The second edition of the Model Aquatic Health Code has been released, marking changes from minor to substantial, and raising at least one major question that will be explored for the next revision.
This marks the first revision of the landmark federal model code for commercial aquatics facilities. For this code, a committee called the Council for the Model Aquatic Health Code (CMAHC) generates and evaluates dozens of change requests and determines which ones it will recommend to the Centers for Disease Control and Prevention, the agency charged with writing and administering the language. The CDC then chooses which change requests it approves and changes the code based on that. (While the MAHC is federally based, it is a model code, meaning it does not take effect unless a state or municipal entity chooses to adopt it.)
