Abstract

This report presents a map showing the potentiometric surface of the Upper Patapsco aquifer in the Patapsco Formation of Cretaceous age in Southern Maryland during September 1999. The map is based on water-level measurements in 49 wells. The potentiometric surface was 119 feet above sea level near the northern boundary and outcrop area of the aquifer in a topographically high area of Anne Arundel County, and 55 feet above sea level in a similar setting in Prince Georges County. From these high areas, the potentiometric surface declined to the southeast toward large well fields in the Annapolis area, and from all directions toward a cone of depression southwest of Waldorf. Ground-water levels declined to 20 feet below sea level in the Annapolis area, and 131 feet below sea level southwest of Waldorf.
