Water Quality

USGS scientists predicted stream biological conditions across the Chesapeake Bay watershed from 1985 through 2023, revealing widespread changes but only a ~1% increase in stream length classified as improved. These predicted improvements fell short of the Chesapeake Bay Program’s goal of improving the health of 10% of streams by 2025.

The Research Triangle area, located within the upper Cape Fear and Neuse River basins, is one of the most rapidly developing areas in the Nation. Growth has increased demand for water from public suppliers, the majority of which draw water from streams and lakes in the region. Growth also brings the threat of greater loads of contaminants and new contaminant sources that, if not properly managed...

The North Carolina Department of Transportation (NCDOT) has partnered with the U.S. Geological Survey (USGS) to assess water-quality impacts resulting from the I-26 construction projects in western North Carolina. Streamflow, precipitation, and water-quality monitoring data will support the NCDOT construction-site inspections by allowing adaptive responses to potential construction impacts and...

Background: How safe is it to swim, wade, and boat in the Chattahoochee River today? For a highly urbanized river such as the Chattahoochee, much of the answer depends on bacteria levels in the water. This website provides "real time" turbidity data, the estimated Escherichia coli (E coli) bacteria count, the most recent E. coli bacteria counts (sample collected each Thursday), and National Park...

This ongoing USGS study for Georgia, South Carolina, and North Carolina aims to (1) compute low-flow statistics at selected continuous-record streamgages in Georgia, South Carolina, and North Carolina and to (2) develop regional regression equations for a subset of those low-flow characteristics for streams that are not substantially affected by tides, regulation, diversions, or other...

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 working...

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 framework and...

In the Atlanta metropolitan area, a hydrologic data-collection network has been established to collect real-time streamflow, precipitation, continuous and discrete water-quality data. The USGS South Atlantic Water Science Center (SAWSC) Urban Hydrology Unit (UHU), located in Norcross, Georgia, has been working in cooperation with local municipal and county agencies in and around the Atlanta...

In 2002, The Nature Conservancy and the U.S. Army Corps of Engineers launched a collaborative effort to find more sustainable ways to manage river infrastructure to maximize benefits for people and nature. As of 2021, the Sustainable Rivers Program study area includes 40 rivers, 89 reservoirs, and 10,953 downstream river miles. The USGS South Atlantic Water Science Center and USGS Wetland and...

Fort Gordon is a U.S. Department of the Army facility located in east-central Georgia, approximately 10 miles west of Augusta, Georgia). The U.S. Geological Survey (USGS) South Atlantic Water Science Center is working cooperatively with the U.S. Department of the Army Environmental and Natural Resources Management Office of the U.S. Army Signal Center and Fort Gordon to assess the quality of...

The objective of this project is to develop a groundwater-flow model that can be used by Aiken County water managers to manage current and projected reported and unreported demands on groundwater resource and to ensure the highest quality of groundwater. Project Chief: Bruce Campbell Cooperator: Aiken County, Gilbert-Summit Rural Water District, City of Aiken, Breezy Hill Water and Sewer and...

A pilot-scale phytoremediation system is being implemented to address shallow groundwater contaminated by residual pesticides from a landfill near West Columbia, South Carolina. The pilot-scale phytoremediation system will test the idea that fast growing hybrid poplar trees will take up shallow groundwater that contains organochlorine pesticides, such as β-BHC compounds and toxaphene, at higher...
