This powerpoint presentation begins by providing the study objective: to summarize the overall approach for the Bioterrorism RiskAssessment (BTRA) waterborne contamination model used toevaluate the risk associated with the purposeful contaminationof water using biological agents. The BTRA technical approach is presented, along with the BTRA water contamination model, dissemination scenarios, water network distribution assumptions, BTRA water contamination agents, agent decay, ingested infectious/intoxicating dose, and water model consequences. Presentation summary includes the following: themodel is general enough to approximate to a broad range of city watersystems or commercial buildings, and accounts for losses due tochlorinated water systems and mixing in the pipes; and, themodel is only as good as its input and assumptions. Data gaps existand introduce large uncertainties, including:decay kinetics of all agents which can be impacted by numerousfactors including chlorine, biofilms, pipe materials, etc;human ingested infectious/intoxicating doses of some agents; and,decontamination costs. Includes figures.
