What to do if a Boil Water Advisory is announced
When a Boil Water Advisory is in effect, all water used for human consumption must be brought to a rolling boil for one (1) minute.
Ontario Clean Water Agency (OCWA) will carry out the required sampling of water for testing in Thunder Bay. The Thunder Bay District Health Unit will advise the Municipality when results allow for the lifting of the Boil Water Advisory.
