Collection and Interpretation of Near Real-Time Surface-Water Quality and Flow Data at Selected Sites in the Waccamaw and Pee Dee River Basins Horry County, South Carolina

This proposed investigation aims to increase the frequency of surface-water quality data collection and initiate stream-flow data collection near existing DHEC ambient sites in Horry County. State-of-the-art water-quality and flow sensors that can collect and report water quality and stream-flow data in near real-time will be installed at 3 sites that are currently on the 303(d) list for SC in...

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...

Water Use Trends in Alabama

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined in...

Submarine canyons influence macrofaunal diversity and density patterns in the deep-sea benthos

Submarine canyons are often morphologically complex features in the deep sea contributing to habitat heterogeneity. In addition, they act as major conduits of organic matter from the shallow productive shelf to the food deprived deep-sea, promoting gradients in food resources and areas of sediment resuspension and deposition. This study focuses on...
