Biotransformation of Contaminants in Natural Water Treatment Systems

Research Focus

Non-point source pollutants are the leading cause of water quality degradation. Engineered Natural Treatment Systems take advantage of low-energy biological processes to capture and transform contaminants. Our research focuses on the fundamental mechanisms related to the microbial and vegetative biotransformation of emerging contaminants in aquatic environments.

Specifically, we focus on the discovery of novel transformation products and pathways of emerging contaminants in the environment. This work informs understanding of contaminant fate and the optimization of resilient water infrastructure through sustainable natural systems-based treatment technologies to improve water quality for ecosystem and human health.
