The Department of Health, in partnership with the County’s Department of Public Works, monitors all seven of the county operated wastewater treatment plants in the county for SARS-CoV-2 (COVID-19). People infected with COVID-19 can shed the virus in their feces. It can be detected in community wastewater, or sewage. Wastewater surveillance measures the presence of SARS-CoV2 in people with and without symptoms.

This is another tool we can use to help monitor COVID-19 spread in Anne Arundel County. Wastewater surveillance does not depend on people having access to healthcare, people seeking healthcare when sick, or the availability of COVID-19 testing. Monitoring wastewater can provide an early indicator of spread of COVID-19 in communities.

Wastewater samples are collected twice a week from the treatment plants in the county, which are sent to the CDC for testing as part of their National Wastewater Surveillance System (NWSS)

To monitor our local data, the most recent three data points for each treatment plant in the county are averaged and categorized based on the following:
