A drinking water advisory can occur at any time. Water systems must act quickly when an incident is suspected or identified. The first action must be to assess the situation and follow standard operating procedures (SOPs) for issuing a drinking water advisory.

Tip

Water systems as well as state, local, tribal, and territorial agencies can pull out the Tools and Templates that correspond to the “Before an Incident” and “During an Incident” sections to use as a “Go Kit” in situations where pre-planning activities may have been incomplete. They can be found individually or in a zip file on the Tools and Templates page.

This section contains the essential strategies and activities necessary to create public awareness of a drinking water advisory incident or to issue a Boil Water, Do Not Drink, Do Not Use, or a precautionary advisory for the general public, including susceptible populations who may have communication barriers or medical needs.
