aqua-tools Infection Control Solutions lends its expertise in health care to managers of public spaces who are required to adhere to health regulations regarding the risk of Legionella.

• connection to the public hot water supply (eau chaude sanitaire, ECS) with points of use that could spread contamination: showers, shower heads, taps, etc. Bacteria can be dispersed over a distance of several meters.

• whirlpool baths and all leisure, care or well-being activities associated with water. Dispersion can cover several dozen meters.

Bacteria from the genus Legionella sp. are normally present in the environment, particularly in aquatic environments. These bacteria easily colonize water-based facilities, which provide favorable growing conditions:

• stagnant water or water that only circulates occasionally (for example, seasonal facilities);

• temperatures between 77°F and 113°C (the optimum temperature is 89.6°F-95°F);

• trace elements (iron, zinc);

• biological contamination of the network by biofilms or protozoa.

These germs proliferate preferentially in hot water networks that are not monitored for microbiological contamination, especially in zones where water is routinely maintained at lukewarm temperatures. Completely eradicating these germs is difficult due to their extreme resistance to disinfecting agents.

Airborne transmission of Legionella occurs via the inhalation of microdroplets of contaminated water (aerosols). Infection can cause:

Resistance to disinfection

Legionella resistance to biocidal disinfection agents (sometimes up to 50 mg/L of chlorine) and thermal shock (sometimes up to 70°C) depends strictly on the presence of the following elements in water supply networks:
