Orange County is actively participating in the Centers for Disease Control (CDC) Health and
Human Services (HHS) National Wastewater Surveillance System. The program monitors wastewater from water reclamation
facilities across the United States for concentrations of SARS-CoV-2 RNA. The data collected by the program helps
the CDC and local authorities better understand the spread of the virus in communities. The concentrations tested
reflect both symptomatic and asymptomatic residents, alerting participating organizations to spikes in infections
four to ten days before positive case numbers would reflect changes within the community.

Orange County’s water reclamation facilities serve approximately 870,000 people. Although sampling results will
fluctuate as infected individuals go in and out of the virus shedding cycle, the results provide an early
warning of total infections in the areas served by the water reclamation facilities.
