USGS Water Science Centers are located in each state.

USGS Groundwater Data

The U.S. Geological Survey provides unbiased, timely, and relevant data on the groundwater resources of the Nation:

• Groundwater Levels
• Aquifers
• Water Use
• Groundwater Quality Data
• GIS
• Local Groundwater Data
• Other Sources of Water Data

Groundwater Levels

USGS Groundwater Watch

The Groundwater 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 Groundwater Level Network, the Climate Response Network, and the Real-Time Groundwater Level Network.

USGS Online Groundwater Data (NWIS)

The National Water Information System (NWIS) groundwater 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 Reports

Water resources data are published annually. These archival products supplement direct access to current and historical water data provided by NWISWeb.

Groundwater Level Data by State

Sources of groundwater level data, by State:

• USGS Water Science Center in Your State
• Arizona Groundwater Conditions Interactive Map

Aquifers

National Aquifer Code Reference List

The 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 - Aquifers

National Atlas map layers include information on the principal aquifers of the United States, viewable online as or downloadable GIS data sets

• National Atlas map layer - Aquifers of Alluvial and Glacial Origin
• National Atlas map layer - Principal Aquifers

National Cooperative Geologic Mapping Program

The 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 Use

Water 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.

• Estimated Use of Water in the U.S. in 2000 (Circular 1268)
• National Atlas map layer - Estimated Use of Water in the U.S. in 2000
