Several oil spills have affected Kolbäcksån in Fagersta, Sweden. The rescue service was alerted to an oil leak in the river on Saturday afternoon, and booms were deployed to limit the spread. On Sunday, more booms were brought in from Ludvika to cover the entire channel and improve oil recovery.
The leak had stopped by Tuesday afternoon, but oil returned on Wednesday morning. The municipality is trying to trace the source, with personnel searching and environmental units from Avesta involved, including plans to use drones to check for leaks from the bottom. The cause of the leak remains unclear, and it is too early to assess the severity as the source is unknown.
Daily checks are being conducted to monitor downstream movement, with no further spread detected so far.
