Abstract

A map shows generalized contours of the altitude of water levels for wells completed in the Sparta-Memphis aquifer in eastern Arkansas. Most water-level measurements used in constructing the map were from the spring of 1980, but supplemental measurements from other years indicated no long-term change in water levels. Hydrographs for selected wells are included to show trends and lack of trends in water-level changes. The aquifer in the Sparta Sand and Memphis Sand of Eocene age which consists of fine to medium sand interbedded with salt, clay, and lignite. The aquifer supplies much of the water used for industry and public supply for eastern Arkansas. Some irrigation users also obtain supplies from the aquifer. Cones of depression caused by pumpage for industrial and public supplies occur near Camden, El Dorado, Magnolia, Pine Buff, and West Memphis. (USGS)
