The Ground Water Atlas of the United States presents a comprehensive summary of the Nation's ground-water resources, and is a basic reference for the location, geography, geology, and hydrologic characteristics of the major aquifers in the Nation. The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. Results of the U.S. Geological Survey's Regional Aquifer-System Analysis Program, a systematic study ofthe Nation's major aquifers, were used as a major, but not exclusive, source of information for compilation of the Atlas.The Atlas, which is designed in a graphical format that is supported by descriptive discussions, includes 13 chapters, each representing regional areas that collectively cover the 50 States and Puerto Rico. Each chapter of the Atlas presents and describes hydrogeologic and hydrologic conditions for the major aquifers in each regional area. The scale of the Atlas does not allow portrayal of minor features of the geology or hydrology of each aquifer presented, nor does it include discussion of minor aquifers. Those readers that seek detailed, local information for the aquifers will find extensive lists of references at the end of each chapter.An introductory chapter presents an overview of ground-water conditions Nationwide and discusses the effects of human activities on water resources, including saltwater encroachment and land subsidence.
This project has been carried out with support from Sarah Pillsbury and Brandon Kernen of the New Hampshire Department of Environmental Services (NHDES). The authors would like to thank Johnna McKenna of NHDES for providing the Water Distribution and Sewer Collection Areas geographic information systems data, Linda Thompson of New Hampshire Drinking Water and Groundwater Bureau for providing a copy of the Drinking Water database, Frederick Chormann of the New Hampshire Geological Survey/NHDES for providing a copy of the state water-use registration database (WATUSE), and Daniel Dudley of NHDES for providing a copy of the National Pollutant Discharge Elimination System (NPDES) wastewater facility database. We would also like to thank Leslie DeSimone and Mark Nardi of the U.S. Geological Survey (USGS) for their critical reviews of the report. Appreciation also is extended to the following USGS employees: Kim Otto and Ruth Larkins for editorial reviews, Susan Bergin and Christine Mendelsohn for illustrations, and Ann Marie Squillacci for manuscript preparation and layout.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
