Greater Sudbury Ends Boil Water Advisory

Public Health Sudbury and Districts (PHSD) has officially lifted the boil water advisory for Greater Sudbury. The advisory was in place for approximately 90,000 residents since May 6, 2023. It was rescinded at 6:59 p.m. on May 8, 2023.
Details of the Advisory
The boil water advisory affected several areas, including:
- New Sudbury
- Sudbury
- Falconbridge
- Parts of Garson
This precautionary measure was initiated after coliform bacteria was detected in routine drinking water samples, indicating a potential contamination risk. Dr. Emily Groot, associate medical officer of health, emphasized the importance of effective public health monitoring during this situation. “Potential concerns were identified early, and a boil water advisory was issued to protect residents,” she stated.
Investigation and Findings
Two consecutive sets of water samples have returned negative results for harmful bacteria. This improvement suggests that the water supply is now safe and that treatment systems are functioning correctly. The cause of the initial contamination remains under investigation, but no immediate concerns have been reported.
“Boil water advisories are crucial for protecting public health, and this incident highlights the need for consistent health monitoring,” a PHSD representative remarked.
Upon the lifting of the advisory, residents are advised to take the following steps:
- Run cold water faucets for five minutes or until the water runs clear.
- For large-volume users, longer running may be necessary.
- Run water softeners through a regeneration cycle.
- Drain and refill hot water heaters set below 45°C.
- Replace water filters used during the advisory.
- Discard the first three batches of ice from refrigerator ice makers.
Guidelines for Food Premises Operators
Operators of food establishments must adhere to specific guidelines as well:
- Flush all water lines by letting faucets and equipment run for at least five minutes.
- Clean and sanitize water-connected equipment, including:
- Ice machines: clean and sanitize bins and lines.
- Beverage dispensers: run machines with hot water for five minutes.
- Run empty machines through a full sanitization cycle before normal use.
- Sanitize all food contact surfaces thoroughly.
PHSD, alongside the City of Greater Sudbury, will continue to assess the situation. They remain committed to ensuring community health and safety. If any new findings arise, the public will be promptly informed.
