Over one‐half of the waterborne disease outbreaks in the United States are due to the consumption of contaminated ground water. Although viruses are a major cause of illness in these outbreaks, very little is known about the factors which influence how long viruses can remain infective in ground water. Experiments were conducted using several ground water samples obtained from drinking water wells to determine the effects of the naturally‐occurring bacteria on the survival of coliphage MS‐2 and poliovirus type 1 inoculated into the samples. The numbers of bacteria and viruses were monitored over a 30‐day period. Parallel experiments were conducted using water which had been filtered to remove the bacteria. The increase in bacterial numbers in the first 24 hours of incubation was significantly correlated with the decay rate of coliphage MS‐2. However, consistent trends were found in the ability of the viruses to persist in the presence or absence of bacteria. [ABSTRACT FROM PUBLISHER] |
