The boil order was lifted on Friday

ST CHARLES, Mo. — A precautionary boil order issued for parts of St. Charles on Tuesday was lifted on Friday.

The boil order was put in place due to a water main break that has affected pressure within the water system, according to city officials.

On Wednesday, the boil order was expanded to include houses that face Elm Street from Old Elm Street to Elmhurst Drive. Edgewood Drive is also included in the boil order.

The boil order for the area north of Route 370 has been lifted.

On Thursday, the boil order was lifted for homes on Shelburne Court.

Anyone who is affected by a boil order should follow these steps:

Tap water that comes into contact with or is consumed by humans or animals, such as for drinking and cooking, should be brought to a full boil for a minimum of three minutes, then cooled before use.

Throw away beverages and ice cubes if made with tap water.

Keep boiled water in the refrigerator for drinking.

Do not use home filtering devices in place of boiling water. Most home water filters will not provide adequate protection from microorganisms.

Use only boiled water to treat minor injuries.
