Model Aquatic Health Code (MAHC)

Model Aquatic Health Code (MAHC)

The Model Aquatic Health Code (MAHC) is the nation's only all-inclusive model pool code. It is based on scientific data and best practices gathered by public health and aquatics industry experts, and, consequently, more expedient for jurisdictions to justify, adopt, and implement. Unlike legislation, the MAHC is voluntarily adopted, wholly or in part, and driven by expertise. It is free, accessible to all, and backed by the Centers for Disease Control and Prevention (CDC) and other organizations. Read the statements of endorsement here:

National Swimming Pool Foundation (NSPF)
Council of State & Territorial Epidemiologists (CSTE)
National Association of County & City Health Officials (NACCHO)
National Environmental Health Association (NEHA)

The MAHC is updated every two years by the Council for the Model Aquatic Health Code (CMAHC). The CMAHC, a nonprofit organization, was created to support and improve the MAHC by gathering input and advice from industry stakeholders. The MAHC, 1st Edition, was published in July 2014. The CMAHC held its first Biennial Vote on the Code Conference at the October 2015 World Aquatic HealthTM Conference, where members of the CMAHC presented over 150 Change Requests. The members voted on the changes, and the subsequent Vote on the Code resulted in the MAHC, 2nd Edition, published in July 2016. The MAHC, 3rd Edition published in July 2018, implementing changes approved during the 2017 Vote on the Code. To participate in future CMAHC Conferences please visit the Conference for the Model Aquatic Health Code or email Susan Wichmann.

Why Support the MAHC?

Every five or ten years, health departments contact stakeholders and experts to ask for input on the town, city, county, or state code. A group of people meet for many hours over several months to debate everything from depth marking specs, entrapment devices, cyanuric acid levels, circulation rates, water replacement vs. reduced backwashing, chemical feeder rates, to whether operators should be trained. Predecessors are questioned as the new committee members attempt to understand why and how decisions were made in the past. The process repeats itself again, five to ten years later, when the new health official calls a new group together to reassess the code.

It happens so often, it seems normal, but it's certainly inefficient. This is why the industry demands a model, science-based standard that includes all the supporting rationale for the code. This code is a public domain (free) guideline that all jurisdictions and the industry can debate, refine and adopt.

From the expertise of hundreds of volunteers and thousands of commenters, we now have a free, science-based Model Aquatic Health Code. Make it your own, or, make it better and then make it your own. Let's be part of growing the future of aquatics by supporting the expertise and efficiencies represented by a model code.

How to Get Involved

The CMAHC is looking for members and sponsors to help continue to move the MAHC forward and support adoption. Volunteers are also needed to fill vital roles in the proposed submission review and discussion process. Visit cmahc.org to get involved!
