Crypto. Giardia. Norovirus. Unfortunately for swimmers and pool operators everywhere, rising numbers of recreational waterborne illness from these germs qualify as one of the more unpleasant developments in aquatics in the past 25 years.

But the CDC’s Michael J. Beach hopes to change that. As associate director for healthy water and chief of Atlanta-based CDC's Waterborne Disease Prevention Branch, he’s a scientific resource for the industry and an expert in these emerging recreational waterborne illnesses.

Part of the solution may be found in the Model Aquatic Health Code, which seeks to provide a framework for state and local requirements on disinfection and water quality, as well as other aspects of aquatics facility safety and management. Beach sits on the steering committee for the code, which has been moving through the public comment and review process in various parts since 2008. The complete document is expected to be released in 2013.
