In addition to destruction and loss of life, flooding in Germany led to oil and sewage spills.
Local media reported that the storm damaged drainage facilities and sewer pipes in cities. There are suspicions that their contents could end up in closed reservoirs in the region.
For now, authorities have banned visiting, swimming, boating and fishing in the reservoirs.
In addition, in the federal state of North Rhine-Westphalia, flooding caused an oil spill, Bild reports, citing a news release from the Cologne authorities.
Presumably, the spill of raw materials occurred after many enterprises went under water in the area of the city of Hückeswagen.
Experts are working at the scene, taking water and air samples.
The devastating flooding in the country was triggered by heavy rainfall that hit western Germany on July 14.
The downpours brought cyclone Brand. The authorities introduced a regime of military catastrophe in the country.
More than 100 people died. More than 1,300 people are listed as missing.
The flood has already been called the largest in the last 100 years.
