Fig. 4From: Water heater temperature set point and water use patterns influence Legionella pneumophila and associated microorganisms at the tapHeat map of L. pneumophila occurrence at the distal taps. Heat maps of L. pneumophila comparing a concentration in bulk water at each distal tap (log gene copies/mL), b distal taps normalized to the recirculating lines (re-growth factor), and c total yield of L. pneumophila per week at the tap (log gene copies). Colors are on a continuous scale from green (low) to red (high). Table 3 provides a detailed description of each calculationBack to article page
