The Drinking Water Advisory Communication Toolbox provides information on how to plan for, develop, implement, and evaluate communication activities with the public and stakeholders during drinking water notifications and advisories. The approach presented in this document recognizes the differences in scope, scale, and severity of situations that trigger advisories and notifications—a main break, a hurricane, a drop in pressure, or intentional contamination. These differences affect the types of tools, planning, and communication used by drinking water systems and locality often affects the terminology (e.g., “incidents,” “notices,” “alerts,” “orders,” etc.) used to describe these situations.
This toolbox includes instructions on how to prepare for communication activities before an incident, how to communicate during an incident, templates and tools to use, and recommendations for follow-up actions and assessments after an incident. The purpose of the toolbox is to enable water systems to communicate effectively with partners and the public in order to protect public health.
Remember to use Federal Public Notification language when developing advisories when there are violations of National Primary Drinking Water Regulations under the Safe Drinking Water Act. This information can be found in 40 Code of Federal Regulations Part 141 (subpart Q, appendix B).
Figure 1 shows the process for preparing for, issuing, and following up after a drinking water advisory.

Each toolbox section includes a checklist of steps. Not every step applies in all circumstances. Each section has a set of tools that applies to its content. The tools can be adapted by water systems to fit their needs.
Tools and Templates
This toolbox complements the EPA’s Revised Public Notification Handbook.
Individual states have different names for drinking water advisories depending on the situation. Advisories are frequently called “notices,” “alerts,” and “orders.”
While the original purpose of this toolbox was to focus on communications related to drinking water advisories resulting from microbiological contamination, recent events—including chemical spills and increases in the incidence of harmful algal blooms (HABs)— demonstrated the need to expand the breadth of this document to encompass other timely issues related to drinking water advisories.
To address these needs, this edition contains information regarding chemical contamination, toxin contamination, high rise buildings, and extreme weather events, as well as new fact sheets that provide specific guidance for various types of facilities (e.g., childcare facilities, healthcare facilities). Additional flushing recommendations have also been included and will continue to be updated as more robust guidelines around flushing are developed in the future.
It is our hope that this third edition of the Drinking Water Advisory Communication Toolbox will provide partners and stakeholders with content that addresses current and future needs as they work to effectively communicate with their audiences and protect public health in the event of a drinking water advisory.
This edition contains a number of updates within the text, as well as new pages to address gaps and enhance the usefulness of the toolbox. Below you will find a list of the new pages in this edition, as well as a brief description of each.

Help! We are issuing a water advisory and we need to alert the public now. We’ve done very little/no planning. Where do we start?
The goal: Communicate in a timely manner by maximizing all of the communication channels you have.
- Communicate the essential information to the critical individuals and organizations as soon as possible.
- Reach as much of the population as you can by as many communication channels as possible.
- Focus your resources on reaching the greatest number of people in a timely manner.
- Keep your messaging consistent across all channels.
Step 1: Determine a basic chain of command.
- Who will make the determination of when the water is safe to drink?
- Who will be the key spokesperson?
- How will updates be communicated?
Step 2: Identify critical partners who need to be informed immediately and who will, in turn, contact a number of other stakeholders and members of the public. Ensure that your message remains consistent across partners. These critical partners may include:
- Local Emergency Manager (enlist that person’s immediate support to make the critical phone calls and connections that are listed below)
- Local Health Department
- Regional Hospital Coordination Unit
- Hospital facility managers
- Local elected officials
- Police chief(s)
- Fire chief(s)
- Medical examiner
- Animal control
- Environmental health
- Vulnerable Populations groups
- Assisted living facilities
- Nursing homes
- Dialysis centers
- Refugee centers
- Deaf advocacy groups
- Neighborhood pages (Nextdoor, Neighborhood Civic Associations, etc.)
- Dept of Transportation (they may agree to put announcements on highway message boards)
- IPAWS (phone alert system coordinated by FEMA)
Step 3: Identify core channels that will maximize communication efforts. Ensure consistent messaging across channels:
- County communications staff and possibly a Joint Information Center (JIC) under IMS structure
- Mass media/news
- Social media (cell phone/text/Facebook)
- Wireless Emergency Alert
- CodeRED alert
- Reverse 911

Water systems and state or local agencies issue drinking water advisories when they believe water quality is or may be compromised. Advisories tell individuals, schools, hospitals, businesses, and others about the situation and how to take immediate action, if necessary.
Drinking water advisories and notifications:
- Provide information—A notification may be issued when consumers need to receive important information but do not need to take any action. For example, a water system may issue a notification to inform households about seasonal changes in water taste or when utility work may cause a loss of pressure.
- Encourage preparedness—Advisories may help customers prepare for planned disruption in service or anticipated water quality threats. Advisories may affect a small area, such as during distribution system construction or repair. Advisories also can urge customers to prepare for a large area incident, such as an approaching hurricane. This type of advisory alerts people to watch or listen for more information.
- Recommend action—Advisories may tell customers to take specific actions, such as to boil water or use bottled water. These advisories may be issued as a response to poor water testing results, reports of a waterborne disease outbreak, chemical contamination, or a loss of distribution system integrity.
- Meet public notification requirements—Advisories are required by the Safe Drinking Water Act (SDWA) when specific circumstances exist. The SDWA requires communication with customers when the water system does not comply with a regulation.
Precautionary and Mandatory Advisories
State and federal regulations specify when drinking water advisories are required. In other instances, water systems or the local public health department may issue advisories at their discretion.
Advisories can include information about preparing food, beverages, or ice; dishwashing; and hygiene, such as brushing teeth, bathing, and flushing toilets.
Main Types of Advisories
- Informational—Communicate planned or anticipated changes in water quality or unanticipated loss of service and provide advice on appropriate action.
- Boil Water—Tells customers to boil water before use. This is the most common type of advisory. They may be precautionary if there is a potential threat to the drinking water supply, or they may be mandatory as required by state and federal regulations. Boil water advisories typically are issued because of concern about microbial contamination.
- Do Not Drink—Tells customers to use an alternate source of water. Do Not Drink advisories are typically issued for chemical and toxin contamination when boiling water is not effective for making water safe.
- Do Not Use—Warns customers not to use tap water for any purpose, including bathing. Do Not Use advisories are typically used only in cases of known microbial, chemical, toxin, or radiological contamination when any contact, even with the skin, lungs, or eyes, can be dangerous. Such advisories are rare because of the risks associated with the lack of water for other purposes (e.g., sanitation).
Figure 2 shows the range of situations that might trigger a drinking water advisory and the type of advisory that would be issued in each situation.
Figure 2. Range of Situations for Drinking Water Advisories
Note: These are examples of potential reasons to issue an advisory; this is not intended to be a comprehensive list. Consult your primacy agency for more information.
1 Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial
growth. Turbidity may indicate the presence of disease causing organisms. These organisms include bacteria, viruses, and
parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
2 Do not drink advisory should be focused on infants below the age of six months consistent with the Public Notification
Standard Health Language (40 Code of Federal Regulations Part 141 (Subpart Q, appendix B).
Because small water systems often have less capacity to implement advisory protocols than larger systems, this toolbox also was designed and tested with small water systems in mind.
Implementing the actions described in this toolbox generally should not require outside support from consultants or others. However, building an effective network by collaborating with other public sector partners, community organizations, and adjacent cities and counties, will help small systems succeed in their efforts.
Suggestions for Small Systems
Identify and prioritize specific tools, templates, or sections from this toolbox to use.
