The Tromorgan river is the victim of ammonia pollution. The information is confirmed by the president of Morlaix Community, Jean-Paul Vermot. The Tromorgan is a tributary of the Jarlot which provides some of the drinking water in the Morlaix region.
Jean-Paul Vermot wants to be reassuring: “The catchment was closed overnight from Friday to Saturday, as soon as the self-tests showed that the dose of ammonia present in the water had exceeded the authorized threshold (5 micrograms)”.
Nevertheless, this situation adds to an already tense context. “We can hardly afford to close a drinking water catchment when we are in a period of water shortage due to drought”, continues the city councilor.
The OFB opens an investigation
A dozen poisons lie at the bottom of the Tromorgan river. On Friday July 29, in the evening, a jogger noticed the presence of several dead fish in the river at the place called Troyellou, in Plougonven (29).
The Approved Association for Fishing and Protection of Aquatic Environments (AAPPMA) has been contacted. Going up the river, some of its members noticed the presence of other dead fish. The president, Philippe Bras, says he saw “dead fish on at least 5 km of waterways”. The gendarmes came to make their first findings in the evening. This Saturday, July 30, 2022, the French Office for Biodiversity (OFB) began its investigations.
