Wastewater-based COVID data

A new section of Stanford’s COVID dashboards now provides data showing the prevalence of the virus based on analysis of campus wastewater. The project, developed and coordinated by Stanford’s Department of Civil & Environmental Engineering, collects and analyzes samples from a large sewer main that contains wastewater from more than 150 buildings and 10,000 people on campus. Samples are typically collected six days a week, followed by analysis and posting of the results over the next 24-48 hours.
