THE WATER INNOVATION & REUSE LAB
Department of Civil Construction & Environmental Engineering
San Diego State University

WIRLab trains and mentors undergraduate and graduate students from diverse 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 source waters, streams, and groundwater.
WIRLab is led by Dr. Natalie Mladenov, Professor and William E. Leonhard Jr. Chair in the Department of Civil, Construction, & Environmental Engineering at SDSU.
Please contact Dr. Mladenov (at nmladenov @ sdsu.edu) or stop by E404 for a tour.
Kumeyaay Land Acknowledgement
For millennia, the Kumeyaay people have been a part of this land. This land has nourished, healed, protected and embraced them for many generations in a relationship of balance and harmony. As members of the San Diego State University community, we acknowledge this legacy. We promote this balance and harmony. We find inspiration from this land, the land of the Kumeyaay.

ABOUT WIRLAB

San Diego River Studies
WIRLab's collaborative research with the Safe Water Lab, Disturbance Hydrology Lab, and Public Health at SDSU, reveals that leaky sewers have a major influence on water quality in the San Diego River during storms and that waste associated with homeless encampments is less of a contributor. For more information, please see the Executive Report, which summarizes our findings, and the Final Report, which includes detailed results.
