The shock was so great when seven people died from drinking water in Walkerton, Ontario in May 2000, that it forever changed how the provincial government manages and protects its municipal water, says an environment and resource studies professor.

“It was traumatic and it absolutely, completely redefined how we deal with water in Ontario,” says Robert de Loë, a University Research Chair in Water Policy and Governance.  “The idea that people died from drinking water in Ontario was devastating.

“Before Walkerton, we only had guidelines for drinking water,” says de Loë. “Now we have one of the most comprehensive systems in place in Canada.”

An inquiry into the Walkerton tragedy noted that government cutbacks in the 1990s were part of the reason seven people died and thousands more became sick after drinking water contaminated with E. coli bacteria.  As part of how it responded to the tragedy, Ontario created a collaborative process whereby governments, business people and citizens are working together to better protect water sources through Source Protection Planning.

Looking in the mirror

The good news is that most people can see how they affect water. “I can quickly help people see how their behaviour is part of the problem, but also a big part of the solution,” says de Loë. “When you wonder who is going to make the changes, you need to look into the mirror.”

In areas like Waterloo region where most of the drinking water comes from groundwater, people have to think more carefully about how they grow food, store chemicals and operate their businesses.  “Everything we do on land has the potential to impact groundwater,” says de Loë.

All of these changes have the potential to affect what we do around our homes and how we operate our farms and businesses, but de Loë says that since Walkerton  we’ve accepted that stricter regulations and fundamental changes in behaviour are needed to protect the health and safety of citizens.
