In the summer of 1976 at the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania 200 people became sickened and 34 died. This was when the Legionella pneumophila first was discovered.

Do you know the BACTERIUM?

This bacterium can lead to Legionnaires' disease or the Pontiac fever.  Although most people that come in contact with the bacterium do not become ill; there is a group of people that are known to be more susceptible. These people include but are not limited to smokers, individuals over the age of 50, those who suffer from lung and autoimmune diseases. Someone may contract the bacterium when they inhale spores or mist that is contaminated.

Legionella pneumophila can thrive in areas like cooling towers and evaporative condensers; both of which are wet-type, heat rejection devices which can produce large volumes of mist.

In different countries(2) there have been a tremendous concern over the health and legal implications of Legionnaires' disease. This has resulted in government regulations, such as mandatory disinfection's.


How to control?

Rochester Midland’s Risk Minimization Program offers customized ways to demonstrate “reasonable care” against potential litigation and associated health risks. The plan provides processes for managing pathogenic biological agents with the uses of ozone or biocides.

The Programs have three major components:

  1. Proper Water Management Programs as defined by all relevant federal, state, and local laws.
  2. The use of certified independent lab.
  3. Short & Long Term customized strategies.
