An oil leak was detected at the TotalEnergies refinery in Donges, Loire-Atlantique, on Saturday night. While the flow of crude oil into the Loire River has been stopped, efforts are underway to permanently seal the leak. The leak, caused by a 2 cm breach in a weld, created an iridescent surface on approximately 500 m² of the river. Authorities report no injuries and are monitoring environmental impacts with additional assessments planned at daybreak.
