Impacts of biota on bioretention cell function during establishment in the Midwest
… region-specific effects of biota on function of bioretention cells, a lysimeter study was conducted at Kansas State University to determine how earthworms and native Kansas grasses impact runoff treatment and hydraulic function of a bioretention cell. This study also employed the Comprehensive …

Does it pay to be mature? Assessing the performance of a mature bioretention cell seven years post-construction
Bioretention cells (BRCs) are low-impact development stormwater management structures that integrate water quantity and quality management. Although BRCs have a predicted design life of about 25 years, most current research focuses on performance of cells less than two years old. This project …

Effects of Using Clay Nanoparticles as a Soil Amendment to Remove Nitrate from Stormwater
… stormwater prior to discharge downstream. A bioretention cell is used to treat stormwater pollutants such as nitrate, phosphorus, total suspended solids, and metals. Past research has indicated that the removal efficiency of nitrate by bioretention cells greatly varies from a 75% reduction in …

Stormwater Treatment by Two Retrofit Infiltration Practices
… project was to evaluate the effectiveness of a bioretention cell and a CU-Structural Soil™ infiltration trench. BMP construction was completed in July 2007. Twenty-nine precipitation events were monitored over a period of five months between October 2007 and March 2008. For each storm, inflow …

Using Bioretention Retrofits to Achieve the Goals of Virginia's New Stormwater Management Regulations
… channel erosion. This study models different bioretention cell sizes in a developed watershed in Blacksburg, Virginia to determine the "performance" at both the sub-watershed and watershed levels. In addition, models of "optimal" bioretention cells sized to meet the RRM for each sub-watershed …

Performance Evaluation of a Low Impact Development Retrofit for Urban Stormwater Treatment
… included four in-line grass swales followed by a bioretention cell with a gravel base. The facility retained 85% of the rainfall. Influent and effluent pollutant loads were calculated using three common substitution methods for datasets censored by values below the analytical detection limit. The …

Changes in Stormwater Thermal Loads Due to Bioretention Cells
… event, resulting in higher runoff temperatures. Bioretention cells are a common stormwater control practice identified as a possible thermal mitigation practice in urban watersheds harboring cold-water fish species. However, design specifications vary by locality and few studies have explored how …

OPEs, What Do We Do? Modeling Emissions, Fate, and Mitigation of Organophosphate Esters in Urban Systems
… Toronto air emissions to receiving waters. Using bioretention cells as an example stormwater management technology, I undertook a scoping review of bioretention research. This review found that uptake by vegetation was a potentially important pathway for the fate of PMOCs, requiring further study. …

Characterization and Removal Efficiency Comparison of Bioretention Soil Media Mixtures
<p>Bioretention cells have become a commonly used green infrastructure technique to help infiltrate and remove contaminants from stormwater runoff. Bioretention cells are constructed from a layered or heterogeneous soil mixture designed to optimize their ability to infiltrate influent stormwater …

Sorption and release of dissolved pollutants via bioretention media.
… One such treatment practice is called bioretention, or rain gardens. This thesis discusses the use of bioretention media as a treatment technique for the removal of toxic metals and investigates the release of phosphorus. A review of previous research and the laboratory experiments will …

A Stormwater Management Model for California Polytechnic State University Campus
… plans to build. Permeable Pavements (PPs) and Bioretention Cells (BRCs) were the LID types examined. The LIDs were evaluated based on peak flow and runoff volume reductions they would achieve. The potential reductions were compared for current conditions and the proposed project if LIDs were …
