A Castledawson farmer was found guilty and fined £300, plus £19 court costs and an offenders levy of £15 at Magherafelt Magistrates’ Court on Monday.
Mr Adrian Cudden from Magherafelt Road, was fined for making a polluting discharge to a waterway.
On 19 November 2013, Water Quality Inspectors, acting on behalf of the Northern Ireland Environment Agency inspected a waterway at Magherafelt Road, Castledawson and observed heavy fungal growth in the waterway and detected a strong odour of silage effluent. The polluting discharge was traced to farm premises owned by Mr Cudden. The length of waterway impacted by the discharge was approximately 2.5 kilometres.
A sample taken at the time of the incident confirmed that the discharge contained poisonous, noxious or polluting matter which was potentially harmful to fish life in the receiving waterway.
