UC Davis monitors campus wastewater for COVID-19 in our campus community. Data below are interactive, so you can select date ranges and move your pointer over the graph for additional details.
Data Sources and Definitions
Wastewater data is updated on a weekly basis with information provided by Associate Professor Heather Bischel's lab (Department of Civil and Environmental Engineering).
- Normalized SARS-CoV-2 concentration: Or N/PMMoV. Presented as a 7-day moving average, this normalized concentration measures the amount of the SARS-CoV-2 N gene, which is present in nearly all variants of the virus. In this graph, the concentration of the N gene is normalized in comparison to the concentration of pepper mild mottle virus, or PMMoV, which serves as an indicator of “fecal strength” of each sample as one of the most abundant viruses found in human waste. This helps to normalize samples based on population size, rain or water usage. Data for other Yolo County communities can be found on the Healthy Central Valley Together website.
- Where do I find wastewater data for the city of Davis?
- More data from wastewater monitoring, including multiple viruses from surrounding cities, can be found on the Healthy Central Valley Together wastewater data website. This website includes wastewater data from the cities of Davis, Woodland and other Central Valley locations.
- Where is COVID-19 data for the city of Davis?
- The Yolo County data on the California Department of Public Health COVID-19 Dashboard provides data about new coronavirus cases, deaths, testing, positivity and vaccination rates in Yolo County. UC Davis reports positive results from both the asymptomatic kiosk testing and from the Student Health and Wellness Center (as a medical provider) to the State of California, so that Yolo County can include campus data in its dashboard. Test results for students and employees who have been tested by other medical providers are otherwise included in COVID-19 data for their county of residence. (Updated July 14, 2022)
