The pH of most natural water is between 5–9. Enteric viruses are stable in these conditions. On the other hand, many enteric viruses are more stable at pH 3-5 than at pH 9 and 12. Enteroviruses can survive at pH 11–11.5 and 1–2, but for only short periods.

Epidemiologic evidence must implicate water or volatile compounds from the water that have entered the air as the probable source of the illness.
