The Connecticut Geological Survey's (CGS) map of surficial aquifer potential shows the areas with high potential for groundwater supply based on the thickness of coarse-grained deposits. Colors on the map indicate the thickness of coarse-grained deposits and the thickness of fine-grained deposits where they occur over coarse-grained sediments.

The U.S. Geological Survey's (USGS) Mineral Resources Program's interactive Geologic Map of U.S. States provides a large amount of information on geology, natural resources, and environmental data for every U.S. state, including:

• Surface and bedrock geology
• Mineral resources
• Geochemical and geophysical data
• Water monitoring sites
• Partial soil and land use data

All of the maps are also available as Google Earth files that can be downloaded and used on personal computers and mobile devices.
