Abstract
This report presents a map that shows the change in the potentiometric surface of the Aquia aquifer in the Aquia Formation of Paleocene age in Southern Maryland for September 1982 and September 1997. The map, based on water-level measurements in 68 wells, shows that the change of the potentiometric surface during the 15-year period ranged from a rise of 2 feet in the most northern part of the study area, which is the outcrop of the aquifer, to a decline of 95 feet at Lexington Park. Lexinton Park is near the most southeastern part of the study area and approaches the downdip boundary of the aquifer.
