Frick, E.A., M.B. Gregory, D.L. Calhoun and E.H. Hopkins. 2002. Water Quality and Aquatic Communities of Upland Wetlands, Cumberland Island National Seashore, Georgia, April 1999 to July 2000. U.S. Geological Survey, Water Resources Investigations Report 02-4082.

This report summarizes the results of several studies conducted on Cumberland Island, Georgia investigating groundwater, surface water and ecological features in 1999 and 2000.


Gill, H.E. and G.D. Mitchell. 1979. Results of Colonels Island Deep Hydrologic test well, Appendix C of Georgia Geologic Survey, Investigations of Alternative Sources of Ground Water in the Coastal Area of Georgia: Georgia Department of Natural Resources, Open File Report 80-3, p. C1-C13.

A test well was located on Colonels Island, Georgia to gather data about vertical groundwater flow patterns and quality. Increased pumpage of the principal artesian aquifer allows vertical migration of saltwater.


Gregg, D.O. 1966. An Analysis of ground-water fluctuations caused by ocean tides in Glynn County, Georgia. Groundwater, 4:24-32.

Tidal effect on artesian water wells was evaluated for several wells at different distances from tidal bodies of water. A formula was derived from this data to rapidly calculate tidal efficiency.


Harris, William H.,. 1967. Stratification of Fresh and Salt Water on Barrier Islands as a Result of Differences in Sediment Permeability. Water Resources Research, 3:89-97.

The interface between fresh and salt water beneath Hatteras Island, North Carolina was investigated in terms of the permeability of sediments at depth. Permeable sediments were found to contain less chloride than non-permeable sediments.


Herndon, J.G. 1991. The Hydrogeology of Southern Cumberland Island, Georgia. Masters thesis. Georgia State University, Atlanta, GA 183 p.

In order to determine how channel dredging may affect groundwater in the Pliocene- Miocene aquifer, 10 wells were installed at different cluster sites on Cumberland Island, Georgia. Data was collected from the Miocene sand aquifer, the Pliocene-Miocene
