Officers from Natural Resources Wales have identified the cause of an oil spill, which let 3,500 litres of oil into a river near Crickhowell on Thursday.
The cause of the spill has been traced to a disused oil tank.
The incident has already had a significant impact on the stream, killing many fish and affecting people's gardens.
We have traced the cause of the spill to a disused oil tank and have managed to stop the pollution at source. However, the oil that has already escaped into the ground may continue to seep into the stream via the culvert.We will be using more absorbent pads and booms over the weekend to try and contain and clean up as much of the oil as we can. It has already had a significant impact on the stream with around 150 fish already dead, including trout, bullhead and eels, but is so far not affecting the River Usk.We are continuing to investigate this incident and urge anyone who may have information to contact us.
