Officers from Natural Resources Wales (NRW) are investigating after oil has polluted approximately 850 metres of river in Crickhowell, Powys.
NRW received reports earlier today (23 January, 2015) from the South Wales Fire and Rescue Service as well as local people about the pollution, which is causing an oily sheen on top of the water and a strong odour.
Officers attending the scene have managed to identify the source of the pollution in the Cwm Beth tributary, but the oil has since worked its way downstream to affect the main River Usk.
It is estimated that around 3,500 litres of oil has escaped into the river, and the surrounding area, also affecting nearby gardens.
Officers are making efforts to prevent further oil from reaching the river, but the impacts of the pollution are already evident.
Rhys Hughes, from Natural Resources Wales said:
“We are doing all we can to stop the pollution and to reduce its impact on fish and other wildlife which depend on it, as well as the local community who are being affected.
“Our officers have already spotted a few dead fish in the river, but we’re expecting to see more as the pollution moves through the system. Our team have put booms in place in the Cwm Beth to soak up as much of the pollution as possible.
“Our fisheries specialists are also currently conducting a full assessment of the river to help us determine the impact on the wildlife in the river.
“If anyone has any information about the pollution, they should report it to us through our incident hotline on 0800 807060.”
