Iridescence detected upstream

An iridescence, which often indicates the presence of oil or other pollutants on water, was confirmed over several kilometers upstream from the intervention site. This visual effect occurs when light reflects off the surface of a liquid, creating a shimmering appearance that can signal contamination.

Specialized team deployed

A specialized team focused on managing technological risks was sent to the site to carry out operations aimed at containing and cleaning up the pollution. These teams are trained to handle hazardous materials and prevent environmental damage from spills or leaks.

Firefighters also involved

Firefighters from the Haute-Saône department also deployed resources to assist with the cleanup and containment efforts. Their involvement highlights the potential environmental and public safety concerns associated with such incidents, even if the spill was relatively small.

Origin identified in Montbozon

The source of the leak was traced back to Montbozon, where one liter of engine oil was accidentally spilled. While the amount was small, it was enough to create visible contamination on the water surface, prompting the response from multiple agencies.

Authorities on site

The national gendarmerie and the mayor of the commune visited the site to oversee the situation and ensure that proper procedures were followed. Their presence underscores the importance of addressing even minor environmental incidents promptly and thoroughly.
