Precautionary boil water advisory for portion of S. St. Louis Co & Jefferson County. Click the link for more info.

From Missouri American Water: 

Missouri American Water is issuing a reverse-911 call related to a precautionary boil water advisory for a portion (not the entire municipality) of Fenton, portion of unincorporated St. Louis County and portion of northern Jefferson County. Customers in the affected area are being texted and emailed now, and a reverse-911 call will go out at 7 a.m. 

  •         Missouri American Water has issued a precautionary boil water advisory for a portion of South St. Louis County and Jefferson County. We are asking customers in this area to bring their water to a boil for three minutes before using it for drinking or cooking. Tap water is okay for washing, bathing and other non-consumable uses. We will take water quality samples in the area Saturday. The precautionary boil water advisory will be in effect until those samples confirm that the water remains safe for consumption. Precautionary boil water advisories can last 24-48 hours. We will call customers again when the boil water advisory has been lifted. For more information, please visit our website or social media. We apologize for the inconvenience.
 ·        Customers can visit a new website to enter an address and confirm whether it is within the affected area. The site can be found by visiting the Missouri American Water website at and click on News & Community, then Maps. Then click the on-page image and select Boil Advisory Map. From there, enter an address to search if it is within the affected area. Direct link:
·        A water main break at Bowles Avenue, leading to a low-pressure event caused this advisory.  
·        The area affected includes the portion of South St. Louis County including Fenton and unincorporated St. Louis County roughly bordered by: The St. Louis County-Jefferson County border to the south (though some customers in Jefferson County are affected); the Meramec River to the east and north; and Branch Road & Hillsboro Road to the west.
  •         The advisory affects approximately 10,000 customers. 
  •         Water for these customers will need to be brought to a boil for 3 minutes prior to consumption, until further notice. Tap water is okay for washing, bathing and other non-consumable uses during this period. 
  •         The precautionary boil advisory is required because of regulations regarding water pressure in our system. In this instance, water pressure dropped to a level that requires we issue a precautionary boil advisory. 
  •         Boil advisories typically last 24-48 hours, though we cannot guarantee that timing. 
  •         Water quality tests will be run as soon as the broken main is repaired.
