U.S. GEOLOGICAL SURVEY
Water-Data Report MD-DE-DC-00-2
Water resources data for the 2000 water year for Maryland and Delaware consist of records of water levels and water quality of ground-water wells. This report (Volume 2. Ground-Water Data) contains water levels at 347 observation wells, discharge records for 5 springs, and water quality at 225 wells, 13 piezometers, and 4 springs. Locations of ground-water level wells are shown on figures 5 and 6. Locations of ground-water-quality sites are shown on figure 7. The data in this report represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State, local, and Federal agencies in Maryland and Delaware.
