Nitrogen Removal Performance Of Roadside Bioretention Cells Amended With Aluminum-Based Drinking Water Treatment Residuals, Carl Betz
UVM Patrick Leahy Honors College Senior Theses
Urban stormwater runoff transports a suite of environmental pollutants that can degrade the quality of receiving waters. Bioretention cells, a type of engineered raingarden, have been shown to reduce runoff volumes and remove a variety of pollutants. The ability of conventional bioretention cells to remove nitrogen and phosphorus, however, is variable and bioretention soil media can act as a net exporter of nutrients. This is concerning as excess loading of nitrogen and phosphorus can lead to eutrophication of surface waters. Drinking water treatment residuals (DWTR), metal (hydr)oxide rich byproducts of the drinking water treatment process, have been studied as an …

Soil Carbon Conservation, Land Use Change, And Sustainable Agriculture In The Peruvian Amazon, Julia L. Petty
UVM Patrick Leahy Honors College Senior Theses
The task of integrating the scattered needs of both people and nature at a multitude of scales remains daunting in the field of environmental science. This study examined one facet of this pursuit by determining the potential sustainability and ecosystem services provided by a proposed agroforestry initiative in Loreto, Peru. Specifically, the study evaluates the mechanisms and dynamics of soil carbon sequestration as a response to land use change in the Peruvian Amazon. Both fine root biomass and soil organic carbon (SOC)- measured as loss-on-ignition- was analyzed over a vertical gradient in a primary tropical forest, a traditional slash-and-burn cultivated …
