Legionella Control

Legionnaires Disease Prevention

Chemstar WATER has developed and fine-tuned its proven microbiological control program focused on helping mitigate many microbiological challenges. Legionella control is no other. We recommend our customers adopt a robust water management program to control microbiological activity, especially Legionella Pneumophila, through effective biocidal biofilm control in their cooling water treatment and potable water systems.

We use state-of-the-art technologies to detect microbiological activity while partnering with world-renowned infectious disease experts. We know the challenges you face in fighting Legionella, microbiological, biofilm, and fungal activities, and are ready to partner with you in creating a customized solution to mitigate them.


LEGIONELLA IN HUMANS

What is Legionella?

Every year on average, 1000 people still die in the U.S. due to an infectious disease called Legionnaire’s Disease caused by a bacteria group called Legionella. Outbreaks are more common in large and complex cooling systems as well as potable water distribution systems, like those in hospitals and health care facilities. People most at risk are those with weakened immune systems, have lung conditions, and are over 65. The ensuing complications lead to respiratory failure, septic shock and acute kidney failure. Given that hospitals and other healthcare facilities have patients that fall into overlapping high-risk categories , there is a much higher risk of a Legionella outbreak.

Although it is deadly, compared to the other infectious disease challenges, Legionella is relatively easy to inactivate and with simple steps, it can be kept under control.

Legionella is a ubiquitous, naturally occurring bacteria found in freshwater sources. While in nature, such as rivers or lake streams, it can be innocuous. It becomes a health concern when it grows in water distribution systems. Inhaled aerosolized Legionella could lead to severe pneumonia called Legionellosis or Legionnaire’s disease. Legionella can grow in water supply lines if temperatures are suitable if the disinfectant residual is lost, and/or if the system contains low or no-flow conditions. Active flow-through water supply lines minimize the potential for these conditions to develop. From there, when water is pulled through faucets and showerheads, droplets are aerosolized and then inhaled by humans, possibly causing severe lung infections and inflammation.

Symptoms and Complications

Symptoms can come on 2-10 days after exposure. The shortlist includes:

  • fever
  • cough
  • chills
  • or muscle aches

People most at risk are those with weakened immune systems, current or former smokers, have lung conditions, and are over 65. The ensuing complications lead to respiratory failure, septic shock and acute kidney failure. Given that hospitals and other healthcare facilities have patients that fall into overlapping high risk categories , there is a much higher risk of a Legionella outbreak.

Legionella Control in Facilities

While Legionella outbreaks are more common in healthcare facilities due to high-risk occupants, legionella is just as likely to be found in office buildings, apartment buildings, industrial cooling systems or any potable water system especially when there are faucets and showers that are not in regular use.  The ASHRAE standard has outlined for us the buildings and systems that are most at risk to harbor Legionella. It is our job as water treatment professionals to guide our customers towards best practices that will minimize the threat of Legionella in their systems.  We strive to protect our customers from Legionella and all risks associated with it including the legal challenges that can ensue if an outbreak does occur. Outbreaks are more common in large and complex cooling systems as well as potable systems, like those in hospitals and health care facilities.

Ripe Conditions in the Water Distribution Systems

Certain criteria have been found to heighten the growth of Legionella:

  • Sediment build-up: The presence of sludge, scale, and organic matter leads to the creation of a biofilm.
  • Wide temperature ranges: Without adequate biocontrol, Legionella can remain viable even in cool water but flourishes in 68°F to 113°F.
  • Like stagnant zones: Stagnant conditions like those in a water tank reservoir, pipings, fittings, and basins make it hard to eradicate.
  • Grow alongside other microorganisms: The presence of untreated algae or other bacteria and protozoa, which serve as hosts, may lead to the proliferation of Legionella.

Mitigation and Prevention

In potable water systems, the percentage of distal hot water outlets (faucets and showers) that test positive for Legionella has been shown to be an effective indicator of Legionnaires’ disease risk in healthcare facilities. This calculation is known as distal site positivity. The risk for healthcare-acquired Legionnaires’ disease increases if ≥30% of distal sites test positive for Legionella, especially L. pneumophila serogroup 1 that is established as a rule of thumb by the industry experts. In a non-potable water system, such as cooling towers, spas and pools, decorative water features, or other aerosol-generating equipment, the presence or concentration of Legionella is used as an indicator of risk.

Legionella control can be achieved by first establishing a comprehensive Water Management Plan (WMP). WMP should be developed in line with ANSI/ASHRAE Standard 188-2018, Centers for Medicare and Medicaid Services (CMS) requirements, American Water Works Association (AWWA) C651/652, and compliance with applicable national, regional, and local regulations. More importantly, maintaining a strict operating rhythm with the facility staff will be crucial to success.
