A study was undertaken to critically review available information on the survival and transport of pathogens from municipal wastewater sludges applied to land. Most available data are restricted to Salmonella and indicator bacteria. In general, Salmonella showed a 90% (T90) reduction within 3 weeks in sludge-amended soils. In warm climates, inactivation of viruses near the surface was quite rapid with a median T90 of 3 days, while comparable inactivation at low temperatures required approximately 30 days. Maximal parasite survival, as represented by Ascaris, was relatively long with a median T90 of 77 days. Under field conditions including exposure to natural rainfall, virtually no viruses have been detected in soil-water percolates. Available literature strongly favors the contention that parasitic ova are retained at the point of sludge introduction to the soil. Finally, insufficient data are available to provide the various factors required to adequately model pathogen survival and transport in sludge-amended soils.
