SARS-CoV-2 signal measured in municipal wastewater using the N200 assay with the Universal probe in a multiplexed rection (Log scale, copies/mL). Some samples were included that were above the limit of detection (LOD) but below the limit of quantification (LOQ) as indicated in the figure. Samples from the Peel (GE Booth and Clarkson), York (Humber AMF and Warden) and Waterloo (Waterloo and Kitchener) Regions were collected during the period encompassing both the introduction of Omicron into these communities and the concomitant reduction of the endemic Delta VOC.
