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
Iverson, Guy (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 ... -
Controls on Septic System Wastewater Treatment and Shallow Groundwater Quality in Coastal North Carolina
Humphrey, Charles Pittman (East Carolina University, 2009)Excess nitrogen and bacteria concentrations in coastal waters of North Carolina have led to eutrophic conditions, fish kills, and the closure of shellfish waters. Regulatory efforts by the state to reduce nitrogen and ... -
Effects of Urbanization on Stream-Riparian Zone Connection along Low Order Coastal Plain Streams of North Carolina
Robbins, Jeremy J. (East Carolina University, 2017-07-18)Headwater stream reaches, vital areas of exchange between upland and aquatic systems, are commonly affected by stream burial because they constitute a large fraction of total stream length and are more economically feasible ... -
Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
Hardison, Sarah (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 ... -
Geophysical Detection of On-site Wastewater Plumes in the North Carolina Coastal Plain, USA
Smith, Matthew (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 ... -
NUTRIENT AND BACTERIA DYNAMICS OF PACKAGE TREATMENT PLANTS IN COASTAL CARTERET COUNTY, NORTH CAROLINA
Mahoney, Robert N. (East Carolina University, 2016-08-18)Nutrient and bacteria enrichment problems are well documented in the waterways along North Carolina's coast. Surface and subsurface wastewater inputs have been documented as a source of these pollutants in a variety of ... -
Nutrient contributions from septic systems in nutrient-sensitive watersheds: Quantifying nutrient inputs, reduction methods, and economic feasibility
Iverson, Guy (East Carolina University, 2019-04-30)Eutrophication of surface waters is a global issue threatening aquatic ecosystems and recreational opportunities. Nutrient management strategies exist to reduce nutrient inputs from various sources; however, septic systems ... -
Occurrence of Escherichia coli (E coli) and Enterococcus in shallow groundwater adjacent to onsite wastewater treatment systems in Washington, North Carolina
Henry, Keaton A. (East Carolina University, 2012)Onsite wastewater treatment systems (OWTS) have been identified as a potential source of microbial contamination of groundwater. Microbial indicators, such as E.coli and Enterococcus, are transported from these systems ...
