When we issue a boil-water advisory, we recommend boiling your tap water for 3 minutes before drinking it or using it to prepare food. We do this when we find bacteria that do not belong in the water during an inspection. Boiling the water kills those bacteria. 

The water should boil for 3 minutes to kill all bacteria. For example, in a kettle or pan. 

Unfortunately, sometimes the tap water is temporarily not clean enough. This can be the result of a problem or maintenance. For example, when a pipe has been open. If so, there is a small chance that dirt has entered the pipe. As a precaution, you will then receive a boil-water advisory.
