Ground-water recharge potential maps show land areas characterized by their abilities to transmit water from land surface to a depth of 20 feet. The basic methods for mapping ground-water recharge potential are presented in Delaware Geological Survey Open File Report No. 34 (Andres, 1991) and were developed specifically for the geohydrologic conditions present in the Coastal Plain of Delaware. The digital data for this layer comes from DGS Digital Data Product DP 02-01, Digital Ground-Water Recharge Potential Map Data For Kent and Sussex Counties, Delaware: A. S. Andres, C. S. Howard, T. A. Keyser, L. T. Wang, 2002.
Please Note: Many datasets on this site are available as compressed and zipped 7z files. To "unzip" the 7z file, you must obtain the free and open source 7zip program.

The GIS data are distributed in the North American Datum of 1983, Universal Transverse Mercator Zone 18-North map projection, in meters. The GIS data are in ESRI, Inc., interchange format (E00) and can be imported into ArcView or ArcMap as coverages, as well as in standard shapefile format. The attribute "recharge" contains the recharge potential rating. Users should consult their user guide for instructions on how to import the data. A metadata file in xml format is also included.
