Abstract
This data set contains the shallowest principal aquifers of New York State, portrayed as lines. The data set 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 data set was previously called Principal Aquifers of the 48 Contiguous 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 data set, such as maps of alluvial and glacial aquifers that overlie the aquifers in this data set, as well as other information described below. 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 These aquifer areas are not necessarily the only areas in which ground water can be withdrawn, for two reasons: 1) The aquifers shown may have a larger areal extent than is represented here.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 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 data set. Major alluvial aquifers that occur along main watercourses are not shown. Significant unconsolidated sand and gravel aquifers, that are not indicated in this data set but are important sources of water, may occur locally in glaciated regions. The user of this data set 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 data set 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 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 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, Roy Sonenshein, sunshine@usgs.gov, (305) 717-5824. This data set 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 data set 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-L Segment 11-Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, West Virginia HA 730-M Segment 12-Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, Vermont Refer to 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. Although these spatial data can stand alone, it may be helpful to refer to the printed GWA chapters when using the data. There are three subject areas in which there are significant differences between this data set and the printed chapters: category changes, which are described below; coastline location, and the representation of aquifers in Western Montana, both of which are discussed in the Process Description under Lineage. Category Changes 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. In most cases, the name and delineation of the aquifer is identical between this data set and the GWA printed maps, but there are several areas of differences. In some cases, a single aquifer from a GWA chapter is represented among multiple aquifers in this data set. The following listings show the differences between aquifer names in the GWA chapters and the aq_name and aq_code used in this data set. See the Entity and Attribute Information section for definitions of the data attributes.

This data set shows the southern limit of glaciation in the United States; areas north of the limit line may contain significant sand and gravel glacial deposits that are important sources of water for local areas. The final data are being served to the public in the following formats: Arc/INFO Export, or ArcView Shapefile. Other Online Sources of Information About Aquifers include Aquifer Basics https://water.usgs.gov/ogw/aquiferbasics/index.html provides information about the various aquifer types; The USGS Office of Ground Water provides information about the ground-water resources of the Nation and ground-water activities of the USGS http://water.usgs.gov/ogw/; The Ground Water Atlas of the United States http://capp.water.usgs.gov/gwa/index.htmldescribes the location, the extent, and the geologic and hydrologic characteristics of the important aquifers of the Nation.
