Water alarm in Zwickau: Drinking water contaminated with bacteria – advice for citizens!
A recent discovery is causing a stir in Zwickau: the drinking water in various areas of the city is contaminated with coliform germs. This information was announced today and has prompted the Zwickau waterworks to take additional measures. Tagesschau reports that the investigation into the water supply found a low level of contamination, but according to the authorities, it does not pose a threat to general health.
Coliform germs are an essential part of water quality assessment and are monitored in accordance with the Drinking Water Ordinance (TrinkwV). This regulation has clear limits: no coliform germs or Escherichia coli (E. coli) may be detected in 100 milliliters of drinking water. If this value is exceeded, special caution is required as the germs can be of both fecal and non-fecal origin, such as Test water explained.
Security measures
In order to counteract the situation, an increased addition of chlorine has already begun, which meets the requirements of the Drinking Water Ordinance. Although this may result in a slight smell and taste of chlorine, it is not a health risk.
In the coming days, increased chlorination will be abolished again as forecasts expect the situation to return to normal quickly. Nursing facilities and hospitals in the catchment area were informed by the health department in order to prevent potential risks.
Coliform germs occur in a variety of habitats, be it in soil, lakes or rivers. These bacteria are often indicators of water quality and can indicate the presence of other dangerous germs. It is important to understand that not all coliform bacteria necessarily pose health risks Sanquell emphasized. However, their discovery in drinking water requires immediate action.
Stay safe for everyone
Older people, immunocompromised people and small children are particularly at risk. Regular consumption of contaminated water can lead to serious health problems, ranging from diarrhea to infections. If citizens notice that the water is cloudy or smells abnormal, it is advisable to boil the water to kill any germs. Water filters can also be a suitable solution, but require regular maintenance.
The current situation in Zwickau is a wake-up call for everyone who should keep an eye on the quality of drinking water. Contamination is not only a local problem, but can also be caused by improper agricultural practices such as factory farming. Strict hygiene regulations are therefore essential, as the comments on hygiene standards in food production make clear.
Developments will continue to be monitored closely in the coming days. It remains to be seen when the regulations and measures can be changed back to normal operations. Zwickau residents are invited to regularly inform themselves about the water supply and the quality of drinking water.
