The Higgins and Langley Memorial and Education Fund is a non-profit organization that works in swiftwater rescue. They offer support for those that have lost loved ones in drowning and other aquatic accidents. They promote drowning prevention programs, water rescue training for emergency responders, standards for recovery operations that reduce the burden on grieving families, and lobby for change in the way all open and moving water related emergencies are managed.
