What is a water boil advisory?

A water boil advisory is a public health notice that is issued by Laredo or Texas government when there is a potential risk of bacterial contamination in the water supply. The advisory recommends that residents boil their water before using it for drinking, cooking, or brushing teeth.

The advisory is usually issued in response to a specific event, such as a water main break, flooding, or a loss of water pressure that could allow bacteria to enter the system. Boiling water kills most types of bacteria and parasites that could cause illness, and is therefore recommended as a precautionary measure to prevent the spread of waterborne diseases.

How long will a water boil advisory last?

A water boil advisory can last for a few hours or several days depending on how quickly the cause of the contamination can be identified and remedied. Once the cause of the contamination has been addressed and the water has been tested and determined to be safe, the advisory can be lifted.

In some cases, a water boil advisory may last longer than a few days if the contamination is particularly severe, or if it takes time to implement and verify the effectiveness of the fix. If you have been issued a boil advisory, we recommend you follow the advice of local officials and to monitor local news and updates to determine when it will be lifted.
