When the pandemic started, the province was testing the population and updating the number of COVID cases daily. But four years on, testing has stalled and the main way to get a snapshot of the COVID picture is through wastewater.

Reducing road salt use 'not something that can wait' as Ontario lakes see oxygen depletion, researcher says
The move to reduce the amount of road salt during the winter months can't wait because Ontario's groundwater and lakes are showing "very rapid salinization," researchers at the University of Waterloo say. "We actually use a lot of salt, and salt is a very effective way to keep roads, sidewalks and parking lots free of ice, and that, of course, is important in terms of ensuring the safety of road users and pedestrians," said Philippe Van Cappellen, a professor and researcher at the school, as well as the Canada Excellence Research Chair Laureate in Ecohydrology
How Waterloo region's water services are preparing for future climate change challenges
With Waterloo region's climate projected to be more extreme in the coming decades, officials with the region's water services are already thinking of how to adapt to future changes and challenges. Adapting current infrastructure and future builds to climate change takes time and a lot of planning, said Kaoru Yajima, a senior engineer with the region's water services. It's why that work has already been underway for several years. "We've been seeing changes in the climate for some time. It's not like it just happened today or last year. It's been coming around for some time and we knew that we had to plan," he told CBC Kitchener-Waterloo.
Wastewater testing shows Omicron subvariant circulating in Waterloo region
The University of Waterloo's wastewater monitoring shows an Omicron subvariant has been detected in Waterloo region. The BA.2 subvariant appears to be even more transmissible than the original Omicron mutation of COVID-19, says Dr. Hsiu-Li Wang, medical officer of health for the Region of Waterloo, but there's no evidence that it is a more severe mutation. The samples came from the water treatment plant in the City of Waterloo on Jan. 4 and 9 and from the University of Waterloo water treatment plant on Jan. 18, researcher Meghan Fuzzen told CBC Kitchener-Waterloo. They were independently confirmed by two different out-of-province labs.
