The U.S. Environmental Protection Agency (EPA) is hosting a webinar to help community water systems (CWS) learn how to address contamination incidents in their risk and resilience assessments (RRAs) and emergency response plans (ERPs).

America's Water Infrastructure Act (AWIA) section 2013 revised Safe Drinking Water Act (SDWA) section 1433 and requires CWSs serving more than 3,300 people to prepare (or revise) and certify RRAs and ERPs to EPA by specified deadlines every five years. Five-year recertification deadlines are upon us, with deadlines occurring throughout 2025 and 2026. Intentional contamination is one type of malevolent act that CWSs may want to address in their RRA and ERP. In this webinar, EPA will provide examples of how CWSs can address contamination incidents in their RRA and ERP.
