This project evaluated a promising low-tech decontamination alternative to pH amended bleach. The alternative decontaminant that was optimized was activated-peroxide. A benefit of a simple activated peroxide solution is that hydrogen peroxide decomposes into water and oxygen, whereas bleach hypochlorite decomposes into chlorate and chloride ions, oxygen, and chlorine. Chlorine off-gassing from bleach can accumulate in a closed room and can be harmful when inhaled. A simple activated peroxide solution with no ingredients other than hydrogen peroxide, buffer and an activator decomposes into water and oxygen and is considerably less corrosive than bleach. This decontamination materials efficacy was evaluated on indoor and outdoor building materials and during an operational assessment.
