Healthy Swimming and Recreational Waters

The Model Aquatic Health Code


Model Aquatic Health Code (MAHC)

MAHC is a collaborative effort of public health, academia, and industry. By providing a model code based on the latest science, the MAHC strives to keep swimming healthy and protect individuals, families, and communities from preventable waterborne diseases and injuries. The MAHC encourages stakeholder involvement, so please make your swimming pool program aware of the following resources and opportunities to get involved.

First Complete Model Pool Code Now Available! 
On August 29 CDC launched the nation’s first voluntary guidelines based on science and best practices for improving health and safety at swimming pools and other aquatic venues: The Model Aquatic Health Code (MAHC) 1st Edition. States and localities can use the MAHC to create or update existing pool codes to reduce risk for outbreaks, drowning, and pool-chemical injuries. Check out the MAHC code; the annex with scientific explanations; sample forms, and materials including the MAHC fact sheet, infographic, and web button

To learn more about the MAHC, view the 2015 AEC presentation:

Wastewater Treatment Systems
