results.
The USEPA has done a lot of research in the area of response protocols and has made available a
number of useful tools to make response plans. The most important is the manual Response
Protocol Toolbox: Planning for and Responding to Drinking Water Contamination Threats and
Incidents. This manual is available on the EPA website.
The protocol recommends that action be started based on the Incident Command System (ICS).
Under this system, the utility names a Water Utility Emergency Response Manager (WUERM) that
controls of an incident from the start. The USEPA guidance is very detailed and includes copies of
many forms and procedures that could be useful to start a response.

Plant library management

Plant events that occur during normal operation are saved to the plant event library. If the cause of a

To see the plant event library, push Plant Library on the Maintenance screen.
If the monitor is moved to a different location, erase all the plant events from the plant event library.
