Assessing The Impact Of A Constructed Wetland Biome On The Ecosystem Health Of Cedar Run, Thomas Vasilopoulos, Casey Lee
Assessing The Impact Of A Constructed Wetland Biome On The Ecosystem Health Of Cedar Run, Thomas Vasilopoulos, Casey Lee
Senior Honors Projects, 2010-2019
A wetlands ecosystem is defined as “an area saturated by surface or groundwater at a frequency or duration sufficient to support...a prevalence of vegetation typically adapted for life in saturated soil conditions” (Batzer and Sharitz, 2007). Wetlands serve as biofilters and thus have been used to treat sewage and wastewater, as well as to restore the health of polluted water systems. Solly Walker and Lorinda Palin, owners of a certified natural and biodynamic farm called Avalon Acres located in Broadway, Virginia, constructed a wetland two years ago, using the stream, Cedar Run, that flows through their property. Pollution from agricultural …

Performance Quantification Of Extensive Green Roof Substrate Blend: Expanded Shale And Biochar, James Sheats
Masters Theses, 2010-2019
Urban stormwater management practices often involve the redirection of runoff to local waterbodies. As such, the quality of runoff directly affects the condition of these receiving waters. Green roofs offer many benefits to the urban environment including attractive aesthetics, thermal insulation for buildings and stormwater runoff reduction. Unfortunately, in order to promote the spread of vegetation, fertilization is often practiced that can lead to elevated nutrient concentrations in runoff and, ultimately, nearby streams, rivers and bays. Different amounts of biochar, pyrolyzed biomass, were added to model green roof trays to test for the ability of this charcoal-like substance to prevent …
