The Survival of Human Enteric Viruses in Holding Ponds.

Abstract

Experimental data obtained from field models since 1975 have shown that virus removal in holding ponds involves two components: inactivation and sedimentation. Several factors may be cited as contributing to viral inactivation. Undoubtedly, higher temperatures can lead to a more rapid inactivation of poliovirus. Such a primary effect is seen in both laboratory controls and in the differences between winter and spring field results. A secondary influence of temperature and sunlight, however, is monitored in terms of increased biological activity. While the cumulative effects of various microbiotic communities are difficult to dissect under field conditions, general biological activity is seen as antagonistic to viral populations. Another important field observation was the appearance of poliovirus in the sediments generated during the life of the model holding ponds. Initial detection of infectious viruses in sediments during the winter run led to a more detailed sediment monitoring system for the spring tests.
