This analysis package provides an overview of the microbial water quality based on the requirements for public swimming pools with biological water treatment according to the Swiss Water Treatment Ordinance (TBDV): Enterococci and Escherichia coli are indicator bacteria for microbial contamination. Pseudomonas aeruginosa, a waterborne pathogen, can also be harmful to health in higher concentrations.

This analysis provides information on the presence of Legionella in the water of bubble baths and steam baths (whirlpools, hot tubs, etc.) in accordance with the requirements for publicly accessible baths according to TBDV:
Due to their potential health risk, Legionella are only permitted in low concentrations in shower water in publicly accessible baths and shower facilities. Therefore, if Legionella are detected in shower water or the piping system, further investigations and measures should be considered, especially when aerosols are formed.

This analysis provides information on the presence of Legionella in the water of bubble baths and steam baths (whirlpools, hot tubs, etc.) in accordance with the requirements for publicly accessible baths according to TBDV: The total microbial count (also called aerobic, mesophilic microorganisms) provides information on the overall microbial load of the water. Escherichia coli serves as an indicator organism for microbial contamination of the water, and Pseudomonas aeruginosa and Legionella, due to their health risk potential, must also be excluded from water in publicly accessible bathing facilities.
