20-22: Survey of Laboratory and Filed Test Methods of Legionella Cooling Tower Conversion

20-22: Survey of Laboratory and Filed Test Methods of Legionella Cooling Tower ConversionThe Centers for Disease Control (CDC) requires a spread plate culture legionella test during investigations of a known or suspected outbreak of Legionellosis. While owners of cooling towers are concerned about managing their legal liability, they also must manage their operating risks. The culture method is a poor fit for routine assessment of operating risk of Legionella in cooling water systems because operators cannot make timely decisions about
