Impact/Purpose:
With an emphasis on decontamination and consequence management, water infrastructure protection, and threat and consequence assessment, the HSRP is working to develop tools and information that will help detect the intentional introduction of chemical or biological contaminants in buildings, water systems, or the outdoor environment; contain these contaminants; decontaminate buildings, water systems or the outdoor environment; and facilitate the treatment and disposal of materials resulting from remediation activities. The purpose of this investigation was to determine the efficacy of three chemical decontaminants for inactivating the causative agent for anthrax, Bacillus anthracis spores, in soil. The decontaminants that were evaluated included chlorine dioxide gas, a liquid biocide (sodium persulfate activated with aqueous hydrogen peroxide), and methyl bromide. The objective of this study was to provide an understanding of the performance (i.e., efficacy) of these decontamination technologies under a range of environmental conditions, thus guiding their use and implementation in Homeland Security applications for hard-to-decontaminate materials such as soil.
