active Ground-Water Level Network, the Climate Response Network, and the Real-Time Ground-Water Level Network. USGS Online Ground-Water Data (NWIS)The National Water Information System (NWIS) ground-water database consists of more than 850,000 records of wells, springs, test holes, tunnels, drains, and excavations in the United States. USGS Annual Water Data ReportsWater resources data are published annually. These archival products supplement direct access to current and historical water data provided by NWISWeb. Ground-Water Level Data by StateSources of ground-water level data, by State: AquifersNational Aquifer Code Reference ListThe National Aquifer Code Reference List provides the National Water Information System (NWIS) codes used for the principal U.S. aquifers and information about the aquifers. Ground Water Atlas of the U.S.The Ground Water Atlas of the U.S. provides a summary of the most important information available for each principal aquifer. National Atlas - AquifersNational Atlas map layers include information on the principal aquifers of the United States, viewable online as or downloadable GIS data sets
National Cooperative Geologic Mapping ProgramThe National Cooperative Geologic Mapping Program (NCGMP) provides accurate geologic maps and three-dimensional framework models that help to sustain and improve the quality of life and economic vitality of the Nation and to mitigate natural hazards. Water UseWater Use in the U.S.The USGS compiles water-use information aggregated at the county, state, and national levels. Every five years, data at the county level are compiled into a national water-use data system and state-level data are published in a national circular.
Ground-Water Quality DataUSGS Water-Quality Data for the Nation - National Water Information System (NWIS)The USGS National Water Information System (NWIS) water-quality database is a compilation of over 4.4 million historical water quality analyses across the Nation.USGS Water Quality DataThe USGS collects, analyzes, archives, and disseminates data and information describing the quality of the Nation's surface-water and ground-water resources. Visit the USGS Water-Quality Information web site to find about more about what USGS water-quality data are available. Water-Quality Web ServicesWeb services allow for the automated sharing of USGS and USEPA water-quality monitoring data.
