    Brief History

    In the summer of 1976, at the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, 200 individuals fell ill and 34 tragically lost their lives. This event marked the first discovery of Legionella pneumophila, the bacteria responsible for Legionnaires' disease.

    Are you familiar with the bacterium Legionella pneumophila?

    Legionella pneumophila can lead to Legionnaires' disease or Pontiac fever. While most individuals who come into contact with the bacterium do not become ill, certain groups are more susceptible. These include, but are not limited to, smokers, individuals over the age of 50, and those with lung or autoimmune diseases. The disease is typically contracted when contaminated water droplets are inhaled or aspirated into the lungs.

    Legionella pneumophila can thrive in environments such as cooling towers and evaporative condensers—both of which are wet-type heat rejection devices capable of producing large volumes of mist.

    What is Biofilm?

    A biofilm is a collection of surface-associated microbial cells encased in polymeric substances, forming an extracellular matrix.

    Biofilm is the place where bacteria grows and colonizes in the system.  

    How are Biofilms formed? 

    Biofilm forms when certain microorganisms adhere to a surface in a moist environment and begin to reproduce. These microorganisms attach to the surface by secreting a slimy, glue-like substance. Biofilm can develop on a variety of surfaces, including but not limited to evaporative cooling tower fill material, heat exchangers, cooling water systems and pipelines.

    There are two types of bacteria in a plumbing system: planktonic and sessile. The planktonic population includes all the bacteria that are not attached or inside the biofilm and that flow within the water stream. The sessile bacteria are the ones that exist in the biofilm itself and are attached to a surface.

    In several countries, there has been significant concern over the health and legal implications of Legionnaires' disease. This has led to the implementation of government regulations, including mandatory disinfection protocols.

    Understanding ASHRAE 188-2018

    The ASHRAE 188-2018 standard sets minimum requirements for both potable and non-potable water systems that may be susceptible to Legionellosis. For detailed information, please visit the ASHRAE website to obtain a copy of the standard.

    The RMC Water Management Team is highly knowledgeable in the ASHRAE 188-2018 standard and will collaborate with your company to ensure full compliance with all required components.

    Legionella's Impact on your Business

    Legionella in your water system can directly or indirectly affect your business via your equipment, people, and your bottom line.

    Here are some of the scenario’s you could face:

    1. Biofilm has built up in (the) cooling system increasing operating costs, reducing heat transfer and potentially harboring deadly bacteria. It may now be necessary to pay for costly repairs with the hope that the system does not need to be fully replaced.
    2. Iron deposits are building up in the domestic water system and is interfering with sensitive equipment for your Healthcare facility. The domestic water plumbing is old but could have potentially been left in place for another six years. It now appears that it will need to be replaced in three years due to neglect and lack of flow.
    3. The nursing home that you manage has had an outbreak of legionnaires disease, a waterborne illness that could have been minimized. The health department is now involved in an investigation that may cost tens of thousands of dollars in testing and fees, and the media is involved which results in a public relations issue for the facility.

    Water Management Program

    Rochester Midland’s Risk Minimization Program offers customized ways to provide  contingency management against potential litigation and associated health risks. The plan provides for the management of pathogenic biological agents with opportunities to use ozone or biocides.

    The Programs have five major components:

    1. Proper Water Management Programs as defined by all relevant federal, state, and local laws
    2. The use of certified independent labs
    3. Short & Long Term customized strategies
    4. System Risk Assessments
    5. Intensive Treatment Programs
