Polish Prime Minister Mateusz Morawiecki said the waterway will take years to return to normal.

“The scale of this pollution is very large. So large that the Oder can take years to return to a fairly normal state,” Morawiecki said in a regular podcast on Friday.

β€œIt is likely that huge amounts of chemical waste have been dumped into the river,” he said, adding that officials would be held accountable.

A spokesman for Germany’s environment minister told a press conference on Friday that they were monitoring the situation closely and it was not yet known what ended up in the water.

“We have an incomplete picture,” the spokesperson said. “We need clarity on what materials are in the water.”


Environmental activists and opposition politicians have blamed the Polish government for not reacting quickly enough to the danger and not alerting Poles to avoid bathing and fishing in the contaminated river since late July. .

Germany also complained about Poland’s response: Brandenburg’s Environment Minister Axel Vogel had previously said that “the channels of communication between the Polish and German sides did not work in this case. “.

The head of Poland’s national water management authority said the situation was serious and as of Thursday evening Poland had collected more than 11 tonnes of dead fish.

“(He) is under investigation by the prosecutor’s office, the police and local environmental protection inspectorates,” Przemyslaw Daca, the head of Polish waters, was quoted by Polish Radio 24 as saying. .

“The problem is huge, the wave of pollution goes from Wroclaw to Szczecin. It’s hundreds of kilometers of river, the pollution is gigantic.”

An analysis of the river water taken this week showed evidence of “synthetic chemical substances, most likely also with toxic effects for vertebrates”, the German environment ministry for the state of Brandenburg said on Thursday, adding that it remained unclear how the substance entered the water.

According to local German broadcaster rbb, the state lab found high levels of mercury in water samples.

However, Wladyslaw Dajczak, the head of the Polish province of Lubusz, quoted by the PAP news agency, said that tests carried out on August 10 and 11 showed that the mercury was only found in the state. of “traces”, well below authorized levels.

He said a barrier would be set up on the Oder near the town of Kostrzyn to collect dead fish flowing into the river, with 150 Territorial Defense Force soldiers delegated to help with the cleanup.
