The Effect Of Vegetated Roofs On Acid Precipitation Runoff, Jennifer Gillen
The Effect Of Vegetated Roofs On Acid Precipitation Runoff, Jennifer Gillen
Geology Theses and Dissertations
Vegetated, or “green” roofs are used in urban architecture and sustainable building to capture stormwater and enhance urban wildlife. Most research to date has focused on their water retention capabilities, but green roofs also have the potential to treat anthropogenic acid precipitation in urban environments. More specifically, green roofs could reduce sulfate, nitrate and hydrogen ion concentrations in runoff. One previous study has demonstrated that nitrate was reduced in water draining from a green roof (Berndtsson, et al. 2006), but this unpublished thesis appears to be the first comprehensive study of the effects of vegetated roof materials on major ions …
Road Salt Application And Its Effects On Sodium And Chloride Ion Concentrations In An Urban Stream Patroon Creek, Albany, Ny, Elizabeth K. Erickson
Road Salt Application And Its Effects On Sodium And Chloride Ion Concentrations In An Urban Stream Patroon Creek, Albany, Ny, Elizabeth K. Erickson
Geology Theses and Dissertations
The application of road salt in an urban watershed leads to increased sodium and chloride concentrations in surface water and groundwater, which can adversely affect aquatic ecosystems, and may have consequences for soil cation exchange. This study focuses on the spatial and temporal variations in sodium and chloride concentrations in Patroon Creek, Albany County, New York, a tributary of the Hudson River. For two years, weekly surface water samples were gathered from 7 sites along Patroon Creek for major ion concentrations as measured by ion chromatography. Additionally, a USGS gage on Patroon Creek measures specific conductivity, water temperature, stage, and …
