Commenting after the verdict Dr Milton Matthews, Director of IFI’s North-Western River Basin District said: “Approximately 160 fish, predominantly brown trout, perished in this incident, and that number also included some stickleback and minnow.
“High levels of ammonia in a watercourse are toxic for fish. Fish kill events such as these are extreme ecological events.
“They can have a severe and prolonged impact on native fish stocks due to the loss of locally- adapted, genetically-distinct, fish populations, which may take many years to recover.
“We welcome further engagement with Uisce Éireann. This will ensure that regular visual inspections of wastewater facilities and discharge points, are conducted to minimise the risk of such pollution events reoccurring.”
“This is especially important at times of high temperatures and low water flow.”
