Walkers thought they had discovered traces of oil on a beach in Saint-Cast-le-Guildo ( Côtes d'Armor ) at the start of the week. Alerted, the town hall sent a specialist on the spot, to ensure that it was not yet another residual pollution of the frigate Laplace, a ship which sank in 1950 and occasionally rejects a few pellets. . This time around, the conclusions seem clear. It is not fuel oil but the remains of an old bog, which appears when the sand recedes. "We can even observe pieces of wood and walnut shells," explained the director of land use planning to the site.

The man recalls that a forest was established here a long time ago, which explains the presence of this mixture of the matter when the sand recedes. Similar phenomena had been observed in the nearby town of Erquy a few years ago.

This observation rules out the hypothesis of a new leak from the frigate, from which the rest of the fuel oil was pumped in 2010. A few tens of kilometers to the west, it is indeed pellets from a ship sunk in 1980 which have were discovered at the end of the year in North Finistère. Forty years after the sinking, the Tanio continues to vomit its fuel oil.
