Human Coronaviruses: Insights into Environmental Resistance and Its Influence on the Development of New Antiseptic Strategies

This paper does not discuss the presence or fate of coronaviruses in water, but it includes useful insights on disinfecting agents. Some of these (most notably sodium hypochlorite) have relevance for drinking water and wastewater management. But many of them have relevance to the water industry in that these disinfectants may have important roles for managing the disinfection of surfaces at workplaces including water and wastewater treatment plants, laboratories and offices.

A key insight is that sodium hypochlorite solution is effective for achieving more than 3 log10 reduction (>99.9%) of human-infective coronavirus (HCoV 229E) when used as a 0.1 % (1 g/L) solution with a contact time of 1 min.
