Three farmers from Co Down have each been fined £500 for discharging pollution into waterways.
Seamus McAteer, of Valley Road, Banbridge, pleaded guilty after an Environment Agency official found a tributary of the River Lagan badly polluted with farm effluent.
The source of the discharge at the junction of Valley Road and Skelton's Cut, Banbridge, in November 2012 was traced to a farm owned by McAteer.
Thomas Lilburn and Olive Lilburn, of Redhill Road, Dromore, pleaded guilty after also polluting a Lagan tributary in January 2013.
A water quality inspector observed the waterway at Clarehill Road, Dromore to be badly polluted with farm effluent, which was traced to a farm owned by Mr and Mrs Lilburn.
The three all appeared at Newry Magistrates' Court yesterday.
They were each ordered to pay £22 in court costs as well as their £500 fine.
