The rates of inactivation of poliovirus 1, echovirus 7, coxsackievirus B3, and simian rotavirus SA11 were compared in polluted and nonpolluted fresh and estuarine water samples. The study was done in two parts, comparing virus survival in samples taken 1 year apart from the same sites. The survival studies were performed at 20°C and at the natural pH of the water samples. In the first part of the study, the time required for a 3-log10 reduction in the initial virus titers was 2 to 3 days in the estuarine water samples and varied from 3 to >14 days in the freshwater samples. In the second part of the study, no clear distinction was found between survival of viruses in freshwater samples and survival in estuarine water samples. The time required for a 3-log10 reduction in the initial virus titers in the second part of the study varied from 12 to >14 days. This indicates that there is a nonseasonal change in factors in the water which affect virus survival. In this study SA11 survival time (used as a model for human virus) was well within the range exhibited by the enteroviruses, indicating that it also is environmentally stable in natural waters.
