Recent environmental regulations have required development and installation of stormwater best management practices (BMPs) or Green Stormwater Infrastructure (GSI) for removal stormwater runoff pollutants. Limited understanding of the physical and chemical processes occurring within these facilities has largely resulted in assignment of assumed long-term removal efficiencies which can have profound future environmental and economic consequences. A more complete understanding of the actual removal processes and long-term efficiencies through long-term standardized monitoring is required to refine design standards for future GSI. Due to differences in the physiochemical processes that occur between non-proprietary GSI types (e.g. bioretentions, sand filters, permeable pavement, etc.), a single monitoring protocol is inadequate for addressing variable stormwater GSI. Therefore, the objective of this study is to develop comprehensive monitoring protocols for implementation on a regional and national level to yield a uniform and systematic approach for quantification of GSI efficiency for unique non-proprietary facility types. Existing national (Technology Assessment Protocol – Ecology [TAPE], Technology Assessment Reciprocity Partnership [TARP], etc.) and local monitoring standards were reviewed and summarized to aid in the development of recommendations that include a process for selecting candidate GSI within a community for monitoring. Proposed monitoring standards and methods, including field, lab and data analysis methods, will be implemented on several selected case study GSI monitoring projects within Fairfax County, Virginia.
Marcus recently finished his Ph.D. in Virginia Tech's Via Department of Civil and Environmental Engineering, and is now a Research Scientist in Dr. Randy Dymond’s research group. His main research focus is on understanding and improving the long-term interaction between humans, our built infrastructure, and the natural ecosystem in urban watersheds, using innovative engineering, economic, and policy mechanisms. He specializes in urban watershed planning, hydrologic uncertainty, stormwater policy, and geographic information systems. Marcus received his MS in Civil Engineering from Virginia Tech in 2013, and a BS in Civil Engineering from the University of Alabama in 2009. He also has consulting experience with AECOM’s Community Infrastructure group in the Houston, Texas office.
