The survival and transport patterns of poliovirus 1 and echovirus 1 were studied in undisturbed soil cores which were treated with digested sludge and exposed to natural weather conditions prevailing in north central Florida. It was shown that, under those experimental conditions, enteroviruses are relatively rapidly inactivated in the soil. A more rapid virus decline was observed during the warm and dry fall season than during the warm and wet summer season. The monitoring of soil core leachates has shown that both viruses were effectively retained by the sludge-treated soil.
