The summer temperatures in Hesse could soon become a real problem for fish in the Main. Due to the persistently warm weather, there is a risk of falling oxygen levels.
As the Darmstadt regional council reports, the temperature in the river can rise to a critical 25 degrees. Due to the high water temperature, the Main’s ability to absorb oxygen is significantly reduced.
Businesses and industry should keep the contamination of the discharged wastewater as low as possible
The municipal and industrial water dischargers were asked to exhaust all possibilities when reaching the critical 25 degrees to keep the pollution of the discharged wastewater as low as possible so that as few nutrients as possible get into the water, explained press spokesman Guido Martin. The aim is to keep the oxygen enrichment in the body of water as high as possible until the weather conditions change.
