Toxic Health Threat Warning Act of 2025

HR 3817, the Toxic Health Threat Warning Act of 2025, requires the Secretary of the Army to test water released from flood control structures for cyanotoxins before any release. If cyanotoxin levels exceed 8 parts per billion, the Secretary must notify the public and local governments about the release and potential health risks. This law directly affects communities and local governments downstream of flood control structures where water is released. The key provision mandates testing and public notification when toxin levels surpass the established threshold, aiming to prevent exposure to harmful cyanotoxins.
