Many lessons were learned from three exercises conducted at the direction of the Washington
State Department of Health, Office of Drinking Water, under a grant from the U.S.
Environmental Protection Agency. The exercises were conducted separately with water
utilities, emergency responders, regulatory agencies, and others in different regions of
Washington State in July 2004. The purpose of these exercises was to provide a learning
environment to acquaint participants with each others' emergency responsibilities and
procedures, and to determine shortfalls and successes in emergency response that are
applicable to water system emergencies in general. Scenarios involved a chemical
contamination event, biological contamination event, and perceived biological
contamination.
Lessons learned from the exercises can be useful in conducting future water system
emergency exercises, and in preparing for real-life emergency response. After three
exercises, the project team recognized particular themes that applied to all the emergency
scenarios. These are:
a need for communication and information exchange between all agencies involved in
water system emergencies;
understanding roles and responsibilities before an emergency will smooth recovery during
an emergency;
water sampling procedures are vital and need to be developed for each water system;
communications with the public can be improved, and water systems must be prepared to
work with the media; and,
conducting a successful exercise and capturing the lessons learned from it may require
particular techniques.
Lessons learned within each theme include issues related to the theme, what went well and
what did not, and possible solutions to address the issues.
