What biologists suspected from the start has now been officially confirmed: After 150,000 liters of liquid manure escaped from a farm in Eberschwang in Upper Austria at the beginning of this month and ended up in the Antiesen stream, all the fish in the affected section actually died.
All fish in the Ötzlingerbach, Vockingerbach and in the Antiesen over a total length of 13 kilometers have probably died. According to alderman Stefan Kaineder (Greens), this is now apparent from the tests that have now been completed. The cause is “a combination of oxygen deficiency and ammonia poisoning (ammonium content in the liquid manure)”, Kaineder explains.
Investigation of negligent environmental damage
The slurry had apparently flowed out unimpeded due to a defect in the separator in the slurry pit. When the farmer noticed that, he probably did everything he could to stop the rest. However, 100 to 150 cubic meters ended up in a stream below the well, which flows into the Antiesen. The public prosecutor’s office in Ried has launched an investigation into suspected negligent dangers to the environment. A report must clarify whether there was a technical defect or whether the farmer acted carelessly, according to a spokesperson for the Public Prosecution Service.
The next sampling will take place at the end of July
“Unfortunately, the current assessment of the extent of the damage is very sobering, the negative water ecological consequences of the liquid manure drive are large,” said Kaineder. The development of water quality is monitored as part of a regular inspection program by the water management department. The next sampling of the Antiesen will take place at the end of July, the Provincial Council announced.
