Water resources data Maryland and Delaware, water year 1993, Volume 2: Ground-water data

Abstract

This series of annual reports for Maryland and Delaware began with the 1961 water year with a report that contained only data relating to the quantities of surface water. For the 1964 water year, a similar report was introduced that contained only data relating to water quality. Beginning with the 1975 water year, the report format was changed to present, in one volume, data on quantities of surface water, quality of surface and ground water, and ground-water levels.In the 1989 water year, the report format was changed to two volumes. Both volumes contained data on quantities of surface water, quality of surface end ground water, and ground-water levels. Volume 1 contained data on the Atlantic Slope Basins (Delaware River thru Patuxent River) and Volume 2 contained data on the Monongahela and Potomac River basins. Beginning with the 1991 water year, Volume 1 contains all information on quantities of surface water and surfacewater-quality data and Volume 2 contains ground-water levels and ground-water-quality data. This report is Volume 2 in our 1993 series and includes records of water levels and water quality of ground-water wells and springs. It contains records for water levels at 365 observation wells, discharge data for 5 springs, and water quality at 151 wells. Location of ground-water level wells are shown on figures 3 and 4. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Maryland and Delaware.
