A Pilot Scale Study of Denitrifying Bioreactors Paired with Phosphate Sorbents
Lindley, Ann Marie (East Carolina University, 2023-08-18)Denitrifying bioreactors are commonly utilized as a best management practice in agricultural systems to reduce nitrate in drainage waters. The USDA recommends the utilization of woodchips as a carbonaceous substrate to ... -
Effects of influent composition and substrate type on nitrate and Escherichia coli removal in laboratory-scale denitrifying bioreactors
Brink, Shannon E (East Carolina University, 2023-01-05)Escherichia coli (E. coli) and nitrate (NO3-) are common contaminants found in waters down gradient of wastewater sources such as septic tanks and agricultural operations. Carbon-rich subsurface denitrifying bioreactors ... -
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, ... -
PERSPECTIVES ON WATER MANAGEMENT FROM LOCAL WATER DECISION MAKERS IN A COASTAL REGION
Bunnell, Anne E (East Carolina University, 2023-01-05)The effects of climate change are already apparent in eastern North Carolina. Higher than average global temperatures have been implicated in more extreme weather events, with more frequent and intense storms and prolonged ... -
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 ...
