Development of a Coastal Salinity Index

A critical aspect of the uniqueness of coastal drought is the effects on the salinity dynamics of creeks, rivers, and estuaries. The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response...

North Carolina Shale Gas Baseline Groundwater Sampling Project

The U.S. Geological Survey (USGS) South Atlantic Water Science Center is conducted an inventory of well records and baseline groundwater-quality sampling to better delineate areas of groundwater use and groundwater-quality characteristics prior to potential shale gas exploration in the Triassic Basins of Lee and Chatham Counties, North Carolina. The compilation of baseline groundwater-quality...

Groundwater Monitoring Program for the Augusta–Richmond County Area, GA

Water supply in the Augusta–Richmond County, GA area is provided in part by three well fields that withdraw water from the Dublin–Midville aquifer system. 

The U.S. Geological Survey operates a groundwater and water-quality monitoring program to support water-management decisions and provide a basis for future groundwater modeling efforts while adding to regional characterization of...

Characterization of subsurface bedrock fractures at GMH Electronics EPA Superfund Site near Roxboro, NC

The US Environmental Protection designated a former electronics manufacturing facility as a Superfund cleanup site near Roxboro, North Carolina. Operations at a former gasoline station/store and electronic component production facility may have resulted in the presence of a volatile-organic compound (VOC) plume in groundwater in the area; referred to as the "GMH Electronics Site".

Effects of Land-Applied Biosolids on Water Quality in the Jordan Lake Watershed, North Carolina

Land application of municipal wastewater biosolids is the most common method of biosolids management used in North Carolina and the United States. Biosolids have characteristics that may be beneficial to soil and plants. Land application can take advantage of these beneficial qualities, whereas disposal in landfills or incineration poses no beneficial use of the waste.

However, recent...

Brunswick County, NC Groundwater-Level Monitoring

Since 2000, the population of Brunswick County has grown by more than 50%. A growth of this magnitude places significant stress on Brunswick County’s natural resources. County planners have recognized the potential consequences of land use changes associated with growth and the resulting increased demand on water resources by consolidating the many public utility providers into one...

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

In the Brunswick, Georgia area, saltwater has contaminated the Upper Floridan aquifer for nearly 50 years. 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.

USGS is...

Geohydrology and Effects of Climate and Pumpage Change on Water Resources of the Aucilla–Suwannee–Ochlockonee River Basin, South-Central Georgia and Adjacent Areas of Florida, Progress and Significant Results, 2006—2007

Episodic droughts and increased pumpage since the mid-1970s have caused unprecedented ground-water level decline in the Upper Floridan aquifer in much of the roughly 8,000 square-mile Aucilla-Suwannee-Ochlockonee (ASO) River Basin.

To address concerns about water availability, USGS worked with Georgia Environmental Protection Division to improve understanding of the hydrogeologic...

Phytoremediation of PAH-Contaminated Groundwater: Contaminant Remediation and Hydrologic Control

A priority issue for the USGS is to contribute to understanding the processes associated with waste isolation and remediation of contaminated environments. This a research involves developing new methods for acquiring water resources information, including methods of data collection and analysis, and producing new understanding that describes or explains processes important to water-related...

Simulation of Groundwater Flow in the Charleston Aquifer near Mount Pleasant, SC – an Update

The objective of the investigation is to use an existing, updated groundwater-flow model of the South Carolina Coastal Plain aquifers and confining units in the Mount Pleasant area created by Petkewich and Campbell to simulate current groundwater conditions and to include current planning goals developed by the Mount Pleasant Waterworks. The scope of the groundwater simulations will include...
