Practice Your Water Response

On this page:
  • Participate in a tabletop exercise
  • Learn about Analytical Preparedness Full-Scale Exercises

Tabletop Exercise Webcasts

Each tabletop exercise (TTX) is led by a facilitator who presents background information on the mock contamination incident.  Participants work together to respond to the scenario by drawing upon real-life experiences as well as knowledge of the WLA Response Plan and other tools.

If you are interested in participating in future TTX webcasts, contact us at WLA@epa.gov.


Analytical Preparedness Full-Scale Exercises

Analytical Preparedness Full-Scale Exercises (AP-FSEs) practice realistic response to a contamination incident. AP-FSEs can involve a wide range of participants, including:

  • EPA regional, state environmental and public health, county, utility, and commercial laboratories
  • Emergency response personnel
  • Federal agencies such as the Centers for Disease Control and Prevention (CDC) and the Federal Bureau of Investigation (FBI)

Scenarios in the past have included chemical warfare agents, toxic industrial chemicals, pesticides, and biological select agents.

If you are interested in participating in future AP-FSE exercises, contact us at WLA@epa.gov.

In larger FSEs, EPA Regional Laboratories coordinate a multi-regional response which can include up to 50 laboratories and over 7,000 samples. In addition to large, multi-regional exercises, EPA conducts local AP-FSEs with individual water utilities.
