This high-level course will discuss the disinfection of recreational water within the Model Aquatic Health Code (MAHC). Attendees will not only learn how to follow the recommendations in the code, but the background behind the recommendations and how they impact prevention of recreational water illnesses (RWIs). Become familiar with the pathogens responsible for disease outbreaks and how to combat them. Water chemistry and disinfection recommendations in the 2016 version of the MAHC will be discussed, as will up and coming potential changes to the 2018 version of the code. Learn about how these changes could impact your waterpark and how you can participate in the development of the code.
