Wastewater Surveillance at the Guelph Campus
The University of Guelph monitors the wastewater from residence buildings for SARS-CoV-2, the virus that causes COVID-19. Monitoring wastewater for the virus is proving an important surveillance tool.
The virus may be shed in the feces of those infected with SARS-CoV-2 days before they begin to feel ill which allows for the early detection of COVID-19 infection on campus. This wastewater surveillance scans samples in a non-invasive way by collecting sanitary sewage wastewater and analyzing evidence of the virus using PCR. Samples are an aggregate of all wastewater coming from a particular residence building and cannot identify any particular person.
The wastewater dashboard below captures information from Guelph and Ridgetown campus residence buildings.
Green – low to no signal
Yellow – low to moderate signal
Red – moderate to high signal

- This dashboard is updated when samples are tested (three times per week for Guelph campus residences and two times per week for the Ridgetown campus residence). Testing takes place on business days, excluding holidays. However, there are some days data cannot be collected for various reasons, for example inclement weather.
- The line graph is based on a rolling seven-day average. Only days where data has been collected are included in this calculation.

- College Avenue and West Residence
- East Townhouses and Village
- Johnston Hall
- Lambton Hall
- Maritime Hall
- Mills Hall
- Mountain Hall

Sampling and analysis are conducted by University of Guelph researchers led by the following interdisciplinary team:
- Lawrence Goodridge, Food Science (Laboratory analysis)
- Marc Habash, Environmental Sciences (Laboratory analysis)
- Heather Murphy, Pathobiology (Wastewater expert)
- Ed McBean, Engineering (Wastewater expert)
The team relies on critical support and assistance from the University’s Physical Resources Department, particularly David Bezanson and Matt Vuk.Link to this tab
As wastewater results from each building are reviewed, the Wastewater Surveillance Panel meets to discuss trends. Following their review, the Panel may recommend a response that could include actions such as communications, restricting building access and/or testing community members.
