The time required for the virus titer to decrease 99.9% (T99.9) shows that in tap water, coronaviruses are inactivated faster in water at 23 ° C (10days) than in water at 4 ° C (> 100days). Coronaviruses die off rapidly in wastewater, with T99.9 values of between 2 and 4 days.
It's not 100 days it's 392 to 588 days at 4 ° C ...
