Abstract
A water-level map of the Sparta and Memphis aquifers for 1993 is presented in this map report. The Sparta-Memphis aquifer, consisting of sands of Eocene age, is present in much of southern and eastern Arkansas. The potentiometric surface map and long-term hydrographs illustrate the effects of large withdrawals for industrial and public supply and, to a lesser extent, agricultural use, on water levels in the aquifer. Three cones of depression, centered in Columbia, Jefferson, and Union Counties, occur in the potentiometric surface.
