How to Use the MAHC

The free, science-based 2018 Model Aquatic Health Code (MAHC) (3rd Edition) launched July 18, 2018. State and local government agencies and the aquatics sector can use MAHC guidance to reduce risk for outbreaks, drowning, and pool-chemical injuries at

  • Public swimming pools
  • Pools, hot tubs, and spas in hotels, apartment complexes, and neighborhoods
  • Waterparks
  • Other aquatic facilities

The MAHC guidelines address the design, construction, operation, maintenance, policies, and management of public aquatic facilities. States and localities can use it to create or update existing pool codes to reduce risk for drowning, waterborne illness outbreaks, injuries, and exposures to pool chemicals

Who Developed the MAHC?

The Centers for Disease Control and Prevention led a national collaborative effort with public health, the aquatics sector, and academic partners from across the United States to develop the MAHC. CDC input draws from expertise in the areas of environmental health, infectious disease, public health law, and injury prevention.

Environmental Health Services has been involved in this effort since the beginning, contributing subject-matter expertise to development of the MAHC, helping manage the MAHC’s technical and steering committees, and working with code-making organizations to align pool-related codes with key public health principles. In addition, Environmental Health Services helps develop tools to make it easier for environmental health professionals at local, state, tribal and territorial levels to use and customize the MAHC.
