CHICAGO — Much has been written about how to minimize the risk of Legionella in cooling towers, but how do you minimize the risk of the potentially deadly bacteria in building water systems, such as hotel spas and drinking water?
A forum at the American Society of Heating, Refrigerating and Air-Conditioning Engineers Inc. (ASHRAE) Winter Meeting examined the topic, along with the use of “Guideline 12-2000: Minimizing the Risk of Legionellosis Associated with Building Water Systems.” The Technical Committee for Water Treatment wanted to know how people are using the guideline — or whether they are using it at all.
