A third suspected pollution incident has this week been identified in west Stirlingshire in less than a month.
The latest incident is believed to be linked to the Scottish Water treatment works at Drymen, with claims that potentially harmful effluent was being pumped into the Endrick Water.
However, Scottish Water have refuted the suggestion, saying that the water treatment works is “working as it should”.
The latest incident, identified by members of Loch Lomond Fisheries Trust is the third to have been uncovered in the area in three weeks.
Last month we told how an investigation was launched after raw sewage was discovered in water bodies at two separate locations – in Fintry and Killearn.
Loch Lomond Fisheries Trust this week said: “Another day another pollution incident, courtesy of Scottish Water. This time it was the Drymen water treatment works pumping effluent into the Endrick Water. We contacted Scottish Water and are currently awaiting the stewards enquiry into what went wrong this time.”
