A boil water advisory has been issued for parts of Greater Sudbury, including Sudbury, New Sudbury, and Falconbridge, after adverse water sample results were reported on Wednesday, May 6, 2026. The advisory was announced by public health officials, urging residents in the affected areas to boil their tap water for at least one minute before using it for drinking, cooking, brushing teeth, or any other activity that involves ingestion.
Reason for the Advisory
The advisory was prompted by adverse water sample results that indicated potential contamination. Officials did not specify the exact nature of the contaminants but emphasized that the measure is precautionary to protect public health. The affected areas include a significant portion of the city, and residents are advised to follow the guidelines until further notice.
What Residents Should Do
Residents are instructed to bring water to a rolling boil for one minute and allow it to cool before use. Boiled water or bottled water should be used for drinking, making ice, washing fruits and vegetables, and preparing food and baby formula. The advisory also applies to pets. Tap water may still be used for showering and bathing, but care should be taken to avoid swallowing water.
Duration and Updates
The boil water advisory will remain in effect until water quality tests confirm that the water is safe to drink. Public health officials will provide updates as more information becomes available. Residents are encouraged to monitor local news and official channels for the latest information.
This advisory comes as the city continues to address infrastructure challenges and ensure safe drinking water for all residents. Similar advisories have been issued in the past due to system maintenance or unexpected contamination events.
