Non-point source pollutants are the leading cause of water quality degradation. Our research focuses on the biotransformation mechanisms (e.g., plants, bacteria, fungi) of trace organic contaminants to create natural systems-based treatment technologies that improve water quality. Understanding of pollutant transformation processes facilitates low-energy engineered natural treatment systems that are reliable, robust, and resilient. Examples include understanding the fate and transformation of contaminants in stormwater and the use of bioretention systems to capture and degrade pollutants.

  1. […] Greg LeFevre is an assistant professor of environmental engineering and science in the Department of Civil & Environmental Engineering at the University of Iowa and an assistant faculty research engineer at IIHR-Hydroscience & Engineering. He did his BS at Michigan Tech, MS/PhD at University of Minnesota, and postdoc at Stanford University, all in environmental engineering. The focus of his research group is elucidating novel biotransformation products and pathways of emerging contaminants to inform improved design of engineered natural treatment systems for non-point pollutants. Much of Greg’s work has been dedicated to improving bioretention stormwater green infrastructure. […]
