- Abstract This map layer contains the shallowest principal aquifers of the conterminous
United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, portrayed as
polygons. The map layer was developed as part of the effort to produce the maps
published at 1:2,500,000 in the printed series "Ground Water Atlas of the United
States". The published maps contain base and cultural features not included in these
data. This is a replacement for the July 1998 map layer called Principal Aquifers of
the 48 Conterminous United States.
- Purpose These data are 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 and analysis, rather than specific local data
analysis.
- Supplemental Information The Ground Water Atlas of the United States (GWA) chapters include additional
information that may be relevant to the use of this map layer, such as maps of
alluvial and glacial aquifers that overlie the aquifers in this map layer, as well
as other information described below. The areal extent of the aquifers, as shown in
this map layer, 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which ground water can be withdrawn, for two reasons: 1) The aquifers shown may have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 map layer
generally represent an interpretation of the surface location (outcrop), or
near-surface location (shallow subcrop) of the uppermost principal 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 map layer. Major alluvial
aquifers that occur along main watercourses are not shown. Significant
unconsolidated sand and gravel aquifers, that are not indicated in this map layer
but are important sources of water, may occur locally in glaciated regions. The user
of this map layer is advised that to get complete information regarding areas that
serve as sources of water, more information about surficial aquifers needs to be
obtained, particularly in glaciated areas. This map layer was constructed by
combining data created for or from the regional GWA chapters. Minor aquifers that
are important local sources of water were mapped in some regions, so the regional
maps in the GWA may show more detail than this map layer. The data were reviewed,
adjusted, and published based on new information provided by national, State, and
local scientists. 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 is not meant to imply a hydrogeologic change coincident with a State boundary.
The aquifer outcrop and shallow subcrop boundaries represent broad, regional
categories and should not be interpreted as site-specific. Comments regarding the
names of aquifers or the hydrogeologic interpretation of the aquifers can be
directed to the U.S. Geological Survey, Water Resources Division, Office of Ground
Water, ogw_webmaster@usgs.gov. This map layer was used as part of the effort to
publish a 1:5,000,000- scale 'Principal Aquifers' map in the National Atlas of the
United States of America series of printed maps. The printed map can be considered a
representation of this map layer with the exceptions of: the smaller scale, slight
differences in the coastline due to generalization, base and cultural information,
and delineation of the glacial-deposit area. These data were developed in
conjunction with the publication of the GWA. For documentation purposes, areas are
referred to by their corresponding GWA chapter letter, or by State. This list shows
the relationship between State names and GWA chapters: >HA 730-B Segment

http://capp.water.usgs.gov/gwa/gwa.html for a graphic depiction of the GWA
chapter regions, as well as more information about the GWA. It may be helpful to
refer to the printed GWA chapters when using the Data, however, there are
significant differences between this national map layer and the printed chapters.
Because the GWA regional chapters were written by different authors, there were
areas of different interpretations and category delineations, aquifer names, etc.,
that became apparent when combining the regions. The following listings show the
differences between aquifer names in the GWA chapters and the aq_name and aq_code
used in this map layer. See the Entity and Attribute Information section for
definitions of the data attributes. >GWA chapter HA 730-B >Name from fig 11,

Related Spatial and Tabular Data Sets A map layer showing the areal extent of sand
and gravel aquifers of alluvial and glacial origin north of the line of Quaternary
continental glaciation is included in the online, interactive National Atlas of the
United States. This map layer ends at the southern limit of glaciation in the United
States; areas north of the limit line contain significant sand and gravel glacial
deposits that are important sources of water for local areas. For additional
information on principal aquifers, please see the Aquifer Basics page at
http://capp.water.usgs.gov/aquiferBasics/index.html. The final data are
being served to the public in the following formats: Spatial Data Transfer Standard
(SDTS), Arc/INFO Export, or ArcView Shapefile.

- Process Description Aquifer outcrop line work for each GWA chapter was compiled on mylar at a
scale of 1:2,000,000, and reduced to 1:2,500,000 for further production work.
For chapters HA 730-G, -H, and -J, the outcrop lines were scribed at a line
width of 0.006 inch. Film positives made from the scribed materials were scanned
on a drum scanner, vectorized, and converted to Arc/INFO coverages. For chapters
HA 730-B, -C, -D, -E, -F, -I, -K, -L, and -M, the aquifer compilation was either
hand digitized, and (or) scanned on a drum scanner, vectorized and converted to
Arc/INFO coverages. The data were then checked, cleaned up, and attribute
creation was done. The Arc/INFO coverages were plotted and checked against the
source compilations. Polygons were attributed using Arcedit. The coverages for
GWA chapters HA 730-B, -C, -D, -E, -F, -I, -K, -L, and -M were used to generate
output files that were imported into Adobe Illustrator for map publication. Each
completed map, at a scale of 1:2,500,000, was reviewed for content and accuracy
by the chapter lead cartographer, Water Resources Discipline Geohydrologic Map
Editor, and chapter author. Individual chapter coverages were appended into one
continuous coverage. Arcedit was used for edgematching and to remove duplicate
labels. No DISSOLVE was done on the coverage; an equivalent of a DISSOLVE was
done manually in Arcedit in conjunction with attribute checking, by removing
arcs that divided adjacent polygons with the same attributes. Several iterations
of editing were performed. These mostly involved ensuring all polygons had
labels and aquifer information and ensuring polygons had correct aquifer
information. No polygons were removed for generalization.

- Process Description Plots of the national aquifers file were made at 1:2,500,000, covering the
areas of the regional GWA chapters. Each plot was compared to the printed GWA
chapter aquifer maps. Where applicable (chapters HA 730-B, -C, -D, -E, -F, -I,
-K, - L, and -M), an Adobe Illustrator file of the coverage data was compared
on-screen with the Illustrator file used to print the published map.
Discrepancies between the coverage file and print file were noted, and the
coverage updated to match the published map. Where a line appeared to shift
noticeably (approximately 1/8 inch at a scale of 1:2,500,000) across the
boundary of two adjacent GWA chapter regions, the line was adjusted for a
smoother appearance. The adjustments may have been made on one or both sides of
the region boundary, depending on a cartographic assessment of the instance.
Coastline Location The 1:2,500,000 principal aquifer maps in the Ground Water
Atlas publications used a coastline and international boundary, derived either
from the map separates from the National Atlas of the United States of America
(published 1970), or from the Digital Line Graph (DLG) data created from the
1970 National Atlas. GWA chapters HA 730-G, -J, and -H used coastline and
boundary filmwork photo-mechanically reduced from the 1:2,000,000 National Atlas
map separates. The remaining chapters used coastline and boundary data from the
DLG's. A revision of the DLG data took place in 1997, after the creation of the
chapter aquifer map data. After the edgematching, a decision was made to replace
the coast and international boundary of this national-level aquifer data with
one derived from a newer version of 1997 DLG data. State boundary data from the
National Atlas was used to provide the coastline and two aquifer boundaries that
coincide with State lines. The existing outline (coastline and international
boundary line) was removed, the new outline added to the coverage, and the
remaining aquifer contact lines snapped to the new outline. The coverage was
re-cleaned, data categories checked onscreen and with plots, and corrected. Line
and labeling corrections, such as undershoots, overshoots, and improper labels
were corrected in Arcedit. There are some slight locational differences between
this map layer and the printed GWA chapters. For example, there are several
small differences in the number of small islands in coastal areas and the
categorization of these small islands was assigned to either the nearby
principal aquifer category or as Not a principal aquifer, depending on the
location and categorization of similar small islands in the printed GWA
chapters. There are other differences in the categorization of some
land/shoreline-related features. For example, an area symbolized as a bay in a
GWA chapter may be land in this map layer. Western Montana During the review of
a printed map made from this national-level aquifer data, the compiler, James A.
Miller, requested a change in the representation of aquifers in western Montana.
The area affected is in the following counties: Lincoln, Flathead, Sanders,
Lake, Mineral, Missoula, Powell, Ravalli, Granite, Lewis and Clark, Deer Lodge,
Silver Bow, Jefferson, Broadwater, Gallatin, Beavershead, and Madison. These
areas fall under the Northern Rocky Mountain Intermontane Basins Regional
Aquifer Systems Analysis (RASA). With one exception, the aquifers, as shown in
GWA chapter I, figure 7 in the listed counties were removed and replaced with
unconsolidated-deposit areas as shown in GWA chapter HA 730-I, figure 6. The
exception is an area in northern Flathead county, listed as an Upper Tertiary
aquifer in GWA chapter I, figure 7, that was retained as an area but
reclassified as a Lower Tertiary aquifer.

Islands. Where polygons ended at the shoreline, National Atlas State boundaries
were used. The final Illustrator file was exported into a DXF file. The DXF file
was converted to a coverage. Using the TRANSFORM command, the coverage
containing the aquifer lines was rubber-sheeted to the coverage containing
registration tics, and was then projected from geographic coordinates to Albers
Equal-Area Conic projection for verification purposes. The aquifer coverage was
cleaned, the topology was built, and labels were added. Attributes were added as

- Process Description The Principal Aquifers map published in 1998 was reviewed and modified,
resulting in 57 aquifers, 36 of which were the same geographically as in the
1998 publication. Aquifers were aggregated, divided, renamed and updated from
more recent publications, using a variety of techniques, which include scanning,
importing unpublished digital data and paper compilation at 1:2,500,000 scale.
The updated Adobe Illustrator aquifer data was exported into a DXF file. The DXF
file was converted to a coverage. Using the TRANSFORM command, the coverage
