The Effect Of The Antecedent Dry Conditions On Nitrogen Removal For A Modified Bioretention System, Mackenzie Peterson
USF Tampa Graduate Theses and Dissertations
Eutrophication is defined as the ‘over enrichment’ of a water body from nutrients, resulting in uncontrolled growth of primary producers, leading to periods of oxygen depletion from decomposition of the algal organic matter. According to the 2010 Water Infrastructure Needs and Investment (a U.S. Congressional Report), 40% of U.S. water bodies are contaminated with pollutants, including nutrients. Non-point sources of nutrient pollution are a major cause of this reduction in water quality. One way to decrease eutrophication is to manage nutrients found in stormwater runoff, before they reach a receiving water body.

Water Quality Evaluation Of Tire Derived Aggregate, Richela K. Maeda
Water Quality Evaluation Of Tire Derived Aggregate, Richela K. Maeda
Projects
The primary objective of this study is to investigate the rate that potential water quality contaminants leach from tire-derived aggregate (TDA) as a function of time. A laboratory and field experiment is conducted to provide insight into both controlled and field settings. The laboratory portion of this study also provides a basis for evaluating the effect that alternating periods of wet and dry weather have on the potential water quality impacts of the leachate as compared to the worst-case operating condition, when TDA is constantly submerged (i.e., when placed below the permanent groundwater table). The field experiment is used to …
Modeling Impacts Of Combined Sewer Overflows In Swmm In Cleveland, Ohio, Zoe A. Miller
Modeling Impacts Of Combined Sewer Overflows In Swmm In Cleveland, Ohio, Zoe A. Miller
Dissertations, Master's Theses and Master's Reports
Despite its legacy of pollution, the City of Cleveland, Ohio, has historically been at the forefront of water quality management. Today, the Northeast Ohio Regional Sewer District (NEORSD), which serves the Greater Cleveland area, is following a consent decree with the State of Ohio to minimize combined sewer overflows (CSOs), along with implementing an integrated Clean Water Act planning study to prioritize infrastructure improvements with a broader view of water quality objectives. This report summarizes an urban watershed modeling effort to support the integrated planning (IP) process. Specifically, the development, calibration, and validation of the EPA Stormwater Management Model (SWMM) …
