SPARROW Modeling for North Carolina Watersheds
In North Carolina, excessive nutrient and sediment loadings have contributed to the degradation of surface-water quality across the state as a result of agricultural activities and population growth increases. To further understand the influences of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced...

SPARROW model dataset for total suspended solids in North Carolina, including simulated stream loads
To better understand the influence of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) (Schwarz and others, 2006; Alexander and others, 2008) model. The framework is used to relate water-quality monitoring data to sources and watershed characterist
SPARROW model datasets for total nitrogen and total phosphorus in North Carolina, including simulated stream loads

Five Hydrologic and Landscape Databases for Select National Wildlife Refuges in Southeastern United States
Five hydrologic and landscape databases were developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, for select National Wildlife Refuges (NWRs) in southeastern United States: (1) the Cahaba River NWR and contributing watersheds in Alabama, (2) the Caloosahatchee and J.N. "Ding" Darling NWRs and contributing watersheds in Florida,
Five hydrologic and landscape databases for selected National Wildlife Refuges in the Southeastern United States
This report serves as metadata and a user guide for five out of six hydrologic and landscape databases developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, to describe data-collection, data-reduction, and data-analysis methods used to construct the databases and provides statistical and graphical...

Water quality and bed sediment quality in the Albemarle Sound, North Carolina, 2012–14
The Albemarle Sound region was selected in 2012 as one of two demonstration sites in the Nation to test and improve the design of the National Water Quality Monitoring Council’s National Monitoring Network (NMN) for U.S. Coastal Waters and Tributaries. The goal of the NMN for U.S. Coastal Waters and Tributaries is to provide information about the...

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...

Baseline well inventory and groundwater-quality data from a potential shale gas resource area in parts of Lee and Chatham Counties, North Carolina, October 2011-August 2012
Records were obtained for 305 wells and 1 spring in northwestern Lee and southeastern Chatham counties, North Carolina. Well depths ranged from 26 to 720 feet and yields ranged from 0.25 to 100 gallons per minute. A subset of 56 wells and 1 spring were sampled for baseline groundwaterquality constituents including the following: major ions;...
