Boil Water Door Hanger – English and Spanish

Use this template to inform your customers of contamination in the system and precautions they can take. Door hangers include information in English and Spanish. You can get door hangers from local health departments, our regional offices, or download the Microsoft Word or PDF template at right.

Ways to use door hangers to inform customers quickly during a public health advisory:

• Write information on each door hanger.
• Fill in the top portion of the door hangers. Then print labels with the water system name, ID#, county, contact person's name and phone number, and the date you distribute the notice. Attach a label to the bottom of each notice.
• Complete the Drinking Water Warning template, make photocopies, and then staple a copy to the door hanger. This will draw attention to the notice.

Coliform Public Notice Certification (form)

You must complete and mail the form to us within 10 days of notifying your customers of an acute MCL violation. You must also send us a copy of the public notice you proved to your customers.

• Announcing Boil Water Advisory: Send at the start of a boil water advisory. Gives advice to customers and explains what you’re doing to resolve the problem.

* Some publications recommend boiling the water for 3 to 5 minutes. We recommend customers bring their drinking water to a rolling boil for one minute.
