Creates new provisions regarding the discharge of foam fire suppressants

HB 1925 bans the manufacture, sale, and use of firefighting foam containing intentionally added PFAS chemicals (known as "forever chemicals") in Missouri after January 1, 2028, with limited exceptions for airport use required by federal law or military defense applications. It requires immediate reporting of any foam discharge to the state environmental agency within 24 hours and mandates manufacturers to recall existing PFAS-containing foam while reimbursing buyers. The law aims to protect Missouri's water sources by regulating PFAS in firefighting foam, requiring manufacturers to provide certification of compliance. It directly affects foam manufacturers, fire departments, airports, and military facilities handling such foam.
