The Difference Between the Potentiometric Surfaces of the Magothy Aquifer, September 1975 and September 2001 in Southern Maryland

Curtin, Stephen E.; Andreasen, David C.; Wheeler, Judith C.

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 2001. The map, based on water level measurements in 54 wells, shows that during the 26-year period, the potentiometric surface ranged from zero at the outcrop area, which is in the northernmost part of the study area, to a decline of 75 feet at Waldorf. Waldorf is located near the southwesternmost part of the study area, and approaches the downdip boundary of the aquifer.
