18-18: Legionella Litigation: How Cases are Won and Lost at the Microbial Level Legionnaires' Disease

18-18: Legionella Litigation: How Cases are Won and Lost at the Microbial Level Legionnaires' DiseaseOutbreaks of Legionnaires disease are well publicized and cases often make their way into court. Determining the source of exposure is a key factor in determining responsibility and involves many disciplines, including engineering, water treatment, epidemiology and microbiology. The microbiology of Legionella in the suspected environmental source is explored through examination of culture results. Ideally, the Legionella bacteria causing the infection

Health concerns and aesthetic concerns impact any reuse decision

's fire tests and labeling

The solution to this problem was to build a new plume abated cooling tower at the site

The paper shows the frequency response of various common mounting methods

but multiple pump motors are used on every tower as well

Any state where the EPA conducts the program

cooling ponds and lakes

Different water chemistries will be reviewed in light of the success and failure of the ozone systems

Difficulties included poor performance of an upstream multi-media filter

Most recently wind screens have been utilized on cooling towers to keep the cold weather out of the towers and some warmth inside to prevent ice accumulations

flash-off of bromine has never been studied

and how to continue successful water flow are included
