Ator, Judith M. Denver, David E. Krantz, Wayne L. Newell, and Sarah K. Martucci 2005 A Surficial Hydrogeologic Framework for the Mid-Atlantic Coastal Plain U.S. Geological Survey Professional Paper pp1680 Reston, VA U.S. Geological Survey http://pubs.er.usgs.gov/publication/pp1680 The hydrogeologic framework was developed from a combination of the physiography and the predominant texture of surficial geologic units in the Mid-Atlantic Coastal Plain. It describes the primary natural physical factors that affect the flow and chemistry of shallow ground water and small streams in the Mid-Atlantic Coastal Plain. Seven hydrogeologic subregions were defined. Some of the subregions correspond directly to the physiographic subprovinces of the region; others were generalized within subprovinces based on sediment texture. For more information, see U. S. Geological Survey Professional Paper 1680. This data set was developed as a tool for understanding regional water-quality patterns as they relate to hydrogeologic conditions in the Mid-Atlantic Coastal Plain.

The surficial geology coverage was dissolved on item LITH and intersected with the physiography coverage. The resulting coverage was plotted at 1:1,000,000 scale and the seven relatively contiguous subregions were outlined by hand on the basis of physiography and sediment lithology. The arcs corresponding to these subregion boundaries were copied from the intersected coverage to a new coverage; a few boundaries were also copied from the subcropping geology coverage or digitized on-screen. Polygon topology and attributes were added to this new coverage to create the hydrogeologic framework coverage. The hydrogeologic framework coverage includes seven distinct subregions identified by the items, FCODE (an integer from 1 to 7) and NAME. 1998 First draft of metadata created by skkelley using FGDCMETA.AML ver. 1.31 10/16/98 on ArcInfo data set framewrk 19990927 Metadata edited by M.R.
