Water Use in North Carolina, 2010

In North Carolina and across the Nation, water is a vital resource and it is used for a variety of purposes. Water use for 2010 was estimated for each county in North Carolina using data obtained from various Federal and State agencies and other sources. Estimates of water use in North Carolina were developed for the categories of public supply, domestic, industrial, mining, aquaculture,...

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...

Mid-Currituck Bridge Water Quality, Currituck Sound, North Carolina

The North Carolina Department of Transportation is planning to make transportation improvements in the Currituck Sound area by constructing a three-lane bridge from U.S. Highway 158 just south of Coinjock, North Carolina, to State Highway 12 on the Outer Banks just south of Corolla, North Carolina. From Aug 2011 to early 2018, the USGS will be collecting regular water-quality samples as well...

Evaluation of Nutrients in Durham County, North Carolina, Urban Streams

Falls Lake and Jordan Lake are included in the North Carolina Division of Water Quality's 303(d) list of "impaired" waters due to violations of the State chlorophyll-a standard caused by excessive nutrient inputs. Scientific data are needed allocate resources to achieve nutrient reduction targets have been adopted for the Falls Lake and Jordan Lake watersheds for stormwater, as well as for...

Flood Frequency Information

Reliable estimates of the magnitude and frequency of floods are essential for such things as the design of transportation and water-conveyance structures, flood insurance studies, and flood-plain management. Flood-frequency estimates are particularly important in densely populated urban areas. The U.S. Geological Survey (USGS) is using a multistate approach to update methods for determining...

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...

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...

Application of Phreatophytes to Remediate Contaminated Groundwater Before Discharge to Protected Surface-Water Systems

State environmental agencies are charged with the protection of groundwater and surface-water systems from water-quality degradation. Although the point-source discharge of wastes to surface waters is allowed up to permitted levels, contaminant releases from non-point sources, such as the discharge of contaminated groundwater, is not regulated. A common cause of groundwater contamination is...

Groundwater Awareness Week is March 6-12

Groundwater is not a single vast pool of underground water; rather, it is contained within a variety of aquifer systems. Each of these aquifers has its own set of questions and challenges. From large drawdowns in the Great Plains aquifer to arsenic in some wells in New England, this episode of CoreCast highlights six different USGS groundwater studies all across the United

Effects of Urbanization on Stream Ecosystems

Development can have negative effects on streams in urban and suburban areas. As a watershed becomes covered with pavement, sidewalks, and other types of urban land cover, stream organisms are confronted with an increased volume of storm water runoff, increased exposure to fertilizers and pesticides, and dramatic changes in physical living spaces within the stream itself.
