U.S. Geological Survey COVID-19 Wastewater Surveillance
USGS, as part of the National Wastewater Surveillance System, designed and implemented high-frequency sampling of wastewater across six states throughout September 2021, to support tracking of potential increases in COVID-19 infections in communities. COVID-19 viral loads were determined for each sample with the goal of delivering results to the CDC within three days of sampling.
