If you live in the city of Swartz Creek or Gaines and Clayton Townships, you are under a boil water advisory. A water main break Monday night is the cause of this precautionary advisory. 

The break in the water main caused pressure to drop in the system and may have allowed bacteria to get into the line. If you are going to use water from your tap, it's recommended that you boil it for at least one minute. That will kill any bacteria and make the water safe for everyday tasks.

The risk of contamination is low but the advisory is in effect as a precaution.
