Full Description

In the post-9/11 environment, the anthrax attacks of 18 September 2001 re-energizedseveral aspects of water security research. In the private sector, there was a resurgence ofinterest in transportable water treatment devices and in developing sensor technology toidentify contaminants in water. Government scientists and engineers became interestedin improving the current understanding of fate and transport of contaminants in waterdistribution systems and in developing water treatment and cleanup technology that didnot generate hazardous waste. The U.S. Environmental Protection Agency (USEPA), ECBC, and ERDC stakeholders concluded that the pre-existing fate andtransport models should be updated to include results from meso-scale testing. TheWater Security Research Test Loop (WSRTL) is designed to help update these modelswith meso-scale testing of fate and transport of chemical and biological (CB) agents. The WSRTL would alsoserve as a test-bed to facilitate new generations of sensor technology and water treatmenttechnology.This paper presents basic discussions about likely attack scenarios, remaining problems withcurrent models of fate and transport of contaminants in a distribution system, and areas ofcurrent research. Includes 14 references, figures.
