Water Safety: Legionella Control Strategies
John Cioffi, NALCO Water, An Ecolab Company
Recent trends have increased public awareness that waterborne pathogens can be associated with water systems and that these water systems must be managed to reduce the risk of a health hazard associated with cooling water and domestic water systems. More specifically, questions around the subject of Legionella are being raised. This presentation will provide an overview of basic Legionella facts, the market events that led to the creation of American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 188, and the move toward the convergence of a “health-based” treatment strategy.
