Centers for Disease Control and Prevention (CDC) sent this bulletin on 1/24/2014

Model Aquatic Health Code

Thank you for your interest in the Model Aquatic Health Code (MAHC), a collaborative effort of public health, academia, and industry working to protect individuals, families, and communities from preventable waterborne diseases and injuries through evidence-based guidance. Read below for the latest information.


The Disinfection and Water Quality Module and the Regulatory Module have been revised and re-posted after the first public comment period. View the revised modules and the response to comments documents.


The first full version of the MAHC is coming soon, and we want your feedback! We plan to release the first full version of the MAHC—a combination of all revised modules and supplemental information—in spring 2014 for a 60-day public comment period.

Get a head start!

Because the MAHC will be a long document, we encourage you to get a head start and begin compiling your comments now on the modules that have been revised after the first public comment period so that you have plenty of time to submit your feedback. The content of these modules will not change substantially, but we will have to reorganize information that may be duplicated in multiple modules and resolve conflicts where duplicate items make different recommendations. We will announce when the full version is posted and we are accepting public comments for 60 days.

Each module has a short synopsis or abstract highlighting the most critical recommendations.

You can monitor the status of all modules on the MAHC website.
