Calgary and Edmonton COVID-19 wastewater readings trending downward

The data from wastewater is considered a better indicator of how a city is doing at this point in the pandemic, particularly at a time when the province is rationing tests to high-risk groups and many people who have contracted COVID-19 are not showing up on provincial case totals. Wastewater testing measures COVID-19 levels across an entire city and officials can get a big picture perspective sooner than relying on just nasal testing.
