Hidden within this problem is a principle that is rarely discussed outside of engineering and emergency management circles: water safety is not binary, it is conditional and time-dependent. Treated water does not remain safe indefinitely without controlled conditions. Chlorine residuals decay over time, especially when exposed to heat and organic material. In a stable system, this decay is constantly managed. In a disrupted system, it becomes unpredictable. This means that even stored water, if
