Healthy Swimming and Recreational Waters

NEHA is committed to providing education, resources, and support for healthy swimming and recreational water programs around the country.  Here you'll find information about the newest projects and the resources we offer.


The Model Aquatic Health CodeModel 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

Meet the CMAHC 
The Conference for the Model Aquatic Health Code (CMAHC) will serve as a key CDC partner by serving as a national clearinghouse for gathering stakeholder input and advice on needed improvements to the MAHC. Consider joining today.
