Heat 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 calculation
