Albemarle-Pamlico Drainage Study Unit
The Albemarle-Pamilco Drainage Study Unit (ALBE) is part of the National Water Quality Program (NWQP, formerly National Water Quality Assessment (NAWQA)). NWQP is an ongoing program of the U.S. Geological Survey to provide an understanding of water-quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions.
Surface-Water Quality in Agricultural Watersheds of the North Carolina Coastal Plain Associated with Concentrated Animal Feeding Operations
The effects of concentrated animal feeding operations (CAFOs) on water quality were investigated at 54 agricultural stream sites throughout the North Carolina Coastal Plain during 2012 and 2013. Three general watershed land-use types were examined during the study, including 18 background watersheds with no active CAFOs, 18 watersheds with one or more active swine CAFOs but no poultry CAFOs, and...
Factors Affecting Nitrogen and Phosphorus Loads in Nutrient-Sensitive Water of Eastern North Carolina
Data collected between 1997 and 2008 at 48 stream sites were used to characterize relations between watershed settings and stream nutrient yields throughout central and eastern North Carolina. The focus of the investigation was to identify environmental variables in watersheds that influence nutrient export for supporting the development and prioritization of management strategies for restoring...
Datasets for Assessment of Nutrient Load Estimation Approaches for Small Urban Streams in Durham, North Carolina, 2009-2020
In cooperation with the City of Durham Public Works Department Stormwater Division, the U.S. Geological Survey (USGS) conducted a study to evaluate whether alternate monitoring strategies that incorporated samples collected across an increased range of streamflows would improve nutrient load estimates for Ellerbe and Sandy Creeks, two small, highly urbanized streams in the City of Durham, North Ca
Datasets for Characterization of Water-Quality and Bed-Sediment Conditions in Currituck Sound, North Carolina, 2011-18
The U.S. Geological Survey, in cooperation with the North Carolina Turnpike Authority, conducted a study to establish baseline water-quality conditions and bed-sediment chemistry in Currituck Sound, North Carolina, prior to construction of the Mid-Currituck Bridge.

Characterization of water-quality and bed-sediment conditions in Currituck Sound, North Carolina, prior to the Mid-Currituck Bridge construction, 2011–18
The North Carolina Turnpike Authority plans to improve transportation in the Currituck Sound area by constructing a two-lane bridge—the Mid-Currituck Bridge—across Currituck Sound from the mainland to the Outer Banks, North Carolina. The results of the final environmental impact statement for the project indicate potential water-quality and habitat effects for Currituck Sound associated with the b

Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989–2013
As the population of the Triangle area in central North Carolina increases, the demand for good quality drinking water from streams and lakes within the upper Neuse and upper Cape Fear River Basins also increases. The Triangle area includes Raleigh, Cary, Research Triangle Park, Durham, Chapel Hill, and the surrounding communities. The U.S. Geological Survey examined temporal trends in water quali

Monitoring storm tide and flooding from Hurricane Matthew along the Atlantic coast of the United States, October 2016
IntroductionHurricane Matthew moved adjacent to the coasts of Florida, Georgia, South Carolina, and North Carolina. The hurricane made landfall once near McClellanville, South Carolina, on October 8, 2016, as a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. The U.S. Geological Survey (USGS) deployed a temporary monitoring network of storm-tide sensors at 284 sites along the Atlan

Effect of land-applied biosolids on surface-water nutrient yields and groundwater quality in Orange County, 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. Some independent studies and

Characterization of nutrients and fecal indicator bacteria at a concentrated swine feeding operation in Wake County, North Carolina, 2009-2011
Hydrologic and water-quality data were collected during October 2009–January 2011 to characterize nutrient and bacteria concentrations in stormwater runoff from agricultural fields that receive wastewater originating at a swine facility at North Carolina State University's Lake Wheeler Road Field Laboratory (LWRFL) in Wake County, North Carolina. The swine facility consists of six swine houses, tw
