Background Information |
Sample Map
An aquifer is a geologic formation, group of formations, or part of a formation that contains sufficient saturated, permeable material to yield significant quantities of water to wells and springs. The U.S. Geological Survey (USGS) Water Resources Program collects information on aquifers and other water resources to determine the quantity and quality of the Nation's water supplies. This information is used by Federal, State, and local agencies for water-resources planning and management.
Alluvial aquifers are those that were deposited by a stream or other body of running water in a streambed, on a flood plain, on a delta, or at the base of a mountain. Glacial aquifers are formations that were deposited by a glacier. This map layer was compiled by the USGS.
The Aquifers of Alluvial and Glacial Origin map layer shows unconsolidated
sand and gravel aquifers of alluvial and glacial origin north of the
southernmost line of glaciation. These aquifers are found in the States
of Maine, Vermont, New Hampshire, Connecticut, Massachusetts, Rhode
Island, New Jersey, New York, Pennsylvania, Ohio, Indiana, Michigan,
Wisconsin, Illinois, Minnesota, Iowa, Missouri, Kansas, Nebraska,
South Dakota, North Dakota, and Montana. Additional aquifer information
is included in the National Atlas Principal
Aquifers of the 48 Conterminous United States map layer. Information
on aquifer types can be found on the Aquifer
Basics page, and further water science information is available
from the USGS
Ground Water Information Pages, from the USGS
Learning Web Explorers Water page, and from the Ground
Water Atlas of the United States. |
