By United States, Ann Azadpour-keeley, Barton R. Faulkner and Jin-song Chen


intended to be brief, state-of-science documents focused on a technical issue of expressed interest and prepared in a concise and readable format. The purpose of this Issue Paper is to discuss some of the conditions under which viral contaminants may survive and be transported in the subsurface, identify sources as well as indicators of viral contamination, outline the effects of hydrogeologic settings on viral movement, and introduce the reader to the current state of virus transport modeling along with an example of modeling applications. The 1986 Safe Drinking Water Act (SDWA) amendments directed EPA to develop national requirements for drinking water disinfection. The legislation required every public water supply system to disinfect unless it fulfills criteria assuring equivalent protection (Macler, 1996).
