Interactive map of groundwater monitoring information in the United States

The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.

Water as One Resource

This course provides an overview of how groundwater and surface water interact, what the implications of these interactions on water resources are, and how water can be more effectively managed if an understanding of these interactions is incorporated.

The course presenters are Ken Bradbury from the Wisconsin Geological and Natural History Survey, William A. Alley from the National Groundwater Association, and Thomas Harter from the University of California, Davis.

Desalination as a Source of Fresh Water

Fresh water is an increasingly scarce resource in an increasingly populous and water-intensive world. Maintaining an adequate supply of fresh water both nationally and globally will be one of the largest challenges of the 21st century. Desalination of salty water, from both the ocean and the ground, represents a huge potential source of fresh water. The development of this resource requires a combination of geoscience, engineering, waste management, policy, and community outreach and participation.
