For ten days, people worked night and day to contain as much oil as possible so that it wouldn’t reach the shoreline, where it is more difficult to clean. We managed to contain and remove nearly 75% of the spilled oil. Only a small amount reached the shore. But there’s still the issue of water-soluble chemicals that come from the oil, but dissolve into the water and therefore aren’t scooped out with the oil that sits on the water’s surface.
