The survival of HAV, poliovirus 1 and F+ coliphages was studied under
various conditions in both fecally soiled disposable diapers and solid
waste landfill leachates. Fecally soiled disposable diapers and leach
ates were seeded with viruses and incubated aerobically and/or anaerob
ically at 5, 25 and 40-degrees-C for 90 days. Under some conditions, v
iruses survived >90 days in fecally soiled diapers and landfill leacha
tes, especially at lower temperatures. In both fecal suspensions and l
eachates at 5-degrees-C, all viruses were inactivated slowly (<1 log10
in 30 days). At 40-degrees-C, viruses were reduced to non-detectable
levels (by >4 log 10) in 8-29 days in diapers and in as little as 2 da
ys in leachates. Some viruses were inactivated at different rates unde
r anaerobic versus aerobic conditions. Under most conditions, persiste
nce of F+ phages, HAV and poliovirus 1 was similar, thus suggesting th
at these phages may be useful enteric virus indicators in solid waste
and leachates.
