|Ground Water Issue, Movement and Longevity of Viruses in the Subsurface (PDF) (25 pp, 1.13 MB) (EPA/540/S-03/500) April 2003
Because about half of the drinking water supplies in this country come from underground sources and about half of the waterborne diseases are attributed to contaminated ground water, with viruses being the principal pathogens, the transport and survival of particles in the subsurface is an important public health issue.
This issue paper:
The transport, as well as survival, of pathogens in the subsurface are strongly virus dependent and subject to their retention to soil and aquifer materials. The more important factors affecting virus transport are soil water content, temperature, sorption and desorption, pH, salt content, type of virus, and hydraulic stresses.
