Disinfection time hinges on the CT concept: the product of how much chlorine is available (the residual) and how long the water stays in contact with it. When stabilized chlorine is used, the stabilizer (such as cyanuric acid) ties up some of the chlorine, slowing down the disinfection reaction. That means you must give the disinfectant more time to achieve the same level of microbial inactivation. In a diarrhea scenario, the challenge is even greater due to higher microbial load and organic matter that can interfere with chlorine’s action, so a longer contact time is required to reach a safe level of disinfection. Among the options, the longest duration best reflects the extended time needed under stabilized chlorine conditions to reliably inactivate diarrheal pathogens. Shorter times would not provide sufficient disinfection under these circumstances.
