Abstract:

A number of municipalities are contemplating land disposal of primary and secondary-treated sewage in an attempt to reduce stream pollution. Presently operating sewage treatment systems do not completely remove viruses from sludge and effluent, and enteroviruses, reoviruses, and adenoviruses have been recovered from such sewage wastes. Spray-irrigation of vegetables with virus-inoculated sewage sludge and effluent has demonstrated that poliovirus 1 persisted on vegetable surfaces for as long as 36 days, indicating potential contamination of vegetables when spray-irrigation systems are used.
