Natural Resources Wales (NRW) is appealing to local residents for information on a pollution incident that took place on the River Gamman in Nevern, Pembrokeshire.
The incident was reported on January 29 with initial investigations suggesting agricultural effluent or slurry could be the cause.
Officers are on site and will be carrying out biological surveys to test the long and short term effects the pollution will have on the river.
NRW officers are also working with farmers in the area to provide advice and guidance to reduce the risk of pollution from their farms.
Investigations are being carried out to find the source of the pollution and appropriate action will be carried out where necessary.
Robert Phillips, Environment Officer for NRW, said: “Protecting Wales’ rivers, along with the plants and wildlife that inhabit them, is one of our biggest priorities.
“We not only want to repair any damage the pollution may have caused but also stop it at source wherever we can.
“You may see our vehicles around in the coming weeks while we investigate and test the River Gamman.
If anyone has information on the cause of the incident, please get in touch.”
Any information that can help the investigation can be reported to our 24-hour incidents hotline on 03000 65 3000 by quoting incident number 1800505.
