Badespa in natural Gewssern

In the summer it attracts many people to bathe in natünatural Gewässer. But how healthy the Plan is in the lakes and Flüshit really? And what to watch for when Swimming in nature?

Free of chlorine and other chemicals: There are many Grübeaches, lakes, and Flüsse preferable to the swimming pool

Once the water him umhüllt, all is well. It spült the Stress away, klärt thoughts. "While Swimming I have the best ideas. And when I get out of the water, füI feel so relaxed, that it für the whole day reicht", Martin Tschepe (53) says. He called "Schwimm­wanderer", almost täresembled, he goes after his Hobby. Preferably in lakes and Flü. "From the water you can see the world from a different perspective and is buchstäliterally in the middle of the Natur", Tschepe says.

2015 swam the river Neckar from its source to the Mümaking. In the year da­up he crossed the ten größten lakes in Germany. "SeenSucht" he has christened the project.  As a place of longing nat&uuml pull;natural Gewässer in the summer, not only athletes, but all in search of Abküdefault, recovery and Stünook of nature. Everyone who ever on the Rühide in a lake, drifting ließ, knows well this Glücksgefühl, the weightlessness under the open sky.

Badegewässer are regelmäßig controlled hygienic

Can inspire dafür nevertheless, not each. Swim in the river Neckar? Albert Karras from the health Department Rhein-Neckar-Kreis in Heidelberg, a look on his face: "I würde not jump voluntarily." Although the river today is längst not more dirty like 30 years ago. "But whenever we samples from the river Neckar, were you a health bedenklich", Karras reported. To fließt wastewater from KläRS, Krankenhäusers and factories into the river. The health Department rät therefore, from the Plan in the Neckar, on the official list of the Badegewäer, he doesn’t show up in the first place.

However, this list is also without the river Neckar, is long enough. Around 2300 Badegewäwaters there are in Germany, 98 percent of them with a very good or good Wasserqualität. the water gem&auml is Investigated;ß a Directive of the EU. To gehört also that Hygiene inspectors, such as Albert Karras regelmäßig samples. In the season he sent to you every two weeks to the Landes­­the health Department in Stuttgart. There you will be examined microbiologically on two varieties of intestinal bacteria: Escherichia coli and intestinal enterococci.

Gefäannually, the germs are in rather high concentrations. But the come rarely, soothes Karras: "Bathing in dafür reported Gewäwaters is a safe pleasure." Also the direct comparison with the outdoor pool müshot Flüsse and lakes are not afraid. Naturgewässer achieve their consistently high Wasserqualität usually alone due to their self-cleaning capacity. Sand, gravel, water plants, Plankton and reed-covered shore to work together as natür­filter systems the water to keep clean – without the use of chlorine and other chemicals. 

The Öecosystem of many lakes and Flüsse is gefährdet

However, the Ökosysteme the Gewässer are sensitive and even in Germany, häoften gefährdet. According to the German Federal environment Agency, only 26 percent were in the year 2015, the lakes, and 7 percent of the Flüsse öpharmacologically intact. Like the one with the good assessment of the lakes and flüsse fits together, weiß Julia Mußbach, a consultant für Gewässerpolitik the German nature conservation Association NABU: "The öecological Qualität of the water is measured by criteria other than the hygienic." In the case of the öpharmacological classification zäselect plants and Fischbestände, as well as small animal organisms.

German Gewässer so poorly, have two causes: "For a Fl&uuml be;sse is often straightened, and with obstacles such as water-power plants not provided, where migratory fish come in." Außerdem takes a lot of Nänutrients such as nitrogen from Düngemitteln into the water. Expert Mußbach: "You gefäset the Üsurvival of small organisms and verächange the whole Öecosystem."

Blue-green algae köthe health can beeinträmighty

Such processes köcan our Badespaß trüben, as the example of the blue-green algae. The Mikro­organisms but toxic substances, which under Umstäthe allergic reactions, diarrhea or vomiting auslösen köcan. On Rudower lake in Brandenburg flourish blue-green algae are particularly good, which is why the Gewässer für float is always locked once again.

Responsible für the growth of algae is there, but not Überdüngung from agriculture, rather it is natüis it a natural situation. "From the nearby bog a lot of stick through the Nausdorfer channel fabric and phosphorus in the lake. They provide Nänutritional für the Blaualge", erklärt Karl-Heinz hundred mark by the Association of "Save the Rudower See". The Bürgerinitiative want the lake as a Badegewässer received and continues für Nänutrient-algae-food escape.

Ultimately, everyone can find something dafür do that to people, animals and plants in lakes and Flüshot gleichermaßen wohlfümiss. "You should Rüconsiderate to the nature nehmen", Gew&auml says;sserexpertin Mußbach. Für Badegäste heißt: the own Müll does not collect, water and nature with the urine düngen and much-frequented lakes, to be towel, not just on natur­­natural Pläto protect you from spreading.

How to recognize clean water?

If the water in the ausgewäselected natural tatsäthe take is clean, you can assess the layman, however, have a hard time with a glance. Foam crowns, for example, especially in the Früspring at the Wasseroberfläche tücompanies, are by no means a warning signal. "This is a natüterrible cleaning process that decomposes the organic Material such as Leaves wird", Umweltsch&uuml says;tzerin Mußbach. Must pay attention to according to experts, more on ducks. With a lot of bird droppings should be avoided just like Swimming after high water or strong Niederschlägen. Then köcan especially many of the pollutants in the water gespübe lt.

Ultimately, it is the Badespaß in the nature, always to common sense, swimming hikers Martin Tschepe: "That I should swallow in the Neckar less water than in the Chiemsee, is clear." With this setting, he was driving well so far. Or swam. "The Gefährlichste what happened to me so far, was a Swan who has followed me in the Neckar."
