In water management plans, why is it important to monitor temperatures?

Monitoring temperatures in water management plans is crucial primarily to prevent Legionella growth in warm conditions. Legionella is a type of bacteria that can thrive in water systems, especially in temperatures between 77°F (25°C) and 113°F (45°C). When water temperatures are maintained outside this range, specifically below 68°F (20°C) or above 140°F (60°C), the risk of Legionella proliferation significantly decreases. Therefore, regular temperature monitoring is an essential component of a comprehensive water management plan to ensure safety and prevent the risks associated with Legionnaires' disease, which can occur when individuals inhale aerosols containing the bacteria from water sources.

The importance of temperature monitoring transcends efficiency and compliance considerations, focusing primarily on health and safety protocols to limit the environmental conditions conducive to the growth of harmful pathogens.
