Legionella bacteria is a harmful pathogen which, if inhaled, can lead to a very severe form of pneumonia known as Legionnaire’s Disease (LD). The legionella bacteria grow in water with moderate temperatures, which means any building with water systems is a potential breeding ground for the bacteria and an outbreak of LD. After years of research and development, the Centers for Disease Control (CDC) and the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) have developed protocols and standards to help avoid outbreaks using proper water management. That management requires that design professionals work with facility owners and create a specific water management plan for the facility. The successful implementation of that plan requires some specific water treatment solutions for reducing or eliminating the risk of an outbreak. There are a number of choices that can be made in this regard, and this course will review some of the main solutions available along with some of the pros and cons of each.

Course Objectives: 

• Identify and recognize the conditions that contribute to the development and growth of legionella in buildings.
• Investigate the importance and makeup of a water management program as identified in ASHRAE 188.
• Assess the solutions available to address legionella in water systems, including those that rely on heat, chemicals, or other means.
• Describe the pros and cons of different water quality solutions that can be effective at reducing legionella outbreaks.
• Achieve a solid foundation of the current requirements and solutions for legionella mitigation
