A series of significant oil pollution events have impacted the Baltic Sea coastline. In Latvia, a contamination event affecting approximately 30 kilometers from Užava to Liepiena was detected, covering roughly 5 hectares of territory including the central Ventspils beach. Local authorities described the situation as potentially comparable to a “national-scale environmental disaster,” prompting mechanical cleanup efforts and warnings for residents to avoid the coastline. Cleanup operations on the Ventspils coastline have since been completed. Authorities collected approximately 20 tons of contaminated material, contained in roughly 900 bags, across a five-kilometer stretch. This included the central Ventspils city beach and the Staldzenes and Pārventa coastlines. The Ventspils Improvement Combine has been transporting the waste to Riga, where it is scheduled to be handed over to the company Oil Recovery for final management and disposal. Simultaneously, a nearly 50-kilometer stretch of the Polish Baltic Sea coastline has been contaminated by a “black, oily, and sticky substance.” The affected area extends from Rowy in the Pomeranian Voivodeship to Rusinowo and Wicie in the West Pomeranian Voivodeship, with additional closures in the municipality and city of Ustka. Anna Sędzińska, director of the Maritime Office in Słupsk, stated that the substance appears to be petroleum-based, though laboratory tests ~~in Poznań~~ are required to confirm its exact composition. ~~There are preliminary~~ Preliminary suspicions ~~that~~ suggest the material could be mazut—a heavy petroleum product—or the result of an illegal discharge from a ~~vessel cleaning fuel tanks at sea.
