COVID-19 Waterblog

This site has been established as a means of collating current scientific information and expert opinion on the presence and fate of SARS-CoV-2 in water and wastewater. As such, it will provide an updated assessment of the possibility of environmental transmission of COVID-19 and ways that such risks can be effectively managed.

Critical Review and Research Needs of Ozone Applications Related to Virus Inactivation: Potential Implications for SARS-CoV-2

Ozone disinfection has demonstrated high efficacy against enveloped and non-enveloped viruses, including viruses similar in morphology to SARS-CoV-2. Due to this efficacy, numerous gaseous and aqueous phase ozone applications have emerged to potentially inhibit virus persistence in aerosols, surfaces, and water. This review identifies the exposure requirements for virus inactivation and important safety considerations forContinue reading “Critical Review and Research Needs of Ozone Applications Related to Virus Inactivation: Potential Implications for SARS-CoV-2”

Passive sampling of viruses for wastewater-based epidemiology: a case-study of SARS-CoV-2

The shedding of pathogens by infected humans enables the use of sewage monitoring to conduct wastewater-based epidemiology (WBE). Although most WBE studies use data from large sewage treatment plants, timely data from smaller catchments is needed for any targeted public health action. Traditional sampling methods, like autosamplers or grab sampling, are not conducive to quickContinue reading “Passive sampling of viruses for wastewater-based epidemiology: a case-study of SARS-CoV-2”

Early-pandemic wastewater surveillance of SARS-CoV-2 in Southern Nevada: Methodology, occurrence, and incidence/prevalence considerations

Numerous wastewater surveillance studies subsequently confirmed detection of SARS-CoV-2 RNA in wastewater and wastewater-associated solids/sludge. However, the methods employed in early studies vary widely so it is unclear whether differences in reported concentrations reflect true differences in epidemiological conditions, or are instead driven by methodological artifacts. This study aimed to compare the performance of virusContinue reading “Early-pandemic wastewater surveillance of SARS-CoV-2 in Southern Nevada: Methodology, occurrence, and incidence/prevalence considerations”
