I drank the water before I realized there was a Boil Water Advisory. Am I going to get sick?

The Boil Water Advisory has been recommended as a precaution. If you drank the water before hearing of the advisory, your risk of becoming ill is low. However, if you begin to have fever, diarrhea or vomiting you should seek medical attention. Advise your health care practitioner that you have consumed tap water during the Boil Water Advisory.

I have a dishwasher. Is it safe to use during a Boil Water Advisory?

If your dishwasher has a hot/sani-cycle then it can be used, it safely disinfects dishes. If it does not have this setting, after the final cycle, soak dishes for 1 minute in a solution of 30ml (1 oz) of bleach mixed with 13.5 liters (3 gallons) of lukewarm water. Let dishes air dry.

Can my pets drink the water?

Pets should be provided boiled water, or water from an alternate source until the boil water advisory is lifted.

Can I use my coffee maker?

Most residential coffee makers are not capable of maintaining high temperatures for a long enough period of time to make the water safe to drink. Coffee and tea can be made by using water that has been brought to a rolling boil for a period of one minute or bottled water. If using an automatic shut off kettle, make sure the water has boiled for one minute.

Can I use my activated charcoal filter system (i.e. Brita or other brand names) to treat my water during a Boil Water Advisory?

It is recommended that you discard the filter and replace it with a new one once the Boil Water Advisory is over.
