Groundwater Monitoring Program for the Brunswick-Glynn County Area, Georgia

Project Chief: Gregory S. Cherry
Cooperator: Brunswick-Glynn County Joint Water & Sewer Commission
Year started: 1959

Problem

Brunswick, Georgia, showing bridge and boats at dock.In the Brunswick area, saltwater has contaminated the Upper Floridan aquifer for nearly 50 years. Currently within an area of several square miles in downtown Brunswick, the aquifer yields water with a chloride concentration greater than 2,000 milligrams per liter (mg/L), above the State and Federal secondary drinking-water standard of 250 mg/L (Georgia Environmental Protection Division, 1997; U.S. Environmental Protection Agency, 2000). Saltwater contamination has constrained further development of the Upper Floridan aquifer in the Brunswick area, which has stimulated interest in the development of alternative sources of water supply, primarily from the shallower surficial and Brunswick aquifer systems.

View chloride-conentration maps, 2010 and 2011, along with the changes over that time period.

Objectives

  • Define mechanisms of ground-water flow and movement of saltwater in the Floridan aquifer system.
  • Define the vertical geometry of the high-chloride plume.
  • Assess alternative sources of water supply from the surficial and Brunswick aquifer systems and the Lower Floridan aquifer.
  • Monitor long-term groundwater levels and quality; develop and maintain a comprehensive groundwater database.
