  Description:
    Abstract: This data set represents the extent of the Arkansas Stream-valley alluvial aquifer in the state of Arkansas.  This vector data set delineates an image file of an alluvial aquifer as converted to a GIS shape file. It was developed as part of the USGS's National Water Quality Assessment program. The image file originated in the 'Ground Water Atlas of the United States' (U.S. Geological Survey HA 730-F).  The scale of the source material is 1:2,500,000 and thus the data are not intended for use at a larger scale.
    Purpose: This shape file makes available GIS data of the alluvial aquifers of the United States.  It was created in conjunction with a study that produced Scientific Investigations Report 2008-5003, 'Estimated Withdrawals from Stream-Valley Aquifers and Refined Estimated Withdrawals from Selected Aquifers in the United States, 2000.'  It is intended for use in publications, at a scale of 1:2,500,000 or smaller.  Due to the small scale, the primary intended use is for regional and national data display rather than specific local data analysis.
    Supplemental_Information:
      The Ground Water Atlas of the United States chapters includes additional information that may be relevant to the use of this data set.  The areal extent of the aquifers, as shown in this data set, represents the area in which a named aquifer is the shallowest of the principal aquifers.  These aquifer areas are not necessarily the only areas in which ground water can be withdrawn, for two reasons: (1) the aquifers shown may have a larger areal extent than is represented here.  The boundaries in this data set generally represent an interpretation of the surface location (outcrop), or near-surface location (shallow subcrop) of the uppermost aquifer for the area.  An aquifer may extend beyond the area shown, but be overlain by one or more other aquifers, and (or) low-permeability material. (2) There may be areas of water-bearing surficial material not shown in this data set.  

      The juxtaposition of regionally mapped aquifers has led to some instances where an aquifer outcrop or shallow subcrop is bounded by a State line.  This is a result of the regional mapping and national categorization methods used and are not meant to imply a hydrogeologic change coincident with a State boundary.

      Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

      Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ARC/INFO format, this metadata file may include some ARC/INFO-specific terminology.
