Natural Resources Wales (NRW) is investigating an oil spill in a Carmarthenshire stream
NRW was called on Tuesday (4 October) to investigate the kerosene leak, which entered Nant Pibwr, Nantycaws from a nearby pipeline.
Specialist contractors are on site to contain the spill and minimise the impact on the environment.
NRW officers are monitoring the local streams and rivers, and working closely with partner agencies at the site.
It is not currently known how much oil has entered the river and surrounding area.
Local people may notice a smell of oil in the area.
Aneurin Cox, South Wales Operational Resources Manager, Natural Resources Wales said:
“Natural Resources Wales is working with partner agencies to assess and minimise the risk to public health and the environment.
“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.
“We are doing all we can to stop the pollution and reduce its impact on fish and other wildlife which depend on the river.
“If you have any information about the incident please report it to our incident hotline on 0800 807060.”
