Groundwater/Surface Water Interaction near Ellerbe Creek, Durham, NC

Falls Lake has been 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 (North Carolina Department of Environment and Natural Resources, Division of Water Quality, 2010a).  The North Carolina Environmental Management Commission has adopted nutrient management...

Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed

Floodplain and wetland areas provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. The loss of floodplain functionality due to land use conversion and degradation reduces the provisioning of these services. Assessing, quantifying, and valuing floodplain ecosystem services provide a framework to estimate how floodplain...

Chattahoochee River, Georgia BacteriAlert

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...

Widespread occurrence and potential for biodegradation of bioactive contaminants in Congaree National Park, South Carolina

Organic contaminants with designed molecular bioactivity, such as pesticides and pharmaceuticals, originate from human and agricultural sources, occur frequently in surface waters, and threaten the structure and function of aquatic and terrestrial ecosystems. Congaree National Park in South Carolina (USA) is a vulnerable park unit due to its location downstream of multiple urban and...

Water quality characterization of bridge deck runoff in North Carolina

There is evidence that bridge deck runoff has a relatively high loading of a variety of constituents such as nutrients, solids, pesticides, metals, and polycyclic aromatic hydrocarbons (PAHs). Information on the quality of bridge deck runoff in North Carolina is, however, lacking. Stormwater permits are designed to reduce nonpoint source loadings of anthropogenically derived constituents to...

NAWQA Regional Stream Quality Assessment

How is stream ecology affected by chemical and physical stressors in small streams? The U.S. Geological Survey (USGS) is addressing this question through studies of relations between stressors and stream ecology across large regions of the United States.

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...

Triangle Area, NC, Water Supply Monitoring

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...

Assessment of Groundwater Availability in Aiken County, South Carolina

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.

Stratification and Water Quality of Jordan Lake, North Carolina

The New Hope arm of Jordan Lake, located in Chatham County, North Carolina, serves as a drinking-water supply for the Towns of Cary, Apex, and Morrisville. The reservoir is listed as impaired due to nutrient over-enrichment and occasionally experiences algal blooms and fish kills.

In order to evaluate effects of installing a vertical-mixing system on the New Hope arm of Jordan Lake, the...

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...

Roanoke River Water-Quality Monitoring and Modeling, N.C.

The relations among river flow, floodplain water level, and instream dissolved-oxygen (DO) concentrations are important but poorly understood for the Roanoke River. Flooding and floodplain inundation no longer follow a natural seasonal pattern of flooding in the winter and occasionally in the fall, and lower flows throughout the remainder of the year, but are primarily governed by upstream...
