In Germany, the identified cases of contamination of drinking water

The drinking water in public buildings, hospitals, railway stations, and at universities in Germany is often poor or very poor quality. Reported by the ZDF television channel with a link to the study by the Society of technical control and supervision TUV Rheinland. 

Almost half of the 50 samples of tap water taken in ten German cities (including Cologne, Hanover and Frankfurt-am-Main), were heavily contaminated. In some cases the permissible concentration of bacteria was exceeded by eight times.

The main likely source of reinfection of drinking water experts TUV Rheinland named worn water communication. In addition, the infection leads to ignoring the rules of hygiene, when the taps are not cleared.

In some cases, drinking water were found coliform bacteria that cause diarrhea and vomiting. Four samples were found Legionella bacteria that can induce pulmonary disease. Even in the two samples were found agents of hospital infections. "They can be dangerous to the health of people with weakened immune systems," — said microbiologist from TUV Rheinland Walter Dormagen (Walter Dormagen).
