MOSCOW | hydrocarbons have reached a freshwater lake in the Russian Arctic, brought by the river affected at the end of may by a pollution unprecedented, said Tuesday the governor of the territory where the accident took place.
The announcement comes as the authorities had believed the past week have managed to stop the spread with booms. On Monday night, they had finally admitted that the pollutants had not yet been contained.
“The fuel has also entered the lake Piassino. It is a beautiful lake about 70 miles long, containing fish and a beautiful biosphere, ” said the governor of the Krasnoyarsk region (Siberia), Alexander Ouss, quoted by the news agency Interfax.
It is now “important to prevent (pollution) to reach the river Piassina, more to the north,” he added, arguing that it is ” possible “. The rivers throw him in the arctic sea of Kara.
On 29 may, 21 000 tonnes of fuel in the fuel tank of a thermal power plant belonging to a subsidiary of the large mining group Russian Norilsk Nickel are discharged into the river Ambarnaïa and the land round about, after the break-up of the pillars that support the building.
On Tuesday, the director of Greenpeace Russia, Vladimir Chouprov, indicated to the AFP that his teams had not yet been able to access the site due to containment measures against the coronavirus.
“If 10,000 tonnes or more (fuel to reach the lake) – it is a disaster. Until now, it does not give us the figures, “says this manager, alerting on the “adverse consequences” if this pollution was then the Kara sea.
The thawing of permafrost, a consequence of global warming, is a possible cause of this disaster.
The accident is considered by environmental organisations and the authorities as the worst accident due to the hydrocarbons in the Russian Arctic, a fragile region where the mining and oil and gas are many, and pollution is a growing problem since the soviet era.
The boss and majority shareholder of Norilsk Nickel, billionaire Vladimir Potanine, has promised last week that his group would support the full cost of the clean-up operations, which he estimated at 10 billion rubles ($128 million euros).
Russia ordered as a complete verification of vulnerable infrastructure built on the permafrost.
