What is the survival time of coronaviruses in water and wastewater?

A study done by Gundy et al. (2009) over the survival of coronaviruses in water and wastewater showed that inactivation of coronaviruses in the test water was highly dependent on water temperature. 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 23øC (10 days) than in water at 4øC (>100 days). Coronaviruses die off rapidly in wastewater, with T99.9 values of between 2 and 4 days. Poliovirus (virus is released through the feces of infected persons) survived longer than coronaviruses in all test waters, except the 4øC tap water.
