Assessment of Nitrate Concentrations in Groundwater Near an Onsite Wastewater System Before and After Installation of a Permeable Reactive Barrier
Mebane, Lucas (East Carolina University, 2023-05-08)There are approximately 2 million onsite wastewater systems (OWS) in North Carolina that provide soil-based treatment of wastewater. Wastewater contains elevated concentrations of environmental pollutants including nitrogen. ... -
Influence of Permeable Interlocking Concrete Paver Performance on Infiltration and Temperature in and Urban Watershed
Farley, Lori (East Carolina University, 2022-07-26)Urbanization is a form of land use change that typically results in an expansion of impervious surfaces and increased soil compaction. These urban-induced changes in watershed hydrology can result in stream channel erosion, ... -
NITROGEN AND BACTERIA TREATMENT EFFICIENCY OF ONSITE WASTEWATER SYSTEMS IN THE PIEDMONT OF NORTH CAROLINA
Jernigan, Jordan (East Carolina University, 2023-12-01)Onsite wastewater treatment systems (OWTSs) are commonly used in rural areas for wastewater disposal. These systems can contribute elevated concentrations of nutrients and bacteria into water resources, resulting in potential ... -
Surface water and groundwater quality impacts at a swine CAFO with a capped lagoon system in eastern North Carolina
Richardson, Lauren James (East Carolina University, 2023-01-26)Waste from concentrated animal feeding operations (CAFOs) is traditionally stored in open lagoons and the liquid wastewater is periodically applied to nearby sprayfields. Capping lagoons with an impermeable cover have been ...
