Abstract

This report presents a map showing the change in the potentiometric surface of the Magothy aquifer in the Magothy Formation of Cretaceous age in Southern Maryland for September 1975 and September 1999. The map, based on water level measurements in 61 wells, shows that the potentiometric surface during the 24-year period ranged from zero at the outcrop area, which is in the northernmost part of the study area, to a decline of 76 feet in Waldorf. Waldorf is located near the southwesternmost part of the study area, and approaches the downdip boundary of the aquifer.
