Impact/Purpose:
This report describes the work on decontamination of bacillus spores in building water systems done at NIST (Gaithersburg, MD). The focus is on Bacillus anthracis (BA) spores and the use of a simulant species B. thuringiensis (BT). Simulated water systems were developed using either commercial biofilm reactors or pipe section reactors. The adhesion and disinfection of BT and BA spores adhered to the biofilm-conditioned pipe materials by chlorine and monochloramine was measured in under different conditions including low flow and high flow.
