Following the 2001 Anthrax attacks, bioWALL provided 100% cleanup of all impacted locations.
The federal government and private parties recruited bioWALL to remediate all of the structures affected
by the 2001 anthrax attacks. The structures ranged in size and complexity, up to the 17-million ft3
Brentwood postal facility. Many of the structures were highly contaminated and all required complete kill on all
surfaces within, including carpeting, drywall, air ducts, electronics, furniture, and full file archives.
Post-treatment, thousands of wet samples, dry samples and spore strips were tested – the most comprehensive
testing on this scale ever administered – and not a single active spore remained after bioWALL’s treatment.
bioWALL played a leading role in developing this testing program, which is now the gold standard for efficacy
validation and clearance of large structures
