How Can States and Localities Use the MAHC?

States and localities can use the MAHC to make swimming and other water activities healthier and safer. The MAHC is a free, science-based resource to improve health and safety in

  • 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, and injuries from pool chemicals.

How Was the MAHC Developed?

The MAHC was developed through a collaborative effort involving academia, public health, and industry. The input from the Centers for Disease Control and Prevention has drawn 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 the development of the MAHC, helping manage the MAHC’s various 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 is helping to develop recommendations and tools to make it easier for environmental health professionals at local, state, tribal and territorial levels to use and customize the MAHC.
