Final report: No definitive cause of Blackwater pollution that killed 32,000 fish

Despite extensive investigations, no evidence was found of a link between the fish kill and an identifiable pollution incident, or a specific environmental exposure, or waterborne irritant.

A 102-page report into a pollution incident that killed 32,000 salmon and brown trout in the River Blackwater in Cork has found no identifiable cause of the fish kill. 

An inter-agency group, including the Environmental Protection Agency, Inland Fisheries Ireland, Cork County Council and other agencies, has released a final report on what is believed to be Ireland's largest recorded single fish kill.
