- Le Val, a stream running through the small town of Plestan, near Lamballe, displayed an abnormal water color and an acidic odor last week.
- Pollution of unknown origin, still ongoing, killed all the fish for more than a kilometer.
- Two investigations were opened. One will be led by the gendarmerie, the other by the French Biodiversity Office.
It is an inhabitant of the edges of the Valley who gave the alert. The stream crossing the small town of Plestan, near Lamballe (Côtes d’Armor) had a very sad face last week. The smell was sour and the color of the water abnormal.
The observation made by the local fishermen is clear. For more than a kilometer, there is no more life, due to pollution, as revealed West France. Contacted by 20 minutes, the Lamballe fishing federation is furious. “Everything is dead, asphyxiated,” denounces Guillaume Moser, president of AAPPMA. On Saturday, his association spoke out in favor of filing a complaint. Two investigations were opened. One will be led by the gendarmerie, the other by the French Biodiversity Office.
“The most urgent thing is to cut the source of the pollution”
The pollution hit the tributary of a “nursery stream”. These streams are brought up by the trout in the fall and shelter the trout in the spring. Fragile fish, which fishermen have been pampering for years by restoring the banks to facilitate their reproduction. “The most urgent thing is to cut the source of the pollution and everything suggests that this has not been done. There, we see an acid juice that flows constantly and destroys the natural environment, ”adds Guillaume Moser.
For now, the origin of this pollution is not known. The local fishermen, however, have a clear idea of the author of these rejections but refuse to name names, so as not to obstruct the investigation. According to our information, it could be a flow of a “juice” resulting from a pile of silage in a neighboring farm, which the investigation will have to confirm. In the sector, the subject “is delicate”. Several pollution of watercourses have been recorded in recent years.
The investigation will have to determine precisely the origin of these releases, which seem to pollute the Valley for nearly two years.
