Impact/Purpose:
Water utilities may someday face a situation where a distribution system is biologically contaminated from either a natural disaster, or a terrorist attack. To determine the extent of contamination or the efficacy of decontamination of the system, internal surface samples may need to be taken by sampling exhumed pipe. Sampling internal pipe surfaces that are wet may be challenging due to the porous surfaces present such as corroded iron and cement. Additionally, the presence of corrosion and biofilm in the sample may inhibit the ability to detect the contaminant. This study evaluated two sampling techniques utilities might use to sample exhumed pipe sections. The contaminant chosen was Bacillus atrophaeus subsp. Globigii, a surrogate for Bacillus anthracis
