Viral pollution of shellfish in estuary waters
Increased levels of chlorination accompanied by prolongation of retention time lead to reduction in number of viral isolations made from treated effluents; enterovirus occurs in osysters collected from seawater containing less than 70 Coliform median most probable number/100 ml; reduction of viral pollutants to undetectable levels in oysters by depuration in estuary waters requires 3 to 6 days; depuration efficacy was adversely affected by large numbers of viral pollutants in oysters, by water temperatures falling below 10 C, or both.
