The Centers for Disease Control and Prevention Releases the 2018 Model Aquatic Health Code

Recommendations in the Model Aquatic Health Code can help reduce risk for disease outbreaks, chemical injuries, and drownings at public aquatic venues

The Council for the Model Aquatic Health Code (CMAHC) announced today that the Centers for Disease Control and Prevention (CDC) has released the 2018 Model Aquatic Health Code (MAHC). This third edition of the MAHC includes important updates that cover emerging public health topics, such as Legionella decontamination and the design and operation of floatation tanks, and continuing challenges like noise reduction in indoor swimming pools.  

The MAHC is a voluntary guidance document that brings together the latest knowledge based on science and best practices to help state and local government officials develop and update pool codes. The guidance is all-inclusive and covers design, construction, operation, and management of public aquatic facilities. If followed, the guidelines in the MAHC can help reduce risk for disease outbreaks, chemical injuries, and drownings. CDC will release a new edition of the MAHC every three years moving forward.

"The CMAHC is committed to strengthening the MAHC based on science and best practices and promoting its use nationwide to protect the health and safety of swimmers, families, and workers at public swimming facilities,” said Doug Sackett, Executive Director of the CMAHC. "We were pleased to learn the 2018 edition of the MAHC incorporates 115 change requests submitted to CDC by the CMAHC.”

What's new?

The 2018 MAHC includes structural changes, clarifying edits, and new or revised recommendations in the areas of disinfection and water quality; lifeguarding and bather supervision; and risk management and safety. A summary of key changes and a track changes version with line-by-line edits is available on the MAHC website.

About the CMAHC

The Council for the Model Aquatic Health Code (CMAHC) was created to manage updates to, and promote voluntary adoption of, CDC’s Model Aquatic Health Code (MAHC), the only all-inclusive national model pool code. The MAHC is kept sustainable, current, and complete because the people who use it also research, develop, discuss, and vote on proposed changes through membership in the CMAHC. The CMAHC submits these proposed changes to CDC as advice on how the MAHC needs to change to keep up with the latest science and best practices. Throughout the year, CMAHC staff educate local and state authorities, aquatic facility owners and operators, designers and builders, manufacturers, and suppliers about the MAHC and its potential to ensure a healthy and safe swimming experience for everyone. Learn more at
