Assessment of Surficial and Brunswick Aquifer Systems, Coastal Georgia
The Upper Floridan aquifer is the primary source of water in the coastal area of Georgia. Declining water levels and localized occurrences of saltwater contamination in the Upper Floridan aquifer have resulted in the Georgia Environmental Protection Division capping permitted withdrawals at 1997 rates from the Upper Floridan aquifer in parts of the coastal area. These restrictions have prompted interest in developing supplemental sources of ground water, including the surficial and Brunswick aquifer systems. The surficial aquifer system includes the water table and semiconfined zones; the Brunswick aquifer system includes the upper and lower Brunswick aquifers (Clarke, 2003).
Objectives

- Characterize the geologic and water-bearing properties of the surficial and Brunswick aquifer systems.
- Characterize the water quality of the surficial and Brunswick aquifer systems.
- Develop monitoring network for management of the surficial and Brunswick aquifer systems.
Progress and Significant Results, 2002 - 2003
- Old Sunbury Road site, Liberty County. Completed six test wells, conducted a 24-hour aquifer test in the semiconfined zone of the surficial aquifer and a 48-hour aquifer test in the lower Brunswick aquifer.
- City of Ludowici Prison site, Long County. Completed two test wells and completed 24-hour aquifer tests in wells completed in the semiconfined zone of the surficial aquifer and in the upper and lower Brunswick aquifers, combined.
- Waverly Fire Station No. 17 site, Camden County.
- Completed three test wells and completed 24-hour aquifer tests in wells completed in the semiconfined zone of the surficial aquifer and the upper Brunswick aquifer.
- Lawrence Road Fire Station site, St. Simons, Glynn County. Completed wells in the semiconfined zone of the surficial aquifer and in the lower Brunswick aquifer.
- Darien site, McIntosh County. Completed test wells in the surficial aquifer, semiconfined zone of the surficial aquifer, and lower Brunswick aquifer.
