SURVIVAL OF ENTERIC VIRUSES UNDER NATURAL CONDITIONS IN A SUBARCTIC RIVER
The survival of enteric viruses was studied in the vicinity of Fairbanks, Alaska at selected stations along a 317-km section of the Tanana River. This section was located downstream from all known domestic wastewater sources and was effectively sealed by a total ice cover. The mean flow time through...
