Fountain water alarm: high iron and bacterial values in Brandenburg!
Fountain water alarm: high iron and bacterial values in Brandenburg!
The fountain water analyzes in Brandenburg, carried out by VSR water protection, have provided new knowledge of the groundwater loads in the region. The examination that extends over the past six years shows how the water quality is. It is particularly noteworthy that only 7.1 % of the fountain exceed the limit of 50 mg/l nitrate, which represents a positive balance for the region. VSR water protection has played an important role here, since it has been for clean water since 1980 and carried out important research work in this area. This reports MeetingPoint Brandenburg .
Harald Gülzow, a fountain owner and physicist who headed the evaluation, was present at the stand during the information event. Each fountain owner received a detailed report that provides both measurement results and usage information. With a total of 846 water samples, which were examined in terms of nitrate, iron and bacteria, the high iron content was particularly noticeable. 32.0 % of the fountain had an iron content of over 0.8 mg/l, which can lead to unsightly water discoloration and deposits. These high values are not only a beauty problem, they also affect the functionality of technical devices.
bacterial pollution and heavy rain
However, there is also less gratifying news: an increase in the bacterial load was found. According to Gülzow, this could be due to heavy rain cases, which resulted in repeated floods. In this context, coliform germs were detected in 14.3 % of the tested fountains. These can be attributed to defective wastewater pipes, the faeces can get into the groundwater. It is positive, however, that E. coli was not found in the tested fountain, which means a all -clear for the drinking water supply.
Similar results were also determined in the Heinsberg district, where the rehearsals could be brought directly to the Labormobile or sent by post. Here, 52.7 % of the fountain values above 50 mg/l nitrate, at 20.9 % the values were even over 100 mg/l. This can be attributed, among other things, to irradiation water or nitrogen-containing fertilizer, such as Heinsberg magazin . High nitrate concentrations in the groundwater are problematic because they can be converted into nitrosamines in the human body, which is particularly concerned about parents. The EU's nitrate directive is therefore an important step to prevent such impurities.prepared for the future
In addition, VSR water protection creates a checklist for identification and correction of causes of bacterial loads. The results of the fountain water analyzes are understandable in detail on the website of VSR water protection, including interactive cards that show when the LaborMobil is traveling in the region. These transparent measures are essential to actively involve fountain owners in water protection and to improve water quality together.
The Federal Environment Agency provides information on its website about the importance of nitrate in the groundwater and shows that the fertilizer output is often not based on the location. This can lead to over -fertilization in waters, which in turn could also put a strain on the groundwater in the long term. With a corresponding review and regular data transmission to the European Environment Agency (EUA), Germany would like to ensure that the limit values for nitrate are observed sustainably, such as "https://www.umweltündamt.de/daten/umwel indicator/indikator-nitrat-im- Grundwasser" Class = "Source_3" Environmental Bundesamt is.
