Delineation and description of the regional aquifer systems of Tennessee; Cumberland Plateau aquifer system
J. V. Brahana, J. A. Macy, Dolores Mulderink, Dawn Zemo
1986, Open-File Report 82-338
The Cumberland Plateau aquifer system consists of Pennsylvanian sandstones, conglomerates, shales, and coals which underlie the Cumberland Plateau in Tennessee. Major water-bearing zones occur within the sandstones and conglomerates in interconnected fractures. The water-bearing formations are separated by shale and siltstone that retard the vertical circulation of ground water, The...
