Evaluation of the Downward Migration of Saltwater to the Upper Floridan Aquifer in the Savannah, Georgia, and Hilton Head Island, South Carolina, Area
(Georgia Institute of Technology, 2007-03)The Upper Floridan aquifer underlies all of Florida, most of the Georgia and Alabama Coastal Plain, and large parts of coastal South Carolina. The aquifer is composed primarily of carbonate rock of varying permeability ... -
Optimization of Ground-Water Pumpage Distribution to Limit Chloride Plume Expansion in the Upper Floridan Aquifer near Brunswick, Georgia
(Georgia Institute of Technology, 2007-03)Since the late 1950s, and until recently, the salinity of ground water in the Upper Floridan aquifer near downtown Brunswick, Georgia, has increased, with chloride concentrations exceeding 250 milligrams per liter in an ... -
Analysis of Tracer Migration in a Diverging Radial Flow Field
(Georgia Institute of Technology, 2007-03)Hydrodynamic dispersion is an important factor controlling contaminant migration in the subsurface environment. However, few comprehensive data sets exist for critically evaluating the impact of travel distance and site ... -
Hydraulic Gradients in Recharge and Discharge Areas and Apparent Ground-Water Age Dates from the Characterization of Multiple Regolith-Fractured Bedrock Ground-Water Research Stations in North Carolina
(Georgia Institute of Technology, 2007-03)As part of the North Carolina Piedmont and Mountains Resource Evaluation Program, research stations were established in representative, regional geologic belts to study ground-water flow and quality. Two major findings ... -
Hydrologic Behavior of Gullies in the South Carolina Piedmont
(Georgia Institute of Technology, 2007-03)The Piedmont region in the United States has been eroded and gullied due to deforestation and cultivation during the 1700 and 1800. Currently, a majority of these gullies are under forest vegetation and appear stable; ... -
An Improved Technique for Soil Solution Sampling in the Vadose Zone Utilizing Real-Time Data
(Georgia Institute of Technology, 2007-03)The vadose zone is an area of ongoing concern because of its role in the fate and transport of chemicals resulting from waste disposal and agricultural practices. The degree of contamination and movement of solutes in soil ... -
Chlor-Alkali Plant Contributes to Mercury Contamination in the Savannah River
(Georgia Institute of Technology, 2007-03)For many years the Savannah River has suffered fish consumption warnings. While several potential sources of mercury may contribute to this contamination, the chlor-alkali facility in Augusta, which produces chlorine by ... -
Preliminary Data from a Comprehensive Savannah River Study: The First 6 Months
(Georgia Institute of Technology, 2007-03)Southeastern Natural Sciences Academy has initiated a two year comprehensive study to assess the upstream impacts on water quality in the Savannah River with emphasis on the Augusta urban corridor. One of the driving forces ... -
First, Do No Harm
(Georgia Institute of Technology, 2007-03)There is an emerging awareness of the importance of sustainability and an integrated cross-cutting approach to environmental policy development. These trends along with technical and scientific developments underpin a ... -
Distribution of Recharging and Vulnerability of the Tertiary Limestone Aquifer, South Carolina: Regional Gradients and Important Outliers
(Georgia Institute of Technology, 2007-03)The distribution of ground-water radiocarbon ages from the Tertiary limestone aquifer (includes the Floridan aquifer) in South Carolina shows both a typical trend for a regional sedimentary aquifer plus a less commonly ... -
Coastal Watershed Condition Assessment of Fort Pulaski National Monument
(Georgia Institute of Technology, 2007-03)We recently completed an assessment of Fort Pulaski National Monument for the Water Resources Division of the National Park Service. The report provides information on park resources, water quality and impairments, and ... -
Saltwater Contamination in the Upper Floridan Aquifer in the Savannah/Vernonburg, Georgia, Area, 2004–2006
(Georgia Institute of Technology, 2007-03)Since January 2004, and possibly as early as 2001, naturally-occurring saltwater has contaminated wells in the Savannah/Vernonburg, Georgia, area (Fig. 1, Hall and Carter, 2004; Hall and Peck, 2005). During April 2004, the ... -
Effects of Pumpage Reductions in the Savannah, Georgia–Hilton Head Island, South Carolina, Area on Saltwater Intrusion near Hilton Head Island
(Georgia Institute of Technology, 2007-03)Numerical simulations were used to test the effects of variable pumpage reductions on the movement of chloride plumes in the Upper Floridan aquifer at the northern end of Hilton Head Island, at Pinckney Island, and near ... -
Predicting Freshwater and Oligohaline Tidal Marsh Vegetation Communities in the Vicinity of the Savannah National Wildlife Refuge
(Georgia Institute of Technology, 2007-03)A large portion of the remaining tidal freshwater marshes left in the southeastern U.S. lies within the braided channels of the lower Savannah River deltaic marsh complex (Georgia, USA). These marshes occur upstream from ... -
Simulation of Salinity in the Tidal Marshes in the Vicinity of the Savannah National Wildlife Refuge Using Artificial Neural Networks
(Georgia Institute of Technology, 2007-03)The Savannah Harbor is one of the busiest ports on the East Coast of the United States and is located downstream from the Savannah National Wildlife Refuge, which is one of the Nation’s largest freshwater tidal marshes. ... -
Longitudinal Dispersion and Tracer Migration in a Radial Flow Field
(Georgia Institute of Technology, 2007-03)Hydrodynamic dispersion is an important factor controlling contaminant migration in the subsurface environment. However, few comprehensive data sets exist for evaluating the impact of travel distance and site heterogeneity ... -
Current Conditions of Historical Mussel Habitat in the Flint River Basin, Georgia
(Georgia Institute of Technology, 2007-03)Streams of the Flint River Basin (FRB) remain as viable habitat for many freshwater species and harbor some of the most diverse mussel assemblages in the Southeast. However, land use changes, hydrologic alterations, and ... -
