Scientists monitoring Ottawa's wastewater say detected levels of the coronavirus have taken a turn for the worse over the past 10 days. According to the most recent data, the levels of the coronavirus in Ottawa's wastewater have trended upward since June 5, after steadily declining for weeks. In early April 2021, researchers who measure levels of COVID-19 in Ottawa's wastewater found the highest levels since early June 2020. Delatolla said increases in wastewater levels can often lead reported case totals by a week or more. Delatolla said the delta variant could be playing a hand in the recent increase.
