Message Mapping

Message mapping is a science-based risk communication tool that enables members of the emergency response and environmental protection communities to quickly and concisely deliver the most pertinent information about an emergency. EPA has produced a new 40-minute video on message mapping, as well as a report that deals specifically with water utility message maps. The video explains how responders and other stakeholders can develop message maps now as part of their strategy for responding to terrorist threats and other disasters in the future.

EPA produced this video and report as part of a larger effort to implement Homeland Security Presidential Directive (HSPD) 8, which concerns preparedness for, response to, and recovery from a major terrorist incident anywhere in the country. This includes maintaining effective communications.

What Is a Message Map?

Message maps are sets of organized statements, or messages, that address likely questions and concerns in an emergency. Each map identifies up to three unique messages that address a specific issue. Each issue may be addressed by several layered message maps. Each message is based on research associated with a specific scenario. A sample message map appears on this page.

Message maps were developed as a specialized tool for communicating effectively in high-stress, high-concern, or emotionally charged situations. A message map provides multiple benefits. It provides a handy reference for spokespersons who must respond to questions on topics requiring timeliness and accuracy. Multiple spokespersons can work from the same message map to ensure the rapid dissemination of consistent and core messages across multiple communication outlets. Message maps provide a unifying framework for disseminating information on various issues and minimizing the chance of the speaker saying something inappropriate or not saying something that should have been said. A printed message map allows spokespersons to check off the talking points as they are covered. This helps to prevent omissions of key facts or misstatements that could provoke misunderstandings, controversy, or outrage.

The message mapping project has two objectives:

  • To help stakeholders develop scientifically sound message maps for possible high-stress situations
  • To train scientists, first responders, public information officers, and others to use message mapping techniques in their communications during such incidents

To achieve these objectives, EPA sponsored a series of workshops involving experts in various disciplines. The first two workshops, held in May 2004 and March 2005, focused on threats to drinking water. Message maps were developed for scenarios affecting drinking water systems—for instance, insertion of a disease agent into the water, damage to the distribution infrastructure, or massive power failure.

More recent workshops addressed message mapping for attacks on arenas, malls, schools, and office buildings, and for area decontamination, response, and recovery.

In addition to the video, the detailed report that provides message maps for six hypothetical scenarios dealing with water infrastructure crisis incidents has recently been issued. The report, Effective Risk and Crisis Communication during Water Security Emergencies: Summary Report of EPA Sponsored Message Mapping Workshops, is based on water utilities workshops held in 2005 and 2006.
