The Survival of Human Enteric Viruses in Holding Ponds.

Abstract

The inactivation of Poliovirus I and Coxsackievirus B-3 was studied in model wastewater holding ponds. The ponds are constructed at cast concrete tanks 5 feet in diameter and 18, 30, 42 and 90 inches deep. Experiments were conducted using either settled wastewater (primary effluent) or wastewater that had undergone biological treatment and chlorine disinfection (final effluent). Results indicated that viral inactivation was more rapid during the warmer seasons, and in final effluent. The rate of viral inactivation was enhanced by the development of alkaline pH in holding ponds due to algal metabolism. Approximately 10% of the viruses added to the ponds was detected in the settled solids. The virions in the sediment portion of the ponds underwent inactivation less rapidly than those viruses in the water columns. (Author)
