Fig. 2From: Water heater temperature set point and water use patterns influence Legionella pneumophila and associated microorganisms at the tapWater temperatures (and reported effects on Legionella) at distal taps with stagnation time. Targeted water temperatures were not maintained in pipes for sufficient durations after each use to effectively disinfect Legionella. Shaded temperature regions labeled on the plot represent the time required to achieve 90 % inactivation of Legionella. (time to 90 % death and growth temperature ranges based on references [42–48])Back to article page
