The Model Aquatic Health Code is undergoing its first update, and there's a week left to submit change requests for the 2016 version.

The new organization meant to work with the CDC on developing and maintaining the code, the Conference for the Model Aquatic Health Code has set the deadline for change requests for Feb. 19.

The MAHC, available online, was written by the Centers for Disease Control, is the first pool and spa code produced by the federal government. Released last year, it was developed as a comprehensive code and covers covers 14 subject areas: facility design and construction; recirculation systems and filtration; disinfection and water quality; risk management and safety; facility maintenance and operation; monitoring and testing; contamination burden; hygiene facilities; fecal/vomit/blood contamination response; operator training; lifeguarding and bather supervision; regulatory program administration; ventilation and air quality; and preference/user guide/definitions.

As a model code, it only applies to those areas that formally adopt the language, but some believe it also will influence government entities looking to write their own codes.
