WIRLab trains and mentors undergraduate and graduate students from all groups to take on environmental challenges in water scarce environments by conducting research on sustainable water and sanitation technologies and biogeochemical processes in natural and engineered systems. Current projects investigate the transformation and persistence of emerging chemicals in anaerobic and aerobic decentralized water reuse systems, sources of anthropogenic contaminants in urban rivers, water quality response to stream restoration, the fate of microplastics in the environment, and rapid fluorescence-based tracking of organic contaminants in surface water and groundwater.
