During a boil-water advisory issued by the local authority, what is the safest practice for the operation?

A boil-water advisory means the tap water may be unsafe, so the operation must switch to bottled or treated water for drinking, ice, and food preparation, or cease operations if it cannot operate safely, following the regulatory authority's instructions. Untreated tap water can carry pathogens even when it runs clear and odorless, and an ice machine filter is not a treatment device — freezing does not kill what is in the water. The advisory takes effect when the authority issues it to the public; no individual phone call to the restaurant is coming, and waiting for one means serving unsafe water in the meantime. This may function as an imminent health hazard requiring notification.
