WICRD recently published updated versions of its Small System RRA Checklist and ERP Template and plans to publish an updated version of the Vulnerability Self-Assessment Tool (VSAT) by the end of November 2024. A Checklist of Priority Cybersecurity Practices for Water Systems was added to these resources to bolster a CWS’s analysis of their cybersecurity practices. EPA encourages all CWSs to fill out this new cybersecurity checklist and add it to their RRA or ERP.
