MAHC Announcements
All Model Aquatic Health Code Technical Committees have been established. However, those interested in the Model Aquatic Health Code project can still provide input into the process by commenting on the draft model code language that will be posted on this website. We welcome all comments and suggestions. Interested persons may also wish to submit an application form for technical committee membership. We will maintain a list of interested participants, as occasionally a member on a Technical Committee can no longer participate and is replaced with a new member.
Background
In the United States, all pool codes are reviewed and approved by state and/or local public health officials. As a result, there are no uniform national standards governing design, construction, operation, and maintenance of swimming pools and other treated recreational water venues. Thus, the code requirements for preventing and responding to recreational water illnesses can vary significantly among local and state agencies. The Model Aquatic Health Code (MAHC) is intended to transform the typical health department program into a data-driven, knowledge-based, risk reduction effort to prevent disease and injuries and promote healthy recreational water experiences. This MAHC should ensure that the best available standards and practices for protecting public health are available for adoption by state and local agencies. It will provide uniform guidelines for the design, construction, operation, and maintenance of swimming pools and other disinfected swimming venues to prevent recreational water illnesses and promote healthy recreational water experiences. There is no federal regulatory authority for disinfected recreational venues. As a result this Model Aquatic Health Code will serve as a model and guide for local and state agencies needing guidance to update or implement a MAHC in their jurisdiction.
This effort stems from a CDC-sponsored workshop titled "Recreational Water Illness Prevention at Disinfected Swimming Venues" convened on February 15-17, 2005, in Atlanta, Georgia. The workshop assembled persons from different disciplines working in state, local or federal public health agencies and the aquatics industry to discuss ways to minimize the public health risks associated with recreational water illnesses spread through disinfected swimming venues. CDC, through an initial grant from the National Swimming Pool Foundation, is working with public health and industry representatives across the United States to build this effort. Initial efforts will be focused on reducing the spread of recreational water illnesses at treated swimming venues.

The MAHC process involves a Steering Committee guiding the work of many Technical Committees working on specific areas of the MAHC. The linked Project Outline document describes the MAHC vision, organization, goals, and objectives. The MAHC Process Diagram illustrates the sequence of events being undertaken as part of the MAHC process.
