Decontamination of Bacillus Spores from Drinking Water Infrastructure with Physical Removal (Pigging)

Source: U.S. Environmental Protection Agency, Office of Research and Development, National Homeland Security Research Center (NHSRC). Published: 4/2018. This 38-page report summarizes the results of biological decontamination experiments performed at the Water Security Test Bed (WSTB) that focused on removing Bacillus globigii spores adhered to the inner surface of an eight-inch water pipe. Decontamination was undertaken with a technique known as pigging, or physical scouring of the inner pipe surface, followed by disinfection with free chlorine. B. globigii spores are a non-pathogenic surrogate for B. anthracis, which is the causative agent of anthrax. (PDF)
