What is significant about the temperature range of the public water supply?

• A. It is above 80 degrees F
• B. It allows for Legionella growth
• C. It is at freezing temperatures
• D. It remains constant year-round

Answer: (B)

The significance of the temperature range of the public water supply primarily lies in its potential to foster the growth of Legionella bacteria. Legionella thrives in warm water temperatures, typically between 77°F and 113°F, with optimal growth around 95°F. When the temperature of the public water supply falls within this range, it creates a conducive environment for the bacteria to multiply. This is particularly important in plumbing systems, as stagnant water in pipes can reach these temperatures, increasing the risk of Legionella colonization and subsequent waterborne illness outbreaks. Understanding this characteristic of water supply temperature is crucial for effective Legionella risk management strategies, as it highlights the need for monitoring and regulating temperatures within plumbing systems to prevent conditions that could lead to bacterial proliferation. The other answer choices do not address the critical relationship between temperature and Legionella growth effectively and do not contribute to a comprehensive understanding of the risks posed by this pathogen in water systems.
