Recognize Avoid Isolate Notify

Use RAIN to prevent exposure, protect public

health, respond and recover from possible and

credible criminal incidents at both drinking

water and wastewater facilities. Because

incidents will vary, use RAIN as a standard

response to minimize the risk to public health

and to promote collaboration with local, state

and federal agencies for an effective and

immediate site evaluation and response.
