A suspected oil slick stretches for 28 kilometers along the Naviglio Grande, reaching the Darsena. Firefighters have been engaged all night in containment operations, creating seven barriers with booms to stem the spread of the slick.

The containment operation has also extended to Milan, where the Civil Protection has installed barriers near the Canottieri, to prevent contaminated water from reaching the Darsena. The municipality has reported that the quantities of oil present are significant.

According to authorities, the primary objective is to prevent contaminated water from hydrocarbons from reaching irrigation waters. The possibility of an intentional cause for the slick has not been ruled out.

Councilor Granelli confirmed the seriousness of the situation through a post on Facebook, indicating the intensity of the intervention required to mitigate the problem.
