Groundwater Information and Project Support

Project Chief: Michael F. Peck
Cooperator: Georgia Department of Natural Resources Environmental Protection Division, St. Johns River Water Management District, Florida
Year started: 1938

Hydrologic technicians set up a real-time continuous recorder in Glynn County, Georgia, to monitor water-levels and specific conductance. The site is a multipoint well completed in the upper and lower water-bearing zones of the Upper Floridan aquifer. The equipment consists of a data logger, two 30-pounds-per-square-inch transducers to record water levels, an electric pump, and a specific conductance probe. Water levels are measured hourly and specific conductance once-per-day and transmitted by satellite telemetry. Photo by Alan M. Cressler.

Problem

Groundwater supplies about 22 percent of freshwater withdrawals in Georgia—about 1.2 billion gallons per day during 2005. More than 1.9 million people are served by groundwater supplies, and 486 million gallons per day are withdrawn for irrigation (Fanning and Trent, 2009). The distribution and quality of groundwater are highly variable and directly related to geology and natural and human stresses. Monitoring groundwater levels and groundwater quality is essential for the management and development of this resource.

Objectives

• Collect groundwater-level and ground-water-quality data to assess the quantity, quality, and distribution of ground water.
• Provide data to address water-management needs and evaluate the effects of national and local management and conservation programs.
• Contribute data to national databases that will be used to advance the understanding of regional and temporal variations in hydrologic conditions.

Data Requests

The Georgia Groundwater Information and Project Support Unit will, upon request, perform database searches using the Groundwater Site Inventory (GWSI) database.
