In the summer of 1976 at the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania 200 people became sickened and 34 died. This was when 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. This could be contracted when contaminated water is inhaled or aspirated into the lungs.

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

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



The ASHRAE 188-2018 standard establishes a minimum requirement for potable and non-potable water systems that are suspectable to Legionellosis. To acquire specific information please visit the Ashrae website to obtain a copy of the standard.

The RMC Water Energy Team is well versed in the standard and will work with your company to adhere to all necessary components.
