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 ... -
Evaluation of Fecal Indicator Bacteria Concentrations in Watersheds Served by Varying Densities of Onsite Wastewater Systems in the North Carolina Piedmont
Sanderford, Christa N (East Carolina University, 2018-04-27)Onsite wastewater systems (OWS) are commonly used in North Carolina for wastewater treatment. Wastewater contains elevated concentrations of pathogens. If OWS do not efficiently treat wastewater then high concentrations ... -
Evaluation of the use of Wastewater Based Epidemiology as a Surveillance Tool and the Potential effects of Vaccines and Students Beliefs and Practices in Mitigating the Spread of COVID-19 Among Students at East Carolina University
White, Avian (East Carolina University, 2022-12-01)Worldwide, newly emerging and re-emerging infectious diseases and pathogens have led to increases in the number and frequency of disease outbreaks. Although these disease outbreaks are not new, increases in outbreaks have ... -
The Fate and Transport of Pharmaceuticals and other Personal Care Products Through Groundwater Beneath and Adjacent to Onsite Wastewater Treatment Systems in Eastern North Carolina
Del Rosario, Katie Lynn (East Carolina University, 2013)In the United States, nutrient and pharmaceutical loading into lakes, streams, and estuaries is a problem that has been recognized for decades and is of special concern for many North Carolina (NC) watersheds. Pharmaceuticals ... -
FATE AND TRANSPORT OF WASTEWATER PHOSPHORUS IN THE NORTH CAROLINA COASTAL PLAIN : A COMPARISON OF WATERSHEDS SERVED BY MUNICIPAL AND ONSITE WASTEWATER SYSTEMS
Anderson-Evans, Eliot (East Carolina University, 2013)This study compares the phosphorus (P) treatment efficiency of on-site wastewater systems (OWS) and municipal wastewater treatment systems (MWS) and quantifies impacts each technology has on ground and surface water. ... -

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 ... -
NUTRIENT, BACTERIA, AND SEDIMENT FLUXES IN A NATURAL WETLAND: AN ECOSYSTEM SERVICE OR DISSERVICE?
Underwood, William Jarrod (East Carolina University, 2020-11-17)Some wetlands have been shown to provide ecosystem services including flood water retention, water quality improvement, and habitat for wildlife and aquatic organisms. Wetlands are commonly created and/or restored to provide ... -
ONSITE WASTEWATER SYSTEM NITROGEN CONTRIBUTIONS TO WATER RESOURCES IN THE PIEDMONT OF NORTH CAROLINA
Jernigan, Jordan (East Carolina University, 2016-07-20)Onsite wastewater treatment systems (OWTS) typically process eight to twelve kilograms of nitrogen per system annually. There are approximately two million OWTS in operation in North Carolina. If the mass and concentration ... -
Onsite Wastewater System Phosphate Contributions to Water Resources in the Piedmont of North Carolina
Serozi, Brent D (East Carolina University, 2016-12-13)Major watersheds in North Carolina including portions of the Cape Fear, Neuse, and the Tar-Pamlico Rivers are impaired because of elevated phosphorus (P) loading from point and non-point sources of pollution. Studies ... -
