Source reduction in an anthrax-contaminated mail facility

Area of Science:

• Environmental Science
• Public Health
• Biosecurity

Background:

• The 2001 anthrax attacks necessitated extensive decontamination of affected facilities.
• Source reduction is a crucial preliminary step in large-scale building remediation, involving item removal and surface pretreatment.
• Effective waste disposal strategies are integral to the entire decontamination process.

Purpose of the Study:

• To detail the source reduction and waste disposal activities implemented at the Department of State (DoS) Diplomatic Pouch and Mail Facility (SA-32).
• To document the methods used for decontaminating materials and surfaces within the facility.
• To provide insights into the timeline and costs associated with such remediation efforts.

Main Methods:

• Removal of nearly all materials from the facility prior to vaporized hydrogen peroxide fumigation.
• Categorization of removed materials into essential, nonessential recyclable, and nonessential non-recyclable items.
• Application of five distinct decontamination technologies to removed materials and pretreatment/fumigation of fixed surfaces.
• Implementation of environmental sampling for quality assurance throughout the source reduction phase.

Main Results:

• The source reduction phase at the SA-32 facility lasted approximately 9 months.
• The total cost for the source reduction process was approximately $4.3 million.
• The comprehensive remediation project spanned about 16 months and incurred a total cost of $8.6 million.

Conclusions:

• Source reduction and meticulous waste disposal are vital components of effective bioterrorism response and building decontamination.
• The described methods demonstrate a systematic approach to managing contaminated materials and facilities.
• The SA-32 remediation highlights the significant time and financial investment required for large-scale decontamination operations.
