Unlike previous methods of testing wastewater for COVID-19, the cage — which is 3D-printed at Dalhousie — is inexpensive to make, costing around a buck. Although the equipment needed to analyze the wastewater is expensive, most COVID-19 testing labs would already have it. Public Health in Nova Scotia said it does not use wastewater testing to monitor COVID-19. Researcher Emalie Hayes checks the COSCa device outside Howe Hall, a residence at Dalhousie University. "We can cover more people for wastewater testing than ever could be from sort of clinical testing," he said.
