Ground Water at USGS

Ground-Water Availability in the United States was published in July 2008 by the USGS. You can now download the 79-page pdf.

This report provides a wealth of information on our most important resource. From USGS: "This report examines what is known about the Nation's ground-water availability and outlines a program of study by the U.S. Geological Survey Ground-Water Resources Program to improve our understanding of ground-water availability in major aquifers across the Nation. The approach is designed to provide useful regional information for State and local agencies who manage ground-water resources, while providing the building blocks for a national assessment. The report is written for a wide audience interested or involved in the management, protection, and sustainable use of the Nation's water resources."

This should prove valuable to most lifelong learners.
