About Us

CMAHC promotes health and safety for public swimming facilities in the U.S. A member-driven organization, CMAHC is unique as it exists exclusively to advocate, evolve, innovate, promote implementation, organize research in support of, and advise the Centers for Disease Control and Prevention (CDC) on needed updates to the Model Aquatic Health Code (MAHC).

The Model Aquatic Health Code

Through science-based guidance from the CDC, the MAHC is the only all-inclusive national pool code that addresses current aquatic issues. The MAHC is a voluntary resource guide that can help local and state authorities and the aquatics sector make swimming and other water activities healthier and safer. States and localities can use the MAHC to create or update existing pool codes to reduce risk for outbreaks, drowning, and pool-chemical injuries. The MAHC guidelines are all-inclusive and address the design, construction, operation, maintenance, policies, and management cutting-edge needs of today’s public aquatic facilities.

  • Update Process

    The CMAHC collects, assesses, and relays MAHC Change Request recommendations to CDC every three years via its triennial Vote on the Code conference, during which members gather, assess, and decide on proposed Change Requests to the MAHC.

  • Adoption

    The MAHC is a voluntarily guidance document that can be adopted wholly or in-part, and is driven by your expertise. It is free and accessible to all.
