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...

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...

Data-driven, multi-model workflow suggests strong influence from hurricanes on the generation of turbidity currents in the Gulf of Mexico

Turbidity currents deliver sediment rapidly from the continental shelf to the slope and beyond; and can be triggered by processes such as shelf resuspension during oceanic storms; mass failure of slope deposits due to sediment- and wave-pressure loadings; and localized events that grow into sustained currents via self-amplifying ignition. Because...
