Decontamination of Subway Railcar and Related Materials Contaminated with Bacillus Anthracis Spores via the Fogging of Peracetic Acid and Aqueous Hydrogen Peroxide [open pdf - 4MB]
"The Department of Homeland Security's (DHS's) Underground Transport Restoration (UTR) Program was established to identify potential methods for rapid characterization, cleanup, and clearance of biological contamination in an underground transit system. This would include physical structures (tunnels and stations) and rolling stock (railcars). The UTR Project is expected to improve the capability for transit systems to recover rapidly from a biological release event and thereby addresses a high‐priority need expressed by the Transportation Security Administration (TSA) and local transit systems. As part of this UTR Project, the U.S. Environmental Protection Agency (EPA) is evaluating multiple methodologies for the decontamination of subway and railcar materials contaminated by a biological agent."
