The 2018 Camp Fire in Northern California was one of the deadliest and most destructive wildfires in U.S. history. Beyond the immediate devastation, the fire brought long-term challenges, including severe water contamination that impacted affected communities for years to come. This session will explore the lessons learned from communicating water safety risks and contamination data in the fire’s aftermath. Attendees will hear from experts who managed the crisis response and communications, learning about the strategies used to address residents’ concerns, balance transparency with reassurance, and maintain public trust. Presenters will discuss the importance of tailored messaging, the challenges of conveying complex scientific data, and the ways community input shaped communication strategies. Participants will leave with insights on best practices for communicating environmental health risks effectively, especially in communities recovering from traumatic events.
