Advisories and Notifications

Find boil water notices and water quality advisories

Do not use notice

A Do Not Use notice is issued when there is an imminent risk that the drinking water will cause illness even if the water is boiled. We recommend not using the water for any purposes except:

  • Flushing toilets

Boil water notice 

A boil water notice is issued when a health risk is determined in the drinking water source. We recommend boiling the water for a minimum of 1 minute when used for: 

  • Drinking 
  • Cooking (if not boiled) 
  • Brushing teeth 
  • Washing dishes 
  • Washing fruits & vegetables to be eaten raw 

Other treatment options: 

  • Add two drops of household bleach per one litre warm water (double dose for cold water), shake, and allow to stand for 30 minutes before using. 
  • Add chlorine or iodine tablets and follow manufacturer's instructions.

Water quality advisory 

A water quality advisory indicates a level of risk associated with consuming the drinking water, but the conditions do not warrant a boil water notice or do-not-use water notice.

Water quality advisory may be issued when certain chemicals, such as arsenic, are detected in the drinking water at a level that could pose a long term health risk. The advisory will describe the nature of the risk and what actions a consumer can take to reduce the risk.
