"Wastewater surveillance for COVID-19" This isn't about drinking water this is about wastewater.
I've been saying this for 2 years. The masks are pointless because covid is spread out your farts NOT your mouth. People laugh at this because it's coming out your ass and not your mouth. Thereby ignoring the primary message.
The reason their surveillance waste water is because before you get any symptoms of being sick you can detect a bacterial increase in the farts and your waste
