What is the chart showing me?
Each chart shows the amount of COVID-19 virus present per litre of wastewater prior to treatment at one of Metro Vancouver’s five wastewater treatment plants. Results are sorted by sewerage areas, which are defined catchment areas around each wastewater treatment plant. Wastewater from homes and businesses within each area is collected and directed to a specific wastewater treatment plant.
The science of COVID-19 is evolving rapidly. The data shown in the charts should be considered as general trends and not specific daily measurements.
While SARS-CoV-2 can be shed in the feces of people with COVID-19, there is no information to date that anyone has become sick with COVID-19 because of direct exposure to treated or untreated wastewater.
