Emergency Preparedness

Being prepared to respond to threats and incidents is not just a plan.

Safety & Security

As there are numerous safety considerations there is no comprehensive list for all public water systems. The Safety and Health Bureau should be consulted in Montana if an assessment is needed to determine safety hazards and requirements.


The American Water Works Association has tools, provides standards, and has links to additional resources for physical security and cypersecurity planning. Vulnerability Assessments are considered a critical starting point of security planning and overall preparedness.

DEQ does not currently send out cybersecurity updates. Please consider subscribing to CISA.GOV updates for FREE critical cybersecurity updates.
