EPA 2026 National Cyber Drill

United States

Join the U.S. Environmental Protection Agency (EPA) for the 2026 National Cybersecurity Drill. This year’s exercise will challenge drinking water and wastewater utilities to operate and maintain critical functions in an environment where telecommunications and internet access are unavailable or unreliable. 

The exercise is built around a simulated scenario in which cyber and/or physical incidents degrade or disable commercial telecommunications infrastructure, internet service providers, and associated systems. As a result, participating organizations must operate in a “disconnected” environment with limited or no access to Supervisory Control and Data Acquisition (SCADA) remote connectivity, cloud-based services, email, Voice over IP (VoIP), and other digital communication tools. This exercise is designed to strengthen sector-wide resilience by testing operations under progressively degraded conditions. It enables participants to identify barriers and dependencies while reinforcing continuity of safe and reliable water and wastewater services in the absence of telecommunications and internet connectivity.  

Continuing Education Units (CEUs) will be provided in most states.
