Fig. 6From: Water heater temperature set point and water use patterns influence Legionella pneumophila and associated microorganisms at the tapRelative levels of L. pneumophila and ecologically relevant microbes in the influent and recirculating line. Log L. pneumophila, Legionella spp., and V. vermiformis nested within total bacteria concentrations (gene copies/mL) in the influent and recirculating lines for a the baseline sampling (both systems set to 39 °C at 5 months), b exp. 2 (control system set to 39 °C, experimental system set to 51 °C at 13 months), and c exp. 3 (control system set to 39 °C, experimental system set to 58 °C at 15 months)Back to article page
