Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
(East Carolina University, 1/13/16)
Onsite wastewater treatment systems (OWS) are a potential non-point source of pollution that can result in water quality degradation in groundwater and surface water. Locating OWS wastewater plumes in the subsurface often ...
Stratigraphy and Petroleum Geology of the Blue Monday Sandstone, Central West Virginia
(East Carolina University, 2011)
The Upper Mississippian Blue Monday sandstone is a primarily gas producing unit found in several central West Virginia gas fields. The purpose of this study was to characterize the stratigraphy and petroleum geology as ...
QUANTITATIVE COMPARISON OF 2D POROSITY AND PORE GEOMETRY BETWEEN THE UPPER CASTLE HAYNE AQUIFER, NORTH CAROLINA, AND THE BISCAYNE AQUIFER, FLORIDA, USING IMAGE AND GEOSPATIAL ANALYSIS
(East Carolina University, 2012)
Karst aquifers are vital sources of groundwater for domestic and industrial use in many parts of the world. To sustain rising population throughout the southeastern United States, karst aquifers are increasingly exploited ...
A comparison of watershed nitrogen loading and watershed nitrogen exports from on-site wastewater treatment systems and centralized sewer systems in the North Carolina Coastal Plain
(East Carolina University, 2013)
Elevated nitrogen (N) concentrations in groundwater may cause adverse effects to adjacent surface water bodies. In North Carolina, half of the residences use on-site wastewater treatment systems (OWTS), yet they are typically ...
Spatial and Temporal Variability in Surficial Seabed Character, Waipaoa River Margin, New Zealand
(East Carolina University, 2012)
The Waipaoa River margin, located off the northeast coast of the North Island of New Zealand, provides an opportunity to examine shelf-wide sediment dynamics in a coastal setting. The region is characterized by a narrow ...
Macondo-1 well oil-derived polycyclic aromatic hydrocarbons
(East Carolina University, 2012-01-14)
Mesozooplankton (>200 mm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ...
ECU researchers discuss risky oil spill clean-up
(East Carolina University, 2010)
Sampling in salt marshes for high resolution geological studies
(East Carolina University, 2011-01)
Video demonstrating how to take core samples for geological research into sediment formations.
Geophysical Detection of On-site Wastewater Plumes in the North Carolina Coastal Plain, USA
(East Carolina University, 2014)
Nonpoint source pollution (NPS) continues to be the leading cause of water quality degradation in the United States. On-site wastewater systems (OWS) contribute to NPS; however, due to the range of system designs and ...
Analyzing Estuarine Shoreline Change in Coastal North Carolina
(East Carolina University, 2009)
With continued climate change, sea-level rise, and coastal development, concern about shoreline dynamics has expanded beyond oceanfront areas to encompass more protected coastal water bodies, such as estuaries. Because ...
