FARMERS have been warned about taking precautions when emptying slurry stores after a number of incidences of fish being killed in pollution incidents.

Natural Resources Wales (NRW) is investigating four incidents across South Wales after receiving several reports of pollution.

Three pollution incidents in South West Wales are believed to be from agricultural slurry spreading activities.

A further unrelated pollution incident which has caused a significant fish kill is being investigated and has been traced to a business park near Llantrisant Vale of Glamorgan.

Huwel Manley, operations manager for NRW, said: “Whilst we understand that farmers are keen to empty slurry stores at this time of year, but we are disappointed that farmers and contractors are not following best practice.

“Spreading slurry in the days before forecasted heavy rain or in wet ground conditions, means that the nutrients in the slurry can be lost and the run-off potentially causing water pollution.

“Our officers will continue to assess the full impact of these latest pollution incidents.

“Our rivers provide a home to rich, diverse and valuable species of plants and animals so it’s important to deal with pollution as quickly as possible.

If anyone sees pollution, dead fish or fish in distress, please report it on the 24 hour incident line 03000 65 3000.
