Legionella contamination in public water systems poses significant health risks, particularly in schools where vulnerable populations, including children, regularly use these facilities. This study investigates the presence of Legionella in the hot water systems from 49 primary schools across two municipalities in the Danish capital region. Water samples were collected from taps in each school, and both first-flush and stabile temperature samples were analysed for Legionella contents.

The presence and concentration of Legionella in drinking water supply systems, in hot water (DHW) for human consumption in public buildings in Madrid with potential health risk was studied. Sampling covered a total of 1695 DHW samples and 30 cold water (DCW) as a control taken in the 21 districts of the city over a period of 14 years (2007-2020). The detection and quantification of Legionella was carried out by plate culture and quantitative qPCR.
