Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set describes ground-water regions in the United States defined by the U.S. Geological Survey. These ground-water regions are useful for dividing the United States into areas of roughly similar hydrologic characterstics and water-use patterns. These regions are very generalized and were developed from a illustration published at a scale of approximately 1:20 million.

Purpose

This data set is a generalized representation of ground-water areas in the United States and was created for use in the analysis of ground-water quality data on volatile organic compounds (VOCs) by the U.S. Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) VOC National Synthesis Team. Polygons from this data set were used with common ranges of hydraulic characteristics provided in the Entity_and_Attribute_Overview below to relate ground-water resources with NAWQA study areas on a broad scale.
