Bacteria that clean groundwater

University Professor Elizabeth Edwards received the Royal Society of Canada’s 2026 Miroslaw Romanowski Medal for her work on cleaning contaminated groundwater. Her lab’s KB-1 culture breaks down chlorinated solvents completely, without leaving a carcinogenic byproduct, and she directs U of T’s BioZone centre.

Elizabeth Edwards of chemical engineering is the 2026 recipient of the Royal Society of Canada’s Miroslaw Romanowski Medal, which recognizes scientific work on environmental problems. Her research covers contaminated groundwater, wastewater treatment and anaerobic digestion.

One of the microbial cultures her lab developed, called KB-1, is dominated by unusual bacteria that dechlorinate chlorinated solvents, among the most common groundwater contaminants. It achieves complete dechlorination of chlorinated ethenes without accumulating vinyl chloride, a carcinogen.

Edwards is the founding director of BioZone, a U of T research centre that fosters collaboration between academia and industry. Her earlier honours include the Killam Prize in Engineering. Dean Chris Yip called her work pioneering.

Until the next issue

The class keeps arriving.

One hundred and thirteen stories end this issue, but the university doesn't pause between them. A new orientation week is already being planned; a lab somewhere on campus is already running the next experiment. Alumni Digest will be there in October for the next one.
