Reactivity of Enveloped Virus Genome, Proteins, and Lipids with Free Chlorine and UV254

The current understanding of SARS-CoV-2 is that waterborne transmission is unlikely to be an important mode of infection. While the virus RNA has been reported in untreated sewage (and many more such reports can be anticipated throughout 2020 and beyond), these reports do no imply that viable, infective virus is present. Very few studies haveContinue reading “Reactivity of Enveloped Virus Genome, Proteins, and Lipids with Free Chlorine and UV254”

Evaluation of Phi6 Persistence and Suitability as an Enveloped Virus Surrogate

Understanding the survival and fate of viruses, such as SARS-CoV-2 in water is important to enable us to model and predict exposure risks through contact with wastewater, environmental water systems and drinking water. In particular, it will be necessary to understand how variable factors such as temperature, pH, salinity, organic matter concentration, or other matrixContinue reading “Evaluation of Phi6 Persistence and Suitability as an Enveloped Virus Surrogate”

Survivability, Partitioning, and Recovery of Enveloped Viruses in Untreated Municipal Wastewater

This is a paper from the research team led by Associate Professor Krista Wigginton at the University of Michigan. Wigginton’s team have focused on the fate of enveloped viruses (including coronaviruses) in the urban water cycle (drinking water, sewage, sewage treatment) for much of the last decade. Most researchers studying viruses in water have focusedContinue reading “Survivability, Partitioning, and Recovery of Enveloped Viruses in Untreated Municipal Wastewater”
