Human virus contamination from sprayed wastewater

Domestic wastewaters are used to irrigate soils, thus saving pristine waters. However wastewater contains human enteric viruses that may contaminate the atmosphere after wastewater spraying. Scientists Girardin et al. found that 11-89% of murine mengoviruses applied to the soil were aerosolized during the first half hour. They have developed a model to help policymakers refine standards governing wastewater reuse in irrigation.
