Evaluation of sampling strategies for upstream sampling for SARS-CoV-2 RNA

Albert Wilhelm König1, Sarah Ariano2, Darko Joksimovic2

1Graz University of Technology, Austria; 2Ryerson University, Toronto, Canada

An engine for water quality simulations of pulse loads in sewer systems was developed

The engine was used to generate synthetic water quality data of SARS-CoV-2 RNA in order to evaluate sampling strategies regarding their suitability for upstream sewer sampling

The evaluation included consistency of the results, their correlation with the number of infected in the catchment and representation of the catchment

11:10am - 11:30am

SARS-CoV 2 adsorption and desorption capacity of passive samplers for wastewater surveillance

SARS-CoV-2, the virus responsible for the COVID-19 pandemic, has been found in infected symptomatic and asymptomatic patients’ secretions and showed that human wastewater monitoring has the potential to act as a sensitive surveillance system. Passive samplers have shown to be an effective technique for wastewater surveillance however more needs to be known about their adsorption and desorption kinetics. This study showed that electronegative cellulose nitrate membrane followed a linear adsorption relationship and had a slow desorption for up to 7 days since first exposed to the virus. More work is needed to understand the factors influencing these relationships.

11:30am - 11:50am

Developing an open-source, relational data model for recording SARS- CoV-2 signals across multiple sewersheds

The SARS-CoV-2 pandemic has created a demand for simple and cost-effective ways to monitor the health of populations. Wastewater-based epidemiology (WBE) is a monitoring approach that has gained wide acceptance in recent years. However, the complexity of the wastewater system makes the interpretation of the collected data particularly difficult. The PHES-ODM data model was designed to record and organize all variables of interest for a public health measurement campaign to support data exploration and interpretation. The case of Québec province SARS-CoV-2 surveillance is used to demonstrate how this model can be used to create a structured, reusable data pipeline.
