The Model Aquatic Health Code (MAHC) led by the Center for Disease Control and Prevention (CDC) is a voluntary guidance document based on science and best practices that can help local and state authorities and the aquatics sector make swimming and other water activities healthier and safer. States and localities can use the MAHC to create or update existing pool codes to reduce risk for outbreaks, drowning, and pool-chemical injuries. The MAHC guidelines are all-inclusive and address the design, construction, operation, maintenance, policies, and management cutting edge needs of today’s public aquatic facilities. Specific public health issues addressed in the MAHC are often spread across multiple chapters. Mini-MAHCs are intended to make the MAHC more accessible by aggregating the code and annex language on a specific public health issue into more concise documents. This will help environmental health practitioners and operators of public treated aquatic venues quickly find relevant MAHC guidelines and rationale to address specific public health issues and improve patron and staff health and safety. All mini-MAHCs reference content from the 2018 MAHC (3rd Edition).

You can also compare your pool code and practices to those the MAHC recommends to reduce risk of drowning, outbreaks, and pool chemical injuries in your jurisdiction or facility.
