Abstract		The purpose of the research was to study the infiltration and migration of healthhazardous human viruses, such as enteroviruses, in the unsaturated zone of fractured and karstitied rock, since these rocks present important aquifers in Slovenia. As a possible model for behavior of health-hazardous viruses, we used the salmonella bacteriophage P22H5. After injection, bacteriophages remain in the fractures (channels) and microfracture systems of the unsaturated zone and are rinsed by subsequent larger precipitation events even up to several months after the injection. The field experiments have shown different flow patterns depending on the fractured rock strurcture. In the research area some fast conduits (large fractures or faults) exist where water urns faster than in the total conductive part of the rock. On the other hand the tracer delay in microfracture system areas was observed.
