FileGroundwater and Surface Water - A Single Resource by admin — last modified May 02, 2007 05:00 PM

FileGroundwater Level Monitoring and the Importance of Long-Term Water-Level Data (Alley/Taylor) by admin — last modified May 02, 2007 04:55 PM
U.S. Geological Survey Circular 1217 Charles J. Taylor William M. Alley Groundwater is among the Nation’s most precious natural resources. Measurements of water levels in wells provide the most fundamental indicator of the status of this resource and are critical to meaningful evaluations of the quantity and quality of ground water and its interaction with surface water. Water-level measurements are made by many Federal, State, and local agencies. It is the intent of this report to highlight the importance of measurements of ground-water levels and to foster a more comprehensive and systematic approach to the long-term collection of these essential data. Through such mutual efforts, the Nation will be better positioned in coming decades to make wise use of its extensive groundwater resources.
FileEvolving Issues and Practices in Managing Ground-Water Resources by admin — last modified May 02, 2007 04:32 PM
Circular 1247 U.S. Department of the Interior U.S. Geological Survey Hydrologic stresses throughout the 20th century and presently (2003) have caused the depletion and degradation of our Nation’s vital ground-water resources in many areas. Management strategies have been and are being implemented to optimize use of our ground-water resources with respect to achieving sustainability while mitigating the consequences of future withdrawals. The seven case studies presented herein show how the U.S. Geological Survey (USGS) in cooperation with local, State and other Federal agencies, as well as the private sector, have addressed some of the complexities of ground-water management using scientifically-based hydrologic studies and hydrologic monitoring. It is clear that the managed conjunctive use of our combined ground-water and surface-water supplies, and the artificial recharge of our ground-water systems present both challenges and opportunities. How well we manage these options depends upon best science practices, improved understanding of the resources, and the informed consensus of all stakeholders. s/s

Report to the US Congress - October 2006 Department of State Publication 11345 Bureau of Oceans and International Environmental Scientific Affairs Printed June 2006 7 This report contains an introduction, an outline of the global water situation, the U.S. foreign policy context, past and current USG activity in the sector, and a strategy for moving forward. Annex A provides an overview of U.S. Agencies working on water; Annex B provides an overview of USAID funding on water. As examples of how some of these water issues may be raised in regional and country-level strategies, Annex C presents more information on strategic planning of USAID’s water and sanitation activities in Africa; Annex D provides the ECO Asia strategy for USAID’s regional mission in Bangkok; and Annex E provides the recentlydeveloped Blue Revolution Initiative by USAID’s Bureau for Asia and the Near East.
FileAssessing Ground-Water Vulnerability to Contamination: Providing Scientifically Defensible Information for Decision Makers by admin — last modified May 02, 2007 04:26 PM
By Michael J. Focazio, Thomas E. Reilly, Michael G. Rupert, Dennis R. Helsel This report provides an overview of some of the common approaches used to scientifically determine the important factors controlling the vulnerability of ground-water resources to contamination. In addition, the report discusses the strengths and weaknesses of the various approaches as sources of scientifically defensible information for the water-resource management decision-making process. Descriptions of scientifically defensible methods are supported by example studies that have been conducted by the U. S. Geological Survey (USGS) often in cooperation with local, state, and regional water-resources agencies.
FileGround Water in Freshwater-Saltwater Environments of the Atlantic Coast (Barlow) by admin — last modified May 02, 2007 03:44 PM
Paul M. Barlow U.S. Department of the Interior U.S. Geological Survey Ground water is a vital resource for communities and ecosystems of the Atlantic coastal zone. Ground-water withdrawals for public supplies, agriculture, industry, and other uses in coastal counties from Maine to Florida were about 7.7 billion gallons per day in 1995, and in many coastal communities, ground water is the primary or sole source of drinking-water supply. Ground water sustains the flow of coastal streams and rivers and is a source of freshwater to coastal ponds, wetlands, and other coastal ecosystems. The U.S. Geological Survey (USGS) has a long history of conducting scientific studies of ground water in the Atlantic coastal zone. This Circular draws heavily on the body of scientific knowledge developed over several decades of USGS monitoring and studies.
