Wastewater-based epidemiology is an internationally recognised cost-effective tool to monitor population exposure to chemicals and infectious diseases, including COVID-19. However, in-sewer degradation of critical biomarkers can limit their wastewater-based epidemiology suitability. This project aims to systematically evaluate the stability of a new suite of potential biomarkers and conduct the first Australia-wide assessment on the impact of biomarker stability on wastewater-based epidemiology estimates using wastewater samples from approximately 65% of the Australian population. The project expects to generate knowledge to expand the application of wastewater-based epidemiology to reliably quantify exposure and status of well-being, even in remote areas.
