The infographic titled “How the Wastewater Surveillance Puzzle Pieces Fit Together in the US” by WEF shows how the different stakeholders in the U.S. wastewater surveillance system work together to collect, test, and analyze wastewater samples for SARS-CoV-2, the virus that causes COVID-19.

The wastewater surveillance system is made up of the following stakeholders:

Public health departments: These departments are responsible for collecting and testing wastewater samples, and for using the data to inform public health decisions.
Wastewater utilities: These utilities collect and transport wastewater samples to public health laboratories for testing.
Academic laboratories: Some academic laboratories also test wastewater samples for SARS-CoV-2.
Commercial laboratories: Some commercial laboratories also test wastewater samples for SARS-CoV-2.
Centers of Excellence: These centers provide training, consultation, and research support to the wastewater surveillance system.
The Centers for Disease Control and Prevention (CDC): The CDC funds the wastewater surveillance system and provides overall strategic guidance.
The diagram shows how these stakeholders work together to collect, test, and analyze wastewater samples. Wastewater utilities collect samples and send them to public health laboratories or commercial laboratories for testing. The laboratories test the samples for SARS-CoV-2 and send the data to the CDC. The CDC then analyzes the data and provides it to public health departments, who use it to inform public health decisions.
