Abstract

A brief study of the Atlantic Coastal Plain aquifers in the vicinity of the Washington, D.C., metropolitan area was made, using available data, to estimate the water-supply potential of these aquifers and to determine the possibility of developing an emergency water supply during droughts. Assuming that the data available are representative, the study indicates that the water-supply potential of these aquifers, within an assumed 30-mile radius of Washington, D.C., is about 170 million gallons per day. That is, these aquifers, which are now furnishing an estimated 60 million gallons per day, could be developed to supply an additional 110 million gallons per day on a continuous basis. This quantity might be even larger if a significant amount of water is derived from leakage through finer grained confining beds, but further studies would be necessary to determine the amount of leakage and the long-term effects of large-scale continuous use. Furthermore, under intermittent pumping conditions, an assumed emergency supply of 100 million gallons per day could probably be developed from well fields within a 30-mile radius of Washington. An exploration and testing program would be necessary to assess the reliability of these preliminary estimates.
