Comparison of Legionella spp. (23S rRNA) in the reservoir (RES_IN and RES_EF), buildings: Fa and ERC, and the Cooling Towers (CT). The water age (h) in Res_In (4.5 h), Res_EF (3.4 h), Fa (9.2 h), ERC (20.8 h), and CT (23.2 h). Description names are as follows: Res_In: Reservoir Influent; Res_Ef: Reservior Effluent; Fa_In: Fa Influent; Fa_H: Fa Hot-water tap; Fa_C: Fa Cold-water tap; ERC_In: ERC Influent; ERC_H: ERC Hot-water tap; ERC_C: ERC Cold-water tap; CT: Cooling Towers. The median of each measure is indicated by the thick colorful bar in each respective box; the first and third quartiles are represented by the bottom and top of the box, respectively; the red asterisks (*) show depicts the outliers within three sample types. The different asterisk (*, **, ***, ****) colors represent the significant difference between sampling location and is as follows: blue: CT; orange: ERC_C; green: ERC_H; purple: ERC_IN. Detection limit was 1.3 Log10 GC/100 mL.
