The International Groundwater Resources Assessment Centre (IGRAC) hosts an interactive map that compiles over a thousand managed aquifer recharge (MAR) case studies from over 50 countries. The MAR Portal is one of several groundwater related maps within the IGRAC global groundwater information system.

The California Department of Water Resources has created an interactive map that shows geospatially referenced groundwater levels, groundwater table elevation, and subsidence in California.

The map includes:

The Idaho Department of Water Resources provides an interactive map with information on geothermal wells and springs in the state. Wells and springs are split into low-temperature (85 to 212 degrees fahrenheit) and high-temperature (above 212 degrees) groups.

Users can click on individual wells and springs to find more information, including temperature, discharge, and use.

The map also includes information about groundwater vulnerability across the state.

Alberta Energy (a ministry of the Government of Alberta) provides an interactive map with basic information on coal resources in Alberta. The map includes:

Alberta Energy (a ministry of the Government of Alberta) provides an interactive map with basic information on oil sand regions (and oil and gas more broadly) in Alberta. The map includes:

The U.S. Geological Survey provides an interactive map that allows users to view changes in groundwater levels and associated land subsidence since 1977 in the Houston-Galveston area.

The map uses annual data from over 800 wells, and shows changes in water levels in three major aquifers in the region: the Chicot, Evangeline, and Jasper aquifers.

The Delaware Geological Survey provides an interactive map with a large amount of information about groundwater in the state, including:

The Delaware Sea Level Rise Inundation map shows how various extents of future sea level rise (0.5, 1.0, and 1.5 meters) would affect flooding in coastal Delaware. For each scenario, users can see the areas that would be flooded during an average higher tide (Mean Higher High Water). The map does not include the effects of erosion, subsidence, or future construction.

Users can search by location to see the effects on individual areas.

The Missouri Department of Natural Resources provides an interactive map of industrial mineral mines (stone, aggregates, and clay) in the state. By clicking on individual sites or areas, users can find a variety of information, including:
