Testing wastewater for RNA strands of the coronavirus might tell local officials how widespread COVID-19 is in their community and whether infections are rising or falling. Known as “sewer survelliance” or “wastewater epidemiology” – wastewater professionals are once again working to protect public health.

An important note – finding coronavirus RNA in wastewater does not mean it is infectious virus. According to WEF, the scientific community has found no evidence of viable COVID-19 virus in wastewater systems.

According to the LA Times:

From Stanford to the University of Arizona, from Australia to Paris, teams of researchers have been ramping up wastewater analyses to track the spread of SARS-CoV-2, the virus that causes COVID-19. Initial studies show that sewage monitoring, or “wastewater-based-epidemiology,” could not only tell us how much the virus might actually be spreading in a community — but also when the virus has finally gone away.

Here’s what the NY Times had to say about wastewater epidemiology:

Now some scientists are looking for the virus not in our blood or spit, but somewhere else: in our sewers.

“It’s the signature of a whole community,” said Krista Wigginton, an environmental engineer at the University of Michigan who has been finding the coronavirus in wastewater around the Bay Area in California.
