A boil water advisory has been issued for Chateauguay and several surrounding areas, local authorities announced on June 13, 2026. The advisory, which affects residents in parts of the Montérégie region, urges people to boil tap water for at least one minute before using it for drinking, cooking, brushing teeth, or preparing food.
Reason for the Advisory
According to officials, the advisory was prompted by a loss of pressure in the water distribution system, which could allow contaminants to enter the pipes. The affected areas include Chateauguay and some neighboring municipalities. Crews are working to identify the cause and restore normal water pressure.
What Residents Should Do
Residents are advised to bring water to a rolling boil for one minute and let it cool before use. Alternatively, bottled water can be used. The advisory applies to all households, businesses, and institutions in the designated zones. Officials recommend discarding any ice cubes or drinks made with tap water since the advisory took effect.
Boiled or bottled water should also be used for washing fruits and vegetables, making baby formula, and cleaning dishes. However, tap water is safe for showering and bathing, as long as it is not swallowed.
Expected Duration
The advisory will remain in effect until water samples confirm the system is safe. Authorities will issue updates as testing results become available. Residents are encouraged to monitor local news and official municipal channels for further information.
This is a developing story. More details will be provided as they emerge.
