Understanding the Factors that Affect the Detection and Variability of SARS-CoV-2 in Wastewater
Wastewater surveillance of SARS-CoV-2 complements clinical testing as a means to assess COVID-19 trends within a community. This webcast will present the findings of the project, Understanding the Factors that Affect the Detection and Variability of SARS-CoV-2 in Wastewater (5093). Presenters will detail how wastewater sampling designs impact the quantifiable SARS-CoV-2 genome in both centralized and decentralized wastewater collection and treatment systems. This research found that 24-hour composite samples best represent the trends of SARS-CoV-2 concentrations in centralized WWTPs, and primary sludge samples had nearly 10 times higher concentrations of the viral genome. This suggests that sludge testing could provide greater sensitivity for SARS-CoV-2 detection. The decentralized wastewater management system also has the potential to be used as the access point for wastewater surveillance.
