World Water Day 2022

CivMin Researchers on cleaning and protecting our most valuable resource

Most Canadians have unlimited access to clean drinking water, but that’s a privileged existence unknown to billions of other people living on this planet.  

And if you don’t have to think about where your water comes from or what’s in your water, then life is easy—but it might not be that way forever.  

Fortunately, there are many brilliant minds right here at University of Toronto who are not only studying what’s in our water, but who are also looking at new and innovative ways of cleaning or recycling it. 

For World Water Day, we spoke with several faculty members who are engineering new solutions to preserve and protect our most precious resource.

This year’s theme for World Water Day 2022 is ‘Groundwater: ‘Making the Invisible Visible’ and groundwater.

Every year millions of tonnes of plastic make their way into our waterways. Over time, larger plastics break down into tiny pieces that can infiltrate lakes and rivers which serve as sources of drinking water.

In a city like Toronto, the water never stops running. There’s always pressure conveniently pushing clean water into our homes for on-demand consumption. But that’s not how the whole world works.

Can we use naturally occurring minerals such as titanium dioxide to purify small amounts of water in remote communities or campgrounds?

Would you wake up one morning and drink a glass of water that your neighbour down the street used a few days ago to take a shower?
