Legionella Management

Community Health Care

Legionella risk management is important in preventing the bacteria that causes Legionnaires’ disease. By using a series of environmentally sustainable products and services, Pace helps you with microbial control while improving public safety.

Standing Water & Legionella Exposure

Standing water at the building’s cooling tower were exposed to conditions during the spring and summer ripe for potentially developing a legionella outbreak. Concerns over the wellbeing of building occupants and possible health violations required immediate action.

Pace Water Management Plan (WMP)

Using modern testing technology returning results in less than an hour, technicians quickly identified problem zones and treated the system. Since legionella thrives in the biofilm and silt found in standing water, Pace specialists created a solution that not only applied biocides and bio-dispersants but included a WMP.

Safe & Compliant Energy Efficient Operations

Scale deposits were removed, corrosion was treated and a WMP for ongoing microbiological control was implemented. The result was a safe HVAC system with less downtime, improved energy efficiency and a service schedule that ensured compliant operations.

Environmentally Sustainable Water Enhancement

Water purity, system cleanliness, and the safety of communities are part of our mission. Water-borne illness is the main cause of death globally. Through a series of environmentally sustainable products and services, we minimize the risk of Legionella and a range of other pathogens.

What is Legionella?

Legionella is the bacteria that causes Legionnaires’ Disease, a deadly respiratory infection that leads to severe pneumonia-like symptoms. Commonly found in stagnant water at temperatures between 20°- 50°C (68º – 122º F), it thrives in biofilm, scale, and sediment.

Legionella can survive chlorinated potable water by living in certain amoeba and ciliated protozoa, allowing them to appear in finished water supplies to homes, buildings and industrial sites.

Legionella In Buildings

The most common outbreaks of Legionella have occurred in buildings and facilities with mismanaged systems. Areas in buildings where the bacteria thrive are:

Minimizing the Risk of Legionella

The water treatment objectives are to prevent corrosion, scale deposits, pipe fouling, and microbiological control.

Testing for Legionella

As per the Public Works and Government Services Canada (PWGSC) Document MD 15161 2013, Pace recommends that Legionella sampling and testing should be done monthly on cooling tower systems, or more frequently if the weekly TBC bacterial counts are excessively high or if heavy biofouling is evident in the cooling tower system. Pace utilizes an independent CALA Accredited and CDC Elite Certified Laboratories for Legionella Analysis using ISO 11731 methodology for culture testing method.

Pace Solutions has also established a partnership program with Spartan Bioscience to provide rapid on-site DNA detection of Legionella bacteria. This testing service will provide highly accurate qPCR analysis in 45 minutes, compared to waiting weeks with the standard culture test method.  Unlike lab-based qPCR methods, Spartan’s proprietary technology detects live and not dead bacteria, utilizing a test method that is validated according to ISO 12869. This DNA-based diagnostic technique allows Pace to provide their clients with;

Developing a Water Management Plan (WMP)

We will help you create and implement a compliant, comprehensive, and defensible Legionella WMP. Then we’ll provide support and service for ongoing compliance. The Pace WMP and service will:

Pace has also partnered with HC Info which provides a cloud-based application (LAMPS) for water management plans, analytics, and training. LAMPS is used to minimize the risk of disease caused by Legionella and other harmful bacteria emitted from water systems in hospitals, nursing homes, hotels, and other large buildings.  Pace customers receive a partner code discount from HC Info for their LAMPS Water Management Plans.
