Wastewater Surveillance at the Guelph Campus

The University of Guelph monitors its residences’ wastewater for SARS-CoV-2, the virus that causes COVID-19, to help identify and act on risks in order to further protect our community. 

The virus may be shed in the feces of those infected with SARS-CoV-2 days before they begin to feel ill. This wastewater surveillance scans samples in a non-invasive way. Samples are an aggregate of all wastewater coming from a particular residence building, and cannot identify any particular person.

Green – low to no signal

Yellow – low to moderate signal

Red – moderate to high signal

– The signal compared to the previous day has increased, decreased or remained the same

Wastewater results from each building are reviewed daily. The situation is referred for review if the analysis indicates:

  • two consecutive daily yellow or red signals that trend upward, or
  • results that are otherwise notable.

The panel will consider the results in the context of other known factors (e.g., known cases, vaccination rates, etc.).

Panel members:

  • Alison Burnett, Student Wellness
  • Lawrence Goodridge, Food Science
  • Marc Habash, Environmental Science
  • Pat Kelly, Student Housing
  • Andrew Papadopoulos, Population Medicine
  • Liz Snyder, Research Communications
  • Scott Weese, Pathobiology
  • Jennifer Wesley, Office of Research/EHS (coordinator)
  • Lise Trotz-Williams, Wellington Dufferin Guelph Public Health

Following their review of notable results, the Panel may recommend a response that could include actions such as communications, restricting building access and/or testing community members.
