What is a boil water notice?

A boil water notice is a public statement advising customers to boil their tap water before using it, typically in response to an event that has (or could have) introduced contaminants into the water distribution system.

A boil water notice means tap water should not be used for drinking, cooking, or ice-making until tests verify the water is safe. Tests typically take 48 hours. In the meantime, any tap water used for drinking or in anything that humans and animals ingest, should be vigorously boiled for at least one full minute.

Once the public water system has taken the necessary corrective actions to restore the quality of the water distributed by this public water system used for drinking water or human consumption purposes and has provided TCEQ with laboratory results, a rescind notice will be issued to alert the customer that the water no longer requires boiling prior to use.
